To put babylon into ESTree-compatible mode the new plugin `estree` can be enabled. In this mode the parser will output an AST that is compliant to the specs of [ESTree](https://github.com/estree/estree/) + +We highly recommend everyone who uses babylon outside of babel to use this plugin. This will make it much easier for users to switch between different ESTree-compatible parsers. We so far tested several projects with different parsers and exchanged their parser to babylon and in nearly all cases it worked out of the box.

To put babylon into ESTree-compatible mode the new plugin `estree` can be enabled.

This will make it much easier for users to switch between different ESTree-compatible parsers. We so far tested several projects with different parsers and exchanged their parser to babylon and in nearly all cases it worked out of the box. Some other estree-compatible parsers include `acorn`, `esprima`, `espree`, `flow-parser`, etc. + +To enable `estree` mode simply add the plugin in the config: +```json +{ + "plugins": [ "estree" ] +} +``` + +If you want to migrate your project from non-ESTree mode to ESTree, have a look at our [Readme](https://github.com/babel/babylon/#output), where all deviations are mentioned. + +Add a parseExpression public method ([#213](https://github.com/babel/babylon/pull/213)) (jeromew) + +Babylon exports a new function to parse a single expression + +```js +import { parseExpression } from 'babylon'; + +const ast = parseExpression('x || y && z', options); +``` + +The returned AST will only consist of the expression.

To put babylon into ESTree-compatible mode the new plugin `estree` can be enabled. In this mode the parser will output an AST that is compliant to the specs of [ESTree](https://github.com/estree/estree/) + +We highly recommend everyone who uses babylon outside of babel to use this plugin. This will make it much easier for users to switch between different ESTree-compatible parsers. We so far tested several projects with different parsers and exchanged their parser to babylon and in nearly all cases it worked out of the box. Some other estree-compatible parsers include `acorn`, `esprima`, `espree`, `flow-parser`, etc. + +To enable `estree` mode simply add the plugin in the config: +```json +{ + "plugins": [ "estree" ] +} +``` + +If you want to migrate your project from non-ESTree mode to ESTree, have a look at our [Readme](https://github.com/babel/babylon/#output), where all deviations are mentioned. + +Add a parseExpression public method ([#213](https://github.com/babel/babylon/pull/213)) (jeromew) + +Babylon exports a new function to parse a single expression + +```js +import { parseExpression } from 'babylon'; + +const ast = parseExpression('x || y && z', options); +``` + +The returned AST will only consist of the expression.

Returns either a +plain object, a string or `undefined`, or throws `YAMLException` on error. By default, does +not support regexps, functions and undefined. This method is safe for untrusted data. + +options: + +- `filename` _(default: null)_ - string to be used as a file path in + error/warning messages. +- `onWarning` _(default: null)_ - function to call on warning messages. + Loader will call this function with an instance of `YAMLException` for each warning. +- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ - specifies a schema to use. + - `FAILSAFE_SCHEMA` - only strings, arrays and plain objects: + http://www.yaml.org/spec/1.2/spec.html#id2802346 + - `JSON_SCHEMA` - all JSON-supported types: + http://www.yaml.org/spec/1.2/spec.html#id2803231 + - `CORE_SCHEMA` - same as `JSON_SCHEMA`: + http://www.yaml.org/spec/1.2/spec.html#id2804923 + - `DEFAULT_SAFE_SCHEMA` - all supported YAML types, without unsafe ones + (`!!js/undefined`, `!!js/regexp` and `!!js/function`): + http://yaml.org/type/ + - `DEFAULT_FULL_SCHEMA` - all supported YAML types. +- `json` _(default: false)_ - compatibility with JSON.parse behaviour. If true, then duplicate keys in a mapping will override values rather than throwing an error. + +NOTE: This function **does not** understand multi-document sources, it throws +exception on those. + +NOTE: JS-YAML **does not** support schema-specific tag resolution restrictions. +So, the JSON schema is not as strictly defined in the YAML specification. +It allows numbers in any notation, use `Null` and `NULL` as `null`, etc. +The core schema also has no such restrictions. It allows binary notation for integers. + + +### load (string [ , options ]) + +**Use with care with untrusted sources**. The same as `safeLoad()` but uses +`DEFAULT_FULL_SCHEMA` by default - adds some JavaScript-specific types: +`!!js/function`, `!!js/regexp` and `!!js/undefined`. For untrusted sources, you +must additionally validate object structure to avoid injections: + +``` javascript +const untrusted_code = '"toString": ! "function (){very_evil_thing();}"'; + +// I'm just converting that string, what could possibly go wrong? +require('js-yaml').load(untrusted_code) + '' +``` + + +### safeLoadAll (string [, iterator] [, options ]) + +Same as `safeLoad()`, but understands multi-document sources. Applies +`iterator` to each document if specified, or returns array of documents. + +``` javascript +const yaml = require('js-yaml'); + +yaml.safeLoadAll(data, function (doc) { + console.log(doc); +}); +``` + + +### loadAll (string [, iterator] [ , options ]) + +Same as `safeLoadAll()` but uses `DEFAULT_FULL_SCHEMA` by default. + + +### safeDump (object [ , options ]) + +Serializes `object` as a YAML document. Uses `DEFAULT_SAFE_SCHEMA`, so it will +throw an exception if you try to dump regexps or functions. However, you can +disable exceptions by setting the `skipInvalid` option to `true`. + +options: + +- `indent` _(default: 2)_ - indentation width to use (in spaces). +- `noArrayIndent` _(default: false)_ - when true, will not add an indentation level to array elements +- `skipInvalid` _(default: false)_ - do not throw on invalid types (like function + in the safe schema) and skip pairs and single values with such types. +- `flowLevel` (default: -1) - specifies level of nesting, when to switch from + block to flow style for collections. -1 means block style everwhere +- `styles` - "tag" => "style" map. Each tag may have own set of styles. +- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ specifies a schema to use. +- `sortKeys` _(default: `false`)_ - if `true`, sort keys when dumping YAML. If a + function, use the function to sort the keys. +- `lineWidth` _(default: `80`)_ - set max line width. +- `noRefs` _(default: `false`)_ - if `true`, don't convert duplicate objects into references +- `noCompatMode` _(default: `false`)_ - if `true` don't try to be compatible with older + yaml versions. Currently: don't quote "yes", "no" and so on, as required for YAML 1.1 +- `condenseFlow` _(default: `false`)_ - if `true` flow sequences will be condensed, omitting the space between `a, b`. Eg. `'[a,b]'`, and omitting the space between `key: value` and quoting the key. Eg. `'{"a":b}'` Can be useful when using yaml for pretty URL query params as spaces are %-encoded. + +The following table show availlable styles (e.g. "canonical", +"binary"...) available for each tag (.e.g. !!null, !!int ...).

The set +of primitive `operators` is: + +* `<` Less than +* `<=` Less than or equal to +* `>` Greater than +* `>=` Greater than or equal to +* `=` Equal. If no operator is specified, then equality is assumed, + so this operator is optional but MAY be included. + +For example, the comparator `>=1.2.7` would match the versions +`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6` +or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and +would match the versions `2.0.0` and `3.1.0`, but not the versions +`1.0.1` or `1.1.0`. + +Comparators can be joined by whitespace to form a `comparator set`, +which is satisfied by the **intersection** of all of the comparators +it includes. + +A range is composed of one or more comparator sets, joined by `||`. A +version matches a range if and only if every comparator in at least +one of the `||`-separated comparator sets is satisfied by the version. + +For example, the range `>=1.2.7 <1.3.0` would match the versions +`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`, +or `1.1.0`. + +The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`, +`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`. + +### Prerelease Tags + +If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then +it will only be allowed to satisfy comparator sets if at least one +comparator with the same `[major, minor, patch]` tuple also has a +prerelease tag. + +For example, the range `>1.2.3-alpha.3` would be allowed to match the +version `1.2.3-alpha.7`, but it would *not* be satisfied by +`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater +than" `1.2.3-alpha.3` according to the SemVer sort rules. The version +range only accepts prerelease tags on the `1.2.3` version. +Version `3.4.5` *would* satisfy the range because it does not have a +prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`. + +The purpose of this behavior is twofold. First, prerelease versions +frequently are updated very quickly, and contain many breaking changes +that are (by the author's design) not yet fit for public consumption. +Therefore, by default, they are excluded from range-matching +semantics. + +Second, a user who has opted into using a prerelease version has +indicated the intent to use *that specific* set of +alpha/beta/rc versions. By including a prerelease tag in the range, +the user is indicating that they are aware of the risk. However, it +is still not appropriate to assume that they have opted into taking a +similar risk on the *next* set of prerelease versions. + +Note that this behavior can be suppressed (treating all prerelease +versions as if they were normal versions, for range-matching) +by setting the `includePrerelease` flag on the options +object to any +[functions](https://github.com/npm/node-semver#functions) that do +range matching. + +#### Prerelease Identifiers + +The method `.inc` takes an additional `identifier` string argument that +will append the value of the string as a prerelease identifier: + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta') +// '1.2.4-beta.0' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta +1.2.4-beta.0 +``` + +Which then can be used to increment further: + +```bash +$ semver 1.2.4-beta.0 -i prerelease +1.2.4-beta.1 +``` + +To get out of the prerelease phase, use the `release` option: + +```bash +$ semver 1.2.4-beta.1 -i release +1.2.4 +``` + +#### Prerelease Identifier Base + +The method `.inc` takes an optional parameter 'identifierBase' string +that will let you let your prerelease number as zero-based or one-based. +Set to `false` to omit the prerelease number altogether. +If you do not specify this parameter, it will default to zero-based. + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', '1') +// '1.2.4-beta.1' +``` + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', false) +// '1.2.4-beta' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n 1 +1.2.4-beta.1 +``` + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n false +1.2.4-beta +``` + +### Advanced Range Syntax + +Advanced range syntax desugars to primitive comparators in +deterministic ways. + +Advanced ranges may be combined in the same way as primitive +comparators using white space or `||`. + +#### Hyphen Ranges `X.Y.Z - A.B.C` + +Specifies an inclusive set. + +* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4` + +If a partial version is provided as the first version in the inclusive +range, then the missing pieces are replaced with zeroes. + +* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4` + +If a partial version is provided as the second version in the +inclusive range, then all versions that start with the supplied parts +of the tuple are accepted, but nothing that would be greater than the +provided tuple parts. + +* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0` +* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0` + +#### X-Ranges `1.2.x` `1.X` `1.2.*` `*` + +Any of `X`, `x`, or `*` may be used to "stand in" for one of the +numeric values in the `[major, minor, patch]` tuple. + +* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless + `includePrerelease` is specified, in which case any version at all + satisfies) +* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version) +* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions) + +A partial version range is treated as an X-Range, so the special +character is in fact optional. + +* `""` (empty string) := `*` := `>=0.0.0` +* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0` +* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0` + +#### Tilde Ranges `~1.2.3` `~1.2` `~1` + +Allows patch-level changes if a minor version is specified on the +comparator.

Sorts in ascending order if passed to `Array.sort()`. +* `rcompare(v1, v2)`: The reverse of `compare`. Sorts an array of versions + in descending order when passed to `Array.sort()`. +* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions + are equal. Sorts in ascending order if passed to `Array.sort()`. +* `compareLoose(v1, v2)`: Short for `compare(v1, v2, { loose: true })`. +* `diff(v1, v2)`: Returns the difference between two versions by the release type + (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`), + or null if the versions are the same. + +### Sorting + +* `sort(versions)`: Returns a sorted array of versions based on the `compareBuild` + function. +* `rsort(versions)`: The reverse of `sort`.

The + `hilo` argument must be either the string `'>'` or `'<'`. (This is + the function called by `gtr` and `ltr`.) +* `intersects(range)`: Return true if any of the range comparators intersect. +* `simplifyRange(versions, range)`: Return a "simplified" range that + matches the same items in the `versions` list as the range specified. Note + that it does *not* guarantee that it would match the same versions in all + cases, only for the set of versions provided. This is useful when + generating ranges by joining together multiple versions with `||` + programmatically, to provide the user with something a bit more + ergonomic. If the provided range is shorter in string-length than the + generated range, then that is returned. +* `subset(subRange, superRange)`: Return `true` if the `subRange` range is + entirely contained by the `superRange` range. + +Note that, since ranges may be non-contiguous, a version might not be +greater than a range, less than a range, *or* satisfy a range! For +example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9` +until `2.0.0`, so version `1.2.10` would not be greater than the +range (because `2.0.1` satisfies, which is higher), nor less than the +range (since `1.2.8` satisfies, which is lower), and it also does not +satisfy the range. + +If you want to know if a version satisfies or does not satisfy a +range, use the `satisfies(version, range)` function. + +### Coercion + +* `coerce(version, options)`: Coerces a string to semver if possible + +This aims to provide a very forgiving translation of a non-semver string to +semver. It looks for the first digit in a string and consumes all +remaining characters which satisfy at least a partial semver (e.g., `1`, +`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer +versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All +surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes +`3.4.0`). Only text which lacks digits will fail coercion (`version one` +is not valid). The maximum length for any semver component considered for +coercion is 16 characters; longer components will be ignored +(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any +semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value +components are invalid (`9999999999999999.4.7.4` is likely invalid). + +If the `options.rtl` flag is set, then `coerce` will return the right-most +coercible tuple that does not share an ending index with a longer coercible +tuple. For example, `1.2.3.4` will return `2.3.4` in rtl mode, not +`4.0.0`. `1.2.3/4` will return `4.0.0`, because the `4` is not a part of +any other overlapping SemVer tuple. + +If the `options.includePrerelease` flag is set, then the `coerce` result will contain +prerelease and build parts of a version. For example, `1.2.3.4-rc.1+rev.2` +will preserve prerelease `rc.1` and build `rev.2` in the result. + +### Clean + +* `clean(version)`: Clean a string to be a valid semver if possible + +This will return a cleaned and trimmed semver version. If the provided +version is not valid a null will be returned. This does not work for +ranges. + +ex. +* `s.clean(' = v 2.1.5foo')`: `null` +* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean(' = v 2.1.5-foo')`: `null` +* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean('=v2.1.5')`: `'2.1.5'` +* `s.clean(' =v2.1.5')`: `'2.1.5'` +* `s.clean(' 2.1.5 ')`: `'2.1.5'` +* `s.clean('~1.0.0')`: `null` + +## Constants + +As a convenience, helper constants are exported to provide information about what `node-semver` supports: + +### `RELEASE_TYPES` + +- major +- premajor +- minor +- preminor +- patch +- prepatch +- prerelease + +``` +const semver = require('semver'); + +if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) { + console.log('This is a valid release type!'); +} else { + console.warn('This is NOT a valid release type!'); +} +``` + +### `SEMVER_SPEC_VERSION` + +2.0.0 + +``` +const semver = require('semver'); + +console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION); +``` + +## Exported Modules + + + +You may pull in just the part of this semver utility that you need if you +are sensitive to packing and tree-shaking concerns.

The set +of primitive `operators` is: + +* `<` Less than +* `<=` Less than or equal to +* `>` Greater than +* `>=` Greater than or equal to +* `=` Equal. If no operator is specified, then equality is assumed, + so this operator is optional but MAY be included. + +For example, the comparator `>=1.2.7` would match the versions +`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6` +or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and +would match the versions `2.0.0` and `3.1.0`, but not the versions +`1.0.1` or `1.1.0`. + +Comparators can be joined by whitespace to form a `comparator set`, +which is satisfied by the **intersection** of all of the comparators +it includes. + +A range is composed of one or more comparator sets, joined by `||`. A +version matches a range if and only if every comparator in at least +one of the `||`-separated comparator sets is satisfied by the version. + +For example, the range `>=1.2.7 <1.3.0` would match the versions +`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`, +or `1.1.0`. + +The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`, +`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`. + +### Prerelease Tags + +If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then +it will only be allowed to satisfy comparator sets if at least one +comparator with the same `[major, minor, patch]` tuple also has a +prerelease tag. + +For example, the range `>1.2.3-alpha.3` would be allowed to match the +version `1.2.3-alpha.7`, but it would *not* be satisfied by +`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater +than" `1.2.3-alpha.3` according to the SemVer sort rules. The version +range only accepts prerelease tags on the `1.2.3` version. +Version `3.4.5` *would* satisfy the range because it does not have a +prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`. + +The purpose of this behavior is twofold. First, prerelease versions +frequently are updated very quickly, and contain many breaking changes +that are (by the author's design) not yet fit for public consumption. +Therefore, by default, they are excluded from range-matching +semantics. + +Second, a user who has opted into using a prerelease version has +indicated the intent to use *that specific* set of +alpha/beta/rc versions. By including a prerelease tag in the range, +the user is indicating that they are aware of the risk. However, it +is still not appropriate to assume that they have opted into taking a +similar risk on the *next* set of prerelease versions. + +Note that this behavior can be suppressed (treating all prerelease +versions as if they were normal versions, for range-matching) +by setting the `includePrerelease` flag on the options +object to any +[functions](https://github.com/npm/node-semver#functions) that do +range matching. + +#### Prerelease Identifiers + +The method `.inc` takes an additional `identifier` string argument that +will append the value of the string as a prerelease identifier: + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta') +// '1.2.4-beta.0' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta +1.2.4-beta.0 +``` + +Which then can be used to increment further: + +```bash +$ semver 1.2.4-beta.0 -i prerelease +1.2.4-beta.1 +``` + +To get out of the prerelease phase, use the `release` option: + +```bash +$ semver 1.2.4-beta.1 -i release +1.2.4 +``` + +#### Prerelease Identifier Base + +The method `.inc` takes an optional parameter 'identifierBase' string +that will let you let your prerelease number as zero-based or one-based. +Set to `false` to omit the prerelease number altogether. +If you do not specify this parameter, it will default to zero-based. + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', '1') +// '1.2.4-beta.1' +``` + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', false) +// '1.2.4-beta' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n 1 +1.2.4-beta.1 +``` + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n false +1.2.4-beta +``` + +### Advanced Range Syntax + +Advanced range syntax desugars to primitive comparators in +deterministic ways. + +Advanced ranges may be combined in the same way as primitive +comparators using white space or `||`. + +#### Hyphen Ranges `X.Y.Z - A.B.C` + +Specifies an inclusive set. + +* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4` + +If a partial version is provided as the first version in the inclusive +range, then the missing pieces are replaced with zeroes. + +* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4` + +If a partial version is provided as the second version in the +inclusive range, then all versions that start with the supplied parts +of the tuple are accepted, but nothing that would be greater than the +provided tuple parts. + +* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0` +* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0` + +#### X-Ranges `1.2.x` `1.X` `1.2.*` `*` + +Any of `X`, `x`, or `*` may be used to "stand in" for one of the +numeric values in the `[major, minor, patch]` tuple. + +* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless + `includePrerelease` is specified, in which case any version at all + satisfies) +* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version) +* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions) + +A partial version range is treated as an X-Range, so the special +character is in fact optional. + +* `""` (empty string) := `*` := `>=0.0.0` +* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0` +* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0` + +#### Tilde Ranges `~1.2.3` `~1.2` `~1` + +Allows patch-level changes if a minor version is specified on the +comparator.

Sorts in ascending order if passed to `Array.sort()`. +* `rcompare(v1, v2)`: The reverse of `compare`. Sorts an array of versions + in descending order when passed to `Array.sort()`. +* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions + are equal. Sorts in ascending order if passed to `Array.sort()`. +* `compareLoose(v1, v2)`: Short for `compare(v1, v2, { loose: true })`. +* `diff(v1, v2)`: Returns the difference between two versions by the release type + (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`), + or null if the versions are the same. + +### Sorting + +* `sort(versions)`: Returns a sorted array of versions based on the `compareBuild` + function. +* `rsort(versions)`: The reverse of `sort`.

The + `hilo` argument must be either the string `'>'` or `'<'`. (This is + the function called by `gtr` and `ltr`.) +* `intersects(range)`: Return true if any of the range comparators intersect. +* `simplifyRange(versions, range)`: Return a "simplified" range that + matches the same items in the `versions` list as the range specified. Note + that it does *not* guarantee that it would match the same versions in all + cases, only for the set of versions provided. This is useful when + generating ranges by joining together multiple versions with `||` + programmatically, to provide the user with something a bit more + ergonomic. If the provided range is shorter in string-length than the + generated range, then that is returned. +* `subset(subRange, superRange)`: Return `true` if the `subRange` range is + entirely contained by the `superRange` range. + +Note that, since ranges may be non-contiguous, a version might not be +greater than a range, less than a range, *or* satisfy a range! For +example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9` +until `2.0.0`, so version `1.2.10` would not be greater than the +range (because `2.0.1` satisfies, which is higher), nor less than the +range (since `1.2.8` satisfies, which is lower), and it also does not +satisfy the range. + +If you want to know if a version satisfies or does not satisfy a +range, use the `satisfies(version, range)` function. + +### Coercion + +* `coerce(version, options)`: Coerces a string to semver if possible + +This aims to provide a very forgiving translation of a non-semver string to +semver. It looks for the first digit in a string and consumes all +remaining characters which satisfy at least a partial semver (e.g., `1`, +`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer +versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All +surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes +`3.4.0`). Only text which lacks digits will fail coercion (`version one` +is not valid). The maximum length for any semver component considered for +coercion is 16 characters; longer components will be ignored +(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any +semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value +components are invalid (`9999999999999999.4.7.4` is likely invalid). + +If the `options.rtl` flag is set, then `coerce` will return the right-most +coercible tuple that does not share an ending index with a longer coercible +tuple. For example, `1.2.3.4` will return `2.3.4` in rtl mode, not +`4.0.0`. `1.2.3/4` will return `4.0.0`, because the `4` is not a part of +any other overlapping SemVer tuple. + +If the `options.includePrerelease` flag is set, then the `coerce` result will contain +prerelease and build parts of a version. For example, `1.2.3.4-rc.1+rev.2` +will preserve prerelease `rc.1` and build `rev.2` in the result. + +### Clean + +* `clean(version)`: Clean a string to be a valid semver if possible + +This will return a cleaned and trimmed semver version. If the provided +version is not valid a null will be returned. This does not work for +ranges. + +ex. +* `s.clean(' = v 2.1.5foo')`: `null` +* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean(' = v 2.1.5-foo')`: `null` +* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean('=v2.1.5')`: `'2.1.5'` +* `s.clean(' =v2.1.5')`: `'2.1.5'` +* `s.clean(' 2.1.5 ')`: `'2.1.5'` +* `s.clean('~1.0.0')`: `null` + +## Constants + +As a convenience, helper constants are exported to provide information about what `node-semver` supports: + +### `RELEASE_TYPES` + +- major +- premajor +- minor +- preminor +- patch +- prepatch +- prerelease + +``` +const semver = require('semver'); + +if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) { + console.log('This is a valid release type!'); +} else { + console.warn('This is NOT a valid release type!'); +} +``` + +### `SEMVER_SPEC_VERSION` + +2.0.0 + +``` +const semver = require('semver'); + +console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION); +``` + +## Exported Modules + + + +You may pull in just the part of this semver utility that you need if you +are sensitive to packing and tree-shaking concerns.

To put babylon into ESTree-compatible mode the new plugin `estree` can be enabled. In this mode the parser will output an AST that is compliant to the specs of [ESTree](https://github.com/estree/estree/) + +We highly recommend everyone who uses babylon outside of babel to use this plugin. This will make it much easier for users to switch between different ESTree-compatible parsers. We so far tested several projects with different parsers and exchanged their parser to babylon and in nearly all cases it worked out of the box. Some other estree-compatible parsers include `acorn`, `esprima`, `espree`, `flow-parser`, etc. + +To enable `estree` mode simply add the plugin in the config: +```json +{ + "plugins": [ "estree" ] +} +``` + +If you want to migrate your project from non-ESTree mode to ESTree, have a look at our [Readme](https://github.com/babel/babylon/#output), where all deviations are mentioned. + +Add a parseExpression public method ([#213](https://github.com/babel/babylon/pull/213)) (jeromew) + +Babylon exports a new function to parse a single expression + +```js +import { parseExpression } from 'babylon'; + +const ast = parseExpression('x || y && z', options); +``` + +The returned AST will only consist of the expression.

R. R. Tolkien' } +// ] +``` + +#### jp.value(obj, pathExpression[, newValue]) + +Returns the value of the first element matching `pathExpression`. If `newValue` is provided, sets the value of the first matching element and returns the new value. + +#### jp.parent(obj, pathExpression) + +Returns the parent of the first matching element. + +#### jp.apply(obj, pathExpression, fn) + +Runs the supplied function `fn` on each matching element, and replaces each matching element with the return value from the function. The function accepts the value of the matching element as its only parameter. Returns matching nodes with their updated values. + + +```javascript +var nodes = jp.apply(data, '$..author', function(value) { return value.toUpperCase() }); +// [ +// { path: ['$', 'store', 'book', 0, 'author'], value: 'NIGEL REES' }, +// { path: ['$', 'store', 'book', 1, 'author'], value: 'EVELYN WAUGH' }, +// { path: ['$', 'store', 'book', 2, 'author'], value: 'HERMAN MELVILLE' }, +// { path: ['$', 'store', 'book', 3, 'author'], value: 'J.

The supplied path may either be a flat array of keys, as returned by `jp.nodes` for example, or may alternatively be a fully parsed path expression in the form of an array of path components as returned by `jp.parse`. + +```javascript +var pathExpression = jp.stringify(['$', 'store', 'book', 0, 'author']); +// "$.store.book[0].author" +``` + +## Differences from Original Implementation + +This implementation aims to be compatible with Stefan Goessner's original implementation with a few notable exceptions described below. + +#### Evaluating Script Expressions + +Script expressions (i.e, `(...)` and `?(...)`) are statically evaluated via [static-eval](https://github.com/substack/static-eval) rather than using the underlying script engine directly. That means both that the scope is limited to the instance variable (`@`), and only simple expressions (with no side effects) will be valid. So for example, `?(@.length>10)` will be just fine to match arrays with more than ten elements, but `?(process.exit())` will not get evaluated since `process` would yield a `ReferenceError`. This method is even safer than `vm.runInNewContext`, since the script engine itself is more limited and entirely distinct from the one running the application code. See more details in the [implementation](https://github.com/substack/static-eval/blob/master/index.js) of the evaluator. + +#### Grammar + +This project uses a formal BNF [grammar](https://github.com/dchester/jsonpath/blob/master/lib/grammar.js) to parse JSONPath expressions, an attempt at reverse-engineering the intent of the original implementation, which parses via a series of creative regular expressions. The original regex approach can sometimes be forgiving for better or for worse (e.g., `$['store]` => `$['store']`), and in other cases, can be just plain wrong (e.g. `[` => `$`). + +#### Other Minor Differences + +As a result of using a real parser and static evaluation, there are some arguable bugs in the original library that have not been carried through here: + +- strings in subscripts may now be double-quoted +- final `step` arguments in slice operators may now be negative +- script expressions may now contain `.` and `@` characters not referring to instance variables +- subscripts no longer act as character slices on string elements +- non-ascii non-word characters are no-longer valid in member identifier names; use quoted subscript strings instead (e.g., `$['$']` instead of `$.$`) +- unions now yield real unions with no duplicates rather than concatenated results + +## License + +[MIT](LICENSE) + diff --git a/node_modules/actions-secret-parser/node_modules/jsonpath/fig.yml b/node_modules/actions-secret-parser/node_modules/jsonpath/fig.yml new file mode 100644 index 000000000..97e0c5bb7 --- /dev/null +++ b/node_modules/actions-secret-parser/node_modules/jsonpath/fig.yml @@ -0,0 +1,5 @@ +test: + build: . + command: node /usr/src/app/node_modules/.bin/mocha -u tdd test/ + volumes: + - .:/usr/src/app diff --git a/node_modules/actions-secret-parser/node_modules/jsonpath/generated/parser.js b/node_modules/actions-secret-parser/node_modules/jsonpath/generated/parser.js new file mode 100644 index 000000000..02de9cc71 --- /dev/null +++ b/node_modules/actions-secret-parser/node_modules/jsonpath/generated/parser.js @@ -0,0 +1,721 @@ +/* parser generated by jison 0.4.13 */ +/* + Returns a Parser object of the following structure: + + Parser: { + yy: {} + } + + Parser.prototype: { + yy: {}, + trace: function(), + symbols_: {associative list: name ==> number}, + terminals_: {associative list: number ==> name}, + productions_: [...], + performAction: function anonymous(yytext, yyleng, yylineno, yy, yystate, $$, _$), + table: [...], + defaultActions: {...}, + parseError: function(str, hash), + parse: function(input), + + lexer: { + EOF: 1, + parseError: function(str, hash), + setInput: function(input), + input: function(), + unput: function(str), + more: function(), + less: function(n), + pastInput: function(), + upcomingInput: function(), + showPosition: function(), + test_match: function(regex_match_array, rule_index), + next: function(), + lex: function(), + begin: function(condition), + popState: function(), + _currentRules: function(), + topState: function(), + pushState: function(condition), + + options: { + ranges: boolean (optional: true ==> token location info will include a .range[] member) + flex: boolean (optional: true ==> flex-like lexing behaviour where the rules are tested exhaustively to find the longest match) + backtrack_lexer: boolean (optional: true ==> lexer regexes are tested in order and for each matching regex the action code is invoked;

The Right Way, and the Wrong Way. + +The Wrong Way is to sit down and write an option parser. We've all done +that. + +The Right Way is to write some complex configurable program with so many +options that you hit the limit of your frustration just trying to +manage them all, and defer it with duct-tape solutions until you see +exactly to the core of the problem, and finally snap and write an +awesome option parser. + +If you want to write an option parser, don't write an option parser. +Write a package manager, or a source control system, or a service +restarter, or an operating system. You probably won't end up with a +good one of those, but if you don't give up, and you are relentless and +diligent enough in your procrastination, you may just end up with a very +nice option parser. + +## USAGE + + // my-program.js + var nopt = require("nopt") + , Stream = require("stream").Stream + , path = require("path") + , knownOpts = { "foo" : [String, null] + , "bar" : [Stream, Number] + , "baz" : path + , "bloo" : [ "big", "medium", "small" ] + , "flag" : Boolean + , "pick" : Boolean + , "many1" : [String, Array] + , "many2" : [path] + } + , shortHands = { "foofoo" : ["--foo", "Mr. Foo"] + , "b7" : ["--bar", "7"] + , "m" : ["--bloo", "medium"] + , "p" : ["--pick"] + , "f" : ["--flag"] + } + // everything is optional. + // knownOpts and shorthands default to {} + // arg list defaults to process.argv + // slice defaults to 2 + , parsed = nopt(knownOpts, shortHands, process.argv, 2) + console.log(parsed) + +This would give you support for any of the following: + +```bash +$ node my-program.js --foo "blerp" --no-flag +{ "foo" : "blerp", "flag" : false } + +$ node my-program.js ---bar 7 --foo "Mr. Hand" --flag +{ bar: 7, foo: "Mr. Hand", flag: true } + +$ node my-program.js --foo "blerp" -f -----p +{ foo: "blerp", flag: true, pick: true } + +$ node my-program.js -fp --foofoo +{ foo: "Mr. Foo", flag: true, pick: true } + +$ node my-program.js --foofoo -- -fp # -- stops the flag parsing. +{ foo: "Mr. Foo", argv: { remain: ["-fp"] } } + +$ node my-program.js --blatzk -fp # unknown opts are ok. +{ blatzk: true, flag: true, pick: true } + +$ node my-program.js --blatzk=1000 -fp # but you need to use = if they have a value +{ blatzk: 1000, flag: true, pick: true } + +$ node my-program.js --no-blatzk -fp # unless they start with "no-" +{ blatzk: false, flag: true, pick: true } + +$ node my-program.js --baz b/a/z # known paths are resolved. +{ baz: "/Users/isaacs/b/a/z" } + +# if Array is one of the types, then it can take many +# values, and will always be an array.

No parsing is done. +* path: A file system path. Gets resolved against cwd if not absolute. +* url: A url. If it doesn't parse, it isn't accepted. +* Number: Must be numeric. +* Date: Must parse as a date. If it does, and `Date` is one of the options, + then it will return a Date object, not a string. +* Boolean: Must be either `true` or `false`. If an option is a boolean, + then it does not need a value, and its presence will imply `true` as + the value. To negate boolean flags, do `--no-whatever` or `--whatever + false` +* NaN: Means that the option is strictly not allowed. Any value will + fail. +* Stream: An object matching the "Stream" class in node. Valuable + for use when validating programmatically. (npm uses this to let you + supply any WriteStream on the `outfd` and `logfd` config options.) +* Array: If `Array` is specified as one of the types, then the value + will be parsed as a list of options. This means that multiple values + can be specified, and that the value will always be an array. + +If a type is an array of values not on this list, then those are +considered valid values. For instance, in the example above, the +`--bloo` option can only be one of `"big"`, `"medium"`, or `"small"`, +and any other value will be rejected. + +When parsing unknown fields, `"true"`, `"false"`, and `"null"` will be +interpreted as their JavaScript equivalents. + +You can also mix types and values, or multiple types, in a list. For +instance `{ blah: [Number, null] }` would allow a value to be set to +either a Number or null. When types are ordered, this implies a +preference, and the first type that can be used to properly interpret +the value will be used. + +To define a new type, add it to `nopt.typeDefs`. Each item in that +hash is an object with a `type` member and a `validate` method. The +`type` member is an object that matches what goes in the type list. The +`validate` method is a function that gets called with `validate(data, +key, val)`. Validate methods should assign `data[key]` to the valid +value of `val` if it can be handled properly, or return boolean +`false` if it cannot. + +You can also call `nopt.clean(data, types, typeDefs)` to clean up a +config object and remove its invalid properties. + +## Error Handling + +By default, nopt outputs a warning to standard error when invalid values for +known options are found. You can change this behavior by assigning a method +to `nopt.invalidHandler`. This method will be called with +the offending `nopt.invalidHandler(key, val, types)`. + +If no `nopt.invalidHandler` is assigned, then it will console.error +its whining. If it is assigned to boolean `false` then the warning is +suppressed. + +## Abbreviations + +Yes, they are supported. If you define options like this: + +```javascript +{ "foolhardyelephants" : Boolean +, "pileofmonkeys" : Boolean } +``` + +Then this will work: + +```bash +node program.js --foolhar --pil +node program.js --no-f --pileofmon +# etc. +``` + +## Shorthands + +Shorthands are a hash of shorter option names to a snippet of args that +they expand to. + +If multiple one-character shorthands are all combined, and the +combination does not unambiguously match any other option or shorthand, +then they will be broken up into their constituent parts. For example: + +```json +{ "s" : ["--loglevel", "silent"] +, "g" : "--global" +, "f" : "--force" +, "p" : "--parseable" +, "l" : "--long" +} +``` + +```bash +npm ls -sgflp +# just like doing this: +npm ls --loglevel silent --global --force --long --parseable +``` + +## The Rest of the args + +The config object returned by nopt is given a special member called +`argv`, which is an object with the following fields: + +* `remain`: The remaining args after all the parsing has occurred. +* `original`: The args as they originally appeared. +* `cooked`: The args after flags and shorthands are expanded. + +## Slicing + +Node programs are called with more or less the exact argv as it appears +in C land, after the v8 and node-specific options have been plucked off. +As such, `argv[0]` is always `node` and `argv[1]` is always the +JavaScript program being run. + +That's usually not very useful to you.

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. + +module.exports = Transform; + +var Duplex = require('./_stream_duplex'); + +/**/ +var util = require('core-util-is'); +util.inherits = require('inherits'); +/**/ + +util.inherits(Transform, Duplex); + + +function TransformState(options, stream) { + this.afterTransform = function(er, data) { + return afterTransform(stream, er, data); + }; + + this.needTransform = false; + this.transforming = false; + this.writecb = null; + this.writechunk = null; +} + +function afterTransform(stream, er, data) { + var ts = stream._transformState; + ts.transforming = false; + + var cb = ts.writecb; + + if (!cb) + return stream.emit('error', new Error('no writecb in Transform class')); + + ts.writechunk = null; + ts.writecb = null; + + if (!util.isNullOrUndefined(data)) + stream.push(data); + + if (cb) + cb(er); + + var rs = stream._readableState; + rs.reading = false; + if (rs.needReadable || rs.length < rs.highWaterMark) { + stream._read(rs.highWaterMark); + } +} + + +function Transform(options) { + if (!(this instanceof Transform)) + return new Transform(options); + + Duplex.call(this, options); + + this._transformState = new TransformState(options, this); + + // when the writable side finishes, then flush out anything remaining. + var stream = this; + + // start out asking for a readable event once data is transformed. + this._readableState.needReadable = true; + + // we have implemented the _read method, and done the other things + // that Readable wants before the first _read call, so unset the + // sync guard flag. + this._readableState.sync = false; + + this.once('prefinish', function() { + if (util.isFunction(this._flush)) + this._flush(function(er) { + done(stream, er); + }); + else + done(stream); + }); +} + +Transform.prototype.push = function(chunk, encoding) { + this._transformState.needTransform = false; + return Duplex.prototype.push.call(this, chunk, encoding); +}; + +// This is the part where you do stuff! +// override this function in implementation classes. +// 'chunk' is an input chunk. +// +// Call `push(newChunk)` to pass along transformed output +// to the readable side.

Returns an array of paths in the stack. + +### popd([options,] ['-N' | '+N']) + +Available options: + ++ `-n`: Suppresses the normal change of directory when removing directories from the stack, so that only the stack is manipulated. + +Arguments: + ++ `+N`: Removes the Nth directory (counting from the left of the list printed by dirs), starting with zero. ++ `-N`: Removes the Nth directory (counting from the right of the list printed by dirs), starting with zero. + +Examples: + +```javascript +echo(process.cwd()); // '/usr' +pushd('/etc'); // '/etc /usr' +echo(process.cwd()); // '/etc' +popd(); // '/usr' +echo(process.cwd()); // '/usr' +``` + +When no arguments are given, popd removes the top directory from the stack and performs a cd to the new top directory. The elements are numbered from 0 starting at the first directory listed with dirs; i.e., popd is equivalent to popd +0. Returns an array of paths in the stack. + +### dirs([options | '+N' | '-N']) + +Available options: + ++ `-c`: Clears the directory stack by deleting all of the elements. + +Arguments: + ++ `+N`: Displays the Nth directory (counting from the left of the list printed by dirs when invoked without options), starting with zero. ++ `-N`: Displays the Nth directory (counting from the right of the list printed by dirs when invoked without options), starting with zero. + +Display the list of currently remembered directories. Returns an array of paths in the stack, or a single path if +N or -N was specified. + +See also: pushd, popd + + +### ln(options, source, dest) +### ln(source, dest) +Available options: + ++ `s`: symlink ++ `f`: force + +Examples: + +```javascript +ln('file', 'newlink'); +ln('-sf', 'file', 'existing'); +``` + +Links source to dest. Use -f to force the link, should dest already exist. + + +### exit(code) +Exits the current process with the given exit code. + +### env['VAR_NAME'] +Object containing environment variables (both getter and setter). Shortcut to process.env. + +### exec(command [, options] [, callback]) +Available options (all `false` by default): + ++ `async`: Asynchronous execution. Defaults to true if a callback is provided. ++ `silent`: Do not echo program output to console. + +Examples: + +```javascript +var version = exec('node --version', {silent:true}).output; + +var child = exec('some_long_running_process', {async:true}); +child.stdout.on('data', function(data) { + /* ... do something with data ... */ +}); + +exec('some_long_running_process', function(code, output) { + console.log('Exit code:', code); + console.log('Program output:', output); +}); +``` + +Executes the given `command` _synchronously_, unless otherwise specified. +When in synchronous mode returns the object `{ code:..., output:... }`, containing the program's +`output` (stdout + stderr) and its exit `code`. Otherwise returns the child process object, and +the `callback` gets the arguments `(code, output)`. + +**Note:** For long-lived processes, it's best to run `exec()` asynchronously as +the current synchronous implementation uses a lot of CPU. This should be getting +fixed soon. + + +### chmod(octal_mode || octal_string, file) +### chmod(symbolic_mode, file) + +Available options: + ++ `-v`: output a diagnostic for every file processed ++ `-c`: like verbose but report only when a change is made ++ `-R`: change files and directories recursively + +Examples: + +```javascript +chmod(755, '/Users/brandon'); +chmod('755', '/Users/brandon'); // same as above +chmod('u+x', '/Users/brandon'); +``` + +Alters the permissions of a file or directory by either specifying the +absolute permissions in octal form or expressing the changes in symbols. +This command tries to mimic the POSIX behavior as much as possible. +Notable exceptions: + ++ In symbolic modes, 'a-r' and '-r' are identical. No consideration is + given to the umask. ++ There is no "quiet" option since default behavior is to run silent. + + +## Non-Unix commands + + +### tempdir() + +Examples: + +```javascript +var tmp = tempdir(); // "/tmp" for most *nix platforms +``` + +Searches and returns string containing a writeable, platform-dependent temporary directory. +Follows Python's [tempfile algorithm](http://docs.python.org/library/tempfile.html#tempfile.tempdir). + + +### error() +Tests if error occurred in the last command. Returns `null` if no error occurred, +otherwise returns string explaining the error + + +## Configuration + + +### config.silent +Example: + +```javascript +var silentState = config.silent; // save old silent state +config.silent = true; +/* ... */ +config.silent = silentState; // restore old silent state +``` + +Suppresses all command output if `true`, except for `echo()` calls. +Default is `false`. + +### config.fatal +Example: + +```javascript +config.fatal = true; +cp('this_file_does_not_exist', '/dev/null'); // dies here +/* more commands... */ +``` + +If `true` the script will die on errors.

No parsing is done. +* path: A file system path. Gets resolved against cwd if not absolute. +* url: A url. If it doesn't parse, it isn't accepted. +* Number: Must be numeric. +* Date: Must parse as a date. If it does, and `Date` is one of the options, + then it will return a Date object, not a string. +* Boolean: Must be either `true` or `false`. If an option is a boolean, + then it does not need a value, and its presence will imply `true` as + the value. To negate boolean flags, do `--no-whatever` or `--whatever + false` +* NaN: Means that the option is strictly not allowed. Any value will + fail. +* Stream: An object matching the "Stream" class in node. Valuable + for use when validating programmatically. (npm uses this to let you + supply any WriteStream on the `outfd` and `logfd` config options.) +* Array: If `Array` is specified as one of the types, then the value + will be parsed as a list of options. This means that multiple values + can be specified, and that the value will always be an array. + +If a type is an array of values not on this list, then those are +considered valid values. For instance, in the example above, the +`--bloo` option can only be one of `"big"`, `"medium"`, or `"small"`, +and any other value will be rejected. + +When parsing unknown fields, `"true"`, `"false"`, and `"null"` will be +interpreted as their JavaScript equivalents, and numeric values will be +interpreted as a number. + +You can also mix types and values, or multiple types, in a list. For +instance `{ blah: [Number, null] }` would allow a value to be set to +either a Number or null. + +To define a new type, add it to `nopt.typeDefs`. Each item in that +hash is an object with a `type` member and a `validate` method. The +`type` member is an object that matches what goes in the type list. The +`validate` method is a function that gets called with `validate(data, +key, val)`. Validate methods should assign `data[key]` to the valid +value of `val` if it can be handled properly, or return boolean +`false` if it cannot. + +You can also call `nopt.clean(data, types, typeDefs)` to clean up a +config object and remove its invalid properties. + +## Error Handling + +By default, nopt outputs a warning to standard error when invalid +options are found. You can change this behavior by assigning a method +to `nopt.invalidHandler`. This method will be called with +the offending `nopt.invalidHandler(key, val, types)`. + +If no `nopt.invalidHandler` is assigned, then it will console.error +its whining. If it is assigned to boolean `false` then the warning is +suppressed. + +## Abbreviations + +Yes, they are supported. If you define options like this: + +```javascript +{ "foolhardyelephants" : Boolean +, "pileofmonkeys" : Boolean } +``` + +Then this will work: + +```bash +node program.js --foolhar --pil +node program.js --no-f --pileofmon +# etc. +``` + +## Shorthands + +Shorthands are a hash of shorter option names to a snippet of args that +they expand to. + +If multiple one-character shorthands are all combined, and the +combination does not unambiguously match any other option or shorthand, +then they will be broken up into their constituent parts.

To put babylon into ESTree-compatible mode the new plugin `estree` can be enabled.

This will make it much easier for users to switch between different ESTree-compatible parsers. We so far tested several projects with different parsers and exchanged their parser to babylon and in nearly all cases it worked out of the box. Some other estree-compatible parsers include `acorn`, `esprima`, `espree`, `flow-parser`, etc. + +To enable `estree` mode simply add the plugin in the config: +```json +{ + "plugins": [ "estree" ] +} +``` + +If you want to migrate your project from non-ESTree mode to ESTree, have a look at our [Readme](https://github.com/babel/babylon/#output), where all deviations are mentioned. + +Add a parseExpression public method ([#213](https://github.com/babel/babylon/pull/213)) (jeromew) + +Babylon exports a new function to parse a single expression + +```js +import { parseExpression } from 'babylon'; + +const ast = parseExpression('x || y && z', options); +``` + +The returned AST will only consist of the expression.

The set +of primitive `operators` is: + +* `<` Less than +* `<=` Less than or equal to +* `>` Greater than +* `>=` Greater than or equal to +* `=` Equal. If no operator is specified, then equality is assumed, + so this operator is optional but MAY be included. + +For example, the comparator `>=1.2.7` would match the versions +`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6` +or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and +would match the versions `2.0.0` and `3.1.0`, but not the versions +`1.0.1` or `1.1.0`. + +Comparators can be joined by whitespace to form a `comparator set`, +which is satisfied by the **intersection** of all of the comparators +it includes. + +A range is composed of one or more comparator sets, joined by `||`. A +version matches a range if and only if every comparator in at least +one of the `||`-separated comparator sets is satisfied by the version. + +For example, the range `>=1.2.7 <1.3.0` would match the versions +`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`, +or `1.1.0`. + +The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`, +`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`. + +### Prerelease Tags + +If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then +it will only be allowed to satisfy comparator sets if at least one +comparator with the same `[major, minor, patch]` tuple also has a +prerelease tag. + +For example, the range `>1.2.3-alpha.3` would be allowed to match the +version `1.2.3-alpha.7`, but it would *not* be satisfied by +`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater +than" `1.2.3-alpha.3` according to the SemVer sort rules. The version +range only accepts prerelease tags on the `1.2.3` version. +Version `3.4.5` *would* satisfy the range because it does not have a +prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`. + +The purpose of this behavior is twofold. First, prerelease versions +frequently are updated very quickly, and contain many breaking changes +that are (by the author's design) not yet fit for public consumption. +Therefore, by default, they are excluded from range-matching +semantics. + +Second, a user who has opted into using a prerelease version has +indicated the intent to use *that specific* set of +alpha/beta/rc versions. By including a prerelease tag in the range, +the user is indicating that they are aware of the risk. However, it +is still not appropriate to assume that they have opted into taking a +similar risk on the *next* set of prerelease versions. + +Note that this behavior can be suppressed (treating all prerelease +versions as if they were normal versions, for range-matching) +by setting the `includePrerelease` flag on the options +object to any +[functions](https://github.com/npm/node-semver#functions) that do +range matching. + +#### Prerelease Identifiers + +The method `.inc` takes an additional `identifier` string argument that +will append the value of the string as a prerelease identifier: + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta') +// '1.2.4-beta.0' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta +1.2.4-beta.0 +``` + +Which then can be used to increment further: + +```bash +$ semver 1.2.4-beta.0 -i prerelease +1.2.4-beta.1 +``` + +To get out of the prerelease phase, use the `release` option: + +```bash +$ semver 1.2.4-beta.1 -i release +1.2.4 +``` + +#### Prerelease Identifier Base + +The method `.inc` takes an optional parameter 'identifierBase' string +that will let you let your prerelease number as zero-based or one-based. +Set to `false` to omit the prerelease number altogether. +If you do not specify this parameter, it will default to zero-based. + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', '1') +// '1.2.4-beta.1' +``` + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', false) +// '1.2.4-beta' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n 1 +1.2.4-beta.1 +``` + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n false +1.2.4-beta +``` + +### Advanced Range Syntax + +Advanced range syntax desugars to primitive comparators in +deterministic ways. + +Advanced ranges may be combined in the same way as primitive +comparators using white space or `||`. + +#### Hyphen Ranges `X.Y.Z - A.B.C` + +Specifies an inclusive set. + +* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4` + +If a partial version is provided as the first version in the inclusive +range, then the missing pieces are replaced with zeroes. + +* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4` + +If a partial version is provided as the second version in the +inclusive range, then all versions that start with the supplied parts +of the tuple are accepted, but nothing that would be greater than the +provided tuple parts. + +* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0` +* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0` + +#### X-Ranges `1.2.x` `1.X` `1.2.*` `*` + +Any of `X`, `x`, or `*` may be used to "stand in" for one of the +numeric values in the `[major, minor, patch]` tuple. + +* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless + `includePrerelease` is specified, in which case any version at all + satisfies) +* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version) +* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions) + +A partial version range is treated as an X-Range, so the special +character is in fact optional. + +* `""` (empty string) := `*` := `>=0.0.0` +* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0` +* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0` + +#### Tilde Ranges `~1.2.3` `~1.2` `~1` + +Allows patch-level changes if a minor version is specified on the +comparator.

Sorts in ascending order if passed to `Array.sort()`. +* `compareLoose(v1, v2)`: Short for `compare(v1, v2, { loose: true })`. +* `diff(v1, v2)`: Returns the difference between two versions by the release type + (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`), + or null if the versions are the same. + +### Sorting + +* `sort(versions)`: Returns a sorted array of versions based on the `compareBuild` + function. +* `rsort(versions)`: The reverse of `sort`. Returns an array of versions based on + the `compareBuild` function in descending order. + +### Comparators + +* `intersects(comparator)`: Return true if the comparators intersect + +### Ranges + +* `validRange(range)`: Return the valid range or null if it's not valid. +* `satisfies(version, range)`: Return true if the version satisfies the + range. +* `maxSatisfying(versions, range)`: Return the highest version in the list + that satisfies the range, or `null` if none of them do. +* `minSatisfying(versions, range)`: Return the lowest version in the list + that satisfies the range, or `null` if none of them do. +* `minVersion(range)`: Return the lowest version that can match + the given range. +* `gtr(version, range)`: Return `true` if the version is greater than all the + versions possible in the range. +* `ltr(version, range)`: Return `true` if the version is less than all the + versions possible in the range. +* `outside(version, range, hilo)`: Return true if the version is outside + the bounds of the range in either the high or low direction. The + `hilo` argument must be either the string `'>'` or `'<'`. (This is + the function called by `gtr` and `ltr`.) +* `intersects(range)`: Return true if any of the range comparators intersect. +* `simplifyRange(versions, range)`: Return a "simplified" range that + matches the same items in the `versions` list as the range specified. Note + that it does *not* guarantee that it would match the same versions in all + cases, only for the set of versions provided. This is useful when + generating ranges by joining together multiple versions with `||` + programmatically, to provide the user with something a bit more + ergonomic. If the provided range is shorter in string-length than the + generated range, then that is returned. +* `subset(subRange, superRange)`: Return `true` if the `subRange` range is + entirely contained by the `superRange` range. + +Note that, since ranges may be non-contiguous, a version might not be +greater than a range, less than a range, *or* satisfy a range! For +example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9` +until `2.0.0`, so version `1.2.10` would not be greater than the +range (because `2.0.1` satisfies, which is higher), nor less than the +range (since `1.2.8` satisfies, which is lower), and it also does not +satisfy the range. + +If you want to know if a version satisfies or does not satisfy a +range, use the `satisfies(version, range)` function. + +### Coercion + +* `coerce(version, options)`: Coerces a string to semver if possible + +This aims to provide a very forgiving translation of a non-semver string to +semver. It looks for the first digit in a string and consumes all +remaining characters which satisfy at least a partial semver (e.g., `1`, +`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer +versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All +surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes +`3.4.0`). Only text which lacks digits will fail coercion (`version one` +is not valid). The maximum length for any semver component considered for +coercion is 16 characters; longer components will be ignored +(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any +semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value +components are invalid (`9999999999999999.4.7.4` is likely invalid). + +If the `options.rtl` flag is set, then `coerce` will return the right-most +coercible tuple that does not share an ending index with a longer coercible +tuple. For example, `1.2.3.4` will return `2.3.4` in rtl mode, not +`4.0.0`. `1.2.3/4` will return `4.0.0`, because the `4` is not a part of +any other overlapping SemVer tuple. + +If the `options.includePrerelease` flag is set, then the `coerce` result will contain +prerelease and build parts of a version. For example, `1.2.3.4-rc.1+rev.2` +will preserve prerelease `rc.1` and build `rev.2` in the result. + +### Clean + +* `clean(version)`: Clean a string to be a valid semver if possible + +This will return a cleaned and trimmed semver version. If the provided +version is not valid a null will be returned. This does not work for +ranges. + +ex. +* `s.clean(' = v 2.1.5foo')`: `null` +* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean(' = v 2.1.5-foo')`: `null` +* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean('=v2.1.5')`: `'2.1.5'` +* `s.clean(' =v2.1.5')`: `'2.1.5'` +* `s.clean(' 2.1.5 ')`: `'2.1.5'` +* `s.clean('~1.0.0')`: `null` + +## Constants + +As a convenience, helper constants are exported to provide information about what `node-semver` supports: + +### `RELEASE_TYPES` + +- major +- premajor +- minor +- preminor +- patch +- prepatch +- prerelease + +``` +const semver = require('semver'); + +if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) { + console.log('This is a valid release type!'); +} else { + console.warn('This is NOT a valid release type!'); +} +``` + +### `SEMVER_SPEC_VERSION` + +2.0.0 + +``` +const semver = require('semver'); + +console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION); +``` + +## Exported Modules + + + +You may pull in just the part of this semver utility that you need if you +are sensitive to packing and tree-shaking concerns.

The set +of primitive `operators` is: + +* `<` Less than +* `<=` Less than or equal to +* `>` Greater than +* `>=` Greater than or equal to +* `=` Equal. If no operator is specified, then equality is assumed, + so this operator is optional but MAY be included. + +For example, the comparator `>=1.2.7` would match the versions +`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6` +or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and +would match the versions `2.0.0` and `3.1.0`, but not the versions +`1.0.1` or `1.1.0`. + +Comparators can be joined by whitespace to form a `comparator set`, +which is satisfied by the **intersection** of all of the comparators +it includes. + +A range is composed of one or more comparator sets, joined by `||`. A +version matches a range if and only if every comparator in at least +one of the `||`-separated comparator sets is satisfied by the version. + +For example, the range `>=1.2.7 <1.3.0` would match the versions +`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`, +or `1.1.0`. + +The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`, +`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`. + +### Prerelease Tags + +If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then +it will only be allowed to satisfy comparator sets if at least one +comparator with the same `[major, minor, patch]` tuple also has a +prerelease tag. + +For example, the range `>1.2.3-alpha.3` would be allowed to match the +version `1.2.3-alpha.7`, but it would *not* be satisfied by +`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater +than" `1.2.3-alpha.3` according to the SemVer sort rules. The version +range only accepts prerelease tags on the `1.2.3` version. +Version `3.4.5` *would* satisfy the range because it does not have a +prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`. + +The purpose of this behavior is twofold. First, prerelease versions +frequently are updated very quickly, and contain many breaking changes +that are (by the author's design) not yet fit for public consumption. +Therefore, by default, they are excluded from range-matching +semantics. + +Second, a user who has opted into using a prerelease version has +indicated the intent to use *that specific* set of +alpha/beta/rc versions. By including a prerelease tag in the range, +the user is indicating that they are aware of the risk. However, it +is still not appropriate to assume that they have opted into taking a +similar risk on the *next* set of prerelease versions. + +Note that this behavior can be suppressed (treating all prerelease +versions as if they were normal versions, for range-matching) +by setting the `includePrerelease` flag on the options +object to any +[functions](https://github.com/npm/node-semver#functions) that do +range matching. + +#### Prerelease Identifiers + +The method `.inc` takes an additional `identifier` string argument that +will append the value of the string as a prerelease identifier: + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta') +// '1.2.4-beta.0' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta +1.2.4-beta.0 +``` + +Which then can be used to increment further: + +```bash +$ semver 1.2.4-beta.0 -i prerelease +1.2.4-beta.1 +``` + +To get out of the prerelease phase, use the `release` option: + +```bash +$ semver 1.2.4-beta.1 -i release +1.2.4 +``` + +#### Prerelease Identifier Base + +The method `.inc` takes an optional parameter 'identifierBase' string +that will let you let your prerelease number as zero-based or one-based. +Set to `false` to omit the prerelease number altogether. +If you do not specify this parameter, it will default to zero-based. + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', '1') +// '1.2.4-beta.1' +``` + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', false) +// '1.2.4-beta' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n 1 +1.2.4-beta.1 +``` + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n false +1.2.4-beta +``` + +### Advanced Range Syntax + +Advanced range syntax desugars to primitive comparators in +deterministic ways. + +Advanced ranges may be combined in the same way as primitive +comparators using white space or `||`. + +#### Hyphen Ranges `X.Y.Z - A.B.C` + +Specifies an inclusive set. + +* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4` + +If a partial version is provided as the first version in the inclusive +range, then the missing pieces are replaced with zeroes. + +* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4` + +If a partial version is provided as the second version in the +inclusive range, then all versions that start with the supplied parts +of the tuple are accepted, but nothing that would be greater than the +provided tuple parts. + +* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0` +* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0` + +#### X-Ranges `1.2.x` `1.X` `1.2.*` `*` + +Any of `X`, `x`, or `*` may be used to "stand in" for one of the +numeric values in the `[major, minor, patch]` tuple. + +* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless + `includePrerelease` is specified, in which case any version at all + satisfies) +* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version) +* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions) + +A partial version range is treated as an X-Range, so the special +character is in fact optional. + +* `""` (empty string) := `*` := `>=0.0.0` +* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0` +* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0` + +#### Tilde Ranges `~1.2.3` `~1.2` `~1` + +Allows patch-level changes if a minor version is specified on the +comparator.

Sorts in ascending order if passed to `Array.sort()`. +* `rcompare(v1, v2)`: The reverse of `compare`. Sorts an array of versions + in descending order when passed to `Array.sort()`. +* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions + are equal. Sorts in ascending order if passed to `Array.sort()`. +* `compareLoose(v1, v2)`: Short for `compare(v1, v2, { loose: true })`. +* `diff(v1, v2)`: Returns the difference between two versions by the release type + (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`), + or null if the versions are the same. + +### Sorting + +* `sort(versions)`: Returns a sorted array of versions based on the `compareBuild` + function. +* `rsort(versions)`: The reverse of `sort`.

The + `hilo` argument must be either the string `'>'` or `'<'`. (This is + the function called by `gtr` and `ltr`.) +* `intersects(range)`: Return true if any of the range comparators intersect. +* `simplifyRange(versions, range)`: Return a "simplified" range that + matches the same items in the `versions` list as the range specified. Note + that it does *not* guarantee that it would match the same versions in all + cases, only for the set of versions provided. This is useful when + generating ranges by joining together multiple versions with `||` + programmatically, to provide the user with something a bit more + ergonomic. If the provided range is shorter in string-length than the + generated range, then that is returned. +* `subset(subRange, superRange)`: Return `true` if the `subRange` range is + entirely contained by the `superRange` range. + +Note that, since ranges may be non-contiguous, a version might not be +greater than a range, less than a range, *or* satisfy a range! For +example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9` +until `2.0.0`, so version `1.2.10` would not be greater than the +range (because `2.0.1` satisfies, which is higher), nor less than the +range (since `1.2.8` satisfies, which is lower), and it also does not +satisfy the range. + +If you want to know if a version satisfies or does not satisfy a +range, use the `satisfies(version, range)` function. + +### Coercion + +* `coerce(version, options)`: Coerces a string to semver if possible + +This aims to provide a very forgiving translation of a non-semver string to +semver. It looks for the first digit in a string and consumes all +remaining characters which satisfy at least a partial semver (e.g., `1`, +`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer +versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All +surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes +`3.4.0`). Only text which lacks digits will fail coercion (`version one` +is not valid). The maximum length for any semver component considered for +coercion is 16 characters; longer components will be ignored +(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any +semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value +components are invalid (`9999999999999999.4.7.4` is likely invalid). + +If the `options.rtl` flag is set, then `coerce` will return the right-most +coercible tuple that does not share an ending index with a longer coercible +tuple. For example, `1.2.3.4` will return `2.3.4` in rtl mode, not +`4.0.0`. `1.2.3/4` will return `4.0.0`, because the `4` is not a part of +any other overlapping SemVer tuple. + +If the `options.includePrerelease` flag is set, then the `coerce` result will contain +prerelease and build parts of a version. For example, `1.2.3.4-rc.1+rev.2` +will preserve prerelease `rc.1` and build `rev.2` in the result. + +### Clean + +* `clean(version)`: Clean a string to be a valid semver if possible + +This will return a cleaned and trimmed semver version. If the provided +version is not valid a null will be returned. This does not work for +ranges. + +ex. +* `s.clean(' = v 2.1.5foo')`: `null` +* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean(' = v 2.1.5-foo')`: `null` +* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean('=v2.1.5')`: `'2.1.5'` +* `s.clean(' =v2.1.5')`: `'2.1.5'` +* `s.clean(' 2.1.5 ')`: `'2.1.5'` +* `s.clean('~1.0.0')`: `null` + +## Constants + +As a convenience, helper constants are exported to provide information about what `node-semver` supports: + +### `RELEASE_TYPES` + +- major +- premajor +- minor +- preminor +- patch +- prepatch +- prerelease + +``` +const semver = require('semver'); + +if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) { + console.log('This is a valid release type!'); +} else { + console.warn('This is NOT a valid release type!'); +} +``` + +### `SEMVER_SPEC_VERSION` + +2.0.0 + +``` +const semver = require('semver'); + +console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION); +``` + +## Exported Modules + + + +You may pull in just the part of this semver utility that you need if you +are sensitive to packing and tree-shaking concerns.

The set +of primitive `operators` is: + +* `<` Less than +* `<=` Less than or equal to +* `>` Greater than +* `>=` Greater than or equal to +* `=` Equal. If no operator is specified, then equality is assumed, + so this operator is optional but MAY be included. + +For example, the comparator `>=1.2.7` would match the versions +`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6` +or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and +would match the versions `2.0.0` and `3.1.0`, but not the versions +`1.0.1` or `1.1.0`. + +Comparators can be joined by whitespace to form a `comparator set`, +which is satisfied by the **intersection** of all of the comparators +it includes. + +A range is composed of one or more comparator sets, joined by `||`. A +version matches a range if and only if every comparator in at least +one of the `||`-separated comparator sets is satisfied by the version. + +For example, the range `>=1.2.7 <1.3.0` would match the versions +`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`, +or `1.1.0`. + +The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`, +`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`. + +### Prerelease Tags + +If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then +it will only be allowed to satisfy comparator sets if at least one +comparator with the same `[major, minor, patch]` tuple also has a +prerelease tag. + +For example, the range `>1.2.3-alpha.3` would be allowed to match the +version `1.2.3-alpha.7`, but it would *not* be satisfied by +`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater +than" `1.2.3-alpha.3` according to the SemVer sort rules. The version +range only accepts prerelease tags on the `1.2.3` version. +Version `3.4.5` *would* satisfy the range because it does not have a +prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`. + +The purpose of this behavior is twofold. First, prerelease versions +frequently are updated very quickly, and contain many breaking changes +that are (by the author's design) not yet fit for public consumption. +Therefore, by default, they are excluded from range-matching +semantics. + +Second, a user who has opted into using a prerelease version has +indicated the intent to use *that specific* set of +alpha/beta/rc versions. By including a prerelease tag in the range, +the user is indicating that they are aware of the risk. However, it +is still not appropriate to assume that they have opted into taking a +similar risk on the *next* set of prerelease versions. + +Note that this behavior can be suppressed (treating all prerelease +versions as if they were normal versions, for range-matching) +by setting the `includePrerelease` flag on the options +object to any +[functions](https://github.com/npm/node-semver#functions) that do +range matching. + +#### Prerelease Identifiers + +The method `.inc` takes an additional `identifier` string argument that +will append the value of the string as a prerelease identifier: + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta') +// '1.2.4-beta.0' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta +1.2.4-beta.0 +``` + +Which then can be used to increment further: + +```bash +$ semver 1.2.4-beta.0 -i prerelease +1.2.4-beta.1 +``` + +To get out of the prerelease phase, use the `release` option: + +```bash +$ semver 1.2.4-beta.1 -i release +1.2.4 +``` + +#### Prerelease Identifier Base + +The method `.inc` takes an optional parameter 'identifierBase' string +that will let you let your prerelease number as zero-based or one-based. +Set to `false` to omit the prerelease number altogether. +If you do not specify this parameter, it will default to zero-based. + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', '1') +// '1.2.4-beta.1' +``` + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', false) +// '1.2.4-beta' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n 1 +1.2.4-beta.1 +``` + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n false +1.2.4-beta +``` + +### Advanced Range Syntax + +Advanced range syntax desugars to primitive comparators in +deterministic ways. + +Advanced ranges may be combined in the same way as primitive +comparators using white space or `||`. + +#### Hyphen Ranges `X.Y.Z - A.B.C` + +Specifies an inclusive set. + +* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4` + +If a partial version is provided as the first version in the inclusive +range, then the missing pieces are replaced with zeroes. + +* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4` + +If a partial version is provided as the second version in the +inclusive range, then all versions that start with the supplied parts +of the tuple are accepted, but nothing that would be greater than the +provided tuple parts. + +* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0` +* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0` + +#### X-Ranges `1.2.x` `1.X` `1.2.*` `*` + +Any of `X`, `x`, or `*` may be used to "stand in" for one of the +numeric values in the `[major, minor, patch]` tuple. + +* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless + `includePrerelease` is specified, in which case any version at all + satisfies) +* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version) +* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions) + +A partial version range is treated as an X-Range, so the special +character is in fact optional. + +* `""` (empty string) := `*` := `>=0.0.0` +* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0` +* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0` + +#### Tilde Ranges `~1.2.3` `~1.2` `~1` + +Allows patch-level changes if a minor version is specified on the +comparator.

Sorts in ascending order if passed to `Array.sort()`. +* `rcompare(v1, v2)`: The reverse of `compare`. Sorts an array of versions + in descending order when passed to `Array.sort()`. +* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions + are equal. Sorts in ascending order if passed to `Array.sort()`. +* `compareLoose(v1, v2)`: Short for `compare(v1, v2, { loose: true })`. +* `diff(v1, v2)`: Returns the difference between two versions by the release type + (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`), + or null if the versions are the same. + +### Sorting + +* `sort(versions)`: Returns a sorted array of versions based on the `compareBuild` + function. +* `rsort(versions)`: The reverse of `sort`.

The + `hilo` argument must be either the string `'>'` or `'<'`. (This is + the function called by `gtr` and `ltr`.) +* `intersects(range)`: Return true if any of the range comparators intersect. +* `simplifyRange(versions, range)`: Return a "simplified" range that + matches the same items in the `versions` list as the range specified. Note + that it does *not* guarantee that it would match the same versions in all + cases, only for the set of versions provided. This is useful when + generating ranges by joining together multiple versions with `||` + programmatically, to provide the user with something a bit more + ergonomic. If the provided range is shorter in string-length than the + generated range, then that is returned. +* `subset(subRange, superRange)`: Return `true` if the `subRange` range is + entirely contained by the `superRange` range. + +Note that, since ranges may be non-contiguous, a version might not be +greater than a range, less than a range, *or* satisfy a range! For +example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9` +until `2.0.0`, so version `1.2.10` would not be greater than the +range (because `2.0.1` satisfies, which is higher), nor less than the +range (since `1.2.8` satisfies, which is lower), and it also does not +satisfy the range. + +If you want to know if a version satisfies or does not satisfy a +range, use the `satisfies(version, range)` function. + +### Coercion + +* `coerce(version, options)`: Coerces a string to semver if possible + +This aims to provide a very forgiving translation of a non-semver string to +semver. It looks for the first digit in a string and consumes all +remaining characters which satisfy at least a partial semver (e.g., `1`, +`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer +versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All +surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes +`3.4.0`). Only text which lacks digits will fail coercion (`version one` +is not valid). The maximum length for any semver component considered for +coercion is 16 characters; longer components will be ignored +(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any +semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value +components are invalid (`9999999999999999.4.7.4` is likely invalid). + +If the `options.rtl` flag is set, then `coerce` will return the right-most +coercible tuple that does not share an ending index with a longer coercible +tuple. For example, `1.2.3.4` will return `2.3.4` in rtl mode, not +`4.0.0`. `1.2.3/4` will return `4.0.0`, because the `4` is not a part of +any other overlapping SemVer tuple. + +If the `options.includePrerelease` flag is set, then the `coerce` result will contain +prerelease and build parts of a version. For example, `1.2.3.4-rc.1+rev.2` +will preserve prerelease `rc.1` and build `rev.2` in the result. + +### Clean + +* `clean(version)`: Clean a string to be a valid semver if possible + +This will return a cleaned and trimmed semver version. If the provided +version is not valid a null will be returned. This does not work for +ranges. + +ex. +* `s.clean(' = v 2.1.5foo')`: `null` +* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean(' = v 2.1.5-foo')`: `null` +* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean('=v2.1.5')`: `'2.1.5'` +* `s.clean(' =v2.1.5')`: `'2.1.5'` +* `s.clean(' 2.1.5 ')`: `'2.1.5'` +* `s.clean('~1.0.0')`: `null` + +## Constants + +As a convenience, helper constants are exported to provide information about what `node-semver` supports: + +### `RELEASE_TYPES` + +- major +- premajor +- minor +- preminor +- patch +- prepatch +- prerelease + +``` +const semver = require('semver'); + +if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) { + console.log('This is a valid release type!'); +} else { + console.warn('This is NOT a valid release type!'); +} +``` + +### `SEMVER_SPEC_VERSION` + +2.0.0 + +``` +const semver = require('semver'); + +console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION); +``` + +## Exported Modules + + + +You may pull in just the part of this semver utility that you need if you +are sensitive to packing and tree-shaking concerns.

The set +of primitive `operators` is: + +* `<` Less than +* `<=` Less than or equal to +* `>` Greater than +* `>=` Greater than or equal to +* `=` Equal. If no operator is specified, then equality is assumed, + so this operator is optional but MAY be included. + +For example, the comparator `>=1.2.7` would match the versions +`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6` +or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and +would match the versions `2.0.0` and `3.1.0`, but not the versions +`1.0.1` or `1.1.0`. + +Comparators can be joined by whitespace to form a `comparator set`, +which is satisfied by the **intersection** of all of the comparators +it includes. + +A range is composed of one or more comparator sets, joined by `||`. A +version matches a range if and only if every comparator in at least +one of the `||`-separated comparator sets is satisfied by the version. + +For example, the range `>=1.2.7 <1.3.0` would match the versions +`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`, +or `1.1.0`. + +The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`, +`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`. + +### Prerelease Tags + +If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then +it will only be allowed to satisfy comparator sets if at least one +comparator with the same `[major, minor, patch]` tuple also has a +prerelease tag. + +For example, the range `>1.2.3-alpha.3` would be allowed to match the +version `1.2.3-alpha.7`, but it would *not* be satisfied by +`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater +than" `1.2.3-alpha.3` according to the SemVer sort rules. The version +range only accepts prerelease tags on the `1.2.3` version. +Version `3.4.5` *would* satisfy the range because it does not have a +prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`. + +The purpose of this behavior is twofold. First, prerelease versions +frequently are updated very quickly, and contain many breaking changes +that are (by the author's design) not yet fit for public consumption. +Therefore, by default, they are excluded from range-matching +semantics. + +Second, a user who has opted into using a prerelease version has +indicated the intent to use *that specific* set of +alpha/beta/rc versions. By including a prerelease tag in the range, +the user is indicating that they are aware of the risk. However, it +is still not appropriate to assume that they have opted into taking a +similar risk on the *next* set of prerelease versions. + +Note that this behavior can be suppressed (treating all prerelease +versions as if they were normal versions, for range-matching) +by setting the `includePrerelease` flag on the options +object to any +[functions](https://github.com/npm/node-semver#functions) that do +range matching. + +#### Prerelease Identifiers + +The method `.inc` takes an additional `identifier` string argument that +will append the value of the string as a prerelease identifier: + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta') +// '1.2.4-beta.0' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta +1.2.4-beta.0 +``` + +Which then can be used to increment further: + +```bash +$ semver 1.2.4-beta.0 -i prerelease +1.2.4-beta.1 +``` + +To get out of the prerelease phase, use the `release` option: + +```bash +$ semver 1.2.4-beta.1 -i release +1.2.4 +``` + +#### Prerelease Identifier Base + +The method `.inc` takes an optional parameter 'identifierBase' string +that will let you let your prerelease number as zero-based or one-based. +Set to `false` to omit the prerelease number altogether. +If you do not specify this parameter, it will default to zero-based. + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', '1') +// '1.2.4-beta.1' +``` + +```javascript +semver.inc('1.2.3', 'prerelease', 'beta', false) +// '1.2.4-beta' +``` + +command-line example: + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n 1 +1.2.4-beta.1 +``` + +```bash +$ semver 1.2.3 -i prerelease --preid beta -n false +1.2.4-beta +``` + +### Advanced Range Syntax + +Advanced range syntax desugars to primitive comparators in +deterministic ways. + +Advanced ranges may be combined in the same way as primitive +comparators using white space or `||`. + +#### Hyphen Ranges `X.Y.Z - A.B.C` + +Specifies an inclusive set. + +* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4` + +If a partial version is provided as the first version in the inclusive +range, then the missing pieces are replaced with zeroes. + +* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4` + +If a partial version is provided as the second version in the +inclusive range, then all versions that start with the supplied parts +of the tuple are accepted, but nothing that would be greater than the +provided tuple parts. + +* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0` +* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0` + +#### X-Ranges `1.2.x` `1.X` `1.2.*` `*` + +Any of `X`, `x`, or `*` may be used to "stand in" for one of the +numeric values in the `[major, minor, patch]` tuple. + +* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless + `includePrerelease` is specified, in which case any version at all + satisfies) +* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version) +* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions) + +A partial version range is treated as an X-Range, so the special +character is in fact optional. + +* `""` (empty string) := `*` := `>=0.0.0` +* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0` +* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0` + +#### Tilde Ranges `~1.2.3` `~1.2` `~1` + +Allows patch-level changes if a minor version is specified on the +comparator.

Sorts in ascending order if passed to `Array.sort()`. +* `rcompare(v1, v2)`: The reverse of `compare`. Sorts an array of versions + in descending order when passed to `Array.sort()`. +* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions + are equal. Sorts in ascending order if passed to `Array.sort()`. +* `compareLoose(v1, v2)`: Short for `compare(v1, v2, { loose: true })`. +* `diff(v1, v2)`: Returns the difference between two versions by the release type + (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`), + or null if the versions are the same. + +### Sorting + +* `sort(versions)`: Returns a sorted array of versions based on the `compareBuild` + function. +* `rsort(versions)`: The reverse of `sort`.

The + `hilo` argument must be either the string `'>'` or `'<'`. (This is + the function called by `gtr` and `ltr`.) +* `intersects(range)`: Return true if any of the range comparators intersect. +* `simplifyRange(versions, range)`: Return a "simplified" range that + matches the same items in the `versions` list as the range specified. Note + that it does *not* guarantee that it would match the same versions in all + cases, only for the set of versions provided. This is useful when + generating ranges by joining together multiple versions with `||` + programmatically, to provide the user with something a bit more + ergonomic. If the provided range is shorter in string-length than the + generated range, then that is returned. +* `subset(subRange, superRange)`: Return `true` if the `subRange` range is + entirely contained by the `superRange` range. + +Note that, since ranges may be non-contiguous, a version might not be +greater than a range, less than a range, *or* satisfy a range! For +example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9` +until `2.0.0`, so version `1.2.10` would not be greater than the +range (because `2.0.1` satisfies, which is higher), nor less than the +range (since `1.2.8` satisfies, which is lower), and it also does not +satisfy the range. + +If you want to know if a version satisfies or does not satisfy a +range, use the `satisfies(version, range)` function. + +### Coercion + +* `coerce(version, options)`: Coerces a string to semver if possible + +This aims to provide a very forgiving translation of a non-semver string to +semver. It looks for the first digit in a string and consumes all +remaining characters which satisfy at least a partial semver (e.g., `1`, +`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer +versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All +surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes +`3.4.0`). Only text which lacks digits will fail coercion (`version one` +is not valid). The maximum length for any semver component considered for +coercion is 16 characters; longer components will be ignored +(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any +semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value +components are invalid (`9999999999999999.4.7.4` is likely invalid). + +If the `options.rtl` flag is set, then `coerce` will return the right-most +coercible tuple that does not share an ending index with a longer coercible +tuple. For example, `1.2.3.4` will return `2.3.4` in rtl mode, not +`4.0.0`. `1.2.3/4` will return `4.0.0`, because the `4` is not a part of +any other overlapping SemVer tuple. + +If the `options.includePrerelease` flag is set, then the `coerce` result will contain +prerelease and build parts of a version. For example, `1.2.3.4-rc.1+rev.2` +will preserve prerelease `rc.1` and build `rev.2` in the result. + +### Clean + +* `clean(version)`: Clean a string to be a valid semver if possible + +This will return a cleaned and trimmed semver version. If the provided +version is not valid a null will be returned. This does not work for +ranges. + +ex. +* `s.clean(' = v 2.1.5foo')`: `null` +* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean(' = v 2.1.5-foo')`: `null` +* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'` +* `s.clean('=v2.1.5')`: `'2.1.5'` +* `s.clean(' =v2.1.5')`: `'2.1.5'` +* `s.clean(' 2.1.5 ')`: `'2.1.5'` +* `s.clean('~1.0.0')`: `null` + +## Constants + +As a convenience, helper constants are exported to provide information about what `node-semver` supports: + +### `RELEASE_TYPES` + +- major +- premajor +- minor +- preminor +- patch +- prepatch +- prerelease + +``` +const semver = require('semver'); + +if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) { + console.log('This is a valid release type!'); +} else { + console.warn('This is NOT a valid release type!'); +} +``` + +### `SEMVER_SPEC_VERSION` + +2.0.0 + +``` +const semver = require('semver'); + +console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION); +``` + +## Exported Modules + + + +You may pull in just the part of this semver utility that you need if you +are sensitive to packing and tree-shaking concerns.

The set -of primitive `operators` is: - -* `<` Less than -* `<=` Less than or equal to -* `>` Greater than -* `>=` Greater than or equal to -* `=` Equal. If no operator is specified, then equality is assumed, - so this operator is optional but MAY be included. - -For example, the comparator `>=1.2.7` would match the versions -`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6` -or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and -would match the versions `2.0.0` and `3.1.0`, but not the versions -`1.0.1` or `1.1.0`. - -Comparators can be joined by whitespace to form a `comparator set`, -which is satisfied by the **intersection** of all of the comparators -it includes. - -A range is composed of one or more comparator sets, joined by `||`. A -version matches a range if and only if every comparator in at least -one of the `||`-separated comparator sets is satisfied by the version. - -For example, the range `>=1.2.7 <1.3.0` would match the versions -`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`, -or `1.1.0`. - -The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`, -`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`. - -### Prerelease Tags - -If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then -it will only be allowed to satisfy comparator sets if at least one -comparator with the same `[major, minor, patch]` tuple also has a -prerelease tag. - -For example, the range `>1.2.3-alpha.3` would be allowed to match the -version `1.2.3-alpha.7`, but it would *not* be satisfied by -`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater -than" `1.2.3-alpha.3` according to the SemVer sort rules. The version -range only accepts prerelease tags on the `1.2.3` version. -Version `3.4.5` *would* satisfy the range because it does not have a -prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`. - -The purpose of this behavior is twofold. First, prerelease versions -frequently are updated very quickly, and contain many breaking changes -that are (by the author's design) not yet fit for public consumption. -Therefore, by default, they are excluded from range-matching -semantics. - -Second, a user who has opted into using a prerelease version has -indicated the intent to use *that specific* set of -alpha/beta/rc versions. By including a prerelease tag in the range, -the user is indicating that they are aware of the risk. However, it -is still not appropriate to assume that they have opted into taking a -similar risk on the *next* set of prerelease versions. - -Note that this behavior can be suppressed (treating all prerelease -versions as if they were normal versions, for range-matching) -by setting the `includePrerelease` flag on the options -object to any -[functions](https://github.com/npm/node-semver#functions) that do -range matching. - -#### Prerelease Identifiers - -The method `.inc` takes an additional `identifier` string argument that -will append the value of the string as a prerelease identifier: - -```javascript -semver.inc('1.2.3', 'prerelease', 'beta') -// '1.2.4-beta.0' -``` - -command-line example: - -```bash -$ semver 1.2.3 -i prerelease --preid beta -1.2.4-beta.0 -``` - -Which then can be used to increment further: - -```bash -$ semver 1.2.4-beta.0 -i prerelease -1.2.4-beta.1 -``` - -To get out of the prerelease phase, use the `release` option: - -```bash -$ semver 1.2.4-beta.1 -i release -1.2.4 -``` - -#### Prerelease Identifier Base - -The method `.inc` takes an optional parameter 'identifierBase' string -that will let you let your prerelease number as zero-based or one-based. -Set to `false` to omit the prerelease number altogether. -If you do not specify this parameter, it will default to zero-based. - -```javascript -semver.inc('1.2.3', 'prerelease', 'beta', '1') -// '1.2.4-beta.1' -``` - -```javascript -semver.inc('1.2.3', 'prerelease', 'beta', false) -// '1.2.4-beta' -``` - -command-line example: - -```bash -$ semver 1.2.3 -i prerelease --preid beta -n 1 -1.2.4-beta.1 -``` - -```bash -$ semver 1.2.3 -i prerelease --preid beta -n false -1.2.4-beta -``` - -### Advanced Range Syntax - -Advanced range syntax desugars to primitive comparators in -deterministic ways. - -Advanced ranges may be combined in the same way as primitive -comparators using white space or `||`. - -#### Hyphen Ranges `X.Y.Z - A.B.C` - -Specifies an inclusive set. - -* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4` - -If a partial version is provided as the first version in the inclusive -range, then the missing pieces are replaced with zeroes. - -* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4` - -If a partial version is provided as the second version in the -inclusive range, then all versions that start with the supplied parts -of the tuple are accepted, but nothing that would be greater than the -provided tuple parts. - -* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0` -* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0` - -#### X-Ranges `1.2.x` `1.X` `1.2.*` `*` - -Any of `X`, `x`, or `*` may be used to "stand in" for one of the -numeric values in the `[major, minor, patch]` tuple. - -* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless - `includePrerelease` is specified, in which case any version at all - satisfies) -* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version) -* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions) - -A partial version range is treated as an X-Range, so the special -character is in fact optional. - -* `""` (empty string) := `*` := `>=0.0.0` -* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0` -* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0` - -#### Tilde Ranges `~1.2.3` `~1.2` `~1` - -Allows patch-level changes if a minor version is specified on the -comparator.

All -options in this object are `false` by default. The options supported -are: - -- `loose`: Be more forgiving about not-quite-valid semver strings. - (Any resulting output will always be 100% strict compliant, of - course.) For backwards compatibility reasons, if the `options` - argument is a boolean value instead of an object, it is interpreted - to be the `loose` param. -- `includePrerelease`: Set to suppress the [default - behavior](https://github.com/npm/node-semver#prerelease-tags) of - excluding prerelease tagged versions from ranges unless they are - explicitly opted into. - -Strict-mode Comparators and Ranges will be strict about the SemVer -strings that they parse. - -* `valid(v)`: Return the parsed version, or null if it's not valid. -* `inc(v, releaseType, options, identifier, identifierBase)`: - Return the version incremented by the release - type (`major`, `premajor`, `minor`, `preminor`, `patch`, - `prepatch`, `prerelease`, or `release`), or null if it's not valid - * `premajor` in one call will bump the version up to the next major - version and down to a prerelease of that major version. - `preminor`, and `prepatch` work the same way. - * If called from a non-prerelease version, `prerelease` will work the - same as `prepatch`. It increments the patch version and then makes a - prerelease. If the input version is already a prerelease it simply - increments it. - * `release` will remove any prerelease part of the version. - * `identifier` can be used to prefix `premajor`, `preminor`, - `prepatch`, or `prerelease` version increments. `identifierBase` - is the base to be used for the `prerelease` identifier. -* `prerelease(v)`: Returns an array of prerelease components, or null - if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]` -* `major(v)`: Return the major version number. -* `minor(v)`: Return the minor version number. -* `patch(v)`: Return the patch version number. -* `intersects(r1, r2, loose)`: Return true if the two supplied ranges - or comparators intersect. -* `parse(v)`: Attempt to parse a string as a semantic version, returning either - a `SemVer` object or `null`. - -### Comparison - -* `gt(v1, v2)`: `v1 > v2` -* `gte(v1, v2)`: `v1 >= v2` -* `lt(v1, v2)`: `v1 < v2` -* `lte(v1, v2)`: `v1 <= v2` -* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent, - even if they're not the same string. You already know how to - compare strings. -* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`. -* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call - the corresponding function above. `"==="` and `"!=="` do simple - string comparison, but are included for completeness. Throws if an - invalid comparison string is provided. -* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if - `v2` is greater. Sorts in ascending order if passed to `Array.sort()`. -* `rcompare(v1, v2)`: The reverse of `compare`. Sorts an array of versions - in descending order when passed to `Array.sort()`. -* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions - are equal. Sorts in ascending order if passed to `Array.sort()`. -* `compareLoose(v1, v2)`: Short for `compare(v1, v2, { loose: true })`. -* `diff(v1, v2)`: Returns the difference between two versions by the release type - (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`), - or null if the versions are the same. - -### Sorting - -* `sort(versions)`: Returns a sorted array of versions based on the `compareBuild` - function. -* `rsort(versions)`: The reverse of `sort`. Returns an array of versions based on - the `compareBuild` function in descending order. - -### Comparators - -* `intersects(comparator)`: Return true if the comparators intersect - -### Ranges - -* `validRange(range)`: Return the valid range or null if it's not valid. -* `satisfies(version, range)`: Return true if the version satisfies the - range. -* `maxSatisfying(versions, range)`: Return the highest version in the list - that satisfies the range, or `null` if none of them do. -* `minSatisfying(versions, range)`: Return the lowest version in the list - that satisfies the range, or `null` if none of them do. -* `minVersion(range)`: Return the lowest version that can match - the given range. -* `gtr(version, range)`: Return `true` if the version is greater than all the - versions possible in the range. -* `ltr(version, range)`: Return `true` if the version is less than all the - versions possible in the range. -* `outside(version, range, hilo)`: Return true if the version is outside - the bounds of the range in either the high or low direction. The - `hilo` argument must be either the string `'>'` or `'<'`. (This is - the function called by `gtr` and `ltr`.) -* `intersects(range)`: Return true if any of the range comparators intersect. -* `simplifyRange(versions, range)`: Return a "simplified" range that - matches the same items in the `versions` list as the range specified. Note - that it does *not* guarantee that it would match the same versions in all - cases, only for the set of versions provided. This is useful when - generating ranges by joining together multiple versions with `||` - programmatically, to provide the user with something a bit more - ergonomic. If the provided range is shorter in string-length than the - generated range, then that is returned. -* `subset(subRange, superRange)`: Return `true` if the `subRange` range is - entirely contained by the `superRange` range. - -Note that, since ranges may be non-contiguous, a version might not be -greater than a range, less than a range, *or* satisfy a range! For -example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9` -until `2.0.0`, so version `1.2.10` would not be greater than the -range (because `2.0.1` satisfies, which is higher), nor less than the -range (since `1.2.8` satisfies, which is lower), and it also does not -satisfy the range. - -If you want to know if a version satisfies or does not satisfy a -range, use the `satisfies(version, range)` function. - -### Coercion - -* `coerce(version, options)`: Coerces a string to semver if possible - -This aims to provide a very forgiving translation of a non-semver string to -semver. It looks for the first digit in a string and consumes all -remaining characters which satisfy at least a partial semver (e.g., `1`, -`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer -versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All -surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes -`3.4.0`). Only text which lacks digits will fail coercion (`version one` -is not valid). The maximum length for any semver component considered for -coercion is 16 characters; longer components will be ignored -(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any -semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value -components are invalid (`9999999999999999.4.7.4` is likely invalid). - -If the `options.rtl` flag is set, then `coerce` will return the right-most -coercible tuple that does not share an ending index with a longer coercible -tuple. For example, `1.2.3.4` will return `2.3.4` in rtl mode, not -`4.0.0`. `1.2.3/4` will return `4.0.0`, because the `4` is not a part of -any other overlapping SemVer tuple. - -If the `options.includePrerelease` flag is set, then the `coerce` result will contain -prerelease and build parts of a version. For example, `1.2.3.4-rc.1+rev.2` -will preserve prerelease `rc.1` and build `rev.2` in the result. - -### Clean - -* `clean(version)`: Clean a string to be a valid semver if possible - -This will return a cleaned and trimmed semver version. If the provided -version is not valid a null will be returned. This does not work for -ranges. - -ex. -* `s.clean(' = v 2.1.5foo')`: `null` -* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'` -* `s.clean(' = v 2.1.5-foo')`: `null` -* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'` -* `s.clean('=v2.1.5')`: `'2.1.5'` -* `s.clean(' =v2.1.5')`: `'2.1.5'` -* `s.clean(' 2.1.5 ')`: `'2.1.5'` -* `s.clean('~1.0.0')`: `null` - -## Constants - -As a convenience, helper constants are exported to provide information about what `node-semver` supports: - -### `RELEASE_TYPES` - -- major -- premajor -- minor -- preminor -- patch -- prepatch -- prerelease - -``` -const semver = require('semver'); - -if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) { - console.log('This is a valid release type!'); -} else { - console.warn('This is NOT a valid release type!'); -} -``` - -### `SEMVER_SPEC_VERSION` - -2.0.0 - -``` -const semver = require('semver'); - -console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION); -``` - -## Exported Modules - - - -You may pull in just the part of this semver utility that you need if you -are sensitive to packing and tree-shaking concerns.

The set -of primitive `operators` is: - -* `<` Less than -* `<=` Less than or equal to -* `>` Greater than -* `>=` Greater than or equal to -* `=` Equal. If no operator is specified, then equality is assumed, - so this operator is optional but MAY be included. - -For example, the comparator `>=1.2.7` would match the versions -`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6` -or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and -would match the versions `2.0.0` and `3.1.0`, but not the versions -`1.0.1` or `1.1.0`. - -Comparators can be joined by whitespace to form a `comparator set`, -which is satisfied by the **intersection** of all of the comparators -it includes. - -A range is composed of one or more comparator sets, joined by `||`. A -version matches a range if and only if every comparator in at least -one of the `||`-separated comparator sets is satisfied by the version. - -For example, the range `>=1.2.7 <1.3.0` would match the versions -`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`, -or `1.1.0`. - -The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`, -`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`. - -### Prerelease Tags - -If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then -it will only be allowed to satisfy comparator sets if at least one -comparator with the same `[major, minor, patch]` tuple also has a -prerelease tag. - -For example, the range `>1.2.3-alpha.3` would be allowed to match the -version `1.2.3-alpha.7`, but it would *not* be satisfied by -`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater -than" `1.2.3-alpha.3` according to the SemVer sort rules. The version -range only accepts prerelease tags on the `1.2.3` version. -Version `3.4.5` *would* satisfy the range because it does not have a -prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`. - -The purpose of this behavior is twofold. First, prerelease versions -frequently are updated very quickly, and contain many breaking changes -that are (by the author's design) not yet fit for public consumption. -Therefore, by default, they are excluded from range-matching -semantics. - -Second, a user who has opted into using a prerelease version has -indicated the intent to use *that specific* set of -alpha/beta/rc versions. By including a prerelease tag in the range, -the user is indicating that they are aware of the risk. However, it -is still not appropriate to assume that they have opted into taking a -similar risk on the *next* set of prerelease versions. - -Note that this behavior can be suppressed (treating all prerelease -versions as if they were normal versions, for range-matching) -by setting the `includePrerelease` flag on the options -object to any -[functions](https://github.com/npm/node-semver#functions) that do -range matching. - -#### Prerelease Identifiers - -The method `.inc` takes an additional `identifier` string argument that -will append the value of the string as a prerelease identifier: - -```javascript -semver.inc('1.2.3', 'prerelease', 'beta') -// '1.2.4-beta.0' -``` - -command-line example: - -```bash -$ semver 1.2.3 -i prerelease --preid beta -1.2.4-beta.0 -``` - -Which then can be used to increment further: - -```bash -$ semver 1.2.4-beta.0 -i prerelease -1.2.4-beta.1 -``` - -To get out of the prerelease phase, use the `release` option: - -```bash -$ semver 1.2.4-beta.1 -i release -1.2.4 -``` - -#### Prerelease Identifier Base - -The method `.inc` takes an optional parameter 'identifierBase' string -that will let you let your prerelease number as zero-based or one-based. -Set to `false` to omit the prerelease number altogether. -If you do not specify this parameter, it will default to zero-based. - -```javascript -semver.inc('1.2.3', 'prerelease', 'beta', '1') -// '1.2.4-beta.1' -``` - -```javascript -semver.inc('1.2.3', 'prerelease', 'beta', false) -// '1.2.4-beta' -``` - -command-line example: - -```bash -$ semver 1.2.3 -i prerelease --preid beta -n 1 -1.2.4-beta.1 -``` - -```bash -$ semver 1.2.3 -i prerelease --preid beta -n false -1.2.4-beta -``` - -### Advanced Range Syntax - -Advanced range syntax desugars to primitive comparators in -deterministic ways. - -Advanced ranges may be combined in the same way as primitive -comparators using white space or `||`. - -#### Hyphen Ranges `X.Y.Z - A.B.C` - -Specifies an inclusive set. - -* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4` - -If a partial version is provided as the first version in the inclusive -range, then the missing pieces are replaced with zeroes. - -* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4` - -If a partial version is provided as the second version in the -inclusive range, then all versions that start with the supplied parts -of the tuple are accepted, but nothing that would be greater than the -provided tuple parts. - -* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0` -* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0` - -#### X-Ranges `1.2.x` `1.X` `1.2.*` `*` - -Any of `X`, `x`, or `*` may be used to "stand in" for one of the -numeric values in the `[major, minor, patch]` tuple. - -* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless - `includePrerelease` is specified, in which case any version at all - satisfies) -* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version) -* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions) - -A partial version range is treated as an X-Range, so the special -character is in fact optional. - -* `""` (empty string) := `*` := `>=0.0.0` -* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0` -* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0` - -#### Tilde Ranges `~1.2.3` `~1.2` `~1` - -Allows patch-level changes if a minor version is specified on the -comparator.

You already know how to - compare strings. -* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`. -* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call - the corresponding function above. `"==="` and `"!=="` do simple - string comparison, but are included for completeness. Throws if an - invalid comparison string is provided. -* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if - `v2` is greater. Sorts in ascending order if passed to `Array.sort()`. -* `rcompare(v1, v2)`: The reverse of `compare`. Sorts an array of versions - in descending order when passed to `Array.sort()`. -* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions - are equal. Sorts in ascending order if passed to `Array.sort()`. -* `compareLoose(v1, v2)`: Short for `compare(v1, v2, { loose: true })`. -* `diff(v1, v2)`: Returns the difference between two versions by the release type - (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`), - or null if the versions are the same. - -### Sorting - -* `sort(versions)`: Returns a sorted array of versions based on the `compareBuild` - function. -* `rsort(versions)`: The reverse of `sort`. Returns an array of versions based on - the `compareBuild` function in descending order. - -### Comparators - -* `intersects(comparator)`: Return true if the comparators intersect - -### Ranges - -* `validRange(range)`: Return the valid range or null if it's not valid. -* `satisfies(version, range)`: Return true if the version satisfies the - range. -* `maxSatisfying(versions, range)`: Return the highest version in the list - that satisfies the range, or `null` if none of them do. -* `minSatisfying(versions, range)`: Return the lowest version in the list - that satisfies the range, or `null` if none of them do. -* `minVersion(range)`: Return the lowest version that can match - the given range. -* `gtr(version, range)`: Return `true` if the version is greater than all the - versions possible in the range. -* `ltr(version, range)`: Return `true` if the version is less than all the - versions possible in the range. -* `outside(version, range, hilo)`: Return true if the version is outside - the bounds of the range in either the high or low direction. The - `hilo` argument must be either the string `'>'` or `'<'`. (This is - the function called by `gtr` and `ltr`.) -* `intersects(range)`: Return true if any of the range comparators intersect. -* `simplifyRange(versions, range)`: Return a "simplified" range that - matches the same items in the `versions` list as the range specified. Note - that it does *not* guarantee that it would match the same versions in all - cases, only for the set of versions provided. This is useful when - generating ranges by joining together multiple versions with `||` - programmatically, to provide the user with something a bit more - ergonomic. If the provided range is shorter in string-length than the - generated range, then that is returned. -* `subset(subRange, superRange)`: Return `true` if the `subRange` range is - entirely contained by the `superRange` range. - -Note that, since ranges may be non-contiguous, a version might not be -greater than a range, less than a range, *or* satisfy a range! For -example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9` -until `2.0.0`, so version `1.2.10` would not be greater than the -range (because `2.0.1` satisfies, which is higher), nor less than the -range (since `1.2.8` satisfies, which is lower), and it also does not -satisfy the range. - -If you want to know if a version satisfies or does not satisfy a -range, use the `satisfies(version, range)` function. - -### Coercion - -* `coerce(version, options)`: Coerces a string to semver if possible - -This aims to provide a very forgiving translation of a non-semver string to -semver. It looks for the first digit in a string and consumes all -remaining characters which satisfy at least a partial semver (e.g., `1`, -`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer -versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All -surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes -`3.4.0`). Only text which lacks digits will fail coercion (`version one` -is not valid). The maximum length for any semver component considered for -coercion is 16 characters; longer components will be ignored -(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any -semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value -components are invalid (`9999999999999999.4.7.4` is likely invalid). - -If the `options.rtl` flag is set, then `coerce` will return the right-most -coercible tuple that does not share an ending index with a longer coercible -tuple. For example, `1.2.3.4` will return `2.3.4` in rtl mode, not -`4.0.0`. `1.2.3/4` will return `4.0.0`, because the `4` is not a part of -any other overlapping SemVer tuple. - -If the `options.includePrerelease` flag is set, then the `coerce` result will contain -prerelease and build parts of a version. For example, `1.2.3.4-rc.1+rev.2` -will preserve prerelease `rc.1` and build `rev.2` in the result. - -### Clean - -* `clean(version)`: Clean a string to be a valid semver if possible - -This will return a cleaned and trimmed semver version. If the provided -version is not valid a null will be returned. This does not work for -ranges. - -ex. -* `s.clean(' = v 2.1.5foo')`: `null` -* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'` -* `s.clean(' = v 2.1.5-foo')`: `null` -* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'` -* `s.clean('=v2.1.5')`: `'2.1.5'` -* `s.clean(' =v2.1.5')`: `'2.1.5'` -* `s.clean(' 2.1.5 ')`: `'2.1.5'` -* `s.clean('~1.0.0')`: `null` - -## Constants - -As a convenience, helper constants are exported to provide information about what `node-semver` supports: - -### `RELEASE_TYPES` - -- major -- premajor -- minor -- preminor -- patch -- prepatch -- prerelease - -``` -const semver = require('semver'); - -if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) { - console.log('This is a valid release type!'); -} else { - console.warn('This is NOT a valid release type!'); -} -``` - -### `SEMVER_SPEC_VERSION` - -2.0.0 - -``` -const semver = require('semver'); - -console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION); -``` - -## Exported Modules - - - -You may pull in just the part of this semver utility that you need if you -are sensitive to packing and tree-shaking concerns.

Returns either a -plain object, a string or `undefined`, or throws `YAMLException` on error. By default, does -not support regexps, functions and undefined. This method is safe for untrusted data. - -options: - -- `filename` _(default: null)_ - string to be used as a file path in - error/warning messages. -- `onWarning` _(default: null)_ - function to call on warning messages. - Loader will call this function with an instance of `YAMLException` for each warning. -- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ - specifies a schema to use. - - `FAILSAFE_SCHEMA` - only strings, arrays and plain objects: - http://www.yaml.org/spec/1.2/spec.html#id2802346 - - `JSON_SCHEMA` - all JSON-supported types: - http://www.yaml.org/spec/1.2/spec.html#id2803231 - - `CORE_SCHEMA` - same as `JSON_SCHEMA`: - http://www.yaml.org/spec/1.2/spec.html#id2804923 - - `DEFAULT_SAFE_SCHEMA` - all supported YAML types, without unsafe ones - (`!!js/undefined`, `!!js/regexp` and `!!js/function`): - http://yaml.org/type/ - - `DEFAULT_FULL_SCHEMA` - all supported YAML types. -- `json` _(default: false)_ - compatibility with JSON.parse behaviour.

It allows binary notation for integers. - - -### load (string [ , options ]) - -**Use with care with untrusted sources**. The same as `safeLoad()` but uses -`DEFAULT_FULL_SCHEMA` by default - adds some JavaScript-specific types: -`!!js/function`, `!!js/regexp` and `!!js/undefined`. For untrusted sources, you -must additionally validate object structure to avoid injections: - -``` javascript -const untrusted_code = '"toString": !

Uses `DEFAULT_SAFE_SCHEMA`, so it will -throw an exception if you try to dump regexps or functions. However, you can -disable exceptions by setting the `skipInvalid` option to `true`. - -options: - -- `indent` _(default: 2)_ - indentation width to use (in spaces). -- `noArrayIndent` _(default: false)_ - when true, will not add an indentation level to array elements -- `skipInvalid` _(default: false)_ - do not throw on invalid types (like function - in the safe schema) and skip pairs and single values with such types. -- `flowLevel` (default: -1) - specifies level of nesting, when to switch from - block to flow style for collections. -1 means block style everwhere -- `styles` - "tag" => "style" map. Each tag may have own set of styles. -- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ specifies a schema to use. -- `sortKeys` _(default: `false`)_ - if `true`, sort keys when dumping YAML. If a - function, use the function to sort the keys. -- `lineWidth` _(default: `80`)_ - set max line width. -- `noRefs` _(default: `false`)_ - if `true`, don't convert duplicate objects into references -- `noCompatMode` _(default: `false`)_ - if `true` don't try to be compatible with older - yaml versions. Currently: don't quote "yes", "no" and so on, as required for YAML 1.1 -- `condenseFlow` _(default: `false`)_ - if `true` flow sequences will be condensed, omitting the space between `a, b`. Eg. `'[a,b]'`, and omitting the space between `key: value` and quoting the key. Eg. `'{"a":b}'` Can be useful when using yaml for pretty URL query params as spaces are %-encoded. - -The following table show availlable styles (e.g. "canonical", -"binary"...) available for each tag (.e.g. !!null, !!int ...).
