There are several ways to run +such a walker. + +**simple**`(node, visitors, base, state)` does a 'simple' walk over a +tree. `node` should be the AST node to walk, and `visitors` an object +with properties whose names correspond to node types in the [ESTree +spec](https://github.com/estree/estree). The properties should contain +functions that will be called with the node object and, if applicable +the state at that point. The last two arguments are optional. `base` +is a walker algorithm, and `state` is a start state. The default +walker will simply visit all statements and expressions and not +produce a meaningful state. (An example of a use of state is to track +scope at each point in the tree.) + +```js +const acorn = require("acorn") +const walk = require("acorn-walk") + +walk.simple(acorn.parse("let x = 10"), { + Literal(node) { + console.log(`Found a literal: ${node.value}`) + } +}) +``` + +**ancestor**`(node, visitors, base, state)` does a 'simple' walk over +a tree, building up an array of ancestor nodes (including the current node) +and passing the array to the callbacks as a third parameter. + +```js +const acorn = require("acorn") +const walk = require("acorn-walk") + +walk.ancestor(acorn.parse("foo('hi')"), { + Literal(_, ancestors) { + console.log("This literal's ancestors are:", ancestors.map(n => n.type)) + } +}) +``` + +**recursive**`(node, state, functions, base)` does a 'recursive' +walk, where the walker functions are responsible for continuing the +walk on the child nodes of their target node. `state` is the start +state, and `functions` should contain an object that maps node types +to walker functions. Such functions are called with `(node, state, c)` +arguments, and can cause the walk to continue on a sub-node by calling +the `c` argument on it with `(node, state)` arguments. The optional +`base` argument provides the fallback walker functions for node types +that aren't handled in the `functions` object. If not given, the +default walkers will be used. + +**make**`(functions, base)` builds a new walker object by using the +walker functions in `functions` and filling in the missing ones by +taking defaults from `base`. + +**full**`(node, callback, base, state)` does a 'full' walk over a +tree, calling the callback with the arguments (node, state, type) for +each node + +**fullAncestor**`(node, callback, base, state)` does a 'full' walk +over a tree, building up an array of ancestor nodes (including the +current node) and passing the array to the callbacks as a third +parameter. + +```js +const acorn = require("acorn") +const walk = require("acorn-walk") + +walk.full(acorn.parse("1 + 1"), node => { + console.log(`There's a ${node.type} node at ${node.ch}`) +}) +``` + +**findNodeAt**`(node, start, end, test, base, state)` tries to locate +a node in a tree at the given start and/or end offsets, which +satisfies the predicate `test`. `start` and `end` can be either `null` +(as wildcard) or a number. `test` may be a string (indicating a node +type) or a function that takes `(nodeType, node)` arguments and +returns a boolean indicating whether this node is interesting. `base` +and `state` are optional, and can be used to specify a custom walker. +Nodes are tested from inner to outer, so if two nodes match the +boundaries, the inner one will be preferred. + +**findNodeAround**`(node, pos, test, base, state)` is a lot like +`findNodeAt`, but will match any node that exists 'around' (spanning) +the given position. + +**findNodeAfter**`(node, pos, test, base, state)` is similar to +`findNodeAround`, but will match all nodes *after* the given position +(testing outer nodes before inner nodes). diff --git a/node_modules/acorn-walk/dist/walk.d.ts b/node_modules/acorn-walk/dist/walk.d.ts new file mode 100644 index 0000000..00cc005 --- /dev/null +++ b/node_modules/acorn-walk/dist/walk.d.ts @@ -0,0 +1,112 @@ +import {Node} from 'acorn'; + +declare module "acorn-walk" { + type FullWalkerCallback = ( + node: Node, + state: TState, + type: string + ) => void; + + type FullAncestorWalkerCallback = ( + node: Node, + state: TState | Node[], + ancestors: Node[], + type: string + ) => void; + type WalkerCallback = (node: Node, state: TState) => void; + + type SimpleWalkerFn = ( + node: Node, + state: TState + ) => void; + + type AncestorWalkerFn = ( + node: Node, + state: TState| Node[], + ancestors: Node[] + ) => void; + + type RecursiveWalkerFn = ( + node: Node, + state: TState, + callback: WalkerCallback + ) => void; + + type SimpleVisitors = { + [type: string]: SimpleWalkerFn + }; + + type AncestorVisitors = { + [type: string]: AncestorWalkerFn + }; + + type RecursiveVisitors = { + [type: string]: RecursiveWalkerFn + }; + + type FindPredicate = (type: string, node: Node) => boolean; + + interface Found { + node: Node, + state: TState + } + + export function simple( + node: Node, + visitors: SimpleVisitors, + base?: RecursiveVisitors, + state?: TState + ): void; + + export function ancestor( + node: Node, + visitors: AncestorVisitors, + base?: RecursiveVisitors, + state?: TState + ): void; + + export function recursive( + node: Node, + state: TState, + functions: RecursiveVisitors, + base?: RecursiveVisitors + ): void; + + export function full( + node: Node, + callback: FullWalkerCallback, + base?: RecursiveVisitors, + state?: TState + ): void; + + export function fullAncestor( + node: Node, + callback: FullAncestorWalkerCallback, + base?: RecursiveVisitors, + state?: TState + ): void; + + export function make( + functions: RecursiveVisitors, + base?: RecursiveVisitors + ): RecursiveVisitors; + + export function findNodeAt( + node: Node, + start: number | undefined, + end?: number | undefined, + type?: FindPredicate | string, + base?: RecursiveVisitors, + state?: TState + ): Found | undefined; + + export function findNodeAround( + node: Node, + start: number | undefined, + type?: FindPredicate | string, + base?: RecursiveVisitors, + state?: TState + ): Found | undefined; + + export const findNodeAfter: typeof findNodeAround; +} diff --git a/node_modules/acorn-walk/dist/walk.js b/node_modules/acorn-walk/dist/walk.js new file mode 100644 index 0000000..17da67c --- /dev/null +++ b/node_modules/acorn-walk/dist/walk.js @@ -0,0 +1,463 @@ +(function (global, factory) { + typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports) : + typeof define === 'function' && define.amd ? define(['exports'], factory) : + (global = global || self, factory((global.acorn = global.acorn || {}, global.acorn.walk = {}))); +}(this, (function (exports) { 'use strict'; + + // AST walker module for Mozilla Parser API compatible trees + + // A simple walk is one where you simply specify callbacks to be + // called on specific nodes.

fixes + +Fix spurious duplicate variable definition errors for named functions. + +## 5.0.2 (2017-03-30) + +### Bug fixes + +A binary operator after a parenthesized arrow expression is no longer incorrectly treated as an error. + +## 5.0.0 (2017-03-28) + +### Bug fixes + +Raise an error for duplicated lexical bindings. + +Fix spurious error when an assignement expression occurred after a spread expression. + +Accept regular expressions after `of` (in `for`/`of`), `yield` (in a generator), and braced arrow functions. + +Allow labels in front or `var` declarations, even in strict mode. + +### Breaking changes + +Parse declarations following `export default` as declaration nodes, not expressions. This means that class and function declarations nodes can now have `null` as their `id`. + +## 4.0.11 (2017-02-07) + +### Bug fixes + +Allow all forms of member expressions to be parenthesized as lvalue. + +## 4.0.10 (2017-02-07) + +### Bug fixes + +Don't expect semicolons after default-exported functions or classes, even when they are expressions. + +Check for use of `'use strict'` directives in non-simple parameter functions, even when already in strict mode. + +## 4.0.9 (2017-02-06) + +### Bug fixes + +Fix incorrect error raised for parenthesized simple assignment targets, so that `(x) = 1` parses again. + +## 4.0.8 (2017-02-03) + +### Bug fixes + +Solve spurious parenthesized pattern errors by temporarily erring on the side of accepting programs that our delayed errors don't handle correctly yet. + +## 4.0.7 (2017-02-02) + +### Bug fixes + +Accept invalidly rejected code like `(x).y = 2` again. + +Don't raise an error when a function _inside_ strict code has a non-simple parameter list. + +## 4.0.6 (2017-02-02) + +### Bug fixes + +Fix exponential behavior (manifesting itself as a complete hang for even relatively small source files) introduced by the new 'use strict' check. + +## 4.0.5 (2017-02-02) + +### Bug fixes + +Disallow parenthesized pattern expressions. + +Allow keywords as export names. + +Don't allow the `async` keyword to be parenthesized. + +Properly raise an error when a keyword contains a character escape. + +Allow `"use strict"` to appear after other string literal expressions. + +Disallow labeled declarations. + +## 4.0.4 (2016-12-19) + +### Bug fixes + +Fix crash when `export` was followed by a keyword that can't be +exported. + +## 4.0.3 (2016-08-16) + +### Bug fixes + +Allow regular function declarations inside single-statement `if` branches in loose mode. Forbid them entirely in strict mode. + +Properly parse properties named `async` in ES2017 mode. + +Fix bug where reserved words were broken in ES2017 mode. + +## 4.0.2 (2016-08-11) + +### Bug fixes + +Don't ignore period or 'e' characters after octal numbers. + +Fix broken parsing for call expressions in default parameter values of arrow functions. + +## 4.0.1 (2016-08-08) + +### Bug fixes + +Fix false positives in duplicated export name errors. + +## 4.0.0 (2016-08-07) + +### Breaking changes + +The default `ecmaVersion` option value is now 7. + +A number of internal method signatures changed, so plugins might need to be updated. + +### Bug fixes + +The parser now raises errors on duplicated export names. + +`arguments` and `eval` can now be used in shorthand properties. + +Duplicate parameter names in non-simple argument lists now always produce an error. + +### New features + +The `ecmaVersion` option now also accepts year-style version numbers +(2015, etc). + +Support for `async`/`await` syntax when `ecmaVersion` is >= 8. + +Support for trailing commas in call expressions when `ecmaVersion` is >= 8. + +## 3.3.0 (2016-07-25) + +### Bug fixes + +Fix bug in tokenizing of regexp operator after a function declaration. + +Fix parser crash when parsing an array pattern with a hole. + +### New features + +Implement check against complex argument lists in functions that enable strict mode in ES7. + +## 3.2.0 (2016-06-07) + +### Bug fixes + +Improve handling of lack of unicode regexp support in host +environment. + +Properly reject shorthand properties whose name is a keyword. + +### New features + +Visitors created with `visit.make` now have their base as _prototype_, rather than copying properties into a fresh object. + +## 3.1.0 (2016-04-18) + +### Bug fixes + +Properly tokenize the division operator directly after a function expression. + +Allow trailing comma in destructuring arrays. + +## 3.0.4 (2016-02-25) + +### Fixes + +Allow update expressions as left-hand-side of the ES7 exponential operator. + +## 3.0.2 (2016-02-10) + +### Fixes + +Fix bug that accidentally made `undefined` a reserved word when parsing ES7. + +## 3.0.0 (2016-02-10) + +### Breaking changes + +The default value of the `ecmaVersion` option is now 6 (used to be 5). + +Support for comprehension syntax (which was dropped from the draft spec) has been removed. + +### Fixes + +`let` and `yield` are now “contextual keywords”, meaning you can mostly use them as identifiers in ES5 non-strict code. + +A parenthesized class or function expression after `export default` is now parsed correctly. + +### New features + +When `ecmaVersion` is set to 7, Acorn will parse the exponentiation operator (`**`). + +The identifier character ranges are now based on Unicode 8.0.0. + +Plugins can now override the `raiseRecoverable` method to override the way non-critical errors are handled. + +## 2.7.0 (2016-01-04) + +### Fixes + +Stop allowing rest parameters in setters. + +Disallow `y` rexexp flag in ES5. + +Disallow `\00` and `\000` escapes in strict mode. + +Raise an error when an import name is a reserved word. + +## 2.6.2 (2015-11-10) + +### Fixes + +Don't crash when no options object is passed. + +## 2.6.0 (2015-11-09) + +### Fixes + +Add `await` as a reserved word in module sources. + +Disallow `yield` in a parameter default value for a generator. + +Forbid using a comma after a rest pattern in an array destructuring. + +### New features + +Support parsing stdin in command-line tool. + +## 2.5.0 (2015-10-27) + +### Fixes + +Fix tokenizer support in the command-line tool. + +Stop allowing `new.target` outside of functions. + +Remove legacy `guard` and `guardedHandler` properties from try nodes. + +Stop allowing multiple `__proto__` properties on an object literal in strict mode. + +Don't allow rest parameters to be non-identifier patterns. + +Check for duplicate paramter names in arrow functions. diff --git a/node_modules/acorn/LICENSE b/node_modules/acorn/LICENSE new file mode 100644 index 0000000..cc5272c --- /dev/null +++ b/node_modules/acorn/LICENSE @@ -0,0 +1,21 @@ +MIT License + +Copyright (C) 2012-2018 by various contributors (see AUTHORS) + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

For questions +and discussion, please use the +[Tern discussion forum](https://discuss.ternjs.net). + +## Installation + +The easiest way to install acorn is from [`npm`](https://www.npmjs.com/): + +```sh +npm install acorn +``` + +Alternately, you can download the source and build acorn yourself: + +```sh +git clone https://github.com/acornjs/acorn.git +cd acorn +npm install +``` + +## Interface + +**parse**`(input, options)` is the main interface to the library. The +`input` parameter is a string, `options` can be undefined or an object +setting some of the options listed below. The return value will be an +abstract syntax tree object as specified by the [ESTree +spec](https://github.com/estree/estree). + +```javascript +let acorn = require("acorn"); +console.log(acorn.parse("1 + 1")); +``` + +When encountering a syntax error, the parser will raise a +`SyntaxError` object with a meaningful message. The error object will +have a `pos` property that indicates the string offset at which the +error occurred, and a `loc` object that contains a `{line, column}` +object referring to that same position. + +Options can be provided by passing a second argument, which should be +an object containing any of these fields: + +- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be + either 3, 5, 6 (2015), 7 (2016), 8 (2017), 9 (2018), 10 (2019) or 11 + (2020, partial support). This influences support for strict mode, + the set of reserved words, and support for new syntax features. + Default is 10. + + **NOTE**: Only 'stage 4' (finalized) ECMAScript features are being + implemented by Acorn. Other proposed new features can be implemented + through plugins. + +- **sourceType**: Indicate the mode the code should be parsed in. Can be + either `"script"` or `"module"`. This influences global strict mode + and parsing of `import` and `export` declarations. + + **NOTE**: If set to `"module"`, then static `import` / `export` syntax + will be valid, even if `ecmaVersion` is less than 6. + +- **onInsertedSemicolon**: If given a callback, that callback will be + called whenever a missing semicolon is inserted by the parser. The + callback will be given the character offset of the point where the + semicolon is inserted as argument, and if `locations` is on, also a + `{line, column}` object representing this position. + +- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing + commas. + +- **allowReserved**: If `false`, using a reserved word will generate + an error. Defaults to `true` for `ecmaVersion` 3, `false` for higher + versions. When given the value `"never"`, reserved words and + keywords can also not be used as property names (as in Internet + Explorer's old parser). + +- **allowReturnOutsideFunction**: By default, a return statement at + the top level raises an error. Set this to `true` to accept such + code. + +- **allowImportExportEverywhere**: By default, `import` and `export` + declarations can only appear at a program's top level. Setting this + option to `true` allows them anywhere where a statement is allowed. + +- **allowAwaitOutsideFunction**: By default, `await` expressions can + only appear inside `async` functions. Setting this option to + `true` allows to have top-level `await` expressions. They are + still not allowed in non-`async` functions, though. + +- **allowHashBang**: When this is enabled (off by default), if the + code starts with the characters `#!` (as in a shellscript), the + first line will be treated as a comment. + +- **locations**: When `true`, each node has a `loc` object attached + with `start` and `end` subobjects, each of which contains the + one-based line and zero-based column numbers in `{line, column}` + form. Default is `false`. + +- **onToken**: If a function is passed for this option, each found + token will be passed in same format as tokens returned from + `tokenizer().getToken()`. + + If array is passed, each found token is pushed to it. + + Note that you are not allowed to call the parser from the + callback—that will corrupt its internal state. + +- **onComment**: If a function is passed for this option, whenever a + comment is encountered the function will be called with the + following parameters: + + - `block`: `true` if the comment is a block comment, false if it + is a line comment. + - `text`: The content of the comment. + - `start`: Character offset of the start of the comment. + - `end`: Character offset of the end of the comment. + + When the `locations` options is on, the `{line, column}` locations + of the comment’s start and end are passed as two additional + parameters. + + If array is passed for this option, each found comment is pushed + to it as object in Esprima format: + + ```javascript + { + "type": "Line" | "Block", + "value": "comment text", + "start": Number, + "end": Number, + // If `locations` option is on: + "loc": { + "start": {line: Number, column: Number} + "end": {line: Number, column: Number} + }, + // If `ranges` option is on: + "range": [Number, Number] + } + ``` + + Note that you are not allowed to call the parser from the + callback—that will corrupt its internal state. + +- **ranges**: Nodes have their start and end characters offsets + recorded in `start` and `end` properties (directly on the node, + rather than the `loc` object, which holds line/column data. To also + add a + [semi-standardized](https://bugzilla.mozilla.org/show_bug.cgi?id=745678) + `range` property holding a `[start, end]` array with the same + numbers, set the `ranges` option to `true`. + +- **program**: It is possible to parse multiple files into a single + AST by passing the tree produced by parsing the first file as the + `program` option in subsequent parses. This will add the toplevel + forms of the parsed file to the "Program" (top) node of an existing + parse tree. + +- **sourceFile**: When the `locations` option is `true`, you can pass + this option to add a `source` attribute in every node’s `loc` + object. Note that the contents of this option are not examined or + processed in any way; you are free to use whatever format you + choose. + +- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property + will be added (regardless of the `location` option) directly to the + nodes, rather than the `loc` object. + +- **preserveParens**: If this option is `true`, parenthesized expressions + are represented by (non-standard) `ParenthesizedExpression` nodes + that have a single `expression` property containing the expression + inside parentheses. + +**parseExpressionAt**`(input, offset, options)` will parse a single +expression in a string, and return its AST. It will not complain if +there is more of the string left after the expression. + +**tokenizer**`(input, options)` returns an object with a `getToken` +method that can be called repeatedly to get the next token, a `{start, +end, type, value}` object (with added `loc` property when the +`locations` option is enabled and `range` property when the `ranges` +option is enabled). When the token's type is `tokTypes.eof`, you +should stop calling the method, since it will keep returning that same +token forever. + +In ES6 environment, returned result can be used as any other +protocol-compliant iterable: + +```javascript +for (let token of acorn.tokenizer(str)) { + // iterate over the tokens +} + +// transform code to array of tokens: +var tokens = [...acorn.tokenizer(str)]; +``` + +**tokTypes** holds an object mapping names to the token type objects +that end up in the `type` properties of tokens. + +**getLineInfo**`(input, offset)` can be used to get a `{line, +column}` object for a given program string and offset. + +### The `Parser` class + +Instances of the **`Parser`** class contain all the state and logic +that drives a parse. It has static methods `parse`, +`parseExpressionAt`, and `tokenizer` that match the top-level +functions by the same name. + +When extending the parser with plugins, you need to call these methods +on the extended version of the class. To extend a parser with plugins, +you can use its static `extend` method. + +```javascript +var acorn = require("acorn"); +var jsx = require("acorn-jsx"); +var JSXParser = acorn.Parser.extend(jsx()); +JSXParser.parse("foo()"); +``` + +The `extend` method takes any number of plugin values, and returns a +new `Parser` class that includes the extra parser logic provided by +the plugins. + +## Command line interface + +The `bin/acorn` utility can be used to parse a file from the command +line. It accepts as arguments its input file and the following +options: + +- `--ecma3|--ecma5|--ecma6|--ecma7|--ecma8|--ecma9|--ecma10`: Sets the ECMAScript version + to parse. Default is version 9. + +- `--module`: Sets the parsing mode to `"module"`.
