bnf-syntax.nvim

Simple syntax highlighting for BNF (Backus-Naur Form) grammar files in Neovim.

Demo

Installation

Lazy.nvim

{
  "adamkleo/bnf-syntax"
}

Packer

use "adamkleo/bnf-syntax"

Usage

The plugin automatically detects .bnf files and applies syntax highlighting. No configuration required.

Example BNF syntax that will be highlighted:

<expression> ::= <term> | <expression> "+" <term>
<term> ::= <factor> | <term> "*" <factor>
<factor> ::= "(" <expression> ")" | <number>

Configuration

Optionally customize the filetype and extension:

require("bnf-syntax").setup({
  filetype = "bnf",
  extension = "bnf"
})

The extension option is used to match files ending with the chosen extension. The filetype option sets the filetype of the matched files. By default, these values are both "bnf"
