babel-plugin-chevrotain-serialize

babel-plugin-serialize-chevrotain-parsers

This plugin finds class declarations which inherit from chevrotain.Parser, serializes them, and passes this serialization into their constructor super calls, allowing your code to bypass parser grammar construction at runtime. This is especially useful if you run your code through a minifier, as you’ll no longer have to avoid mangling token names.

Installation

npm install --save-dev babel-plugin-serialize-chevrotain-parsers

or

yarn add --dev babel-plugin-serialize-chevrotain-parsers

Usage

Add the plugin to your .babelrc.

{
  "plugins": ["babel-plugin-serialize-chevrotain-parsers"]
}

The plugin will find Parser references which are imported and referenced in one of four ways.

// method 1
import { Parser } from "chevrotain";
// method 2
const { Parser } = require("chevrotain");
// method 1 & 2 reference
class MyParser extends Parser {
}
// method 3
import * as chevrotain from "chevrotain";
// method 4
const chevrotain = require("chevrotain");
// method 3 & 4 reference
class MyParser extends chevrotain.Parser {
}
// will not work
const Parser1 = Parser;
// this will not be detected
class MyParser extends Parser1 {
}
