jison-gho-loader

A loader for webpack which transforms .jison files into JS code.

Usage

Install the package using npm:

$ npm install jison-gho-loader --save-dev

Ad-hoc use

// RequireJS
const parser = require('jison-gho-loader!./grammar.jison').parser;

// import/export
import {parser} from 'jison-gho-loader!./grammar.jison';

const result = parser.parse(input_to_parse);

Webpack config

Your webpack.config.js should contain:

module.exports = {
    module: {
        rules: [
            {
                test: /\.jison$/,
                use: 'jison-gho-loader'
            }
        ]
    }
}

And then just import the grammar.jison without loader prefix:

// RequireJS
const parser = require('./grammar.jison').parser;

// import/export
import {parser} from './grammar.jison';

const result = parser.parse(input_to_parse);

Options

You can specify options that can be sent to the jison-gho like which parser type to use (lalr, ll, lr, etc). Example:

module.exports = {
    module: {
        rules: [
            {
                test: /\.jison$/,
                use: {
                    loader: 'jison-gho-loader',
                    options: { parserType: 'lr0' }
                }
            }
        ]
    }
}

All options can be found in the index.js file.
