jison2json


jison grammars come in two formats: JSON or a special text format similar to Bison's. This utility converts from the jison's format to JSON. See the json2jison for the reverse conversion.

install

npm install @gerhobbelt/jison2json -g

build

Follow the install & build directions of the monorepo.

You can also only build this particular subpackage by cd-ing into this directory
and then invoking the local make:

cd packages/jison2json
make

This will generate the rollup/babel-postprocessed ES6 and ES5
compatible libraries in the local dist/ directory.

usage

# single grammar
jison2json grammar.y

# or separate grammars
jison2json grammar.y lex.l

Or require it and convert programatically:

var jison2json = require('@gerhobbelt/jison2json');
var grammar = "%% foo: bar { return true; };";

var json = jison2json.convert(grammar);
