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.
From today (2017/oct/15) the jison2json repository is obsolete for the
jison2jsonpackage/codebase: the primary source is the jison monorepo'spackages/jison2json/directory. See also GerHobbelt/jison#16.(For a comparable argument, see also "Why is Babel a monorepo?")
Issues, pull requests, etc. for
jison2jsonshould be filed there; hence we do not accept issue reports in this secondary repository any more.This repository will track the primary source for a while still, but be very aware that this particular repository will always be lagging behind!
npm install @gerhobbelt/jison2json -g
To build the library yourself, follow the install & build directions of the monorepo.
# 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);
