JSSGF

JSSGF is a parser for Smart Game Format(SGF) in JavaScript generated by Jison with faster regular expression parser in simple cases.

Usage

on browsers

<script type="text/javascript">
console.log(jssgf.fastParse('(;C[example])'));
</script> 

on Node.js

npm install jssgf

var jssgf = require('jssgf');
console.log(jssgf.fastParse('(;C[example])'));

Note

ValueType

No support of various ValueTypes and Compose. All PropValues are as Text.

Compilation

When you compile jssgf.jison, you will encounter the message

Conflict in grammar: multiple actions possible when lookahead token is [ in state 16
- reduce by rule: propvalues ->
- shift token (then go to state 23)
Conflict in grammar: multiple actions possible when lookahead token is WHITE_SPACE in state 17
- reduce by rule: propident -> MAYBE_PROPIDENT
- shift token (then go to state 24)
...

But jssgf.js should have been generated. Jison resolves the conflicts with higher priority to a shift.
