[ragel-users] ANN: libejson, extended JSON parser library

[Adrian Thurston]

Does JSON have comments? Is that just Javascript comments?

When the machine gets huge because a particular complicated pattern 
appears all over, that's a good sign you need to use the traditional 
lexer + parser approach. Some people like to use ragel to parse directly 
though. Which you do is a matter of preference I suppose.
