[pypy-dev] Problems with parsing

[Leonardo Santagada]

I'm having 2 problems with parsing js files, so i'm sending this  
email in a call for help:

1) My string regex is not working the one i'm using now:

stringliteral   : <SINGLESTRING>
                 | <DOUBLESTRING>
                 ;

SINGLESTRING    : "'([^']|\\')*'"
                 ;

DOUBLESTRING    : "\"([^\"]|\\\")*\""
                 ;

don't work with this valid js string: "\'\"\\"

2) The parsing module is reaching recursion limit on /pypy/lang/js/ 
test/ecma/FunctionObjects/15.3.1.1-3.js if you uncomment the code. I  
get the idea of where the problem lies, we have there a function with  
2k params, but still, it works on spidermonkey and I think I should  
support this. you can test this by going to the dir and type "py.test  
--ecna 15.3.1.1-3.js" to see what happens.


thanks in advance,
