[webkit-dev] about parse javascript function

You can have a look at source file: JavaScriptCore/parser/Parser.cpp. Inside
this file, you will come across the function:

*parse**(JSGlobalData* globalData, int* errLine, UString* errMsg)
This function in turn invokes the routines of *Lexer.cpp* and *grammar.cpp*.
Lexer.cpp resides in JavaScriptCore/parser directory. However, grammar.cpp
is generated during build and in generally placed inside DerivedSources. The
parsing of JavaScript code is initiated by call to function: *jscyyparse**()
* that is available inside grammar.cpp. I hope this gives you a starting
point. (I am using WebKit revision: *41242*)
