问题
I want to make a python program that uses PLY to parse Javascript files, I din't found any sources of parsers that implement the ECMAScript, Javascript rules that use PLY.
The only thing I found was some ANTLR grammar files to parse javascript and ecmascript: http://www.antlr.org/grammar/1153976512034/ecmascriptA3.g http://www.antlr.org/grammar/1206736738015/JavaScript.g
Can ANTLR grammar files be adapted to be used as PLY rules, if yes, how can be done in a semi-automatic way, do I need to parse the grammar files? Is there another workaround this (i.e. than using ANTLR grammar files)?

No, they can't. PLY generates LALR parsers while ANTLR generates LL ones. Their input grammars are too different for a trivial (or automated) conversion.
