Hello,

I want to know if there exists a tool to help in reversing a compressed javascript that has obscure variable names. I am not looking for a pretty-printing beautifier, but for a tool that actually know a to change & propagate variable name choices.

Let me be more specific : - some of the functions belong to the 'public' API and i want to impose readable argument names in their prototypes - there are intermediary variables for document, window and other browser idioms

I would like to give this knowledge to the tool and then let it create another javascript where the knowledge would have been correctly propagated.

thanks Jerome Wagner
