Subject: Add filename to the JS_Parse_Error exception.
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=ae07714927f44790e40628cde4fa57bc2c4cb076;p=UglifyJS.git

Add filename to the JS_Parse_Error exception.

It would be nice to have access to the filename of the file that includes the code that causes a JavaScript error. This is especially handy if uglifying multiple files at once.

Only a small change is needed for this to happen as it's already available in the function that throws the error.
