Any Mercurial extension to grep for newly checked in code (not having "console.log")?

Is there any Mercurial extension that can grep for "console.log" that might have been accidentally left over as debugging code?

Right now this is what I am doing:

1) hg out ssh://....  

the above is to see what is the first committed revision in my local repo, say, the smallest revis开发者_JAVA百科ion is 3456

2) hg diff -r 3455 | grep "^+" | grep "console\.log"

The number 3455 is 3456 - 1. the first grep is to see newly added code. the second one is for console.log

This method can tell that I have "console.log" in the new code, but won't say what file it is in.

It sounds like you're in need of a commit hook. Try putting something like this into your .hg/hgrc (or ~/.hgrc if you want it global):

[hooks]
pretxncommit = sh -c 'if hg log -p -r $HG_NODE | grep -q '^\+.*console\.log' ; then exit 1; else exit 0; fi'

That will abort your commits if they would be adding a line that contains console.log. Your commit message will be saved in .hg/last-message.txt.
