Mercurial: Prevent commiting certain changes

I'm sure we've all done that thing where you temporarily hot-wire part of your application while you test something. We really don't want to commit such changes though.

Usually I mark such lines with a comment reminding me not to commit this change. But is there some way I can program Mercurial itself to refuse to commit any line containing a certain text fragment? (Not the entire file, just the marked line.) Is there some extension or something that does that?

Contrary to (good and correct in terms of sense) platetmaker's answer I'll suggest another way:

  • Enable, learn and use MQ Extension (see also Tutorial page) or, as lightweight alternative, Shelve Extension
  • Store your WIP (modifications in working directory) as MQ-patches or shelves locally until they aren't finished

The answer is a clear 'No, but...' (or 'Yes, but...' - depends on how you see it).

If you always indicate WIP lines in the same manner, I recommend to write and install a (local) commit hook which will fail, if any such WIP lines are detected in the changeset. See https://www.mercurial-scm.org/wiki/Hook and https://www.mercurial-scm.org/wiki/UsefulHooks

In order to commit only some hunks, you can make use of the record extension (it's a default extension, just needs enabling). It allows you to cherry-pick the hunks at commit time. But it will fail at cherry-picking if the WIP code and the 'actual' code are in the same hunk.
