Emacs users: hg-tools-grep
Hark fellow Emacsers. All you unenlightened heathens can stop reading now. A few years ago, my colleague Jono Lange wrote probably the best little chunk of Emacs lisp ever. `M-x bzr-tools-grep` lets you easily search a Bazaar repository for a case-sensitive string, providing you with a nice *grep* buffer which you can scroll through. When you find a code sample you want to look at, C-c C-c visits the file and plops you right at the matching line. You *only* grep through files under version control, so you get to ignore generated files, and compilation artifacts, etc. Of course, this doesn't help you for working on the Python code base, because Mercurial. I finally whipped up this straight up rip of Jono's code to work with hg. I'm actually embarrassed to put a copyright on this thing, and would happily just donate it to Jono, drop it in Python's Misc directory, or slip it like a lump of coal into the xmas stocking of whoever wants to "maintain" it for the next 20 years. But anyway, it's already proven enormously helpful to me, so here it is. Cheers, -Barry P.S.

Thanks, I'll definitely use this! Georg

Oh, I do! I also feel weird about adding a copyright to this, but how will other people feel comfortable using it if I don't?

Nice! I've been told that Emacs 23 is probably a minimum requirement because locate-dominating-file is missing in <= Emacs 22. I'm using Emacs 24.2 almost everywhere these days. -Barry

What's wrong with git grep?
Or "hg grep", for that matter? -- Ross Lagerwall

hg grep searches the history, not the working copy. *-tools-grep only searches the working copy but automatically filters files to only search in files under version control. Which as far as I know is indeed what git-grep does already.
Yes indeed-- in my eagerness to make my first post to python-dev be well-received I completely forgot about git grep. brandon On Wed, Dec 12, 2012 at 9:20 AM, Xavier Morel <python-dev@masklinn.net>wrote:

hg grep searches in the repository history, so it's not good for this.
