Emacs tricks of the day: Replace in files; Diff & Merge

[ #23968 ]

In an earlier post I mentioned I didn't know how to search-n-replace in multiple files using Emacs.

It turns out there is no good way to do that out-of-the-box. But after an intense Google session I found this entry in the Emacs Wiki: GlobRep.

There are other options as well, mentioned on the SearchAndReplace page, but that page seems a bit chaotic, and I'm quite happy with GlobRep.

The other day I also discovered (well, discovered... I needed the functionality and looked for it) ediff, and especially ediff-directories. Very, very powerful diff and merge functionality, usable in a vague kind of way. In some way it's even better than Araxis Merge which is an accomplishment.

  • Ediff is one of the best reasons for staying in Emacs. I've been using Eclipse [] a lot recently and it's very, very good overall. But the diff utility just plain sucks after using ediff.

    For more info, look at the EdiffMode [] page on the emacs wiki. There's good tips there.
