Directory comparison of Git branches
3 answers
Is it possible to get the git difftool command to open a directory compare between the changed files and the staging/checked files?
So ideally, if 2 files have changed, they would be the only 2 shown, but within a directory compare.
I've read posts about getting git to give all file diffs in parallel, so tools like BeyondCompare has all the diffs in tabs, but im not happy with that!
One could pull a copy of the changed files from staging/checked in files into a temp folder, and then open that up. Is that the only option?
Update June 2012 (2 and an half years later):
This (comparing directories instead of file-by-file) seems to be soon available:
See [ANNOUNCE] Git 1.7.11.rc1:
"git difftool
" learned the "--dir-diff
" option to spawn external diff tools that can compare two directory hierarchies at a time after populating two temporary directories, instead of running an instance of the external tool once per a file pair.
See "Patch difftool
: teach difftool
to handle directory diffs"

Basically yes:
You difftool script would:
- create 2 temp directories
- defines itself as a diff tool
- call git diff
- which then call itself for file to diff
- in that mode, the same script, for each files, only copy the two version to diff in the two temp directories
- then go on and call diff tools (like beyondCompare or WinMerge) on the two temp directories
You have one first example in this question.
I always use --dirstat=files
:
rudie@devver:virenze$ git diff --dirstat=files
4.1% modules/custom/virenze_conversations/
7.0% modules/custom/virenze_crs/
8.3% modules/custom/
which means I've removed dirs virenze_conversations
and virenze_crs
in custom
. (I don't know what the percentages mean...)
You can probably use all the normal diff
options: --cached
, branch name etc.
