The 'git difftool' allows the user to view diffs using an external tool. It runs a separate instance of the tool for each file in the diff. This makes it tedious to review changes spanning multiple files. The 'git-diffall' script instead prepares temporary directories with the files to be compared and launches a single instance of the external diff tool to view them (i.e. a directory diff). The 'diff.tool' or 'merge.tool' configuration variable is used to specify which external tool is used.

The git-diffall script provides a directory based diff mechanism
|
|
for git.
|
|
|
|
To determine what diff viewer is used, the script requires either
|
|
the 'diff.tool' or 'merge.tool' configuration option to be set.
|
|
|
|
This script is compatible with most common forms used to specify a
|
|
range of revisions to diff:
|
|
|
|
1. git diffall: shows diff between working tree and staged changes
|
|
2. git diffall --cached [<commit>]: shows diff between staged
|
|
changes and HEAD (or other named commit)
|
|
3. git diffall <commit>: shows diff between working tree and named
|
|
commit
|
|
4. git diffall <commit> <commit>: show diff between two named commits
|
|
5. git diffall <commit>..<commit>: same as above
|
|
6. git diffall <commit>...<commit>: show the changes on the branch
|
|
containing and up to the second, starting at a common ancestor
|
|
of both <commit>
|
|
|
|
Note: all forms take an optional path limiter [-- <path>*]
|
|
|
|
The '--extcmd=<command>' option allows the user to specify a custom
|
|
command for viewing diffs. When given, configured defaults are
|
|
ignored and the script runs $command $LOCAL $REMOTE. Additionally,
|
|
$BASE is set in the environment.

This script is based on an example provided by Thomas Rast on the
