--m::
+`-m`::
Show diffs for merge commits in the default format. This is
similar to `--diff-merges=on`, except `-m` will
produce no output unless `-p` is given as well.
--c::
+`-c`::
Produce combined diff output for merge commits.
Shortcut for `--diff-merges=combined -p`.
---cc::
+`--cc`::
Produce dense combined diff output for merge commits.
Shortcut for `--diff-merges=dense-combined -p`.
---dd::
+`--dd`::
Produce diff with respect to first parent for both merge and
regular commits.
Shortcut for `--diff-merges=first-parent -p`.
---remerge-diff::
+`--remerge-diff`::
Produce remerge-diff output for merge commits.
Shortcut for `--diff-merges=remerge -p`.
---no-diff-merges::
+`--no-diff-merges`::
Synonym for `--diff-merges=off`.
---diff-merges=<format>::
+`--diff-merges=<format>`::
Specify diff format to be used for merge commits. Default is
{diff-merges-default} unless `--first-parent` is in use, in
which case `first-parent` is the default.
The following formats are supported:
+
--
-off, none::
+`off`::
+`none`::
Disable output of diffs for merge commits. Useful to override
implied value.
-on, m::
+`on`::
+`m`::
Make diff output for merge commits to be shown in the default
format. The default format can be changed using
`log.diffMerges` configuration variable, whose default value
is `separate`.
-first-parent, 1::
+`first-parent`::
+`1`::
Show full diff with respect to first parent. This is the same
format as `--patch` produces for non-merge commits.
-separate::
+`separate`::
Show full diff with respect to each of parents.
Separate log entry and diff is generated for each parent.
-combined, c::
+`combined`::
+`c`::
Show differences from each of the parents to the merge
result simultaneously instead of showing pairwise diff between
a parent and the result one at a time. Furthermore, it lists
only files which were modified from all parents.
-dense-combined, cc::
+`dense-combined`::
+`cc`::
Further compress output produced by `--diff-merges=combined`
by omitting uninteresting hunks whose contents in the parents
have only two variants and the merge result picks one of them
without modification.
-remerge, r::
- Remerge two-parent merge commits to create a temporary tree
+`remerge`::
+`r`:: Remerge two-parent merge commits to create a temporary tree
object--potentially containing files with conflict markers
and such. A diff is then shown between that temporary tree
and the actual merge commit.
+--
+
The output emitted when this option is used is subject to change, and
so is its interaction with other options (unless explicitly
documented).
---
---combined-all-paths::
+
+`--combined-all-paths`::
Cause combined diffs (used for merge commits) to
list the name of the file from all parents. It thus only has
effect when `--diff-merges=[dense-]combined` is in use, and
