ifndef::git-format-patch[]
-p::
+-u::
Generate patch (see section on generating patches).
{git-diff? This is the default.}
endif::git-format-patch[]
--u::
- Synonym for "-p".
-
-U<n>::
- Shorthand for "--unified=<n>".
-
--unified=<n>::
Generate diffs with <n> lines of context instead of
the usual three. Implies "-p".
--patch-with-raw::
Synonym for "-p --raw".
+--patience::
+ Generate a diff using the "patience diff" algorithm.
+
--stat[=width[,name-width]]::
Generate a diffstat. You can override the default
output width for 80-column terminal by "--stat=width".
lines.
--dirstat[=limit]::
- Output only the sub-directories that are impacted by a diff,
- and to what degree they are impacted. You can override the
- default cut-off in percent (3) by "--dirstat=limit". If you
- want to enable "cumulative" directory statistics, you can use
- the "--cumulative" flag, which adds up percentages recursively
- even when they have been already reported for a sub-directory.
+ Output the distribution of relative amount of changes (number of lines added or
+ removed) for each sub-directory. Directories with changes below
+ a cut-off percent (3% by default) are not shown. The cut-off percent
+ can be set with "--dirstat=limit". Changes in a child directory is not
+ counted for the parent directory, unless "--cumulative" is used.
+
+--dirstat-by-file[=limit]::
+ Same as --dirstat, but counts changed files instead of lines.
--summary::
Output a condensed summary of extended header information
Turn off colored diff, even when the configuration file
gives the default to color output.
---color-words::
- Show colored word diff, i.e. color words which have changed.
+--color-words[=<regex>]::
+ Show colored word diff, i.e., color words which have changed.
+ By default, words are separated by whitespace.
++
+When a <regex> is specified, every non-overlapping match of the
+<regex> is considered a word. Anything between these matches is
+considered whitespace and ignored(!) for the purposes of finding
+differences. You may want to append `|[^[:space:]]` to your regular
+expression to make sure that it matches all non-whitespace characters.
+A match that contains a newline is silently truncated(!) at the
+newline.
++
+The regex can also be set via a diff driver or configuration option, see
+linkgit:gitattributes[1] or linkgit:git-config[1]. Giving it explicitly
+overrides any diff driver or configuration setting. Diff drivers
+override configuration settings.
--no-renames::
Turn off rename detection, even when the configuration
--exit-code.
--full-index::
- Instead of the first handful characters, show full
- object name of pre- and post-image blob on the "index"
- line when generating a patch format output.
+ Instead of the first handful of characters, show the full
+ pre- and post-image blob object names on the "index"
+ line when generating patch format output.
--binary::
In addition to --full-index, output "binary diff" that
--abbrev[=<n>]::
Instead of showing the full 40-byte hexadecimal object
name in diff-raw format output and diff-tree header
- lines, show only handful hexdigits prefix. This is
+ lines, show only a partial prefix. This is
independent of --full-index option above, which controls
the diff-patch output format. Non default number of
digits can be specified with --abbrev=<n>.
--diff-filter=[ACDMRTUXB*]::
Select only files that are Added (`A`), Copied (`C`),
Deleted (`D`), Modified (`M`), Renamed (`R`), have their
- type (mode) changed (`T`), are Unmerged (`U`), are
+ type (i.e. regular file, symlink, submodule, ...) changed (`T`),
+ are Unmerged (`U`), are
Unknown (`X`), or have had their pairing Broken (`B`).
Any combination of the filter characters may be used.
When `*` (All-or-none) is added to the combination, all
number.
-S<string>::
- Look for differences that contain the change in <string>.
+ Look for differences that introduce or remove an instance of
+ <string>. Note that this is different than the string simply
+ appearing in diff output; see the 'pickaxe' entry in
+ linkgit:gitdiffcore[7] for more details.
--pickaxe-all::
When -S finds a change, show all the changes in that
can name which subdirectory to make the output relative
to by giving a <path> as an argument.
+-a::
--text::
Treat all files as text.
--a::
- Shorthand for "--text".
-
--ignore-space-at-eol::
Ignore changes in whitespace at EOL.
+-b::
--ignore-space-change::
Ignore changes in amount of whitespace. This ignores whitespace
at line end, and considers all other sequences of one or
more whitespace characters to be equivalent.
--b::
- Shorthand for "--ignore-space-change".
-
+-w::
--ignore-all-space::
Ignore whitespace when comparing lines. This ignores
differences even if one line has whitespace where the other
line has none.
--w::
- Shorthand for "--ignore-all-space".
+--inter-hunk-context=<lines>::
+ Show the context between diff hunks, up to the specified number
+ of lines, thereby fusing hunks that are close to each other.
--exit-code::
Make the program exit with codes similar to diff(1).
