1 diff.autoRefreshIndex::
2 When using 'git diff' to compare with work tree
3 files, do not consider stat-only changes as changed.
4 Instead, silently run `git update-index --refresh` to
5 update the cached stat information for paths whose
6 contents in the work tree match the contents in the
7 index. This option defaults to true. Note that this
8 affects only 'git diff' Porcelain, and not lower level
9 'diff' commands such as 'git diff-files'.
12 A comma separated list of `--dirstat` parameters specifying the
13 default behavior of the `--dirstat` option to linkgit:git-diff[1]
14 and friends. The defaults can be overridden on the command line
15 (using `--dirstat=<param1,param2,...>`). The fallback defaults
16 (when not changed by `diff.dirstat`) are `changes,noncumulative,3`.
17 The following parameters are available:
21 Compute the dirstat numbers by counting the lines that have been
22 removed from the source, or added to the destination. This ignores
23 the amount of pure code movements within a file. In other words,
24 rearranging lines in a file is not counted as much as other changes.
25 This is the default behavior when no parameter is given.
27 Compute the dirstat numbers by doing the regular line-based diff
28 analysis, and summing the removed/added line counts. (For binary
29 files, count 64-byte chunks instead, since binary files have no
30 natural concept of lines). This is a more expensive `--dirstat`
31 behavior than the `changes` behavior, but it does count rearranged
32 lines within a file as much as other changes. The resulting output
33 is consistent with what you get from the other `--*stat` options.
35 Compute the dirstat numbers by counting the number of files changed.
36 Each changed file counts equally in the dirstat analysis. This is
37 the computationally cheapest `--dirstat` behavior, since it does
38 not have to look at the file contents at all.
40 Count changes in a child directory for the parent directory as well.
41 Note that when using `cumulative`, the sum of the percentages
42 reported may exceed 100%. The default (non-cumulative) behavior can
43 be specified with the `noncumulative` parameter.
45 An integer parameter specifies a cut-off percent (3% by default).
46 Directories contributing less than this percentage of the changes
47 are not shown in the output.
50 Example: The following will count changed files, while ignoring
51 directories with less than 10% of the total amount of changed files,
52 and accumulating child directory counts in the parent directories:
53 `files,10,cumulative`.
56 Limit the width of the filename part in --stat output. If set, applies
57 to all commands generating --stat output except format-patch.
60 Limit the width of the graph part in --stat output. If set, applies
61 to all commands generating --stat output except format-patch.
64 Generate diffs with <n> lines of context instead of the default
65 of 3. This value is overridden by the -U option.
67 diff.interHunkContext::
68 Show the context between diff hunks, up to the specified number
69 of lines, thereby fusing the hunks that are close to each other.
70 This value serves as the default for the `--inter-hunk-context`
74 If this config variable is set, diff generation is not
75 performed using the internal diff machinery, but using the
76 given command. Can be overridden with the `GIT_EXTERNAL_DIFF'
77 environment variable. The command is called with parameters
78 as described under "git Diffs" in linkgit:git[1]. Note: if
79 you want to use an external diff program only on a subset of
80 your files, you might want to use linkgit:gitattributes[5] instead.
83 If this boolean value is set to true then the
84 `diff.external` command is expected to return exit code
85 0 if it considers the input files to be equal or 1 if it
86 considers them to be different, like `diff(1)`.
87 If it is set to false, which is the default, then the command
88 is expected to return exit code 0 regardless of equality.
89 Any other exit code causes Git to report a fatal error.
91 diff.ignoreSubmodules::
92 Sets the default value of --ignore-submodules. Note that this
93 affects only 'git diff' Porcelain, and not lower level 'diff'
94 commands such as 'git diff-files'. 'git checkout'
95 and 'git switch' also honor
96 this setting when reporting uncommitted changes. Setting it to
97 'all' disables the submodule summary normally shown by 'git commit'
98 and 'git status' when `status.submoduleSummary` is set unless it is
99 overridden by using the --ignore-submodules command-line option.
100 The 'git submodule' commands are not affected by this setting.
101 By default this is set to untracked so that any untracked
102 submodules are ignored.
104 diff.mnemonicPrefix::
105 If set, 'git diff' uses a prefix pair that is different from the
106 standard "a/" and "b/" depending on what is being compared. When
107 this configuration is in effect, reverse diff output also swaps
108 the order of the prefixes:
110 compares the (i)ndex and the (w)ork tree;
112 compares a (c)ommit and the (w)ork tree;
113 `git diff --cached`;;
114 compares a (c)ommit and the (i)ndex;
115 `git diff HEAD:file1 file2`;;
116 compares an (o)bject and a (w)ork tree entity;
117 `git diff --no-index a b`;;
118 compares two non-git things (1) and (2).
121 If set, 'git diff' does not show any source or destination prefix.
124 If set, 'git diff' uses this source prefix. Defaults to "a/".
127 If set, 'git diff' uses this destination prefix. Defaults to "b/".
130 If set to 'true', 'git diff' does not show changes outside of the directory
131 and show pathnames relative to the current directory.
134 File indicating how to order files within a diff.
135 See the '-O' option to linkgit:git-diff[1] for details.
136 If `diff.orderFile` is a relative pathname, it is treated as
137 relative to the top of the working tree.
140 The number of files to consider in the exhaustive portion of
141 copy/rename detection; equivalent to the 'git diff' option
142 `-l`. If not set, the default value is currently 1000. This
143 setting has no effect if rename detection is turned off.
146 Whether and how Git detects renames. If set to "false",
147 rename detection is disabled. If set to "true", basic rename
148 detection is enabled. If set to "copies" or "copy", Git will
149 detect copies, as well. Defaults to true. Note that this
150 affects only 'git diff' Porcelain like linkgit:git-diff[1] and
151 linkgit:git-log[1], and not lower level commands such as
152 linkgit:git-diff-files[1].
154 diff.suppressBlankEmpty::
155 A boolean to inhibit the standard behavior of printing a space
156 before each empty output line. Defaults to false.
159 Specify the format in which differences in submodules are
160 shown. The "short" format just shows the names of the commits
161 at the beginning and end of the range. The "log" format lists
162 the commits in the range like linkgit:git-submodule[1] `summary`
163 does. The "diff" format shows an inline diff of the changed
164 contents of the submodule. Defaults to "short".
167 A POSIX Extended Regular Expression used to determine what is a "word"
168 when performing word-by-word difference calculations. Character
169 sequences that match the regular expression are "words", all other
170 characters are *ignorable* whitespace.
172 diff.<driver>.command::
173 The custom diff driver command. See linkgit:gitattributes[5]
176 diff.<driver>.trustExitCode::
177 If this boolean value is set to true then the
178 `diff.<driver>.command` command is expected to return exit code
179 0 if it considers the input files to be equal or 1 if it
180 considers them to be different, like `diff(1)`.
181 If it is set to false, which is the default, then the command
182 is expected to return exit code 0 regardless of equality.
183 Any other exit code causes Git to report a fatal error.
185 diff.<driver>.xfuncname::
186 The regular expression that the diff driver should use to
187 recognize the hunk header. A built-in pattern may also be used.
188 See linkgit:gitattributes[5] for details.
190 diff.<driver>.binary::
191 Set this option to true to make the diff driver treat files as
192 binary. See linkgit:gitattributes[5] for details.
194 diff.<driver>.textconv::
195 The command that the diff driver should call to generate the
196 text-converted version of a file. The result of the
197 conversion is used to generate a human-readable diff. See
198 linkgit:gitattributes[5] for details.
200 diff.<driver>.wordRegex::
201 The regular expression that the diff driver should use to
202 split words in a line. See linkgit:gitattributes[5] for
205 diff.<driver>.cachetextconv::
206 Set this option to true to make the diff driver cache the text
207 conversion outputs. See linkgit:gitattributes[5] for details.
209 include::../mergetools-diff.txt[]
211 diff.indentHeuristic::
212 Set this option to `false` to disable the default heuristics
213 that shift diff hunk boundaries to make patches easier to read.
216 Choose a diff algorithm. The variants are as follows:
220 The basic greedy diff algorithm. Currently, this is the default.
222 Spend extra time to make sure the smallest possible diff is
225 Use "patience diff" algorithm when generating patches.
227 This algorithm extends the patience algorithm to "support
228 low-occurrence common elements".
232 diff.wsErrorHighlight::
233 Highlight whitespace errors in the `context`, `old` or `new`
234 lines of the diff. Multiple values are separated by comma,
235 `none` resets previous values, `default` reset the list to
236 `new` and `all` is a shorthand for `old,new,context`. The
237 whitespace errors are colored with `color.diff.whitespace`.
238 The command line option `--ws-error-highlight=<kind>`
239 overrides this setting.
242 If set to either a valid `<mode>` or a true value, moved lines
243 in a diff are colored differently, for details of valid modes
244 see '--color-moved' in linkgit:git-diff[1]. If simply set to
245 true the default color mode will be used. When set to false,
246 moved lines are not colored.
249 When moved lines are colored using e.g. the `diff.colorMoved` setting,
250 this option controls the `<mode>` how spaces are treated.
251 For details of valid modes see '--color-moved-ws' in linkgit:git-diff[1].
