1diff.autoRefreshIndex:: 2 When using 'git diff' to compare with work tree 3 files, do not consider stat-only change 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'. 10 11diff.dirstat:: 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: 18+ 19-- 20`changes`;; 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. 26`lines`;; 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. 34`files`;; 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. 39`cumulative`;; 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. 44<limit>;; 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. 48-- 49+ 50Example: The following will count changed files, while ignoring 51directories with less than 10% of the total amount of changed files, 52and accumulating child directory counts in the parent directories: 53`files,10,cumulative`. 54 55diff.statGraphWidth:: 56 Limit the width of the graph part in --stat output. If set, applies 57 to all commands generating --stat output except format-patch. 58 59diff.context:: 60 Generate diffs with <n> lines of context instead of the default 61 of 3. This value is overridden by the -U option. 62 63diff.interHunkContext:: 64 Show the context between diff hunks, up to the specified number 65 of lines, thereby fusing the hunks that are close to each other. 66 This value serves as the default for the `--inter-hunk-context` 67 command line option. 68 69diff.external:: 70 If this config variable is set, diff generation is not 71 performed using the internal diff machinery, but using the 72 given command. Can be overridden with the `GIT_EXTERNAL_DIFF' 73 environment variable. The command is called with parameters 74 as described under "git Diffs" in linkgit:git[1]. Note: if 75 you want to use an external diff program only on a subset of 76 your files, you might want to use linkgit:gitattributes[5] instead. 77 78diff.ignoreSubmodules:: 79 Sets the default value of --ignore-submodules. Note that this 80 affects only 'git diff' Porcelain, and not lower level 'diff' 81 commands such as 'git diff-files'. 'git checkout' 82 and 'git switch' also honor 83 this setting when reporting uncommitted changes. Setting it to 84 'all' disables the submodule summary normally shown by 'git commit' 85 and 'git status' when `status.submoduleSummary` is set unless it is 86 overridden by using the --ignore-submodules command-line option. 87 The 'git submodule' commands are not affected by this setting. 88 89diff.mnemonicPrefix:: 90 If set, 'git diff' uses a prefix pair that is different from the 91 standard "a/" and "b/" depending on what is being compared. When 92 this configuration is in effect, reverse diff output also swaps 93 the order of the prefixes: 94`git diff`;; 95 compares the (i)ndex and the (w)ork tree; 96`git diff HEAD`;; 97 compares a (c)ommit and the (w)ork tree; 98`git diff --cached`;; 99 compares a (c)ommit and the (i)ndex; 100`git diff HEAD:file1 file2`;; 101 compares an (o)bject and a (w)ork tree entity; 102`git diff --no-index a b`;; 103 compares two non-git things (1) and (2). 104 105diff.noprefix:: 106 If set, 'git diff' does not show any source or destination prefix. 107 108diff.orderFile:: 109 File indicating how to order files within a diff. 110 See the '-O' option to linkgit:git-diff[1] for details. 111 If `diff.orderFile` is a relative pathname, it is treated as 112 relative to the top of the working tree. 113 114diff.renameLimit:: 115 The number of files to consider when performing the copy/rename 116 detection; equivalent to the 'git diff' option `-l`. This setting 117 has no effect if rename detection is turned off. 118 119diff.renames:: 120 Whether and how Git detects renames. If set to "false", 121 rename detection is disabled. If set to "true", basic rename 122 detection is enabled. If set to "copies" or "copy", Git will 123 detect copies, as well. Defaults to true. Note that this 124 affects only 'git diff' Porcelain like linkgit:git-diff[1] and 125 linkgit:git-log[1], and not lower level commands such as 126 linkgit:git-diff-files[1]. 127 128diff.suppressBlankEmpty:: 129 A boolean to inhibit the standard behavior of printing a space 130 before each empty output line. Defaults to false. 131 132diff.submodule:: 133 Specify the format in which differences in submodules are 134 shown. The "short" format just shows the names of the commits 135 at the beginning and end of the range. The "log" format lists 136 the commits in the range like linkgit:git-submodule[1] `summary` 137 does. The "diff" format shows an inline diff of the changed 138 contents of the submodule. Defaults to "short". 139 140diff.wordRegex:: 141 A POSIX Extended Regular Expression used to determine what is a "word" 142 when performing word-by-word difference calculations. Character 143 sequences that match the regular expression are "words", all other 144 characters are *ignorable* whitespace. 145 146diff.<driver>.command:: 147 The custom diff driver command. See linkgit:gitattributes[5] 148 for details. 149 150diff.<driver>.xfuncname:: 151 The regular expression that the diff driver should use to 152 recognize the hunk header. A built-in pattern may also be used. 153 See linkgit:gitattributes[5] for details. 154 155diff.<driver>.binary:: 156 Set this option to true to make the diff driver treat files as 157 binary. See linkgit:gitattributes[5] for details. 158 159diff.<driver>.textconv:: 160 The command that the diff driver should call to generate the 161 text-converted version of a file. The result of the 162 conversion is used to generate a human-readable diff. See 163 linkgit:gitattributes[5] for details. 164 165diff.<driver>.wordRegex:: 166 The regular expression that the diff driver should use to 167 split words in a line. See linkgit:gitattributes[5] for 168 details. 169 170diff.<driver>.cachetextconv:: 171 Set this option to true to make the diff driver cache the text 172 conversion outputs. See linkgit:gitattributes[5] for details. 173 174diff.tool:: 175 Controls which diff tool is used by linkgit:git-difftool[1]. 176 This variable overrides the value configured in `merge.tool`. 177 The list below shows the valid built-in values. 178 Any other value is treated as a custom diff tool and requires 179 that a corresponding difftool.<tool>.cmd variable is defined. 180 181diff.guitool:: 182 Controls which diff tool is used by linkgit:git-difftool[1] when 183 the -g/--gui flag is specified. This variable overrides the value 184 configured in `merge.guitool`. The list below shows the valid 185 built-in values. Any other value is treated as a custom diff tool 186 and requires that a corresponding difftool.<guitool>.cmd variable 187 is defined. 188 189include::../mergetools-diff.txt[] 190 191diff.indentHeuristic:: 192 Set this option to `false` to disable the default heuristics 193 that shift diff hunk boundaries to make patches easier to read. 194 195diff.algorithm:: 196 Choose a diff algorithm. The variants are as follows: 197+ 198-- 199`default`, `myers`;; 200 The basic greedy diff algorithm. Currently, this is the default. 201`minimal`;; 202 Spend extra time to make sure the smallest possible diff is 203 produced. 204`patience`;; 205 Use "patience diff" algorithm when generating patches. 206`histogram`;; 207 This algorithm extends the patience algorithm to "support 208 low-occurrence common elements". 209-- 210+ 211 212diff.wsErrorHighlight:: 213 Highlight whitespace errors in the `context`, `old` or `new` 214 lines of the diff. Multiple values are separated by comma, 215 `none` resets previous values, `default` reset the list to 216 `new` and `all` is a shorthand for `old,new,context`. The 217 whitespace errors are colored with `color.diff.whitespace`. 218 The command line option `--ws-error-highlight=<kind>` 219 overrides this setting. 220 221diff.colorMoved:: 222 If set to either a valid `<mode>` or a true value, moved lines 223 in a diff are colored differently, for details of valid modes 224 see '--color-moved' in linkgit:git-diff[1]. If simply set to 225 true the default color mode will be used. When set to false, 226 moved lines are not colored. 227 228diff.colorMovedWS:: 229 When moved lines are colored using e.g. the `diff.colorMoved` setting, 230 this option controls the `<mode>` how spaces are treated 231 for details of valid modes see '--color-moved-ws' in linkgit:git-diff[1].
