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 of 61 3. This value is overridden by the -U option. 62 63diff.external:: 64 If this config variable is set, diff generation is not 65 performed using the internal diff machinery, but using the 66 given command. Can be overridden with the `GIT_EXTERNAL_DIFF' 67 environment variable. The command is called with parameters 68 as described under "git Diffs" in linkgit:git[1]. Note: if 69 you want to use an external diff program only on a subset of 70 your files, you might want to use linkgit:gitattributes[5] instead. 71 72diff.ignoreSubmodules:: 73 Sets the default value of --ignore-submodules. Note that this 74 affects only 'git diff' Porcelain, and not lower level 'diff' 75 commands such as 'git diff-files'. 'git checkout' also honors 76 this setting when reporting uncommitted changes. 77 78diff.mnemonicprefix:: 79 If set, 'git diff' uses a prefix pair that is different from the 80 standard "a/" and "b/" depending on what is being compared. When 81 this configuration is in effect, reverse diff output also swaps 82 the order of the prefixes: 83`git diff`;; 84 compares the (i)ndex and the (w)ork tree; 85`git diff HEAD`;; 86 compares a (c)ommit and the (w)ork tree; 87`git diff --cached`;; 88 compares a (c)ommit and the (i)ndex; 89`git diff HEAD:file1 file2`;; 90 compares an (o)bject and a (w)ork tree entity; 91`git diff --no-index a b`;; 92 compares two non-git things (1) and (2). 93 94diff.noprefix:: 95 If set, 'git diff' does not show any source or destination prefix. 96 97diff.renameLimit:: 98 The number of files to consider when performing the copy/rename 99 detection; equivalent to the 'git diff' option '-l'. 100 101diff.renames:: 102 Tells git to detect renames. If set to any boolean value, it 103 will enable basic rename detection. If set to "copies" or 104 "copy", it will detect copies, as well. 105 106diff.suppressBlankEmpty:: 107 A boolean to inhibit the standard behavior of printing a space 108 before each empty output line. Defaults to false. 109 110diff.submodule:: 111 Specify the format in which differences in submodules are 112 shown. The "log" format lists the commits in the range like 113 linkgit:git-submodule[1] `summary` does. The "short" format 114 format just shows the names of the commits at the beginning 115 and end of the range. Defaults to short. 116 117diff.wordRegex:: 118 A POSIX Extended Regular Expression used to determine what is a "word" 119 when performing word-by-word difference calculations. Character 120 sequences that match the regular expression are "words", all other 121 characters are *ignorable* whitespace. 122 123diff.<driver>.command:: 124 The custom diff driver command. See linkgit:gitattributes[5] 125 for details. 126 127diff.<driver>.xfuncname:: 128 The regular expression that the diff driver should use to 129 recognize the hunk header. A built-in pattern may also be used. 130 See linkgit:gitattributes[5] for details. 131 132diff.<driver>.binary:: 133 Set this option to true to make the diff driver treat files as 134 binary. See linkgit:gitattributes[5] for details. 135 136diff.<driver>.textconv:: 137 The command that the diff driver should call to generate the 138 text-converted version of a file. The result of the 139 conversion is used to generate a human-readable diff. See 140 linkgit:gitattributes[5] for details. 141 142diff.<driver>.wordregex:: 143 The regular expression that the diff driver should use to 144 split words in a line. See linkgit:gitattributes[5] for 145 details. 146 147diff.<driver>.cachetextconv:: 148 Set this option to true to make the diff driver cache the text 149 conversion outputs. See linkgit:gitattributes[5] for details. 150 151diff.tool:: 152 The diff tool to be used by linkgit:git-difftool[1]. This 153 option overrides `merge.tool`, and has the same valid built-in 154 values as `merge.tool` minus "tortoisemerge" and plus 155 "kompare". Any other value is treated as a custom diff tool, 156 and there must be a corresponding `difftool.<tool>.cmd` 157 option.
