| diff.autorefreshindex:: |
| When using 'git diff' to compare with work tree |
| files, do not consider stat-only change as changed. |
| Instead, silently run `git update-index --refresh` to |
| update the cached stat information for paths whose |
| contents in the work tree match the contents in the |
| index. This option defaults to true. Note that this |
| affects only 'git diff' Porcelain, and not lower level |
| 'diff' commands such as 'git diff-files'. |
| |
| diff.dirstat:: |
| A comma separated list of `--dirstat` parameters specifying the |
| default behavior of the `--dirstat` option to linkgit:git-diff[1]` |
| and friends. The defaults can be overridden on the command line |
| (using `--dirstat=<param1,param2,...>`). The fallback defaults |
| (when not changed by `diff.dirstat`) are `changes,noncumulative,3`. |
| The following parameters are available: |
| + |
| -- |
| `changes`;; |
| Compute the dirstat numbers by counting the lines that have been |
| removed from the source, or added to the destination. This ignores |
| the amount of pure code movements within a file. In other words, |
| rearranging lines in a file is not counted as much as other changes. |
| This is the default behavior when no parameter is given. |
| `lines`;; |
| Compute the dirstat numbers by doing the regular line-based diff |
| analysis, and summing the removed/added line counts. (For binary |
| files, count 64-byte chunks instead, since binary files have no |
| natural concept of lines). This is a more expensive `--dirstat` |
| behavior than the `changes` behavior, but it does count rearranged |
| lines within a file as much as other changes. The resulting output |
| is consistent with what you get from the other `--*stat` options. |
| `files`;; |
| Compute the dirstat numbers by counting the number of files changed. |
| Each changed file counts equally in the dirstat analysis. This is |
| the computationally cheapest `--dirstat` behavior, since it does |
| not have to look at the file contents at all. |
| `cumulative`;; |
| Count changes in a child directory for the parent directory as well. |
| Note that when using `cumulative`, the sum of the percentages |
| reported may exceed 100%. The default (non-cumulative) behavior can |
| be specified with the `noncumulative` parameter. |
| <limit>;; |
| An integer parameter specifies a cut-off percent (3% by default). |
| Directories contributing less than this percentage of the changes |
| are not shown in the output. |
| -- |
| + |
| Example: The following will count changed files, while ignoring |
| directories with less than 10% of the total amount of changed files, |
| and accumulating child directory counts in the parent directories: |
| `files,10,cumulative`. |
| |
| diff.statGraphWidth:: |
| Limit the width of the graph part in --stat output. If set, applies |
| to all commands generating --stat output except format-patch. |
| |
| diff.context:: |
| Generate diffs with <n> lines of context instead of the default |
| of 3. This value is overridden by the -U option. |
| |
| diff.external:: |
| If this config variable is set, diff generation is not |
| performed using the internal diff machinery, but using the |
| given command. Can be overridden with the `GIT_EXTERNAL_DIFF' |
| environment variable. The command is called with parameters |
| as described under "git Diffs" in linkgit:git[1]. Note: if |
| you want to use an external diff program only on a subset of |
| your files, you might want to use linkgit:gitattributes[5] instead. |
| |
| diff.ignoreSubmodules:: |
| Sets the default value of --ignore-submodules. Note that this |
| affects only 'git diff' Porcelain, and not lower level 'diff' |
| commands such as 'git diff-files'. 'git checkout' also honors |
| this setting when reporting uncommitted changes. |
| |
| diff.mnemonicprefix:: |
| If set, 'git diff' uses a prefix pair that is different from the |
| standard "a/" and "b/" depending on what is being compared. When |
| this configuration is in effect, reverse diff output also swaps |
| the order of the prefixes: |
| `git diff`;; |
| compares the (i)ndex and the (w)ork tree; |
| `git diff HEAD`;; |
| compares a (c)ommit and the (w)ork tree; |
| `git diff --cached`;; |
| compares a (c)ommit and the (i)ndex; |
| `git diff HEAD:file1 file2`;; |
| compares an (o)bject and a (w)ork tree entity; |
| `git diff --no-index a b`;; |
| compares two non-git things (1) and (2). |
| |
| diff.noprefix:: |
| If set, 'git diff' does not show any source or destination prefix. |
| |
| diff.renameLimit:: |
| The number of files to consider when performing the copy/rename |
| detection; equivalent to the 'git diff' option '-l'. |
| |
| diff.renames:: |
| Tells Git to detect renames. If set to any boolean value, it |
| will enable basic rename detection. If set to "copies" or |
| "copy", it will detect copies, as well. |
| |
| diff.suppressBlankEmpty:: |
| A boolean to inhibit the standard behavior of printing a space |
| before each empty output line. Defaults to false. |
| |
| diff.submodule:: |
| Specify the format in which differences in submodules are |
| shown. The "log" format lists the commits in the range like |
| linkgit:git-submodule[1] `summary` does. The "short" format |
| format just shows the names of the commits at the beginning |
| and end of the range. Defaults to short. |
| |
| diff.wordRegex:: |
| A POSIX Extended Regular Expression used to determine what is a "word" |
| when performing word-by-word difference calculations. Character |
| sequences that match the regular expression are "words", all other |
| characters are *ignorable* whitespace. |
| |
| diff.<driver>.command:: |
| The custom diff driver command. See linkgit:gitattributes[5] |
| for details. |
| |
| diff.<driver>.xfuncname:: |
| The regular expression that the diff driver should use to |
| recognize the hunk header. A built-in pattern may also be used. |
| See linkgit:gitattributes[5] for details. |
| |
| diff.<driver>.binary:: |
| Set this option to true to make the diff driver treat files as |
| binary. See linkgit:gitattributes[5] for details. |
| |
| diff.<driver>.textconv:: |
| The command that the diff driver should call to generate the |
| text-converted version of a file. The result of the |
| conversion is used to generate a human-readable diff. See |
| linkgit:gitattributes[5] for details. |
| |
| diff.<driver>.wordregex:: |
| The regular expression that the diff driver should use to |
| split words in a line. See linkgit:gitattributes[5] for |
| details. |
| |
| diff.<driver>.cachetextconv:: |
| Set this option to true to make the diff driver cache the text |
| conversion outputs. See linkgit:gitattributes[5] for details. |
| |
| diff.tool:: |
| Controls which diff tool is used by linkgit:git-difftool[1]. |
| This variable overrides the value configured in `merge.tool`. |
| The list below shows the valid built-in values. |
| Any other value is treated as a custom diff tool and requires |
| that a corresponding difftool.<tool>.cmd variable is defined. |
| |
| include::mergetools-diff.txt[] |
| |
| diff.algorithm:: |
| Choose a diff algorithm. The variants are as follows: |
| + |
| -- |
| `default`, `myers`;; |
| The basic greedy diff algorithm. Currently, this is the default. |
| `minimal`;; |
| Spend extra time to make sure the smallest possible diff is |
| produced. |
| `patience`;; |
| Use "patience diff" algorithm when generating patches. |
| `histogram`;; |
| This algorithm extends the patience algorithm to "support |
| low-occurrence common elements". |

| + |
