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.external:: 12 If this config variable is set, diff generation is not 13 performed using the internal diff machinery, but using the 14 given command. Can be overridden with the `GIT_EXTERNAL_DIFF' 15 environment variable. The command is called with parameters 16 as described under "git Diffs" in linkgit:git[1]. Note: if 17 you want to use an external diff program only on a subset of 18 your files, you might want to use linkgit:gitattributes[5] instead. 19 20diff.ignoreSubmodules:: 21 Sets the default value of --ignore-submodules. Note that this 22 affects only 'git diff' Porcelain, and not lower level 'diff' 23 commands such as 'git diff-files'. 'git checkout' also honors 24 this setting when reporting uncommitted changes. 25 26diff.mnemonicprefix:: 27 If set, 'git diff' uses a prefix pair that is different from the 28 standard "a/" and "b/" depending on what is being compared. When 29 this configuration is in effect, reverse diff output also swaps 30 the order of the prefixes: 31`git diff`;; 32 compares the (i)ndex and the (w)ork tree; 33`git diff HEAD`;; 34 compares a (c)ommit and the (w)ork tree; 35`git diff --cached`;; 36 compares a (c)ommit and the (i)ndex; 37`git diff HEAD:file1 file2`;; 38 compares an (o)bject and a (w)ork tree entity; 39`git diff --no-index a b`;; 40 compares two non-git things (1) and (2). 41 42diff.noprefix:: 43 If set, 'git diff' does not show any source or destination prefix. 44 45diff.renameLimit:: 46 The number of files to consider when performing the copy/rename 47 detection; equivalent to the 'git diff' option '-l'. 48 49diff.renames:: 50 Tells git to detect renames. If set to any boolean value, it 51 will enable basic rename detection. If set to "copies" or 52 "copy", it will detect copies, as well. 53 54diff.suppressBlankEmpty:: 55 A boolean to inhibit the standard behavior of printing a space 56 before each empty output line. Defaults to false. 57 58diff.tool:: 59 Controls which diff tool is used. `diff.tool` overrides 60 `merge.tool` when used by linkgit:git-difftool[1] and has 61 the same valid values as `merge.tool` minus "tortoisemerge" 62 and plus "kompare".
