1// Please don't remove this comment as asciidoc behaves badly when 2// the first non-empty line is ifdef/ifndef. The symptom is that 3// without this comment the <git-diff-core> attribute conditionally 4// defined below ends up being defined unconditionally. 5// Last checked with asciidoc 7.0.2. 6 7ifndef::git-format-patch[] 8ifndef::git-diff[] 9ifndef::git-log[] 10:git-diff-core: 1 11endif::git-log[] 12endif::git-diff[] 13endif::git-format-patch[] 14 15ifdef::git-format-patch[] 16-p:: 17 Generate patches without diffstat. 18endif::git-format-patch[] 19 20ifndef::git-format-patch[] 21-p:: 22 Generate patch (see section on generating patches). 23 {git-diff? This is the default.} 24endif::git-format-patch[] 25 26-u:: 27 Synonym for "-p". 28 29-U<n>:: 30 Shorthand for "--unified=<n>". 31 32--unified=<n>:: 33 Generate diffs with <n> lines of context instead of 34 the usual three. Implies "-p". 35 36--raw:: 37 Generate the raw format. 38 {git-diff-core? This is the default.} 39 40--patch-with-raw:: 41 Synonym for "-p --raw". 42 43--stat[=width[,name-width]]:: 44 Generate a diffstat. You can override the default 45 output width for 80-column terminal by "--stat=width". 46 The width of the filename part can be controlled by 47 giving another width to it separated by a comma. 48 49--numstat:: 50 Similar to \--stat, but shows number of added and 51 deleted lines in decimal notation and pathname without 52 abbreviation, to make it more machine friendly. For 53 binary files, outputs two `-` instead of saying 54 `0 0`. 55 56--shortstat:: 57 Output only the last line of the --stat format containing total 58 number of modified files, as well as number of added and deleted 59 lines. 60 61--dirstat[=limit]:: 62 Output the distribution of relative amount of changes (number of lines added or 63 removed) for each sub-directory. Directories with changes below 64 a cut-off percent (3% by default) are not shown. The cut-off percent 65 can be set with "--dirstat=limit". Changes in a child directory is not 66 counted for the parent directory, unless "--cumulative" is used. 67 68--dirstat-by-file[=limit]:: 69 Same as --dirstat, but counts changed files instead of lines. 70 71--summary:: 72 Output a condensed summary of extended header information 73 such as creations, renames and mode changes. 74 75--patch-with-stat:: 76 Synonym for "-p --stat". 77 {git-format-patch? This is the default.} 78 79-z:: 80 NUL-line termination on output. This affects the --raw 81 output field terminator. Also output from commands such 82 as "git-log" will be delimited with NUL between commits. 83 84--name-only:: 85 Show only names of changed files. 86 87--name-status:: 88 Show only names and status of changed files. See the description 89 of the `--diff-filter` option on what the status letters mean. 90 91--color:: 92 Show colored diff. 93 94--no-color:: 95 Turn off colored diff, even when the configuration file 96 gives the default to color output. 97 98--color-words:: 99 Show colored word diff, i.e. color words which have changed. 100 101--no-renames:: 102 Turn off rename detection, even when the configuration 103 file gives the default to do so. 104 105--check:: 106 Warn if changes introduce trailing whitespace 107 or an indent that uses a space before a tab. Exits with 108 non-zero status if problems are found. Not compatible with 109 --exit-code. 110 111--full-index:: 112 Instead of the first handful of characters, show the full 113 pre- and post-image blob object names on the "index" 114 line when generating patch format output. 115 116--binary:: 117 In addition to --full-index, output "binary diff" that 118 can be applied with "git apply". 119 120--abbrev[=<n>]:: 121 Instead of showing the full 40-byte hexadecimal object 122 name in diff-raw format output and diff-tree header 123 lines, show only handful hexdigits prefix. This is 124 independent of --full-index option above, which controls 125 the diff-patch output format. Non default number of 126 digits can be specified with --abbrev=<n>. 127 128-B:: 129 Break complete rewrite changes into pairs of delete and create. 130 131-M:: 132 Detect renames. 133 134-C:: 135 Detect copies as well as renames. See also `--find-copies-harder`. 136 137--diff-filter=[ACDMRTUXB*]:: 138 Select only files that are Added (`A`), Copied (`C`), 139 Deleted (`D`), Modified (`M`), Renamed (`R`), have their 140 type (mode) changed (`T`), are Unmerged (`U`), are 141 Unknown (`X`), or have had their pairing Broken (`B`). 142 Any combination of the filter characters may be used. 143 When `*` (All-or-none) is added to the combination, all 144 paths are selected if there is any file that matches 145 other criteria in the comparison; if there is no file 146 that matches other criteria, nothing is selected. 147 148--find-copies-harder:: 149 For performance reasons, by default, `-C` option finds copies only 150 if the original file of the copy was modified in the same 151 changeset. This flag makes the command 152 inspect unmodified files as candidates for the source of 153 copy. This is a very expensive operation for large 154 projects, so use it with caution. Giving more than one 155 `-C` option has the same effect. 156 157-l<num>:: 158 -M and -C options require O(n^2) processing time where n 159 is the number of potential rename/copy targets. This 160 option prevents rename/copy detection from running if 161 the number of rename/copy targets exceeds the specified 162 number. 163 164-S<string>:: 165 Look for differences that contain the change in <string>. 166 167--pickaxe-all:: 168 When -S finds a change, show all the changes in that 169 changeset, not just the files that contain the change 170 in <string>. 171 172--pickaxe-regex:: 173 Make the <string> not a plain string but an extended POSIX 174 regex to match. 175 176-O<orderfile>:: 177 Output the patch in the order specified in the 178 <orderfile>, which has one shell glob pattern per line. 179 180-R:: 181 Swap two inputs; that is, show differences from index or 182 on-disk file to tree contents. 183 184--relative[=<path>]:: 185 When run from a subdirectory of the project, it can be 186 told to exclude changes outside the directory and show 187 pathnames relative to it with this option. When you are 188 not in a subdirectory (e.g. in a bare repository), you 189 can name which subdirectory to make the output relative 190 to by giving a <path> as an argument. 191 192--text:: 193 Treat all files as text. 194 195-a:: 196 Shorthand for "--text". 197 198--ignore-space-at-eol:: 199 Ignore changes in whitespace at EOL. 200 201--ignore-space-change:: 202 Ignore changes in amount of whitespace. This ignores whitespace 203 at line end, and considers all other sequences of one or 204 more whitespace characters to be equivalent. 205 206-b:: 207 Shorthand for "--ignore-space-change". 208 209--ignore-all-space:: 210 Ignore whitespace when comparing lines. This ignores 211 differences even if one line has whitespace where the other 212 line has none. 213 214-w:: 215 Shorthand for "--ignore-all-space". 216 217--exit-code:: 218 Make the program exit with codes similar to diff(1). 219 That is, it exits with 1 if there were differences and 220 0 means no differences. 221 222--quiet:: 223 Disable all output of the program. Implies --exit-code. 224 225--ext-diff:: 226 Allow an external diff helper to be executed. If you set an 227 external diff driver with linkgit:gitattributes[5], you need 228 to use this option with linkgit:git-log[1] and friends. 229 230--no-ext-diff:: 231 Disallow external diff drivers. 232 233--ignore-submodules:: 234 Ignore changes to submodules in the diff generation. 235 236--src-prefix=<prefix>:: 237 Show the given source prefix instead of "a/". 238 239--dst-prefix=<prefix>:: 240 Show the given destination prefix instead of "b/". 241 242--no-prefix:: 243 Do not show any source or destination prefix. 244 245For more detailed explanation on these common options, see also 246linkgit:gitdiffcore[7].
