   1 PRETTY FORMATS
   2 --------------
   3
   4 If the commit is a merge, and if the pretty-format
   5 is not 'oneline', 'email' or 'raw', an additional line is
   6 inserted before the 'Author:' line.  This line begins with
   7 "Merge: " and the hashes of ancestral commits are printed,
   8 separated by spaces.  Note that the listed commits may not
   9 necessarily be the list of the *direct* parent commits if you
  10 have limited your view of history: for example, if you are
  11 only interested in changes related to a certain directory or
  12 file.
  13
  14 There are several built-in formats, and you can define
  15 additional formats by setting a pretty.<name>
  16 config option to either another format name, or a
  17 'format:' string, as described below (see
  18 linkgit:git-config[1]). Here are the details of the
  19 built-in formats:
  20
  21 * 'oneline'
  22
  23           <hash> <title line>
  24 +
  25 This is designed to be as compact as possible.
  26
  27 * 'short'
  28
  29           commit <hash>
  30           Author: <author>
  31
  32               <title line>
  33
  34 * 'medium'
  35
  36           commit <hash>
  37           Author: <author>
  38           Date:   <author date>
  39
  40               <title line>
  41
  42               <full commit message>
  43
  44 * 'full'
  45
  46           commit <hash>
  47           Author: <author>
  48           Commit: <committer>
  49
  50               <title line>
  51
  52               <full commit message>
  53
  54 * 'fuller'
  55
  56           commit <hash>
  57           Author:     <author>
  58           AuthorDate: <author date>
  59           Commit:     <committer>
  60           CommitDate: <committer date>
  61
  62                <title line>
  63
  64                <full commit message>
  65
  66 * 'reference'
  67
  68           <abbrev hash> (<title line>, <short author date>)
  69 +
  70 This format is used to refer to another commit in a commit message and
  71 is the same as `--pretty='format:%C(auto)%h (%s, %ad)'`.  By default,
  72 the date is formatted with `--date=short` unless another `--date` option
  73 is explicitly specified.  As with any `format:` with format
  74 placeholders, its output is not affected by other options like
  75 `--decorate` and `--walk-reflogs`.
  76
  77 * 'email'
  78
  79           From <hash> <date>
  80           From: <author>
  81           Date: <author date>
  82           Subject: [PATCH] <title line>
  83
  84           <full commit message>
  85
  86 * 'mboxrd'
  87 +
  88 Like 'email', but lines in the commit message starting with "From "
  89 (preceded by zero or more ">") are quoted with ">" so they aren't
  90 confused as starting a new commit.
  91
  92 * 'raw'
  93 +
  94 The 'raw' format shows the entire commit exactly as
  95 stored in the commit object.  Notably, the hashes are
  96 displayed in full, regardless of whether --abbrev or
  97 --no-abbrev are used, and 'parents' information show the
  98 true parent commits, without taking grafts or history
  99 simplification into account. Note that this format affects the way
 100 commits are displayed, but not the way the diff is shown e.g. with
 101 `git log --raw`. To get full object names in a raw diff format,
 102 use `--no-abbrev`.
 103
 104 * 'format:<string>'
 105 +
 106 The 'format:<string>' format allows you to specify which information
 107 you want to show. It works a little bit like printf format,
 108 with the notable exception that you get a newline with '%n'
 109 instead of '\n'.
 110 +
 111 E.g, 'format:"The author of %h was %an, %ar%nThe title was >>%s<<%n"'
 112 would show something like this:
 113 +
 114 -------
 115 The author of fe6e0ee was Junio C Hamano, 23 hours ago
 116 The title was >>t4119: test autocomputing -p<n> for traditional diff input.<<
 117
 118 -------
 119 +
 120 The placeholders are:
 121
 122 - Placeholders that expand to a single literal character:
 123 '%n':: newline
 124 '%%':: a raw '%'
 125 '%x00':: print a byte from a hex code
 126
 127 - Placeholders that affect formatting of later placeholders:
 128 '%Cred':: switch color to red
 129 '%Cgreen':: switch color to green
 130 '%Cblue':: switch color to blue
 131 '%Creset':: reset color
 132 '%C(...)':: color specification, as described under Values in the
 133             "CONFIGURATION FILE" section of linkgit:git-config[1].  By
 134             default, colors are shown only when enabled for log output
 135             (by `color.diff`, `color.ui`, or `--color`, and respecting
 136             the `auto` settings of the former if we are going to a
 137             terminal). `%C(auto,...)` is accepted as a historical
 138             synonym for the default (e.g., `%C(auto,red)`). Specifying
 139             `%C(always,...)` will show the colors even when color is
 140             not otherwise enabled (though consider just using
 141             `--color=always` to enable color for the whole output,
 142             including this format and anything else git might color).
 143             `auto` alone (i.e. `%C(auto)`) will turn on auto coloring
 144             on the next placeholders until the color is switched
 145             again.
 146 '%m':: left (`<`), right (`>`) or boundary (`-`) mark
 147 '%w([<w>[,<i1>[,<i2>]]])':: switch line wrapping, like the -w option of
 148                             linkgit:git-shortlog[1].
 149 '%<(<N>[,trunc|ltrunc|mtrunc])':: make the next placeholder take at
 150                                   least N columns, padding spaces on
 151                                   the right if necessary.  Optionally
 152                                   truncate at the beginning (ltrunc),
 153                                   the middle (mtrunc) or the end
 154                                   (trunc) if the output is longer than
 155                                   N columns.  Note that truncating
 156                                   only works correctly with N >= 2.
 157 '%<|(<N>)':: make the next placeholder take at least until Nth
 158              columns, padding spaces on the right if necessary
 159 '%>(<N>)', '%>|(<N>)':: similar to '%<(<N>)', '%<|(<N>)' respectively,
 160                         but padding spaces on the left
 161 '%>>(<N>)', '%>>|(<N>)':: similar to '%>(<N>)', '%>|(<N>)'
 162                           respectively, except that if the next
 163                           placeholder takes more spaces than given and
 164                           there are spaces on its left, use those
 165                           spaces
 166 '%><(<N>)', '%><|(<N>)':: similar to '%<(<N>)', '%<|(<N>)'
 167                           respectively, but padding both sides
 168                           (i.e. the text is centered)
 169
 170 - Placeholders that expand to information extracted from the commit:
 171 '%H':: commit hash
 172 '%h':: abbreviated commit hash
 173 '%T':: tree hash
 174 '%t':: abbreviated tree hash
 175 '%P':: parent hashes
 176 '%p':: abbreviated parent hashes
 177 '%an':: author name
 178 '%aN':: author name (respecting .mailmap, see linkgit:git-shortlog[1]
 179         or linkgit:git-blame[1])
 180 '%ae':: author email
 181 '%aE':: author email (respecting .mailmap, see linkgit:git-shortlog[1]
 182         or linkgit:git-blame[1])
 183 '%al':: author email local-part (the part before the '@' sign)
 184 '%aL':: author local-part (see '%al') respecting .mailmap, see
 185         linkgit:git-shortlog[1] or linkgit:git-blame[1])
 186 '%ad':: author date (format respects --date= option)
 187 '%aD':: author date, RFC2822 style
 188 '%ar':: author date, relative
 189 '%at':: author date, UNIX timestamp
 190 '%ai':: author date, ISO 8601-like format
 191 '%aI':: author date, strict ISO 8601 format
 192 '%as':: author date, short format (`YYYY-MM-DD`)
 193 '%cn':: committer name
 194 '%cN':: committer name (respecting .mailmap, see
 195         linkgit:git-shortlog[1] or linkgit:git-blame[1])
 196 '%ce':: committer email
 197 '%cE':: committer email (respecting .mailmap, see
 198         linkgit:git-shortlog[1] or linkgit:git-blame[1])
 199 '%cl':: committer email local-part (the part before the '@' sign)
 200 '%cL':: committer local-part (see '%cl') respecting .mailmap, see
 201         linkgit:git-shortlog[1] or linkgit:git-blame[1])
 202 '%cd':: committer date (format respects --date= option)
 203 '%cD':: committer date, RFC2822 style
 204 '%cr':: committer date, relative
 205 '%ct':: committer date, UNIX timestamp
 206 '%ci':: committer date, ISO 8601-like format
 207 '%cI':: committer date, strict ISO 8601 format
 208 '%cs':: committer date, short format (`YYYY-MM-DD`)
 209 '%d':: ref names, like the --decorate option of linkgit:git-log[1]
 210 '%D':: ref names without the " (", ")" wrapping.
 211 '%S':: ref name given on the command line by which the commit was reached
 212        (like `git log --source`), only works with `git log`
 213 '%e':: encoding
 214 '%s':: subject
 215 '%f':: sanitized subject line, suitable for a filename
 216 '%b':: body
 217 '%B':: raw body (unwrapped subject and body)
 218 ifndef::git-rev-list[]
 219 '%N':: commit notes
 220 endif::git-rev-list[]
 221 '%GG':: raw verification message from GPG for a signed commit
 222 '%G?':: show "G" for a good (valid) signature,
 223         "B" for a bad signature,
 224         "U" for a good signature with unknown validity,
 225         "X" for a good signature that has expired,
 226         "Y" for a good signature made by an expired key,
 227         "R" for a good signature made by a revoked key,
 228         "E" if the signature cannot be checked (e.g. missing key)
 229         and "N" for no signature
 230 '%GS':: show the name of the signer for a signed commit
 231 '%GK':: show the key used to sign a signed commit
 232 '%GF':: show the fingerprint of the key used to sign a signed commit
 233 '%GP':: show the fingerprint of the primary key whose subkey was used
 234         to sign a signed commit
 235 '%GT':: show the trust level for the key used to sign a signed commit
 236 '%gD':: reflog selector, e.g., `refs/stash@{1}` or `refs/stash@{2
 237         minutes ago}`; the format follows the rules described for the
 238         `-g` option. The portion before the `@` is the refname as
 239         given on the command line (so `git log -g refs/heads/master`
 240         would yield `refs/heads/master@{0}`).
 241 '%gd':: shortened reflog selector; same as `%gD`, but the refname
 242         portion is shortened for human readability (so
 243         `refs/heads/master` becomes just `master`).
 244 '%gn':: reflog identity name
 245 '%gN':: reflog identity name (respecting .mailmap, see
 246         linkgit:git-shortlog[1] or linkgit:git-blame[1])
 247 '%ge':: reflog identity email
 248 '%gE':: reflog identity email (respecting .mailmap, see
 249         linkgit:git-shortlog[1] or linkgit:git-blame[1])
 250 '%gs':: reflog subject
 251 '%(trailers[:options])':: display the trailers of the body as
 252                           interpreted by
 253                           linkgit:git-interpret-trailers[1]. The
 254                           `trailers` string may be followed by a colon
 255                           and zero or more comma-separated options:
 256 ** 'key=<K>': only show trailers with specified key. Matching is done
 257    case-insensitively and trailing colon is optional. If option is
 258    given multiple times trailer lines matching any of the keys are
 259    shown. This option automatically enables the `only` option so that
 260    non-trailer lines in the trailer block are hidden. If that is not
 261    desired it can be disabled with `only=false`.  E.g.,
 262    `%(trailers:key=Reviewed-by)` shows trailer lines with key
 263    `Reviewed-by`.
 264 ** 'only[=val]': select whether non-trailer lines from the trailer
 265    block should be included. The `only` keyword may optionally be
 266    followed by an equal sign and one of `true`, `on`, `yes` to omit or
 267    `false`, `off`, `no` to show the non-trailer lines. If option is
 268    given without value it is enabled. If given multiple times the last
 269    value is used.
 270 ** 'separator=<SEP>': specify a separator inserted between trailer
 271    lines. When this option is not given each trailer line is
 272    terminated with a line feed character. The string SEP may contain
 273    the literal formatting codes described above. To use comma as
 274    separator one must use `%x2C` as it would otherwise be parsed as
 275    next option. If separator option is given multiple times only the
 276    last one is used. E.g., `%(trailers:key=Ticket,separator=%x2C )`
 277    shows all trailer lines whose key is "Ticket" separated by a comma
 278    and a space.
 279 ** 'unfold[=val]': make it behave as if interpret-trailer's `--unfold`
 280    option was given. In same way as to for `only` it can be followed
 281    by an equal sign and explicit value. E.g.,
 282    `%(trailers:only,unfold=true)` unfolds and shows all trailer lines.
 283 ** 'valueonly[=val]': skip over the key part of the trailer line and only
 284    show the value part. Also this optionally allows explicit value.
 285
 286 NOTE: Some placeholders may depend on other options given to the
 287 revision traversal engine. For example, the `%g*` reflog options will
 288 insert an empty string unless we are traversing reflog entries (e.g., by
 289 `git log -g`). The `%d` and `%D` placeholders will use the "short"
 290 decoration format if `--decorate` was not already provided on the command
 291 line.
 292
 293 If you add a `+` (plus sign) after '%' of a placeholder, a line-feed
 294 is inserted immediately before the expansion if and only if the
 295 placeholder expands to a non-empty string.
 296
 297 If you add a `-` (minus sign) after '%' of a placeholder, all consecutive
 298 line-feeds immediately preceding the expansion are deleted if and only if the
 299 placeholder expands to an empty string.
 300
 301 If you add a ` ` (space) after '%' of a placeholder, a space
 302 is inserted immediately before the expansion if and only if the
 303 placeholder expands to a non-empty string.
 304
 305 * 'tformat:'
 306 +
 307 The 'tformat:' format works exactly like 'format:', except that it
 308 provides "terminator" semantics instead of "separator" semantics. In
 309 other words, each commit has the message terminator character (usually a
 310 newline) appended, rather than a separator placed between entries.
 311 This means that the final entry of a single-line format will be properly
 312 terminated with a new line, just as the "oneline" format does.
 313 For example:
 314 +
 315 ---------------------
 316 $ git log -2 --pretty=format:%h 4da45bef \
 317   | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
 318 4da45be
 319 7134973 -- NO NEWLINE
 320
 321 $ git log -2 --pretty=tformat:%h 4da45bef \
 322   | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
 323 4da45be
 324 7134973
 325 ---------------------
 326 +
 327 In addition, any unrecognized string that has a `%` in it is interpreted
 328 as if it has `tformat:` in front of it.  For example, these two are
 329 equivalent:
 330 +
 331 ---------------------
 332 $ git log -2 --pretty=tformat:%h 4da45bef
 333 $ git log -2 --pretty=%h 4da45bef
 334 ---------------------
