   1PRETTY FORMATS
   2--------------
   3
   4If the commit is a merge, and if the pretty-format
   5is not 'oneline', 'email' or 'raw', an additional line is
   6inserted before the 'Author:' line.  This line begins with
   7"Merge: " and the sha1s of ancestral commits are printed,
   8separated by spaces.  Note that the listed commits may not
   9necessarily be the list of the *direct* parent commits if you
  10have limited your view of history: for example, if you are
  11only interested in changes related to a certain directory or
  12file.
  13
  14There are several built-in formats, and you can define
  15additional formats by setting a pretty.<name>
  16config option to either another format name, or a
  17'format:' string, as described below (see
  18linkgit:git-config[1]). Here are the details of the
  19built-in formats:
  20
  21* 'oneline'
  22
  23          <sha1> <title line>
  24+
  25This is designed to be as compact as possible.
  26
  27* 'short'
  28
  29          commit <sha1>
  30          Author: <author>
  31
  32              <title line>
  33
  34* 'medium'
  35
  36          commit <sha1>
  37          Author: <author>
  38          Date:   <author date>
  39
  40              <title line>
  41
  42              <full commit message>
  43
  44* 'full'
  45
  46          commit <sha1>
  47          Author: <author>
  48          Commit: <committer>
  49
  50              <title line>
  51
  52              <full commit message>
  53
  54* 'fuller'
  55
  56          commit <sha1>
  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* 'email'
  67
  68          From <sha1> <date>
  69          From: <author>
  70          Date: <author date>
  71          Subject: [PATCH] <title line>
  72
  73          <full commit message>
  74
  75* 'raw'
  76+
  77The 'raw' format shows the entire commit exactly as
  78stored in the commit object.  Notably, the SHA-1s are
  79displayed in full, regardless of whether --abbrev or
  80--no-abbrev are used, and 'parents' information show the
  81true parent commits, without taking grafts or history
  82simplification into account. Note that this format affects the way
  83commits are displayed, but not the way the diff is shown e.g. with
  84`git log --raw`. To get full object names in a raw diff format,
  85use `--no-abbrev`.
  86
  87* 'format:<string>'
  88+
  89The 'format:<string>' format allows you to specify which information
  90you want to show. It works a little bit like printf format,
  91with the notable exception that you get a newline with '%n'
  92instead of '\n'.
  93+
  94E.g, 'format:"The author of %h was %an, %ar%nThe title was >>%s<<%n"'
  95would show something like this:
  96+
  97-------
  98The author of fe6e0ee was Junio C Hamano, 23 hours ago
  99The title was >>t4119: test autocomputing -p<n> for traditional diff input.<<
 100
 101-------
 102+
 103The placeholders are:
 104
 105- '%H': commit hash
 106- '%h': abbreviated commit hash
 107- '%T': tree hash
 108- '%t': abbreviated tree hash
 109- '%P': parent hashes
 110- '%p': abbreviated parent hashes
 111- '%an': author name
 112- '%aN': author name (respecting .mailmap, see linkgit:git-shortlog[1]
 113  or linkgit:git-blame[1])
 114- '%ae': author email
 115- '%aE': author email (respecting .mailmap, see
 116  linkgit:git-shortlog[1] or linkgit:git-blame[1])
 117- '%ad': author date (format respects --date= option)
 118- '%aD': author date, RFC2822 style
 119- '%ar': author date, relative
 120- '%at': author date, UNIX timestamp
 121- '%ai': author date, ISO 8601-like format
 122- '%aI': author date, strict ISO 8601 format
 123- '%cn': committer name
 124- '%cN': committer name (respecting .mailmap, see
 125  linkgit:git-shortlog[1] or linkgit:git-blame[1])
 126- '%ce': committer email
 127- '%cE': committer email (respecting .mailmap, see
 128  linkgit:git-shortlog[1] or linkgit:git-blame[1])
 129- '%cd': committer date (format respects --date= option)
 130- '%cD': committer date, RFC2822 style
 131- '%cr': committer date, relative
 132- '%ct': committer date, UNIX timestamp
 133- '%ci': committer date, ISO 8601-like format
 134- '%cI': committer date, strict ISO 8601 format
 135- '%d': ref names, like the --decorate option of linkgit:git-log[1]
 136- '%D': ref names without the " (", ")" wrapping.
 137- '%e': encoding
 138- '%s': subject
 139- '%f': sanitized subject line, suitable for a filename
 140- '%b': body
 141- '%B': raw body (unwrapped subject and body)
 142ifndef::git-rev-list[]
 143- '%N': commit notes
 144endif::git-rev-list[]
 145- '%GG': raw verification message from GPG for a signed commit
 146- '%G?': show "G" for a good (valid) signature,
 147  "B" for a bad signature,
 148  "U" for a good signature with unknown validity,
 149  "X" for a good signature that has expired,
 150  "Y" for a good signature made by an expired key,
 151  "R" for a good signature made by a revoked key,
 152  "E" if the signature cannot be checked (e.g. missing key)
 153  and "N" for no signature
 154- '%GS': show the name of the signer for a signed commit
 155- '%GK': show the key used to sign a signed commit
 156- '%gD': reflog selector, e.g., `refs/stash@{1}` or
 157  `refs/stash@{2 minutes ago`}; the format follows the rules described
 158  for the `-g` option. The portion before the `@` is the refname as
 159  given on the command line (so `git log -g refs/heads/master` would
 160  yield `refs/heads/master@{0}`).
 161- '%gd': shortened reflog selector; same as `%gD`, but the refname
 162  portion is shortened for human readability (so `refs/heads/master`
 163  becomes just `master`).
 164- '%gn': reflog identity name
 165- '%gN': reflog identity name (respecting .mailmap, see
 166  linkgit:git-shortlog[1] or linkgit:git-blame[1])
 167- '%ge': reflog identity email
 168- '%gE': reflog identity email (respecting .mailmap, see
 169  linkgit:git-shortlog[1] or linkgit:git-blame[1])
 170- '%gs': reflog subject
 171- '%Cred': switch color to red
 172- '%Cgreen': switch color to green
 173- '%Cblue': switch color to blue
 174- '%Creset': reset color
 175- '%C(...)': color specification, as described under Values in the
 176  "CONFIGURATION FILE" section of linkgit:git-config[1];
 177  adding `auto,` at the beginning (e.g. `%C(auto,red)`) will emit
 178  color only when colors are enabled for log output (by `color.diff`,
 179  `color.ui`, or `--color`, and respecting the `auto` settings of the
 180  former if we are going to a terminal). `auto` alone (i.e.
 181  `%C(auto)`) will turn on auto coloring on the next placeholders
 182  until the color is switched again.
 183- '%m': left (`<`), right (`>`) or boundary (`-`) mark
 184- '%n': newline
 185- '%%': a raw '%'
 186- '%x00': print a byte from a hex code
 187- '%w([<w>[,<i1>[,<i2>]]])': switch line wrapping, like the -w option of
 188  linkgit:git-shortlog[1].
 189- '%<(<N>[,trunc|ltrunc|mtrunc])': make the next placeholder take at
 190  least N columns, padding spaces on the right if necessary.
 191  Optionally truncate at the beginning (ltrunc), the middle (mtrunc)
 192  or the end (trunc) if the output is longer than N columns.
 193  Note that truncating only works correctly with N >= 2.
 194- '%<|(<N>)': make the next placeholder take at least until Nth
 195  columns, padding spaces on the right if necessary
 196- '%>(<N>)', '%>|(<N>)': similar to '%<(<N>)', '%<|(<N>)'
 197  respectively, but padding spaces on the left
 198- '%>>(<N>)', '%>>|(<N>)': similar to '%>(<N>)', '%>|(<N>)'
 199  respectively, except that if the next placeholder takes more spaces
 200  than given and there are spaces on its left, use those spaces
 201- '%><(<N>)', '%><|(<N>)': similar to '% <(<N>)', '%<|(<N>)'
 202  respectively, but padding both sides (i.e. the text is centered)
 203- %(trailers): display the trailers of the body as interpreted by
 204  linkgit:git-interpret-trailers[1]. If the `:only` option is given,
 205  omit non-trailer lines from the trailer block.  If the `:unfold`
 206  option is given, behave as if interpret-trailer's `--unfold` option
 207  was given. E.g., `%(trailers:only:unfold)` to do both.
 208
 209NOTE: Some placeholders may depend on other options given to the
 210revision traversal engine. For example, the `%g*` reflog options will
 211insert an empty string unless we are traversing reflog entries (e.g., by
 212`git log -g`). The `%d` and `%D` placeholders will use the "short"
 213decoration format if `--decorate` was not already provided on the command
 214line.
 215
 216If you add a `+` (plus sign) after '%' of a placeholder, a line-feed
 217is inserted immediately before the expansion if and only if the
 218placeholder expands to a non-empty string.
 219
 220If you add a `-` (minus sign) after '%' of a placeholder, all consecutive
 221line-feeds immediately preceding the expansion are deleted if and only if the
 222placeholder expands to an empty string.
 223
 224If you add a ` ` (space) after '%' of a placeholder, a space
 225is inserted immediately before the expansion if and only if the
 226placeholder expands to a non-empty string.
 227
 228* 'tformat:'
 229+
 230The 'tformat:' format works exactly like 'format:', except that it
 231provides "terminator" semantics instead of "separator" semantics. In
 232other words, each commit has the message terminator character (usually a
 233newline) appended, rather than a separator placed between entries.
 234This means that the final entry of a single-line format will be properly
 235terminated with a new line, just as the "oneline" format does.
 236For example:
 237+
 238---------------------
 239$ git log -2 --pretty=format:%h 4da45bef \
 240  | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
 2414da45be
 2427134973 -- NO NEWLINE
 243
 244$ git log -2 --pretty=tformat:%h 4da45bef \
 245  | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
 2464da45be
 2477134973
 248---------------------
 249+
 250In addition, any unrecognized string that has a `%` in it is interpreted
 251as if it has `tformat:` in front of it.  For example, these two are
 252equivalent:
 253+
 254---------------------
 255$ git log -2 --pretty=tformat:%h 4da45bef
 256$ git log -2 --pretty=%h 4da45bef
 257---------------------
