  29DESCRIPTION
  30-----------
  31
  32Lists commit objects in reverse chronological order starting at the
  33given commit(s), taking ancestry relationship into account.  This is
  34useful to produce human-readable log output.
  35
  36Commits which are stated with a preceding '{caret}' cause listing to
  37stop at that point. Their parents are implied. Thus the following
  38command:
  39
  40-----------------------------------------------------------------------
  41        $ git-rev-list foo bar ^baz
  42-----------------------------------------------------------------------
  43
  44means "list all the commits which are included in 'foo' and 'bar', but
  45not in 'baz'".
  46
  47A special notation "'<commit1>'..'<commit2>'" can be used as a
  48short-hand for "{caret}'<commit1>' '<commit2>'". For example, either of
  49the following may be used interchangeably:
  50
  51-----------------------------------------------------------------------
  52        $ git-rev-list origin..HEAD
  53        $ git-rev-list HEAD ^origin
  54-----------------------------------------------------------------------
  55
  56Another special notation is "'<commit1>'...'<commit2>'" which is useful
  57for merges.  The resulting set of commits is the symmetric difference
  58between the two operands.  The following two commands are equivalent:
  59
  60-----------------------------------------------------------------------
  61        $ git-rev-list A B --not $(git-merge-base --all A B)
  62        $ git-rev-list A...B
  63-----------------------------------------------------------------------
  64
  65gitlink:git-rev-list[1] is a very essential git program, since it
  66provides the ability to build and traverse commit ancestry graphs. For
  67this reason, it has a lot of different options that enables it to be
  68used by commands as different as gitlink:git-bisect[1] and
  69gitlink:git-repack[1].
  70
  71OPTIONS
  72-------
  73
  74Commit Formatting
  75~~~~~~~~~~~~~~~~~
  76
  77Using these options, gitlink:git-rev-list[1] will act similar to the
  78more specialized family of commit log tools: gitlink:git-log[1],
  79gitlink:git-show[1], and gitlink:git-whatchanged[1]
  80
  81--pretty[='<format>']::
  82
  83        Pretty print the contents of the commit logs in a given format,
  84        where '<format>' can be one of 'raw', 'medium', 'short', 'full',
  85        and 'oneline'. When left out the format default to 'medium'.
  86
  87--relative-date::
  88
  89        Show dates relative to the current time, e.g. "2 hours ago".
  90        Only takes effect for dates shown in human-readable format, such
  91        as when using "--pretty".
  92
  93--header::
  94
  95        Print the contents of the commit in raw-format; each record is
  96        separated with a NUL character.
  97
  98--parents::
  99
 100        Print the parents of the commit.
 101
 102Diff Formatting
 103~~~~~~~~~~~~~~~
 104
 105Below are listed options that control the formatting of diff output.
 106Some of them are specific to gitlink:git-rev-list[1], however other diff
 107options may be given. See gitlink:git-diff-files[1] for more options.
 108
 109-c::
 110
 111        This flag changes the way a merge commit is displayed.  It shows
 112        the differences from each of the parents to the merge result
 113        simultaneously instead of showing pairwise diff between a parent
 114        and the result one at a time. Furthermore, it lists only files
 115        which were modified from all parents.
 116
 117--cc::
 118
 119        This flag implies the '-c' options and further compresses the
 120        patch output by omitting hunks that show differences from only
 121        one parent, or show the same change from all but one parent for
 122        an Octopus merge.
 123
 124-r::
 125
 126        Show recursive diffs.
 127
 128-t::
 129
 130        Show the tree objects in the diff output. This implies '-r'.
 131
 132Commit Limiting
 133~~~~~~~~~~~~~~~
 134
 135Besides specifying a range of commits that should be listed using the
 136special notations explained in the description, additional commit
 137limiting may be applied.
 138
 139--
 140
 141-n 'number', --max-count='number'::
 142
 143        Limit the number of commits output.
 144
 145--since='date', --after='date'::
 146
 147        Show commits more recent than a specific date.
 148
 149--until='date', --before='date'::
 150
 151        Show commits older than a specific date.
 152
 153--max-age='timestamp', --min-age='timestamp'::
 154
 155        Limit the commits output to specified time range.
 156
 157--remove-empty::
 158
 159        Stop when a given path disappears from the tree.
 160
 161--no-merges::
 162
 163        Do not print commits with more than one parent.
 164
 165--not::
 166
 167        Reverses the meaning of the '{caret}' prefix (or lack thereof)
 168        for all following revision specifiers, up to the next '--not'.
 169
 170--all::
 171
 172        Pretend as if all the refs in `$GIT_DIR/refs/` are listed on the
 173        command line as '<commit>'.
 174
 175--stdin::
 176
 177        In addition to the '<commit>' listed on the command
 178        line, read them from the standard input.
 179
 180--merge::
 181
 182        After a failed merge, show refs that touch files having a
 183        conflict and don't exist on all heads to merge.
 184
 185--boundary::
 186
 187        Output uninteresting commits at the boundary, which are usually
 188        not shown.
 189
 190--dense, --sparse::
 191
 192When optional paths are given, the default behaviour ('--dense') is to
 193only output commits that changes at least one of them, and also ignore
 194merges that do not touch the given paths.
 195
 196Use the '--sparse' flag to makes the command output all eligible commits
 197(still subject to count and age limitation), but apply merge
 198simplification nevertheless.
 199
 200--bisect::
 201
 202Limit output to the one commit object which is roughly halfway between
 203the included and excluded commits. Thus, if
 204
 205-----------------------------------------------------------------------
 206        $ git-rev-list --bisect foo ^bar ^baz
 207-----------------------------------------------------------------------
 208
 209outputs 'midpoint', the output of the two commands
 210
 211-----------------------------------------------------------------------
 212        $ git-rev-list foo ^midpoint
 213        $ git-rev-list midpoint ^bar ^baz
 214-----------------------------------------------------------------------
 215
 216would be of roughly the same length.  Finding the change which
 217introduces a regression is thus reduced to a binary search: repeatedly
 218generate and test new 'midpoint's until the commit chain is of length
 219one.
 220
 221--
 222
 223Commit Ordering
 224~~~~~~~~~~~~~~~
 225
 226By default, the commits are shown in reverse chronological order.
 227
 228--topo-order::
 229
 230        This option makes them appear in topological order (i.e.
 231        descendant commits are shown before their parents).
 232
 233--date-order::
 234
 235        This option is similar to '--topo-order' in the sense that no
 236        parent comes before all of its children, but otherwise things
 237        are still ordered in the commit timestamp order.
 238
 239Object Traversal
 240~~~~~~~~~~~~~~~~
 241
 242These options are mostly targeted for packing of git repositories.
 243
 244--objects::
 245
 246        Print the object IDs of any object referenced by the listed
 247        commits.  'git-rev-list --objects foo ^bar' thus means "send me
 248        all object IDs which I need to download if I have the commit
 249        object 'bar', but not 'foo'".
 250
 251--objects-edge::
 252
 253        Similar to '--objects', but also print the IDs of excluded
 254        commits prefixed with a "-" character.  This is used by
 255        gitlink:git-pack-objects[1] to build "thin" pack, which records
 256        objects in deltified form based on objects contained in these
 257        excluded commits to reduce network traffic.
 258
 259--unpacked::
 260
 261        Only useful with '--objects'; print the object IDs that are not
 262        in packs.
