DESCRIPTION
-----------

Lists commit objects in reverse chronological order starting at the
given commit(s), taking ancestry relationship into account.  This is
useful to produce human-readable log output.

Commits which are stated with a preceding '{caret}' cause listing to
stop at that point. Their parents are implied. Thus the following
command:

-----------------------------------------------------------------------
        $ git-rev-list foo bar ^baz
-----------------------------------------------------------------------

means "list all the commits which are included in 'foo' and 'bar', but
not in 'baz'".

A special notation "'<commit1>'..'<commit2>'" can be used as a
short-hand for "{caret}'<commit1>' '<commit2>'". For example, either of
the following may be used interchangeably:

-----------------------------------------------------------------------
        $ git-rev-list origin..HEAD
        $ git-rev-list HEAD ^origin
-----------------------------------------------------------------------

Another special notation is "'<commit1>'...'<commit2>'" which is useful
for merges.  The resulting set of commits is the symmetric difference
between the two operands.  The following two commands are equivalent:

-----------------------------------------------------------------------
        $ git-rev-list A B --not $(git-merge-base --all A B)
        $ git-rev-list A...B
-----------------------------------------------------------------------

gitlink:git-rev-list[1] is a very essential git program, since it
provides the ability to build and traverse commit ancestry graphs. For
this reason, it has a lot of different options that enables it to be
used by commands as different as gitlink:git-bisect[1] and
gitlink:git-repack[1].

OPTIONS
-------

Commit Formatting
~~~~~~~~~~~~~~~~~

Using these options, gitlink:git-rev-list[1] will act similar to the
more specialized family of commit log tools: gitlink:git-log[1],
gitlink:git-show[1], and gitlink:git-whatchanged[1]

--pretty[='<format>']::

        Pretty print the contents of the commit logs in a given format,
        where '<format>' can be one of 'raw', 'medium', 'short', 'full',
        and 'oneline'. When left out the format default to 'medium'.

--relative-date::

        Show dates relative to the current time, e.g. "2 hours ago".
        Only takes effect for dates shown in human-readable format, such
        as when using "--pretty".

--header::

        Print the contents of the commit in raw-format; each record is
        separated with a NUL character.

--parents::

        Print the parents of the commit.

Diff Formatting
~~~~~~~~~~~~~~~

Below are listed options that control the formatting of diff output.
Some of them are specific to gitlink:git-rev-list[1], however other diff
options may be given. See gitlink:git-diff-files[1] for more options.

-c::

        This flag changes the way a merge commit is displayed.  It shows
        the differences from each of the parents to the merge result
        simultaneously instead of showing pairwise diff between a parent
        and the result one at a time. Furthermore, it lists only files
        which were modified from all parents.

--cc::

        This flag implies the '-c' options and further compresses the
        patch output by omitting hunks that show differences from only
        one parent, or show the same change from all but one parent for
        an Octopus merge.

-r::

        Show recursive diffs.

-t::

        Show the tree objects in the diff output. This implies '-r'.

Commit Limiting
~~~~~~~~~~~~~~~

Besides specifying a range of commits that should be listed using the
special notations explained in the description, additional commit
limiting may be applied.

--

-n 'number', --max-count='number'::

        Limit the number of commits output.

--since='date', --after='date'::

        Show commits more recent than a specific date.

--until='date', --before='date'::

        Show commits older than a specific date.

--max-age='timestamp', --min-age='timestamp'::

        Limit the commits output to specified time range.

--author='pattern', --committer='pattern'::

        Limit the commits output to ones with author/committer
        header lines that match the specified pattern.

--grep='pattern'::

        Limit the commits output to ones with log message that
        matches the specified pattern.

--remove-empty::

        Stop when a given path disappears from the tree.

--no-merges::

        Do not print commits with more than one parent.

--not::

        Reverses the meaning of the '{caret}' prefix (or lack thereof)
        for all following revision specifiers, up to the next '--not'.

--all::

        Pretend as if all the refs in `$GIT_DIR/refs/` are listed on the
        command line as '<commit>'.

--stdin::

        In addition to the '<commit>' listed on the command
        line, read them from the standard input.

--merge::

        After a failed merge, show refs that touch files having a
        conflict and don't exist on all heads to merge.

--boundary::

        Output uninteresting commits at the boundary, which are usually
        not shown.

--dense, --sparse::

When optional paths are given, the default behaviour ('--dense') is to
only output commits that changes at least one of them, and also ignore
merges that do not touch the given paths.

Use the '--sparse' flag to makes the command output all eligible commits
(still subject to count and age limitation), but apply merge
simplification nevertheless.

--bisect::

Limit output to the one commit object which is roughly halfway between
the included and excluded commits. Thus, if

-----------------------------------------------------------------------
        $ git-rev-list --bisect foo ^bar ^baz
-----------------------------------------------------------------------

outputs 'midpoint', the output of the two commands

-----------------------------------------------------------------------
        $ git-rev-list foo ^midpoint
        $ git-rev-list midpoint ^bar ^baz
-----------------------------------------------------------------------

would be of roughly the same length.  Finding the change which
introduces a regression is thus reduced to a binary search: repeatedly
generate and test new 'midpoint's until the commit chain is of length
one.

--

Commit Ordering
~~~~~~~~~~~~~~~

By default, the commits are shown in reverse chronological order.

--topo-order::

        This option makes them appear in topological order (i.e.
        descendant commits are shown before their parents).

--date-order::

        This option is similar to '--topo-order' in the sense that no
        parent comes before all of its children, but otherwise things
        are still ordered in the commit timestamp order.

Object Traversal
~~~~~~~~~~~~~~~~

These options are mostly targeted for packing of git repositories.

--objects::

        Print the object IDs of any object referenced by the listed
        commits.  'git-rev-list --objects foo ^bar' thus means "send me
        all object IDs which I need to download if I have the commit
        object 'bar', but not 'foo'".

--objects-edge::

        Similar to '--objects', but also print the IDs of excluded
        commits prefixed with a "-" character.  This is used by
        gitlink:git-pack-objects[1] to build "thin" pack, which records
        objects in deltified form based on objects contained in these
        excluded commits to reduce network traffic.

--unpacked::

        Only useful with '--objects'; print the object IDs that are not
        in packs.
