DESCRIPTION
-----------
Lists commit objects in reverse chronological order starting at the
-given commit, taking ancestry relationship into account. This is
+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. "git-rev-list foo bar {caret}baz" thus
+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>.
+
+
+OPTIONS
+-------
+--pretty::
+ Print the contents of the commit changesets in human-readable form.
+
+--header::
+ Print the contents of the commit in raw-format; each
+ record is separated with a NUL character.
+
+--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'".
+
+--unpacked::
+ Only useful with `--objects`; print the object IDs that
+ are not in packs.
+
+--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 'git-rev-list foo ^midpoint' and '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.
+
+--max-count::
+ Limit the number of commits output.
+
+--max-age=timestamp, --min-age=timestamp::
+ Limit the commits output to specified time range.
+
+--sparse::
+ When optional paths are given, the command outputs only
+ the commits that changes at least one of them, and also
+ ignores merges that do not touch the given paths. This
+ flag makes the command output all eligible commits
+ (still subject to count and age limitation), but apply
+ merge simplification nevertheless.
+
+--all::
+ Pretend as if all the refs in `$GIT_DIR/refs/` are
+ listed on the command line as <commit>.
+
+--topo-order::
+ By default, the commits are shown in reverse
+ chronological order. This option makes them appear in
+ topological order (i.e. descendant commits are shown
+ before their parents).
+
+--merge-order::
+ When specified the commit history is decomposed into a unique
+ sequence of minimal, non-linear epochs and maximal, linear epochs.
+ Non-linear epochs are then linearised by sorting them into merge
+ order, which is described below.
++
+Maximal, linear epochs correspond to periods of sequential development.
+Minimal, non-linear epochs correspond to periods of divergent development
+followed by a converging merge. The theory of epochs is described in more
+detail at
+link:http://blackcubes.dyndns.org/epoch/[http://blackcubes.dyndns.org/epoch/].
++
+The merge order for a non-linear epoch is defined as a linearisation for which
+the following invariants are true:
++
+ 1. if a commit P is reachable from commit N, commit P sorts after commit N
+ in the linearised list.
+ 2. if Pi and Pj are any two parents of a merge M (with i < j), then any
+ commit N, such that N is reachable from Pj but not reachable from Pi,
+ sorts before all commits reachable from Pi.
++
+Invariant 1 states that later commits appear before earlier commits they are
+derived from.
++
+Invariant 2 states that commits unique to "later" parents in a merge, appear
+before all commits from "earlier" parents of a merge.
+
+--show-breaks::
+ Each item of the list is output with a 2-character prefix consisting
+ of one of: (|), (^), (=) followed by a space.
++
+Commits marked with (=) represent the boundaries of minimal, non-linear epochs
+and correspond either to the start of a period of divergent development or to
+the end of such a period.
++
+Commits marked with (|) are direct parents of commits immediately preceding
+the marked commit in the list.
++
+Commits marked with (^) are not parents of the immediately preceding commit.
+These "breaks" represent necessary discontinuities implied by trying to
+represent an arbitrary DAG in a linear form.
++
+`--show-breaks` is only valid if `--merge-order` is also specified.
