An attempted facelift to the neglected git-rev-list manpage. One
question if I may, the diff-related -r and -t options, how are they
supposed to work?

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. "git-rev-list foo bar {caret}baz" thus
+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>.
+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:
-Another special notation is <commit1>...<commit2> which is useful for
-merges. The resulting set of commits is the symmetric difference
+-----------------------------------------------------------------------
+ $ 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
-------------
+-----------------------------------------------------------------------
+ $ 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
-------
---pretty::
- Print the contents of the commit changesets in human-readable form.
+
+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.
+
+ Print the contents of the commit in raw-format; each record is
+ separated with a NUL character.
--parents::
+
Print the parents of the commit.
---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'".
+Diff Formatting
+~~~~~~~~~~~~~~~
---objects-edge::
- Similar to `--objects`, but also print the IDs of
- excluded commits prefixed with a `-` character. This is
- used by `git-pack-objects` to build 'thin' pack, which
- records objects in deltified form based on objects
- contained in these excluded commits to reduce network
- traffic.
+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.
---unpacked::
- Only useful with `--objects`; print the object IDs that
- are not in packs.
+-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'::
---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 {caret}bar {caret}baz' outputs 'midpoint', the output
- of 'git-rev-list foo {caret}midpoint' and 'git-rev-list midpoint
- {caret}bar {caret}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.
+--since='date', --after='date'::
+
+ Show commits more recent than a specific date.
+
+--until='date', --before='date'::
---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.
+ Show commits older than a specific date.
+
+--max-age='timestamp', --min-age='timestamp'::
+
+ Limit the commits output to specified time range.
--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`.
+
+ 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 `$GIT_DIR/refs/` are
- listed on the command line as <commit>.
---topo-order::
- By default, the commits are shown in reverse
- chronological order. This option makes them appear in
- topological order (i.e. descendant commits are shown
- before their parents).
+ Pretend as if all the refs in `$GIT_DIR/refs/` are listed on the
+ command line as '<commit>'.
--merge::
+
After a failed merge, show refs that touch files having a
conflict and don't exist on all heads to merge.
---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".
+--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.
