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[='']:: + + Pretty print the contents of the commit logs in a given format, + where '' 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.
