Add API access to shortlog Shortlog is gives a pretty simple API for cases where you're already identifying all of the individual commits. Make this available to other code instead of requiring them to use the revision API and command line. Signed-off-by: Daniel Barkalow <barkalow@iabervon.org>

shortlog: accept `--date`-related options Prepare for a future patch which will introduce arbitrary pretty formats via the `--group` argument. To allow additional customizability (for example, to support something like `git shortlog -s --group='%aD' --date='format:%Y-%m' ...` (which groups commits by the datestring 'YYYY-mm' according to author date), we must store off the `--date` parsed from calling `parse_revision_opt()`. Note that this also affects custom output `--format` strings in `git shortlog`. Though this is a behavior change, this is arguably fixing a long-standing bug (ie., that `--format` strings are not affected by `--date` specifiers as they should be).

shortlog: support --pretty=format: option With this patch, the user can override the default setting, to print the commit messages using a user format instead of the onelines of the commits. Example: $ git shortlog --pretty='format:%s (%h)' <commit>.. Note that shortlog will only respect a user format setting, as the other formats do not make much sense. Wished for by Andrew Morton.

shortlog: add grouping option In preparation for adding more grouping types, let's refactor the committer/author grouping code and add a user-facing option that binds them together. In particular: - the main option is now "--group", to make it clear that the various group types are mutually exclusive. The "--committer" option is an alias for "--group=committer". - we keep an enum rather than a binary flag, to prepare for more values - we prefer switch statements to ternary assignment, since other group types will need more custom code Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

shortlog: allow multiple groups to be specified Now that shortlog supports reading from trailers, it can be useful to combine counts from multiple trailers, or between trailers and authors. This can be done manually by post-processing the output from multiple runs, but it's non-trivial to make sure that each name/commit pair is counted only once. This patch teaches shortlog to accept multiple --group options on the command line, and pull data from all of them. That makes it possible to run: git shortlog -ns --group=author --group=trailer:co-authored-by to get a shortlog that counts authors and co-authors equally. The implementation is mostly straightforward. The "group" enum becomes a bitfield, and the trailer key becomes a list. I didn't bother implementing the multi-group semantics for reading from stdin. It would be possible to do, but the existing matching code makes it awkward, and I doubt anybody cares. The duplicate suppression we used for trailers now covers authors and committers as well (though in non-trailer single-group mode we can skip the hash insertion and lookup, since we only see one value per commit). There is one subtlety: we now care about the case when no group bit is set (in which case we default to showing the author). The caller in builtin/log.c needs to be adapted to ask explicitly for authors, rather than relying on shortlog_init(). It would be possible with some gymnastics to make this keep working as-is, but it's not worth it for a single caller.

shortlog: support arbitrary commit format `--group`s In addition to generating a shortlog based on committer, author, or the identity in one or more specified trailers, it can be useful to generate a shortlog based on an arbitrary commit format. This can be used, for example, to generate a distribution of commit activity over time, like so: $ git shortlog --group='%cd' --date='format:%Y-%m' -s v2.37.0.. 117 2022-06 274 2022-07 324 2022-08 263 2022-09 7 2022-10 Arbitrary commit formats can be used. In fact, `git shortlog`'s default behavior (to count by commit authors) can be emulated as follows: $ git shortlog --group='%aN <%aE>' ... and future patches will make the default behavior (as well as `--committer`, and `--group=trailer:<trailer>`) special cases of the more flexible `--group` option. Note also that the SHORTLOG_GROUP_FORMAT enum value is used only to designate that `--group:<format>` is in use when in stdin mode to declare that the combination is invalid.
