2020-09-27shortlog: allow multiple groups to be specifiedLibravatar Jeff King1-5/+5
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.

2020-09-27shortlog: match commit trailers with --groupLibravatar Jeff King1-0/+2
If a project uses commit trailers, this patch lets you use shortlog to see who is performing each action. For example, running: git shortlog -ns --group=trailer:reviewed-by in git.git shows who has reviewed. You can even use a custom format to see things like who has helped whom: git shortlog --format="...helped %an (%ad)" \ --group=trailer:helped-by Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-09-27shortlog: add grouping optionLibravatar Jeff King1-1/+5
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>
2018-08-15Add missing includes and forward declarationsLibravatar Elijah Newren1-0/+2
I looped over the toplevel header files, creating a temporary two-line C program for each consisting of #include "git-compat-util.h" #include $HEADER This patch is the result of manually fixing errors in compiling those tiny programs.

2016-12-15shortlog: group by committer informationLibravatar Linus Torvalds1-0/+1
In some situations you may want to group the commits not by author, but by committer instead. For example, when I just wanted to look up what I'm still missing from linux-next in the current merge window, I don't care so much about who wrote a patch, as what git tree it came from, which generally boils down to "who committed it". So make git shortlog take a "-c" or "--committer" option to switch grouping to that. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-07-21Rename path_list to string_listLibravatar Johannes Schindelin1-3/+3
The name path_list was correct for the first usage of that data structure, but it really is a general-purpose string list. $ perl -i -pe 's/path-list/string-list/g' $(git grep -l path-list) $ perl -i -pe 's/path_list/string_list/g' $(git grep -l path_list) $ git mv path-list.h string-list.h $ git mv path-list.c string-list.c $ perl -i -pe 's/has_path/has_string/g' $(git grep -l has_path) $ perl -i -pe 's/path/string/g' string-list.[ch] $ git mv Documentation/technical/api-path-list.txt \ Documentation/technical/api-string-list.txt $ perl -i -pe 's/strdup_paths/strdup_strings/g' $(git grep -l strdup_paths) ... and then fix all users of string-list to access the member "string" instead of "path". Documentation/technical/api-string-list.txt needed some rewrapping, too. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-07-15shortlog: support --pretty=format: optionLibravatar Johannes Schindelin1-0/+1
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.

2008-02-25Add API access to shortlogLibravatar Daniel Barkalow1-0/+26
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>
