From 3dc95e09e1355ebde472bd5be37aa7b29ef774d3 Mon Sep 17 00:00:00 2001 From: Taylor Blau Date: Mon, 24 Oct 2022 14:55:39 -0400 Subject: 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:`) special cases of the more flexible `--group` option. Note also that the SHORTLOG_GROUP_FORMAT enum value is used only to designate that `--group:` is in use when in stdin mode to declare that the combination is invalid.
