Subject: [PATCH v1 0/5] git log: configurable default format for merge diffs
Date: Sat, 10 Apr 2021 20:16:52 +0300 [thread overview]
Message-ID: <20210410171657.20159-1-sorganov@gmail.com> (raw)
In-Reply-To: <20210407225608.14611-1-sorganov@gmail.com>
These patches introduce capability to configure the default format of
output of diffs for merge commits by means of new log.diffMerges
configuration variable. The default format is then used by -m,
--diff-merges=m, and new --diff-merges=default options.
In particular,
git config log.diffMerges first-parent
will change -m option format from "separate" to "first-parent" that
will in turn cause, say,
git show -m <merge_commit>
to output diff to the first parent only, instead of appending
typically large and surprising diff to the second parent at the end of
the output.
Updates in v1:
* Renamed abbreviated value "def" to full "default"
* Fixed tests to use "test_config" instead of "git config"
* Meld all "git config" changes into single commit that includes
code, documentation, and tests, as they are mutually
interdependent.
Sergey Organov (5):
diff-merges: introduce --diff-merges=default
diff-merges: refactor set_diff_merges()
diff-merges: adapt -m to enable default diff format
diff-merges: introduce log.diffMerges config variable
doc/diff-options: document new --diff-merges features
