From be0ef6fcd2379ea3dc1569d6d8c360d6d59d031f Mon Sep 17 00:00:00 2001 From: Mirko Faina Date: Sat, 7 Mar 2026 00:34:43 +0100 Subject: format-patch: add commitListFormat config Using "--cover-letter" we can tell format-patch to generate a cover letter, in this cover letter there's a list of commits included in the patch series and the format is specified by the "--cover-letter-format" option. Would be useful if this format could be configured from the config file instead of always needing to pass it from the command line. Teach format-patch how to read the format spec for the cover letter from the config files. The variable it should look for is called format.commitListFormat. Possible values: - commitListFormat is set but no string is passed: it will default to "[%(count)/%(total)] %s" - if a string is passed: will use it as a format spec. Note that this is either "shortlog" or a format spec prefixed by "log:" e.g."log:%s (%an)" - if commitListFormat is not set: it will default to the shortlog format.
