When I pull from a remote, the default commit message will be "Merge branch 'source-branch-name' of https://bitbucket.org/ repository-name into destination-branch-name". I'd like to configure git to omit the "of https://bitbucket.org/repository-name" part. How can I do that? Regards Jost ``` ## Junio C Hamano, 2021-03-24 20:01 Subject: Re: Configure default merge message Message-ID: URL: https://gitlist.dev/e/xmqqk0pwxqvt.fsf%40gitster.g In-Reply-To: ``` jost.schulte@tutanota.com writes: > Hello all, > > I'm using git mainly with BitBucket repositories.

IIRC, in that earlier discussion Linus said he used a prepare-commit-msg hook these days instead of repo-abbrev. And it should be able to handle this case, as well. Something like this seems to work for me: $ cat .git/hooks/prepare-commit-msg #!/bin/sh case "$2" in merge) perl -i -pe ' s{Merge (.*) of https://github.com/gitster/git}{Merge $1} ' "$1" ;; esac $ git pull https://github.com/gitster/git next [...] $ git log -1 --format=%s Merge branch 'next' -Peff ``` ## Ævar Arnfjörð Bjarmason, 2021-03-25 02:02 Subject: Re: Configure default merge message Message-ID: <87a6qsourb.fsf@evledraar.gmail.com> URL: https://gitlist.dev/e/87a6qsourb.fsf%40evledraar.gmail.com In-Reply-To: ``` On Wed, Mar 24 2021, Junio C Hamano wrote: > jost.schulte@tutanota.com writes: > >> Hello all, >> >> I'm using git mainly with BitBucket repositories.

Perhaps I'm using it incorrectly, but I don't see how that repo-abbrev feature ever resulted in the insertion of this munged content into the actual commit object. The shortlog examples of "..." in 4e168333 are of shortlog's output being modified on the fly. Not of them being inserted into commits. You can run "git merge" with "--log" which says it inserts "shortlog" output. So I thought that maybe lines that were not the first "Merge ... into" line in the message could have gotten munged in this way before my change. But I don't think that happened either, and reverting 4e168333 and doing a merge --log locally with e.g. "# repo-abbrev: branch" does not munge the string "branch" in either the subject or the body, it's retained, e.g.: commit 02c864e58da (HEAD) Merge: 353c73510dc c6d63de00ff Author: Ævar Arnfjörð Bjarmason Date: Thu Mar 25 03:00:21 2021 +0100 Merge branch 'to-merge' into HEAD * to-merge: Merge this branch blah blah That's because "merge" never used the munging. If you look at the code in 7595e2ee6ef (git-shortlog: make common repository prefix configurable with .mailmap, 2006-11-25) when this repo-abbrev feature was first added the "merge" would use builtin-fmt-merge-msg.c to format the "shortlog", which implemented its own function to do so, and didn't use the mailmap. As to Jost's question. I think the way to do this is to use fmt-merge-msg, see 2102440c17f (fmt-merge-msg -m to override merge title, 2010-08-17) for an example. That seems like it would also be simpler than Jeff King's suggestion in the side-thread in . ``` ## jost.schulte@tutanota.com, 2021-03-26 06:30 Subject: Re: Configure default merge message Message-ID: URL: https://gitlist.dev/e/MWhDYQt--3-2%40tutanota.com In-Reply-To: <87a6qsourb.fsf@evledraar.gmail.com> ``` Thank you for the detailed explanation.

Where can I see the commits > that you mention? [It's good practice on this mailing list not to top-post] 4e168333 is a commit in your copy of the git.git repository. The 02c864e58da, 353c73510dc and c6d63de00ff are just something that was part of a throwaway experiment I ran locally. I created two branches based on git.git's 238803cb409 (the commit before 4e168333), one added a repo-abbrev line to .mailmap, the other had a string in the subject/body that would match that repo-abbrev. So the merge shows that the "branch" string was not replaced with "...". ```
