I think something like this in .git/hooks/applypatch-msg will work: . git-sh-setup perl -pi -e 's|^Message-Id:\s*<?([^>]+)>?$|Link: https://patch.msgid.link/$1|g;' "$1" test -x "$GIT_DIR/hooks/commit-msg" && exec "$GIT_DIR/hooks/commit-msg" ${1+"$@"} : but I didn't actually try.

These sort of links are part of the prose, they're not something a script can download and make any sense of. I see some existing usage of the above style, but equally there's lots of examples of footnote-style links without the Link: tag, eg: commit 40b561e501768ef24673d0e1d731a7b9b1bc6709 Merge: d9f843fbd45e 31611cc8faa0 Author: Arnd Bergmann <arnd@arndb.de> Date: Mon Apr 29 22:29:44 2024 +0200 Merge tag 'tee-ts-for-v6.10' of https://git.linaro.org/people/jens.wiklander/linux-tee into soc/drivers TEE driver for Trusted Services This introduces a TEE driver for Trusted Services [1].

It's a good point. If we're formalizing this, why not literally use markdown instead? (I guess the answer is that out-of-line links/footnotes isn't standardized.) Playing devil's advocate, outside of the kernel, these are the two most common styles I've seen: Foo[1] ... [1]: https://.... and Bar[^1] ... [^1] https://... Personally, I only want to have a single official way to do this, and don't care much what it is. I have a minor preference for what you've described: Baz[1] ... [1] https://... -Kees

It's safe to ignore such complaints.

We have used '#' for ages for adding comments to by: tags. I'm surprised that it's not documented.

I thought it was documented, but either I was wrong or can't find it. But I found process/5.Posting.rst, which provides this example: Link: https://example.com/somewhere.html optional-other-stuff So no "# " there. So to avoid inconsistencies I guess this should not be applied, unless that document is changed as well. Ciao, Thorsten

Currently, there are two mechanisms to provide comments with trailers: 1: | Trailer-name: trailer-content # trailer-comment 2: | Trailer-name: trailer-content | [trailer-comment] For the sake of consistency, all trailers, including Link, should use one of these two mechanisms for "optional-other-stuff". -K
