Hi, Today, I tried;
--8<---------------cut here---------------start------------->8--- $ git send-email --to=guix-patc...@gnu.org \ $(./etc/teams.scm cc-members origin/master HEAD) 0000-cover-letter.patch fatal: ambiguous argument 'some.em...@redacted.com"': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git <command> [<revision>...] -- [<file>...]' format-patch -o /tmp/pFSRbRNNoU --add-header="X-Debbugs-Cc: redac...@gmail.com" --add-header="X-Debbugs-Cc: redacted@email" [...]: command returned error: 128 $ ./etc/teams.scm cc-members origin/master HEAD --add-header="X-Debbugs-Cc: redacted@email" --add-header="X-Debbugs-Cc: redacted@email" ... --8<---------------cut here---------------end--------------->8--- You can see the command fails; this is because when using Bash command substitution $(), the quotes in the result are not interpreted and are thus part of the value (literals), which then gets split on white space. As a quick hacky fix, I tried removing the space and double quotes like: modified etc/teams.scm.in @@ -514,7 +514,7 @@ (define (cc . teams) "Return arguments for `git send-email' to notify the members of the given TEAMS when a patch is received by Debbugs." (format #true - "~{--add-header=\"X-Debbugs-Cc: ~a\"~^ ~}" + "~{--add-header=X-Debbugs-Cc:~a~^ ~}" (map person-email (delete-duplicates (append-map team-members teams) equal?)))) and sent a patch with that command: git send-email --to=guix-patc...@gnu.org \ $(./etc/teams.scm cc-members origin/master HEAD 0000-cover-letter.patch It created https://issues.guix.gnu.org/58812 with it, but I don't see any of the X-Debbugs-Cc headers. Mmmh. -- Thanks, Maxim
