# [PATCH 1/1] get_maintainer.pl: add --cc option to produce comma separated list of emails 4 messages from 2026-03-19 to 2026-03-19. Participants: Jim Cromie, Joe Perches, jim.cromie@gmail.com.

It also does the same for --to and --bcc, in case get_maintainer can usefully distinguish who should get the to's from the cc's. cc: git@vger.kernel.org Signed-off-by: Jim Cromie --- scripts/get_maintainer.pl | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/scripts/get_maintainer.pl b/scripts/get_maintainer.pl index 4414194bedcf..6c9ca793fd6e 100755 --- a/scripts/get_maintainer.pl +++ b/scripts/get_maintainer.pl @@ -48,6 +48,7 @@ my $email_remove_duplicates = 1; my $email_use_mailmap = 1; my $output_multiline = 1; my $output_separator = ", "; +my $output_cc = 0; my $output_roles = 0; my $output_rolestats = 1; my $output_substatus = undef; @@ -265,6 +266,7 @@ if (!GetOptions( 'moderated!' => \$email_moderated_list, 's!' => \$email_subscriber_list, 'multiline!' => \$output_multiline, + 'cc!' => \$output_cc, 'roles!' => \$output_roles, 'rolestats!' => \$output_rolestats, 'separator=s' => \$output_separator, @@ -320,6 +322,15 @@ if (!defined $output_substatus) { $output_substatus = $email && $output_roles && -t STDOUT; } +if ($output_cc) { + $email_usename = 0; + $output_multiline = 0; + $output_separator = ","; + $output_rolestats = 0; + $output_roles = 0; + $output_substatus = 0; +} + if ($sections || $letters ne "") { $sections = 1; $email = 0; @@ -1096,6 +1107,7 @@ MAINTAINER field selection options: --bug => print bug reporting info if any Output type options: + --cc => print comma separated list of all emails --separator [, ] => separator for multiple entries on 1 line using --separator also sets --nomultiline if --separator is not [, ] --multiline => print 1 entry per line -- 2.53.0 ``` ## Joe Perches, 2026-03-19 16:13 Subject: Re: [PATCH 1/1] get_maintainer.pl: add --cc option to produce comma separated list of emails Message-ID: URL: https://gitlist.dev/e/b69406326eceb27f5973bc0ba55366438845a003.camel%40perches.com In-Reply-To: <20260319160633.1149562-1-jim.cromie@gmail.com> ``` On Thu, 2026-03-19 at 10:06 -0600, Jim Cromie wrote: > ˋˋˋ > This new option works as follows: > > git send-email --cc=$(scripts/get_maintainer.pl -cc 0*.patch) 0*.patch > > A complementary patch has been sent to [git@vger.kernel.org](mailto:git@vger.kernel.org), allowing: > > git send-email --cc=scripts/get_maintainer.pl 0*.patch I think this is not particularly useful.

Efficiency (One-Shot vs. Per-Patch): Unlike --cc-cmd, which runs once per patch file, this runs once for the entire series. For a large series or a slow script (like get_maintainer.pl), this is a performance win and avoids redundant processing. 2. Dry-Run Integrity: By integrating it into send-email, the script execution is part of the command's own logic. This ensures that --dry-run accurately reflects exactly what the script produced within the context of the mailing operation. 3. Argument Deduplication: It eliminates the "Double-entry" problem where you have to pass the patch list twice (once to the subshell and once to git send-email). This reduces the chance of a typo causing you to send patches to the wrong set of maintainers if the lists get out of sync. 4. Configuration Synergy: You can now set sendemail.cc = ./scripts/get_maintainer.pl in your .git/config. A shell wrapper can't easily override or augment the built-in recipient logic as cleanly as this does. That last point seems a clear win. Far less maintainer annoyance at not receiving the entire patchset. ``` ## Joe Perches, 2026-03-19 17:08 Subject: Re: [PATCH 1/1] get_maintainer.pl: add --cc option to produce comma separated list of emails Message-ID: <5d28fa8fda122093fcfcf6f948f67184c0c9018e.camel@perches.com> URL: https://gitlist.dev/e/5d28fa8fda122093fcfcf6f948f67184c0c9018e.camel%40perches.com In-Reply-To: ``` On Thu, 2026-03-19 at 10:56 -0600, jim.cromie@gmail.com wrote: > On Thu, Mar 19, 2026 at 10:14 AM Joe Perches <[joe@perches.com](mailto:joe@perches.com)> wrote: > > On Thu, 2026-03-19 at 10:06 -0600, Jim Cromie wrote: > > > This new option works as follows: > > > git send-email --cc=$(scripts/get_maintainer.pl -cc 0*.patch) 0*.patch > > I think this is not particularly useful. > > Just use a script.

That's not my experience. This _will_ cc disinterested parties when there's a cover letter for a large series. ```
