post-tag hook?

post-tag hook?

Hi,

Is there a way to run a command every time a message gets tagged?

I would like to keep in sync tags and folder names. The problem is that it
requires a full scan of the notmuch db, which is slow. If I was running
this script only on messages that got retagged since like run of my script
it would be much faster. Unfortunately I don't find a way to mark/save
these messages in a notmuch hook.

I found an old thread from 2012, where somebody mentionned they implemented
a post-tag hook. Was this ever integrated?

Cheers,
Christophe-Marie

I think the concensus was that we would rather go for tag "mtimes"
as started with the series

Unfortunately nobody yet found time to finish that series.

Ah! Clever, I like the idea of using mtime.

Hi,

for what it's worth, you can simulate a post-tag hook in a somewhat ugly
way by putting a script called "notmuch" in front of the notmuch binary
in your PATH. The script can then call the original notmuch binary as
usual, inspect the first argument, and, if it's "tag", invoke your
script afterwards. I.e. something like this:

-------------------------------------
#!/bin/sh

/usr/bin/notmuch $@
retval=$?
if [[ "$1" == "tag" ]]; then
   shift 1
   your-script $@
fi
exit $retval
-------------------------------------

On a more general note, I'm experimenting with a way to synchronize tags
by logging and replaying tag commands performed on other machines and
for such an approach a post-tag hook would help. It seems to me that not
all use cases for a post-tag hook can be handled as nicely with mtimes.

Best regards,
Daniel
