Hello, What would be the proper way of automatically tagging messages whose file has been renamed?
My use case is the following: In order to have some synchronization of tags between several machines, I use folders on the IMAP server. The idea is simply that messages tagged "foo" are actually moved to a folder "foo". The same applies to the "inbox" tag, and as an exception, messages in a folder named "saved" are those with no tags. Of course this excludes having several tags on a given message (except for the special tags like "unread" and "signed"), but it does fit my needs for now. The post-new hook says this: #!/bin/sh for FOLDER in * do case $FOLDER in INBOX) TAG=inbox ;; Drafts) TAG=draft ;; Trash) TAG=killed ;; saved) continue ;; *) TAG=$FOLDER esac notmuch tag -$TAG -- tag:$TAG not folder:$FOLDER notmuch tag +$TAG -- folder:$FOLDER not tag:$TAG done It does work but it is rather slow: 8 seconds, for a collection of 16000 messages. I can live with that but it does involve browsing the whole collection for each tag. Having a tag on all moved messages, like for the new ones, would dramatically improve this process. Besides, the "folder:" prefix is not an exact search, so the above does not work well if one folder name is part of another, like if I had a folder "bar" and a folder "foo.bar". Is there a way around this? I have another script called "pre-sync" that moves messages to folders according to their tags. This one is called before offlineimap does the full actual synchronization (calling notmuch new after that). I welcome any comments on my usage pattern, as there may well be better approaches I didn't think of... -- Emmanuel
