I _have_ been thinking about and working +on this. This message summarizes my current thinking/plan. + +I'm not very enthusiastic about the about the several places this can +get out of sync + +1) config info in .notmuch-config can be out of sync with the "real +config" in the database. This part is only until the next run of +notmuch new, so it's not so bad. + +2) When the interpretation of maildir flags changes, there doesn't seem +to be a sensible way of retagging messages. + +Some others have objected to supporting a nonstandard extension used (I +think) only by dovecot. For me this is not so bad, as long as the code +required specifically for this is not too large / intrusive. + +So here are the pieces I think we need. + +a) some code in notmuch-new to sync flags a-z to a fixed set of tags + [1]. This soundspretty much the functionality you have now, although I + haven't really reviewed that part of the series. + +b) some code to update metadata directly from the CLI (notmuch + config/notmuch tag), probably using something like [2] as a back + end. This metadata maps the fixed tags like $maildir_flag_k to and + from some friendly format. + +c) The use of xapian field processors to translate e.g. a query + "tag:my-sensible-thing" into "tag:$maildir_flag_k". Optionally do the + reverse when returning lists of tags. FieldProcessors are only + available in Xapian 1.3.x, but apparently 1.3 series is nearing a + stable release, so it's a sane time to optionally depend on it. + I guess as a short term hack, this could be done by shell wrappers + (not something we'd ship, but it might make it usable for you). + +d) code to dump and restore the metadata as part of the normal dump + files. This is at least in progress [2]. + +In terms of how these changes relate to other goals + +b,d) have strong connects with allowing database level config. Among + other reasons this will help make bindings users less second class + citizens + + + c) has overlap with allowing date fields that are not ranges (among + other things). At least all the machinery to configure xapian 1.2 + versus 1.3, and the understanding how to use field processors, is + reusable. + +I'd understand perfectly if you prefer to rebase your simpler solution +on top of master, but if you want to keep working on this, then I guess +(a), (b), and (c) are all things you would work on. + +Probably (b) needs the library api from [2], which now that I start +typing this epic long message, I could split off from the dump/restore +stuff. In particular managing the config metadata only needs about half +of the LOC; the iterator is only needed for dump, I think. + +David + +[1]: eventually it might make sense to split the tags that are somehow +automatic from those that represent user choice. We already have this +issue with tag:encrypted and friends. + +[2]: id:1452394301-29499-1-git-send-email-david@tethera.net
