Hello, The three patches I sent to the list a couple of minutes ago is another revision of the patches that I had sent earlier. The first two patches implement support for 'notmuch search-tags'. The last patch adds support for tag completion to notmuch.el using the new command. Right now 'notmuch search-tags' can only list all tags from the database, it does not support search-terms yet (i.e. it cannot list tags for a restricted set of messages or threads), but I am working on that feature and I'm gonna send another patch implementing that soon. I think sending more smaller incremental patches makes it easier to review them (and for me personally it is easier to keep them up-to-date on top of moving Carl's git repository). I considered implementing 'notmuch search --output=tags' (as we discussed in another email), but it turned out that: * Having 'notmuch search-tags' would be consistent with Carl's 'notmuch search-messages'. * 'notmuch search' supports other command line options (--first, --max-threads, --sort) and these would only work when the user uses the command to search for messages. They would probably be useless if we use the command to search for tags and messages (well, at least some of them). Which means we would have to let the user know in the documentation, or disable some of them based on the value of the --output command line parameter, etc etc... * 'notmuch search-tags' is easier on fingers than 'notmuch search --output=tags' :-). In any case, we should probably keep it consistent with other commands and because Carl submitted 'notmuch search-messages", I did the same for tags. I'd personally prefer to use different commands for different kinds of output rather than overloading 'notmuch search' with more command line options, but it's just a personal preference. I can change the patch again if we decide that we're going to overload 'notmuch search' rather than add more commands. Comments, ideas, and suggestions are welcome! -- Jan
