Hello On irc recently dme posted a patch notmuch-pick.el which provided a threaded message view in the emacs interface. I have added substantially to it and made some cli changes to support it better. See http://kanelephant.com/screen.png for a screenshot. It seems to be working well (although doubtless has bugs and lots of room for improvement). One important caveat is that it does call notmuch-show rather than notmuch-search so it can be slow. Viewing 10000 notmuch messages takes me 20 seconds with a warm cache and about a minute with a cold cache. Viewing million message searches in this fashion is not recommended! Note since I modify the notmuch-show.c backend this applies on top of Jani's show parsing patches id:"cover.1328558175.git.jani@nikula.org" The most important key bindings are as follows: 'z' enter a search to display in pick view (analogous to s; works in hello, search, show and pick mode). 'Z' displays the current search in pick mode (works in search and show mode) In pick mode: RET displays a message (splitting the current window), SPACE scrolls the message window and goes to next message when it reaches the end, 'b' scrolls the message window back, 'p', 'n' move to the next matching message, 'q' closes the message window (if open) or quits the pick view. 't' toggles whether to show the messages as a thread-tree structure or just as single messages, 'o' toggles the sort order. Most of the other commands I could think of work as I would expect (eg tagging, piping, help etc) Questions/thoughts and known bugs: Do people like the rough idea? At the moment there is some shared code with notmuch-show.el. This could be factored out: however, while this pick mode is WIP I don't think it is worth it. I have tried to keep the impact on the current parts of the emacs code and the command line interface fairly small. I will send the patches as 3 bits: one is the command-line support needed (i.e. changes to notmuch-show.c) one is the changes to the other emacs files and the final one is the notmuch-pick.el file itself. There are some things that need fixing: some of which are marked in the code. For example the highlighting (lowlighting?) of non-matching messages is hard-wired gray and should be a defcustom. The tags are not in a nice tag face and do not update automatically. There should be an option not to use the split-screen mode. Anyway I am already finding it useful: show a long thread, press 'Z' to see the thread structure nicely and then ... Best wishes Mark
