[PATCH 0/7] Port notmuch-show's x/X bindings to notmuch-tree

[William Casarin]

These patches bring notmuch-tree more in line with the user experience
of notmuch-show by adding the x/X bindings.

id:20191113225752.26502-1-jb55@jb55.com is also recommended, it adds a
bind for opening a thread in notmuch-tree mode.

[PATCH 1/7] emacs/tree: return true if a thread was found in next-thread

[William Casarin]

This will allow us to pop back to parent buffers when there are no
more threads to jump to.

[PATCH 3/7] emacs/tree: add notmuch-tree-matching-message

[William Casarin]

This functions removes some duplicate logic between
notmuch-tree-{next,prev}-matching-message

We do this because we will be adding some additional logic similar to
the notmuch-show-next-open-message function, and it will help if this
logic is all in one place.

[PATCH 7/7] emacs/tree: add x/X bindings

[William Casarin]

Add x and X binds to notmuch-tree for functionally that we have in
notmuch-show.

The notmuch-tree-quit binding is somewhat redundant, since it is
handled by notmuch-bury-or-kill-this-buffer which is bound to q.

bah, this should be

  (if (and (not (notmuch-tree-goto-matching-message prev)) pop-at-end)

since short-circuit evaulation prevents the goto-matching-message from
getting called.

I'll push out a v2 later if this gets enough Concept ACKs.

The changes make sense to me in principle, but I don't use
notmuch-tree. It would be good if someone who does could try them and
comment.

I didn't either but I realized it's quite nice for viewing long threaded
discussions. The main  reason I never used it before  was because of the
different keybinds and missing functionality. My goal is to try to bring
as many  things over  as possible  so that  notmuch-show users  can feel
comfortable in notmuch-tree.

x/X was the  big one for me. The  only else perhaps is a  button to quit
both windows at the same time. I  added this functionality in one of the
patches (prefix argument to notmuch-tree-quit) so we just need a keybind
for it now.

If anyone  is interested in  trying this  out I've pushed  these patches
plus the M-RET binding to my github:

    git fetch https://github.com/jb55/notmuch tree-improvements

Cheers,
Will

I have not tested the patch set yet but I think it is very good idea to
add x/X keybindings to make tree view work similarly to show view.
Perhaps I will try the patch set later. Would you mind sending a fixed
version of "PATCH 5/7" (see id:87mucuay8p.fsf@jb55.com)?

Now I have been using the patch set some days and it works as expected.
Usually I open a thread with M-TAB (notmuch-tree-from-search-thread) and
if I then find thread uninteresting I hit "X"
(notmuch-tree-archive-thread-then-exit) and continue browsing the thread
list.

I'm quite experienced with Emacs Lisp (and Common Lisp) but I don't know
Notmuch Emacs code to give educated comments on this patch set's code.
From user's side it works and I support this feature. Thanks!
