[PATCH] emacs: make `notmuch-show-open-or-close-all' toggle visibility

[PATCH] emacs: make `notmuch-show-open-or-close-all' toggle visibility

[Pieter Praet]

* emacs/notmuch-show.el (notmuch-show-open-or-close-all):
  Rename to `notmuch-show-toggle-all-messages', and make it toggle
  visibility of all messages based on the visibility of the current
  message, instead of setting visibility based on whether or not a
  prefix arg was supplied.

Same functionality, less effort (reaching for 'C-u' is a pain)...

The behaviour you've provided is not what I want, from two perspectives:
        - currently it's clear what will happen when I use M-RET or
          C-uM-RET without me having to think about whether the cursor
          is over an open message,
        - often I'll be reading an open message and I want to open all
          of the rest to look at some context. That's a little more
          awkward after this change.

Yes, let's just switch. c-u M-RET to expand and M-RET to collapse (!!!)

(Needless to say I've never expanded but often collapsed ;)

I may be missing something, but wouldn't both issues be solved by simply
pressing M-RET a second time?  I've been using this for a little while
now, and IMO it makes navigating through long and diverging threads a lot
faster, much like zooming in/out on an outline.

How about if C-u M-RET behaved as usual ?

Okay, I used it for a day and I'm happy that the original patch is
good.

Should the function name include "visible" or "visibility" to make it
clear what is toggled?  E.g. `notmuch-show-toggle-visibility-all'.

Also, consider changing "all-messages" to just "all" or "thread".  That
seems to be more consistent with other functions.

Please rename "toggle" to "visible-p".  That would make it more clear
what the variable means, and is consistent with
`notmuch-show-message-visible-p'.

A new `notmuch-show-mapc' function was introduced in a recent commit.
Please use it here instead of a custom loop.

> +  (recenter-top-bottom 1)

There was no `recenter-top-bottom' call before.  Why is it needed now?
It seems like an independent change and, if it is needed, would be
better as a separate patch.  At the very least, it's worth mentioning in
the preamble and perhaps in a comment.

Good point, but we also have `notmuch-show-toggle-message' and
`notmuch-show-toggle-headers', so `notmuch-show-toggle-visibility-all'
would imply that both messages as well as headers are toggled.

Also, `notmuch-show-toggle-visibility-thread' sounds to me like
it would toggle the thread itself instead of the messages of
which it is composed, so my personal expectation would be that
it just blanks the entire buffer. (what's in a name....)

How about renaming the relevant functions like so:
- `notmuch-show-toggle-headers'    -> `notmuch-show-toggle-visibility-headers'
- `notmuch-show-toggle-message'    -> `notmuch-show-toggle-visibility-message'
- `notmuch-show-open-or-close-all' -> `notmuch-show-toggle-visibility-messages'

AFAIK the '-p' suffix is "reserved" for predicate functions, and
using it for a variable could be confusing.  But I'm not aware of
any guidelines on indicating the variable type except when it
stores one or more functions [1,2]...

Perhaps we could call it `visible-bool' ?

Anyways, I've gone with your suggestion: `visible-p' it is...

It ensures that the message being uncollapsed is put properly in view
(instead of starting somewhere in the middle of the buffer) whilst also
making it obvious that/if/when there's previous messages in the thread
(due to its argument being 1 instead of 0).

I thought about using `notmuch-show-message-adjust' instead, but that
obscures the fact that there's previous messages.

As it's quite essential in making the function DTRT, I've opted to
clarify it in a comment as well as the commit message instead of
splitting it out into a separate patch.

So... I've expanded the test suite to cover everything I might be
breaking, renamed the toggle functions to be consistent, and addressed
all your comments in some way or another.  I've also thrown in a bonus
patch which is *not* meant to be applied (WIP, should eventually provide
functionality similar to `notmuch-search-filter{,-by-tag}').

Patches follow.

[PATCH v2 1/7] test: emacs: new tests "notmuch-show: {show, hide} message headers"

[Pieter Praet]

* test/emacs:

  - New subtest "notmuch-show: show message headers":
    Setting `notmuch-message-headers-visible' to t causes all headers
    defined in `notmuch-message-headers' to be shown.

  - New subtest "notmuch-show: hide message headers":
    Setting `notmuch-message-headers-visible' to nil causes all headers
    defined in `notmuch-message-headers' to be hidden.
    ("Subject:" may be an exception;  See the use of `headers-start' in
    `notmuch-show-insert-msg')

  - New subtest "notmuch-show: hide message headers (w/ notmuch-show-toggle-headers)":
    Setting `notmuch-message-headers-visible' to t causes all headers
    defined in `notmuch-message-headers' to be shown, but they can be
    hidden for the current message by running `notmuch-show-toggle-headers'.

+Hello,
+
+First of all, notmuch is a wonderful idea, both the cmdline tool and

+
+Have you considered sending an announcement to the org-mode mailing list?

+
+Various ways of searching/referencing emails from emacs were discussed

+
+ Ah, here's where I planned a nice welcome. So welcome (again), Jan! :-)
+
+ I've been having a lot of fun with notmuch already, (though there have
+ been some days of pain before it was functional enough and my
+ email-reply latency went way up). But regardless---I got through that,
+ and I'm able to work more efficiently with notmuch now than I could with
+ sup before. So I'm happy.
+
+ And I'm delighted when other people find this interesting as well.
+

+
+ Thanks for the idea. I think I may have looked into org-mode years ago,
+ (when I was investigating planner-mode and various emacs "personal wiki"
+ systems for keeping random notes and what-not).
+
+ > Various ways of searching/referencing emails from emacs were discussed

+
+ Yeah. I'll drop them a mail. Having a real emacs wizard on board would
+ be nice. (I'm afraid the elisp I've written so far for this project is
+ fairly grim.)

[PATCH v2 6/7] emacs: make `notmuch-show-toggle-visibility-messages' live up to its new name

[Pieter Praet]

* emacs/notmuch-show.el (notmuch-show-toggle-visibility-messages):
  Toggle visibility of all messages in current thread based on visibility
  of the current message, instead of setting visibility based on whether
  or not a prefix arg was supplied.

  Also move current buffer line to the 2nd window line so the current
  message is put properly into focus, whilst making the presence of
  previous messages in the thread obvious.

Same functionality, less effort (reaching for 'C-u' is a pain)...

[Pieter Praet]

* emacs/notmuch-show.el (notmuch-show-toggle-visibility-messages):
  When provided with a prefix arg, prompt the user for a tag.

Re: [PATCH v2 3/7] emacs: rename `notmuch-show-toggle-headers' to `notmuch-show-toggle-visibility-headers'

This patch, and its predecessors, all look great to me. The following
patches were already marked "stale" (and indeed they don't apply). But
it looks like David Edmonson gave his +1 on the idea, so maybe you
should rebase them.

Side note: how do you write these tests? How do you generate what the
output should look like? Copy/paste from a "real" emacs session? You
have generated an awful lot of tests :)

But a note: many of the first lines in your commit messages ("{show,
hide} message headers") contain tabs. I hate tabs. Is this intentional?
I have noticed it on other patches you've sent (such as
id:"1330122640-18895-6-git-send-email-pieter@praet.org" and
id:"1330122640-18895-7-git-send-email-pieter@praet.org").

I also see tabs, but when I press '<' (remove indent) then
those tabs go away... I guess emacs (or notmuch indentation code)
uses tabs when doing message indenting ?

Hmm, first lines -- IIRC mailman adds those tabs to the subject line -- and
those are converted to spaces in git-am (??)

I guess this is called "line folding" and notmuch should be sure to undo
it, as I guess git-am already does.

I guess I can stop complaining about it ;) Patches 1-3 are probably ready
then. Thanks, Tomi.

Np. Tests pass and the function name change is trivial. 
Removed needs-review on these 3 patches.
