This is v2 of the patch set. Version 1 is at
id:1390087855-26194-1-git-send-email-markwalters1009@gmail.com.

The changes in this version are: use regexp tag-format matching (a
slightly tweaked version of Austin's patch
id:1392226351-31440-1-git-send-email-amdragon@mit.edu), make the
tag-deleted/added formats apply on top of the normal tag-formatting,
and fixup the way the :orig-tags field is added in notmuch-search.

I think this version fixes all outstanding review comments.

Best wishes

Mark

From: Austin Clements <amdragon@MIT.EDU>

This patch switches notmuch-tag-formats to use regexps with caching
for performance.

We have to clear the cache somehow on changes to notmuch-tag-formats.
This version takes the simplest approach: search/show/tree all clear
the cache whenever they start loading.

We cannot use assoc-default since there's no way to distinguish a
missing key from a present key with a null cdr: thus, we use assoc*
from cl instead.

Performance-wise, the caching of regexp lookup makes this at least as
fast as the previous code using assoc (see
id:1392226351-31440-1-git-send-email-amdragon@mit.edu for timing
details).

We will re-use the customize option for format-tags for formattting
deleted tags to added tags in the next patch so split it into a
widget. There should be no functional change.

Add customize options for deleted/added tag formats.  These are not
used yet but will be later in the series.

This allows (and requires) the original-tags to be passed along with
the current-tags to be passed to notmuch-tag-format-tags. This allows
the tag formatting to show added and deleted tags.By default a removed
tag is displayed with strike-through in red (if strike-through is not
available, eg on a terminal, inverse video is used instead) and an
added tag is displayed underlined in green.

If the caller does not wish to use the new feature it can pass
current-tags for both arguments and, at this point, we do exactly that
in the three callers of this function.

Note, we cannot tidily allow original-tags to be optional because we would
need to distinguish nil meaning "we are not specifying original-tags"
from nil meaning there were no original-tags (an empty list).

We use this in subsequent patches to make it clear when a message was
unread when you first loaded a show buffer (previously the unread tag
could be removed before a user realised that it had been unread).

The code adds into the existing tag formatting code. The user can
specify exactly how a tag should be displayed normally, when deleted,
or when added. For convenience an entry for the empty string in the
notmuch-tag-formats (and the corresponding notmuch-tag-deleted-formats
notmuch-tag-added-formats) is applied to all tags which do not have an
explicit match.

This means that a user can tell notmuch not to show deleted tags at
all by setting notmuch-tag-deleted-formats to
'(("" nil))
or not to show any deleted tags except "unread" by setting it to
'(("" nil)
  ("unread" (propertize tag 'face '(strike-through "red"))))

All the variables are customizable; however, more complicated cases
like changing the face depending on the type of display will require
custom lisp.

Currently this overrides notmuch-tag-deleted-formats for the tests
setting it to '(("" nil)) so that they get removed from the display
and, thus, all tests still pass.

This uses the previous patch to show the tag changes that have occured
in the show buffer since it was last loaded/refreshed.

This uses the recent functionality to show the tag changes in the
search buffer. Currently this is only used to show changes the search
buffer makes itself: i.e., it does not make display any changes
reflecting tagging done by other notmuch-buffers.

This is a rewrite of this single patch. When trying to rebase my
unread stuff on top of this series I realised that the previous
version split the notmuch-search-show-result in a a strange place. In
particular the code for "is this the target thread" so should only be
called when building the buffer not when redisplaying a thread. Of
course it works either way but I think this is cleaner.

Best wishes

Mark

Just for the record, I've been using this version for a while (and the
previous versions before that), and I still think it's one of the best
emacs UI improvements we've had lately. Would be great to have this
merged.

How about this for a commit message?

- 8< -

This modifies `notmuch-tag-format-tag' to treat the keys of
`notmuch-tag-formats' as (anchored) regexps, rather than literal
strings.  This is clearly more flexible, as it allows for prefix
matching, defining a fallback format, etc.  This may cause compatibility
problems if people have customized `notmuch-tag-formats' to match tags
that contain regexp specials, but this seems unlikely.

Regular expression matching has quite a performance hit over string
lookup, so this also introduces a simple cache from exact tags to
formatted strings.  The number of unique tags is likely to be quite
small, so this cache should have a high hit rate.  In addition to
eliminating the regexp lookup in the common case, this cache stores
fully formatted tags, eliminating the repeated evaluation of potentially
expensive, user-specified formatting code.  This makes regexp lookup at
least as fast as assoc for unformatted tags (e.g., inbox) and *faster*
than the current code for formatted tags (e.g., unread):

                    inbox (usec)   unread (usec)
    assoc:              0.4            2.8
    regexp:             3.2            7.2
    regexp+caching:     0.4            0.4

(Though even at 7.2 usec, tag formatting is not our top bottleneck.)

This cache must be explicitly cleared to keep it coherent, so this adds
the appropriate clearing calls.

This is no longer true, so this comment can be removed and the following
two defs can be moved to a more natural location further down in the

Likewise, this sentence is out of date.  I would just omit it and add

This would be a great place to mention that modes need to call
`notmuch-tag-clear-cache' if they intent to use formatted tags.

  "Format TAG according to `notmuch-tag-formats'.

Callers must ensure that the tag format cache has been recently cleared
via `notmuch-tag-clear-cache' before using this function.  For example,
it would be appropriate to clear the cache just prior to filling a
buffer that uses formatted tags."

It occurs to me that `propertize' is problematic here, since it replaces
the face property of the tag wholesale.  If we really want this to apply
in addition to a face added by notmuch-tag-formats, I don't think
there's any way to massage things so that `propertize' works (short of
horrible hackery).  `notmuch-combine-face-text-property-string' does
exactly what we need here, but maybe needs a shorter name?
`notmuch-apply-face'?  Or maybe there's some solution I'm not thinking
of?

I like this better than v2 as well.

* [PATCH] emacs: Combine notmuch-combine-face-text-property{,-string}

This combines our two face combining functions into one, easy to use
function with a much shorter name: `notmuch-apply-face'.  This
function takes the full set of arguments that
`notmuch-combine-face-text-property' took, but takes them in a more
convenient order and provides smarter defaults that make the function
easy to use on both strings and buffers.
---

Here's the combined, cleaned up face combiner interface I mentioned on
IRC.  I think the new `notmuch-apply-face' function introduced here
would be ideal for use in notmuch-tag-formats to fix the problem with
propertize overriding the entire face.
