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.
Previously tree did not use tag-format-tags: since tree wants to
distinguish matching messages from non-matching messages it is not a
perfect fit.
However, in preparation for allowing tag-changes to be shown (i.e.,
added or deleted tags to be indicated) it is convenient to make all
places displaying tags call the same routines.
We modify notmuch-tag-format-tags slightly so that it can take and
argument for the default characteristics of the face before the
special tag features are applied.
This also means that things like the star symbol for flagged messages
all work in tree.
(Unfortunately, it's difficult to first demonstrate this problem with
a known-broken test because modern Linux kernels have argument length
limits in the megabytes, which makes Emacs really slow!)
Previously, when a user fully completed a tag operation, they had to
press space to begin entering another tag operation. This is
different from, say, shell file name completion, which typically
inserts a space after an unambiguous completion under the assumption
that the user will want to enter more input.
This patch tweaks `notmuch-read-tag-changes' to act more like shell
file name completion: after an unambiguous tag completion, it now
inserts a space, ready and waiting for another tagging operation from
the user. This is backwards-compatible with old habits, since there's
no harm in putting an extra space.
We no longer use this, since we've lifted all interactive behavior to
the appropriate interactive entry points. Because of this,
`notmuch-tag' also no longer needs to return the tag changes list,
since the caller always passes it in.
This modifies the interface of `notmuch-read-tag-changes' to take an
optional prompt string as well as a list of existing tags instead of a
query. This list of tags is used to populate the tag removal
completions and lets the caller compute these in a more
efficient/consistent manner than performing a potentially large or
complex query. This patch also updates the sole current caller of
`notmuch-read-tag-changes'.
Change foreground color to `blue' like lines representing threads
with flagged messages in notmuch-search. Before tag `flagged' was
shown in notmuch-show buffers as image star on graphical frames while
there was no visible distinction to other flags on terminal frames.
When compiling notmuch-tag.el there is a compile warning:
notmuch-tag.el:27:1:Warning: cl package required at runtime
Since we have decided to allow runtime use of cl we suppress this
warning by adding a tail comment to the file.
This patch extracts the rendering of tags in notmuch-show to
the notmuch-tag file.
This file introduces a `notmuch-tag-formats' variable that associates
each tag to a particular format. This variable can be customized
thanks to the work of Austin Clements. For example,
'(("unread" (propertize tag 'face '(:foreground "red")))
("flagged" (notmuch-tag-format-image tag "star.svg")))
associates a red foreground to the "unread" tag and a star picture to
the "flagged" tag.

notmuch-tag is extended to accept various formats of the tag changes.
In particular, user prompting for tag changes is now incorporated
here, so it is common for modes.
The tag binary and the notmuch-{before,after}-tag-hooks are only
called if tag changes is non-nil.
In all cases tag-changes is returned as a list.
Tagging functions are used in notmuch.el, notmuch-show.el, and
notmuch-message.el. There are enough common functions for tagging
that it makes sense to put them all in their own library.
No code is modified, just moved around.
