ed03babd05 emacs/tree: fix docstrings for author faces
The docstrings for notmuch-tree-match-author-face and
notmuch-tree-no-match-author-face incorrectly match the docstring of
notmuch-tree-match-date-face.

20b2150406 emacs: don't add space to tag completion candidates.
Apparently this messes up various third party completion
frameworks. This change does mean that users will have to hit space
after completing a tag change in order to enter another change.

As a bonus, remove the call to #'delete, since
completing-read-multiple already promises to remove empty strings.

eafb033d32 emacs: run notmuch-search-hook lazily
In message id:YT3ueuZHKW931NW3@localhost, Fabio Natali isolated a
visual glitch caused by running notmuch-search-hook too early. This
change moves the running of that hook to
notmuch-search-process-filter, which ensures there is some output in
the buffer before running the hook. Since n-s-p-f can be called many
times for a given buffer, add a buffer local flag to make sure it is
only run once per buffer.

20b2ae1218 emacs: drop C-tab binding in hello mode, document <backtab>.
The <backtab> binding has always been there, but the docs were
apparently mistakenly changed to say <backspace> [1]

Revert to <backtab> in the documentation.

The commit also drops the C-<tab> binding, since it seems redundant
and it interferes with tab-bar-mode.

If the car of an element in notmuch-search-result-format is a
function, insert the result of calling the function into the buffer.

This allows a user to generate custom fields in the output of a search
result. For example, with:

(defun -notmuch-result-flags (format-string result)
  (let ((tags-to-letters '(("flagged" . "!")
			   ("unread" . "u")
			   ("mine" . "m")
			   ("sent" . "s")
			   ("replied" . "r")))
	(tags (plist-get result :tags)))

    (format format-string
	    (mapconcat (lambda (t2l)
			 (if (member (car t2l) tags)
			     (cdr t2l)
			   " "))
		       tags-to-letters ""))))

(setq notmuch-search-result-format '((-notmuch-result-flags . "%s ")
				     ("date" . "%12s ")
				     ("count" . "%9s ")
				     ("authors" . "%-30s ")
				     ("subject" . "%s ")
				     ("tags" . "(%s)")))

The first few characters on each line of the search result are used to
show information about some significant tags associated with the
thread.

731697d671 CLI: define and use format version 5
This is a bit of a cheat, since the format does not actually

this to shared libary SONAMEs when the ABI changes in some subtle way.
It does rely on the format-version argument being early enough on the

b649b0c871 emacs: notmuch-tree: mark the initial message at point as read
When moving between message in a tree or show buffer, the message at
point is marked as read.  Likewise when creating such a buffer, then
the message that is initially at point is supposed to be marked as
read as well.

The latter worked for `notmuch-show' but not for `notmuch-tree'.
Press "RET" or "M-RET" in a search buffer to observe these behaviors.

In both cases the marking is supposed to be done by the function
`notmuch-show-command-hook'.  In the case of `notmuch-show' that
function is added directly to `post-command-hook'.

`notmuch-tree' instead adds the function `notmuch-tree-command-hook'
to `post-command-hook' and that calls `notmuch-show-command-hook',
in the respective show buffer, but of course only if that exists.

Because the tree buffer is created asynchronously, the show buffer
doesn't exist yet by the time the `post-command-hook' is run, so
we have to explicitly run `notmuch-tree-command-hook' once the
show buffer exists.

The show buffer is created when `notmuch-tree-goto-and-insert-msg'
calls `notmuch-tree-show-message-in'.  `notmuch-tree-process-filter'
is what finally brings us here.

This is more efficient than notmuch-show-only-matching-messages, since
we do not parse the potentially large thread structure to find a
single message.

This is only a partial fix for notmuch-tree view, because displaying
the thread structure in the tree-mode window still crashes on long
threads. It is however enough to make unthreaded view handle long
threads.

fb4b45062f emacs: remap send-message and send-message-and-exit
All three of C-c C-c, <menu-bar> <Message> <Send Message>,
and <tool-bar> <Send Message> are bound to message-send-and-exit by
message.el, but notmuch-mua.el only had an explicit override for the
keyboard binding. This mostly manifests as confusing Fcc behaviour for
GUI users.

Patching the bindings for specific keys is rather brittle, since it has
to be aware of every relevant binding. This change switches to instead
using a remap binding, which turns any binding for message-send or
message-send-and-exit into a binding for the corresponding notmuch-mua
command.

5cc106b0e3 emacs: use new face for notmuch-jump and related
The minibuffer-prompt face that was used before made it impossible to
differentiate between two distinct UI elements: (i) the prompt's text
which itself cannot be acted upon, (ii) the actionable keys used to
jump to searches/tags.

The use of a named face, notmuch-jump-key, makes it possible for users
or theme developers to apply properties that are specific to each of
those two cases.

In the interest of backward compatibility, the new face inherits from
minibuffer-prompt.

Users may type some text into the buffer on an address line, before
actually invoking address completion.  We now use that text as the
initial input when we begin address completion.

Previously we did knowingly replace the actual initial input with some
completion candidate that happens to match. Which candidate is used is
essentially random, at least when the actual initial input is short.
As a result users very often had to begin completion by deleting the
less than helpful "initial input".

9ca1f945d9 emacs: improve how cl-lib and pcase are required
We need to load `cl-lib' at run-time because we use more from it than
just macros.  Never-the-less many, but not all libraries required it
only at compile-time, which we got away with because at least some
libraries already required it at run-time as well.

We use `cl-lib' and (currently to a lesser extend) `pcase' throughout
the code-base, which means that we should require these features in
most libraries.

In the past we tried to only require these features in just the
libraries that actually need them, without fully succeeding.  We did
not succeed in doing so because that means we would have to check
every time that we use a function from these features whether they
are already being required in the current library.

An alternative would be to add the `require' forms at the top of every
library but that is a bit annoying too.

In order to make sure that these features are loaded when needed but
also to keep the noise down we only require them in "notmuch-lib.el",
which most other libraries require, and in most of the few libraries
that do not do so, namely "notmuch-draft.el", "notmuch-message.el" and
"notmuch-parser.el".  ("coolj.el", "make-deps.el", various generated
libraries, and "notmuch-compat.el" are left touched.)

f47e3333b5 emacs: avoid unnecessary let-bindings
To some extend this is a personal preference, but the preference is
strongly dependent on whether one is used to a language that makes it
necessary to use variables like this.

This makes it perfectly clear that we are first getting and then using
a "foo":

  (use-foo (get-foo))

Sure this has to be read "inside out", but that's something one better
gets used to quickly when dealing with lisp.  I don't understand why
one would want to write this instead:

  (let ((the-foo (get-foo)))
    (use-foo the-foo))

Both `get-foo' and `use-foo' are named in a way that make it very
clear that we are dealing with a "foo".  Storing the value in an
additional variable `the-foo' does not make this any more clear.

On the contrary I makes the reader wonder why the author choose to
use a variable.  Is the value used more than once?  Is the value
being retrieved in one context and then used in another (e.g. when
the current buffer changes)?

Previously they were declared, which keeps the byte-compiler quiet but

made them buffer-local in the current buffer and then set the local

37bb41a792 emacs: notmuch-mua-prompt-for-sender: don't force Ido on users
We shouldn't force `ido-completion-read' on users who do not otherwise
use Ido.  Unfortunately simply turning on `ido-mode' does not change
every `completing-read' into a `ido-completing-read', instead it only
changes file and buffer completion.

I do realize that existing Ido users will initially dislike this
change, but I would like to encourage them to see this as an
opportunity to learn about Fido.

Unlike `ido-mode', build-in `fido-mode' confirms to the standard
completion API, so turning it on causes every `completing-read' to
use the Fido completion mechanism and which is similar to the Ido
mechanism:

> An enhanced `icomplete-mode' that emulates `ido-mode'.  This global
> minor mode makes minibuffer completion behave more like `ido-mode'
> than regular `icomplete-mode'."

93c95802a4 emacs: inline notmuch-sexp-eof into only caller
This function had a few issues.
- Neither its name nor the old comment before it is called made it
  clear what it does.
- It took one argument but didn't do anything with it.
- It's doc-string made a few claims, which are untrue and generally
  focused on details instead of that its purpose is.

0067a43ea2 emacs: deal with unused lexical arguments and variables
The previous commit switched to lexical-binding but without dealing
with the new warnings about unused lexical arguments and variables.

This commit deals with most of them, in most cases by either removing
leftover bindings that are actually unnecessary, or by marking certain
arguments as "known to be unused" by prefixing their names with "_".

In the case of the functions named `notmuch-show-insert-...' the
amount of silencing that is required is a bit extreme and we might
want to investigate if there is a better way.

In the case of `notmuch-mua-mail', ignoring CONTINUE means that we do
not fully follow the intended behavior described in `compose-mail's
doc-string.

fc4cda07a9 emacs: use lexical-bindings in all libraries
Doing so causes many new compile warnings.  Some of these warnings
concern genuine changes in behavior that have to be addressed right
away.

Many other warnings are due to unused variables.  Nothing has changed
here, except that the byte-compiler can now detect these pre-existing
and harmless issues.  We delay addressing these issues so that we can
focus on the important ones here.

A third group of warnings concern arguments that are not actually used
inside the function but which cannot be removed because the functions
signature is dictated by some outside convention.  Silencing these
warning is also delayed until subsequent commits.

2ca941163d emacs: make headings outline-minor-mode compatible
`outline-minor-mode' treats comments that begin with three or more
semicolons as headings.  That makes it very convenient to navigate
code and to show/hide parts of a file.

Elips libraries typically have four top-level sections, e.g.:

;;; notmuch.el --- run notmuch within emacs...
;;; Commentary:...
;;; Code:...
;;; notmuch.el ends here

In this package many libraries lack a "Commentary:" section, which is
not optimal but okay for most libraries, except major entry points.

Depending on how one chooses to look at it, the "... ends here" line
is not really a heading that begins a section, because it should never
have a "section" body (after all it marks eof).

If the file is rather short, then I left "Code:" as the only section
that contains code.  Otherwise I split the file into multiple sibling
sections.  The "Code:" section continues to contain `require' and
`declare-function' forms and other such "front matter".

If and only if I have split the code into multiple sections anyway,
then I also added an additional section named just "_" before the
`provide' form and shortly before the "...end here" line.  This
section could also be called "Back matter", but I feel it would be
distracting to be that explicit about it.  (The IMO unnecessary but
unfortunately still obligatory "... ends here" line is already
distracting enough as far as I am concerned.)

Before this commit some libraries already uses section headings, some
of them consistently.  When a library already had some headings, then
this commit often sticks to that style, even at the cost inconsistent
styling across all libraries.

A very limited number of variable and function definitions have to be
moved around because they would otherwise end up in sections they do
not belong into.

Sections, including but not limited to their heading, can and should
be further improved in the future.

adc123e4fd emacs: avoid killing process buffer when process is still alive

904ffbc925 emacs: avoid passing around some redundant information
When running "notmuch" we use its full path but when displaying the
command to the user we show just its name for readability reasons.
Avoid passing around both representations because it is very easy
to get the name from the path.

Notmuch itself uses the involved functions just for "notmuch" but
there might be extensions that use them for other executable so we
forgo other potential simplifications.

d7b83385af emacs: sanitize dedicated widget action/notify functions
These functions are used as action/notify functions.  That dictates
the appropriate function signatures but even though these functions
are not used for anything else they use incompatible signatures,
forcing the callers to use lambda expressions to deal with these
incompatibilities.

Fix that by adjusting the function signatures to the needs of the
only intended callers.

Two of these functions were defined as commands but because the
interactive form did not return the mandatory arguments, we know
that nobody (successfully) used these as commands.

In one case we move the location of a y-or-n-p prompt.

0251cab3ab Revert "emacs: notmuch-search: avoid wiping out buffer-local variables"
This reverts commit f9fbd1ee3b.

Emacs provides a mechanism for avoiding wiping out buffer-local
variables: marking them as "permanent local", which essentially
means "don't wip out the local value when enabling major-mode".

  (put 'the-variable 'permanent-local t)

See (info "(elisp)Creating Buffer-Local").

Whether refreshing the buffer contents should involve re-enable the
mode is a different question, which should not be decided based on
the fact that we want keep the value of some random variable, not
least because some other (e.g. cache) variables are likely expected
to be wiped.

adfded9ed0 emacs: avoid binding unnamed commands in keymaps
One should never bind unnamed commands in keymaps because doing that
makes it needlessly hard for users to change these bindings.

Replace such anonymous bindings with named commands that are generated
using macros and some boilerplate. Using macros is better than using a
simple loop because that makes it possible for `find-function' to find
the definitions. Eat your boilerplate--it forms character.

Admittedly this approach is quite ugly and it might be better to teach
the original commands to support different buffers directly instead of
requiring wrapper commands to do just that.

Never-the-less as a short-term solution this is better than what we
had before.

4f57e01843 emacs: inline notmuch-documentation-first-line
Inline a simplified version of `notmuch-documentation-first-line'
into its only caller.  The new code snippet differs from the
removed function in that it returns nil instead of the empty string
for symbols that have no function documentation.  That value is
ultimately used as an argument to `concat', which treats nil like
the empty string.  So we can do the logical thing without changing
the behavior.
