The new notmuch-search-hide-excluded option allows users to configure whether
to show or hide excluded messages (as determined by search.exclude_tags
in the local notmuch config file). It defaults to true for now to maintain
backwards-compatibility with how notmuch-{search,tree} already worked.
New commands notmuch-search-toggle-hide-excluded and
notmuch-tree-toggle-exclude have also been added. They toggle the value
of notmuch-search-hide-excluded for the search in the current search or
tree buffer. It's bound to "i" in the respective keymaps for these
modes.
Lastly I've amended some calls to notmuch-tree and notmuch-unthreaded
which didn't pass through the buffer local value of
notmuch-search-oldest-first (and now notmuch-search-exclude).
Examples of where I've done this include:
+ notmuch-jump-search
+ notmuch-tree-from-search-current-query
+ notmuch-unthreaded-from-search-current-query
+ notmuch-tree-from-search-thread
A new test file for Emacs has been added which covers the usage of the
new `notmuch-search-hide-excluded' option and interactively hiding or
showing mail with excluded tags. These test cover the basic usage of
the `notmuch-search-toggle-hide-excluded' command in notmuch-search,
notmuch-tree and notmuch-unthreaded searches. These tests also cover
the persistence of the current value of the hide-excluded mail option
as a user switches from between these different search commands.

For some kinds of MIME parts (at least images), our trickery with
overlays will not work, so save the more drastic function created by
Gnus that actually deletes the part from the buffer. In an ideal world
we would return this function as (part of) a value, but here the call
stack is too complicated for anything that simple, so we stash it in
the part plist and rely on that being preserved (unlike the mm handle,
which is transient).
This new command allows the user to interactively choose a different
duplicate (file) to display for a given message in
notmuch-show-mode. Since both tree and unthreaded view use
notmuch-show-mode, this provides the same facility there.
The only functionality actually used by notmuch is the base function
notmuch-query-get-threads; the other functions in this file have
nothing to do with that (single) use. Move that function into
notmuch-lib.el and rename to reflect use. Deprecate the other
functions in notmuch-query.el.
This variable is important for people who want to change the default
behaviour when displaying multipart/alternative messages. Previously
it was undocumented. Add a defcustom to help users and copy some
documentation from the wiki. The usual machinery of re-using
docstrings is a bit tricky to use here because it mangles the example
lisp code, and the link to the info node should not be in e.g. the
html page.
Add a simple test to make sure the switch from defvar to defcustom did
not break something obvious.
The intended use case of this new function is to make reply behaviour
track that of show with respect to attachments.
Also fix the glob (which worked by fluke) into the documented regexp.
As with notmuch--process-lines, initial purpose is to provide a safe
binding for default-directory. This is enough to make notmuch-hello
robust against non-existent or corrupt values default-directory, but
probably not other views.
Initially just set the working directory, to avoid (the implicit)
call-process crashing when the default-directory points to a
non-existent location.
Use of a macro here is over-engineering for this change, but the same
change needs to be applied to several other process creation
primitives.
The output of "notmuch show --format=sexp --format-version=4"
may contain `:content-type' entries with `nil' as the value,
when it fails to detect the correct value. Account for that
in a few places where we would otherwise risk a type error.
Note that `string=' does not choke on `nil' because it uses
the `symbol-name' when encountering a symbol.
Like `cl-lib' and `pcase', which are already available in all
libraries, `subr-x' also provided many useful functions that
we would like to use.
Making `subr-x' available in every library from the get-go means
that we can use the functions it defines without having to double
check every single time, whether the feature is already available
in the current library.
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.)
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)?
Define these variables as automatically buffer-local, meaning that
they always become buffer-local when set unless explicitly told
otherwise using `setq-default' or when using the Custom interface.
Previously they were declared, which keeps the byte-compiler quiet but
is not actually the same as being defined. `notmuch-search-mode' then
made them buffer-local in the current buffer and then set the local
values. This works but is not kosher.
The definitions of the three non-option variables have to be moved up
a bit to enable the change in the next commit, which see.
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.
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.
`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.
In practice this probably does not make a difference or we would
have heard about it many times, but better be safe than sorry.
Process sentinels are called not only when the process has finished
but also on other state changes.
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.
The buffer of the error process is accessible using `process-buffer'.
We still have to store the error-buffer in the non-error process
because for that process `process-buffer' obviously returns its own
buffer.
We no longer support Emacs releases before version 25.1.
Also adjust the sentinels which only had to deal with
an error file when using an older Emacs release was used.
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.
We could just have switched to using `cl-remove-if-not' instead,
but the two uses of the *remove-if-not function are pretty strange
to begin with so we refactor to not use any such function at all.
Previously it was defined in "notmuch-hello.el" and its name contained
"hello" solely because it replaced an anonymous function that was
mistakenly only bound in `notmuch-hello-mode-map'. But it makes more
sense to bind it in all notmuch modes and even if we did not change
that aspect it still would make no sense to have "hello" in its name.
Notmuch requires at least version 25 of Emacs now.
Adjust comments that previously referenced version 24 specifically,
even though they also apply to later releases. Remove documentation
and code that no longer applies.
- `mm-shr' no longer references `gnus-inhibit-images'.
This function is being autoloaded using an autoload cookie, so it
shouldn't additionally be autoloaded using an `autoload' form.
When building libraries we don't actually load the autoloads file and
dropping the `autoload' form results in an error, which reveals a so
far unspecified dependency: `notmuch-tree' needs `notmuch-jump'.
Before this commit compiling (or even just loading) `notmuch-tree'
resulted in `notmuch-jump' being loaded because the former requires
`notmuch-lib', which autoloaded `notmuch-jump-search'.
The bug was that this dependency was not explicitly specified, which
we fix by adding the respective `require' form.
It's a bit weird to avoid having to write the "(setq ... )" more than
once, just because we can. In a language that uses '=' for the same
purpose we also happily use that once per assignment.
While there are no benefit to using just one 'setq' there are some
drawbacks. It is not always clear on first what is a key and what a
value and as a result it is easy to make a mistake. Also it becomes
harder to comment out just one assignment.
Most people who write lots of lisp tend to only sparsely use empty
"separator" lines within forms. In lisp they feel unnecessary and
since most files stick to this convention we get a bit confused
when there are extra empty lines. It feels like the s-expressions
are falling into pieces.
All of this is especially true between a function's doc-string and
body because the doc-string is colored differently, which visually
already separates it quite sufficiently from the code that follows.
