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.
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 fixes a regression introduced in [1: 7e20d264]. If the argument
RETURN-ACTION was non-nil then we should pass along the value of that
argument. Instead we passed along the constant symbol `return-action'.

emacs: Fix mail composition under Emacs 23
Key bindings should not be defined at the top-level but inside
a `defvar' form. Doing it at the top-level makes it harder to
reliably customize key bindings.
Currently `message-send-hook` functions are being called twice: In
notmuch send common when `notmuch-mua-send-hook` functions are
run (which by default includes `notmuch-mua-message-send-hook`) and in
`message-send` itself.
Because `message-send-hook` functions are run in `message-send` itself,
we don't need also need to run them before we delegate to `message-send`
Calling `notmuch-mua-message-send-hook` resulted in functions in
`message-send-hook` to be called twice. This causes bugs in
non-idempotent hook functions.
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.
Fixed emacs docstrings to be consistent. No functional change.
- removed some (accidental) indentation
- removed some trailing newlines
- added trailing periods where missing (some exclusions)
Starting with Emacs 27 the old `cl' implementation is finally
considered obsolete. Previously its use was strongly discouraged
at run-time but one was still allowed to use it at compile-time.
For the most part the transition is very simple and boils down to
adding the "cl-" prefix to some symbols. A few replacements do not
follow that simple pattern; e.g. `first' is replaced with `car',
even though the alias `cl-first' exists, because the latter is not
idiomatic emacs-lisp.
In a few cases we start using `pcase-let' or `pcase-lambda' instead
of renaming e.g. `first' to `car'. That way we can remind the reader
of the meaning of the various parts of the data that is being
deconstructed.
An obsolete `lexical-let' and a `lexical-let*' are replaced with their
regular variants `let' and `let*' even though we do not at the same
time enable `lexical-binding' for that file. That is the right thing
to do because it does not actually make a difference in those cases
whether lexical bindings are used or not, and because this should be
enabled in a separate commit.
We need to explicitly depend on the `cl-lib' package because Emacs
24.1 and 24.2 lack that library. When using these releases we end
up using the backport from GNU Elpa.
We need to explicitly require the `pcase' library because
`pcase-dolist' was not autoloaded until Emacs 25.1.
This commit changes the behaviour of notmuch-mua-attachment-check
so that it stops searching for notmuch-mua-attachment-regexp when a
new mime-part is reached. This avoids false warnings when matching
words occur inside forwarded messages.
Instead of relying on the "In-Reply-To" header, use a buffer-local variable,
notmuch-message-queued-tag-changes, to add and remove tags to affected
messages when the message-send-hook is triggered.
Include the message-id of forwarded messages in the new message.
This ensures that the new (forwarding) message is linked to the
same thread as the message being forwarded.
Query the user if the message text indicates that an attachment is
expected but no MML referencing an attachment is found.
This is not enabled by default - see the documentation for
`notmuch-mua-attachment-check'.
`mm-inline-text-html-with-images' was removed from mm-decode.el in
2016 and replaced with `mm-html-inhibit-images'.
`gnus-select-frame-set-input-focus' was removed from gnus-util.el in
2016 and existed only for XEmacs compatibility.
This brings the --decrypt argument to "notmuch reply" into line with
the other --decrypt arguments (in "show", "new", "insert", and
"reindex"). This patch is really just about bringing consistency to
the user interface.
We also use the recommended form in the emacs MUA when replying, and
update test T350 to match.
Commit a7964c86d1 ("emacs: Sanitize authors and subjects in search
and show") added sanitization of header information for display. Do
the same for reply subjects.
This fixes the long-standing annoying artefact of certain versions of
mailman using tab as folding whitespace, leading to tabs in reply
subjects.
This provides initial support for postponing in the emacs frontend;
resuming will follow in a later commit. On saving/postponing it uses
notmuch insert to put the message in the notmuch database
Current bindings are C-x C-s to save a draft, C-c C-p to postpone a
draft (save and exit compose buffer).
Previous drafts get tagged deleted on subsequent saves, or on the
message being sent.
Each draft gets its own message-id, and we use the namespace
draft-.... for draft message ids (so, at least for most people, drafts
are easily distinguisable).
If an encrypted multipart message is received which contains html and
notmuch-multipart/alternative-discouraged is set to discourage "text/plain",
any encrypted parts are not decrypted during generation of the reply
text. This fixes that problem by making sure notmuch-mua-reply does
that.
Emacs message-send seems to ignore a secure mml tag anywhere except at
the start of the body, and it must be followed by a newline. Since
this is almost certainly not desired we check for it, and require user
confirmation before sending.
As the setup before message-send or message-send-and-exit is getting
more complicated it is convenient to unify the two correspoinding
notmuch functions.
This commit adds a common message-send function for message-send and
message-send-and-exit. At the moment the overlap is small, but the
message-send function will get more complex.
This stops the (usually incorrect) sigstatus and encstatus buttons
appearing when replying in emacs, and updates the test suite to match.
Overriding the status button functions is a little unusual but much
less intrusive than passing an argument all the way down the call
chain. It also makes it clear exactly what it does.
We also hide the application/pgp-encrypted part as it can only contain
"Version: 1". We do this in notmuch show, which means it also happens
when replying.
We will need our own local copy of message-do-fcc so this commit just
copies the code straight from message.el so that it is easier to see
our local changes coming in the next commit.
This commit lets the user customize the address completion. It makes
two changes.
The first change controls whether to build the address completion list
based on messages you have sent or you have received (the latter is
much faster).
The second change add a possible filter query to limit the messages
used -- for example, setting this to date:1y.. would limit the
address completions to addresses used in the last year. This speeds up
the address harvest and may also make the search less cluttered as old
addresses may well no longer be valid.
The User-Agent: header can be fun and interesting, but it also leaks
quite a bit of information about the user and their software stack.
This represents a potential security risk (attackers can target the
particular stack) and also an anonymity risk (a user trying to
preserve their anonymity by sending mail from a non-associated account
might reveal quite a lot of information if their choice of mail user
agent is exposed).
This change also avoids hiding the User-Agent header by default, so
that people who decide they want to send it will at least see it (and
can edit it if they want to) before sending.
It makes sense to have safer defaults.
Many of the external links found in the notmuch source can be resolved
using https instead of http. This changeset addresses as many as i
could find, without touching the e-mail corpus or expected outputs
found in tests.
When composing messages (including replies, etc.), indicate to
`message-mode' definitively that the message is email (as opposed to
Usenet news) rather than having it attempt to determine this for itself.
This causes `message-mode' to observe such variables as
`message-default-mail-headers', which previously happened haphazardly.
