On some platforms (e.g. macOS), it is necessary to add a real sentinel
process for the error buffer used by `notmuch-start-notmuch' rather
than a no-op sentinel.
We also expand tab completion for it, update the emacs bindings, and
update T350, T357, and T450 to match.
Make use of the bool-to-keyword backward-compatibility feature.
make-process is a new function introduced in Emacs 25, which provides
greater control over process creation. Crucially, it allows
separately redirecting stderr directly to a buffer, which allows us to
avoid needing to use the shell to redirect to a temporary file in
order to correctly distinguish stdout and stderr.
* notmuch-lib.el: Use make-process when it is available; fall back to
the previous method when not.
Load subprocess error output to a string in the callers, and propagate
the error messages as a string parameter instead of a path to file
names.
Required to be able to avoid using temporary files for subprocess
error output.
* notmuch-lib.el: Update notmuch-check-async-exit-status,
notmuch-check-exit-status: accept an err parameter instead of
err-file; shift the responsibility of loading error messages from
files up the call stack.
We now have several customizable options for address completion. There
is a customize group notmuch-address but it only contains one of these
options. Add all the others, and make it part of the notmuch customize
group.
Some of the recent changes to the emacs code have used functions
introduced in emacs 24. The functions used are read-char-choice and
setq-local. This changeset adds a file notmuch-compat.el which
contains compatibility functions so that it should work on emacs
23.
Note, since these functions are taken almost unchanged from the emacs
source they are copyright the Free Software Foundation, and the header
in the file reflects that.
We can't use c-u = as some of the notmuch-show refresh function
already uses that. This is a global keybinding for a relatively
infrequent function but M-= seems unlikely to cause conflicts.
notmuch-refresh-all-buffers calls each buffer's major mode specific
refresh function using the generic notmuch-refresh-this-buffer function.
Since the earlier changesets have stopped the refresh functions from
forcing the buffers to be redisplayed this can refresh buffers that
are not currently displayed without disturbing the user. This is very
useful for silent async background updating the emacs display when new
mail is fetched.

This function prints diagnostic information in the event of an
error. However, one of the callers has an optional :stdin-string
keyword argument. This causes the error printing routine to error
itself.
Rather than reach notmuch-check-exit-status about the possible keyword
arguments (currently only one but could be more in the future) this
commit just tells notmuch-check-exit-status how to print non-string arguments.
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.
`notmuch--get-bodypart-raw' previously assumed that all non-binary MIME
parts could be successfully read by assuming that they were UTF-8
encoded. This was demonstrated to be wrong, specifically when a part was
marked as ISO8859-1 and included accented characters (which were
incorrectly rendered as a result).
Rather than assuming UTF-8, attempt to use the part's declared charset
when reading it, falling back to US-ASCII if the declared charset is
unknown, unsupported or invalid.
Currently the preference for which sub-part of a multipart/alternative
part is shown is global. Allow to the user to override the settings on a
per-message basis by providing the ability to call a function that has
access to the message to return the discouraged type list.
The original approach is retained as the default.
`notmuch-get-bodypart-text' assumed that it is always possible to
acquire text/* parts via the sexp output format. This is not true if the
part in question has a content type of application/octet-stream but is
being interpreted as text/* based on the extension of the part filename.
Rework `notmuch-get-bodypart-text' to use the raw output format to
address this and make the implementation common with that of
`notmuch-get-bodypart-binary'.
Previously poll called from emacs would fail silently. This makes it
return a useful error message.
In the non-deprecated case of notmuch new and appropriate hooks, it
uses notmuch-call-notmuch-process which gives an error and
additionally puts the stdout/stderr etc in the *Notmuch errors*
buffer.
In the deprecated case of a custom poll script it only returns an
error message.
Commit based on a bug report, and a potential fix, by Ketil Malde.
Currently, notmuch has an address completion mechanism that requires
external command to provide completion candidates. This commit adds a
completion mechanism inspired by https://github.com/tjim/nevermore,
which is implemented in Emacs lisp only.
The preexisting address completion mechanism, activated by pressing
TAB on To/Cc lines, is extended to use the new mechanism when
notmuch-address-command to 'internal, which is the new default.
The core of the new mechanism is the function notmuch-address-harvest,
which collects the completion candidates from the notmuch database and
stores them in notmuch-address-completions variable. The address
harvesting can run either synchronously (same as with the previous
mechanism) or asynchronously. When the user presses TAB for the first
time, synchronous harvesting limited to user entered text is performed.
If the entered text is reasonably long, this operation is relatively
fast. Then, asynchronous harvesting over the full database is triggered.
This operation may take long time (minutes on rotating disk). After it
finishes, no harvesting is normally performed again and subsequent
completion requests use the harvested data cached in memory. Completion
cache is updated after 24 hours.
Note that this commit restores (different) completion functionality for
users when the user used external command named "notmuch-addresses",
i.e. the old default. The result will be that the user will use
the new mechanism instead of this command. I believe that many users may
not even recognize this because the new mechanism works the same as
http://commonmeasure.org/~jkr/git/notmuch_addresses.git and perhaps also
as other commands suggested at
http://notmuchmail.org/emacstips/#address_completion.
[This feature was significantly improved by David Bremner and Mark Walters]
Now that we have `notmuch-emacs-version' defined in notmuch emacs MUA
use that as a part of User-Agent: header to provide more accurate
version information when sending emails.
In case some incomplete installation of notmuch emacs MUA is used and
`notmuch-emacs-version' is defined as "unknown" then fall back to ask
version info from cli (as it used to be before this commit).
Requiring notmuch-version[.elc] and if that is missing setting
"fallback" notmuch-emacs-version (to "unknown") was moved from
notmuch.el to notmuch-lib.el as notmuch-mua.el (which provides
User-Agent: information) require's the latter.
Unibyte strings are meant for representing binary data. In practice,
using unibyte versus multibyte strings affects *almost* nothing. It
does happen to matter if we use the binary data in an image descriptor
(which is, helpfully, not documented anywhere and getting it wrong
results in opaque errors like "Not a PNG image: <giant binary spew
that is, in fact, a PNG image>").
`notmuch-get-bodypart-content' could do two very different things,
depending on conditions: for text/* parts other than text/html, it
would return the part content as a multibyte Lisp string *after*
charset conversion, while for other parts (including text/html), it
would return binary part content without charset conversion.
This commit completes the split of `notmuch-get-bodypart-content' into
two different and explicit APIs: `notmuch-get-bodypart-binary' and
`notmuch-get-bodypart-text'. It updates all callers to use one or the
other depending on what's appropriate.
The new function, `notmuch-get-bodypart-binary', replaces
`notmuch-get-bodypart-internal'. Whereas the old function was really
meant for internal use in `notmuch-get-bodypart-content', it was used
in a few other places. Since the difference between
`notmuch-get-bodypart-content' and `notmuch-get-bodypart-internal' was
unclear, these other uses were always confusing and potentially
inconsistent. The new call clearly requests the part as undecoded
binary.
This is step 1 of 2 in separating `notmuch-get-bodypart-content' into
two APIs for retrieving either undecoded binary or decoded text.
This introduces notmuch-jump, which is like a user-friendly,
user-configurable global prefix map for saved searches. This provides
a non-modal and much faster way to access saved searches than
notmuch-hello.
A user configures shortcut keys in notmuch-saved-searches, which are
immediately accessible from anywhere in Notmuch under the "j" key (for
"jump"). When the user hits "j", the minibuffer immediately shows a
helpful table of bindings reminiscent of a completions buffer.
This code is a combination of work from myself (originally,
"notmuch-go"), David Edmondson, and modifications from Mark Walters.
notmuch-poll-script has long since been deprecated in favor of
post-new hooks, but this wasn't obvious from the documentation.
Update the documentation to make this clear. Since
notmuch-poll-script could, to some extend, be used to control the path
of the notmuch binary and that use is now clearly discouraged, promote
notmuch-command to a real defcustom instead of just a variable.
The recent changes for saved searches introduced a bug when notmuch
was loaded after the saved search was defined. This was caused by a
utility function not being defined when the defcustom was loaded.
Fix this by moving some code around: the defcustom is moved into
notmuch-hello (which is a more natural place anyway), and the utility
functions are moved before the defcustom in notmuch-hello. We are
rather constrained as the defcustom for saved searches is the first
variable in the notmuch-hello customize window; to avoid moving this
customize the defcustom needs to be the first defcustom in
notmuch-hello, and the utility functions come before that.
This patch also renames one of the utility functions from
notmuch--saved-searches-to-plist to
notmuch-hello--saved-searches-to-plist (as it is purely local to
notmuch-hello) and corrects a couple of typo/spelling mistakes pointed
out by Tomi.
This adds a sort-order option to saved-searches, stores it in the
saved-search buttons (widgets), and uses the stored value when the
button is pressed.
Storing the sort-order in the widget was suggested by Jani in
id:4c3876274126985683e888641b29cf18142a5eb8.1391771337.git.jani@nikula.org.
Make the defcustom for notmuch-saved-searches use the new plist
format. It should still work with oldstyle saved-searches but will
write the newstyle form.
Previously, the term escaper used a blacklist of characters that
needed escaping. This blacklist turned out to be somewhat incomplete;
for example, it did not contain non-whitespace ASCII control
characters or Unicode "fancy quotes", both of which do require the
term to be escaped.
Switch to a whitelist of characters that are definitely safe to leave
unquoted. This fixes the broken test introduced by the previous
patch.
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.
When "notmuch config" is called with the name of an empty or
unconfigured setting, it prints nothing (not even a new line).
Previously, `notmuch-config-get' assumed it would always print a
newline. As a result, when `notmuch-config-get' was called with the
name of an empty of unconfigured setting, it would attempt to
(substring "" 0 -1) to strip the newline, which would fail with a
(args-out-of-range "" 0 -1) exception.
Fix this by only stripping the newline if there actually is one.
Imitated from "Enabling advice" in Emacs lisp manual...
ad-disable-advice by itself only changes the enable flag for a
piece of advice. To make the change take effect in the
advised definition, the advice needs to be activated again.
remaps are a rather unusual keymap consisting of "first key" 'remap
and then "second-key" the remapped-function. Thus we do the
documentation for it separately.
To support key remapping in emacs help we need to know the base keymap
when looking at the remapping. keep track of this while we recurse
down the sub-keymaps in help.
The actual documentation function notmuch-describe-keymap was getting
rather complicated so split out the code for a single key into its own
function notmuch-describe-key.
If the user (or a mode) overrides a keybinding from the common keymap
in one of the modes then both help lines appear in the help screen
even though only one of them is applicable.
Fix this by checking if we already have that key binding. We do this
by constructing an list of (key . docstring) pairs so it is easy to
check if we have already had that binding. Then the actual print help
routine changes these pairs into strings "key \t docstring"
The routines that construct the help page in notmuch-lib rely on
match-data being preserved across some fairly complicated code. This
is currently valid but will not be when this series is finished. Thus
place everything between the string-match and replace-match inside a
save-match-data.
A standard way to unset a key binding is local-unset-key which is equivalent to
(define-key (current-local-map) key nil)
Currently notmuch-help gives an error and fails if a user has done this.
To fix this we only add a help line if the binding is non-nil.
The functions referred to in the documentation for this variable were
replaced by the unified `notmuch-poll-and-refresh-this-buffer' in
21474f0e. Update the documentation to reflect the new function.
(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!)
