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.

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!)
This adds support for passing a string to write to notmuch's stdin to
`notmuch-call-notmuch-process' and `notmuch-call-notmuch-sexp'. Since
this makes both interfaces a little more complicated, it also unifies
their documentation better.
Previously, this was in notmuch.el, but all of the other notmuch call
wrappers were in notmuch-lib.el. Move `notmuch-call-notmuch-process'
to live with its friends. This happens to fix a missing dependency
from notmuch-tag.el, which required notmuch-lib, but not notmuch.
notmuch-help is in notmuch.el not notmuch-lib.el and this is
incovenient for the way pick/tree uses it. I think lib makes more
sense anyway so move it there.
Authors and subjects can contain embedded, encoded control characters
like "\n" and "\t" that mess up display. Transform control characters
into spaces everywhere we display them in search and show.
The only user-visible effect of this should be that "G" now works in
show mode (previously it was unbound for no apparent reason).
This shared keymap gives us one place to put global commands, which
both forces us to think about what commands should be global, and
ensures their bindings can't diverge (like the missing "G" in show).
This unifies the various refresh and poll-and-refresh functions we
have for different modes. Now all modes bind "=" and "G" (except
show, which doesn't bind "G" for some reason) to
`notmuch-refresh-this-buffer' and
`notmuch-poll-and-refresh-this-buffer', respectively.
Notmuch cli provides all structured data previously provided
in json format now in s-expression format, rendering all current
json functionality obsolete.
This is just like `notmuch-call-notmuch-json', but parses S-expression
output. Note that, also like `notmuch-call-notmuch-json', this
doesn't consider trailing data to be an error, which may or may not be
what we want in the long run.
Previously, when the user killed the search buffer before the CLI
search process had completed, we would report the signal sent by Emacs
to kill the CLI to the user as an error. Fix this by only reporting
error exits if the process buffer is still live. We still report
stderr output regardless in case stderr output was relevant to why the
user killed the search buffer (such as a wrapper script being stuck).
This provides a new notmuch-lib utility to start an asynchronous
notmuch process that handles redirecting of stderr and checking of the
exit status. This is similar to `notmuch-call-notmuch-json', but for
asynchronous processes (and it leaves output processing to the
caller).
This is similar to what we already do with the message p-list, though
we apply the part's text property to the whole part's text, in
contrast with the message p-list, which is (rather obscurely) only
applied to the first character.
For such a simple regexp, this was broken in a very complicated way.
The intent was to strip the newline (and potentially other whitespace)
off the end of the error string so there wasn't an extra newline in
the error signal. However, the regexp was deeply dependent on the
active syntax table and the subtleties of $. We didn't notice this
because all notmuch major modes put ?\n in the whitespace class, which
makes this behaved as intended: the "\\s " matches all newlines, but
by matching the newline character, causes the $ *not* to match
*except* where it matched the empty string at the very end of the
string, which was not followed by a newline.
However, if the syntax table declares ?\n to be non-whitespace
(lisp-mode declares it as endcomment, and is likely to be the mode
you're in when testing functions), then this regexp behaves completely
differently, matching trailing spaces at the end of every line within
the string.
The solution is to say what we mean for whitespace *and* to switch
from $ to \', which matches only the end of the string, rather than
the end of each line. Both are necessary or this will strip away
interior newlines, which is not what we want.
The support for emacs version 22 has not worked at least since
September 2011 when I attempted to use it. I expanded the support in
id:yf6ippgtbn0.fsf@taco2.nixu.fi but that was not enough and then I
found it easier to switch to emacs 23.
In case one wants to resurrect emacs 22 (or earlier!) support, pick
the changes from the patch email referenced above.
This has two benefits: unified error handling, and avoiding tramp's
hooking into shell-command-string.
This seems to be a fix for id:874nguxbvq.fsf@tu-dortmund.de
