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
This improves notmuch-combine-face-text-property to support both
applying faces to strings and to support combining the given face
under existing faces, rather than over.
Previously, notmuch-combine-face-text-property assumed that any
existing face properties of the modified text were already in face
list form. This was true as long as it was the only function
manipulating faces (since it always produced a list form face), but if
anything else has manipulated the face, it was more likely to be
either a face name or a face plist. It also didn't correctly handle
face lists as arguments, even though the doc string claimed it did.
This patch fixes notmuch-combine-face-text-property to handle all face
forms correctly by canonicalizing both the argument face and the
existing faces into list form. This also means we can set the face to
a simpler non-list form if there's no existing face.
Emacs has two button type objects: widgets (as used for saved searches
in notmuch-hello) and buttons as used by parts/citations and id links
in notmuch-show. These two behave subtly differently when clicked with
the mouse: widgets select the window clicked before running the
action, buttons do not.
This patch makes all of these behave the same: clicking always selects
the clicked window. It does this by defining a notmuch-button-type
supertype that the other notmuch buttons can inherit from. This
supertype binds the mouse-action to select the window and then
activate the button.
We recently switched to popping up a buffer to report CLI errors, but
this was too intrusive, especially for transient errors and especially
since we made fewer things ignore errors. This patch changes this to
display a basic error message in the minibuffer (using Emacs' usual
error handling path) and, if there are additional details, to log
these to a separate error buffer and reference the error buffer from
the minibuffer message. This is more in line with how Emacs typically
handles errors, but makes the details available to the user without
flooding them with the details.
Given this split, we pare down the basic message and make it more
user-friendly, and also make the verbose message even more detailed
(and more debugging-oriented).
This slightly changes the output of an existing test since we now
report non-zero exits with a pop-up buffer instead of at the end of
the search results.
This checks for non-zero exit status from JSON CLI calls and pops up
an error buffer with stderr and stdout. A consequence of this is that
show and reply now handle errors, rather than ignoring them.
This provides library functions for unified handling of errors from
the notmuch CLI. Follow-up patches will convert some scattered error
handling to use this and add error handling where we currently ignore
errors.
Previously, if the input stream consisted only of an error message,
notmuch-json-begin-compound would signal a (wrong-type-argument
number-or-marker-p nil) error when reaching the end of the error
message. This happened because notmuch-json-scan-to-value would think
that it reached a value and put the parser into the 'value state.
Even after notmuch-json-begin-compound signaled the syntax error, the
parser would remain in this state and when the resynchronization logic
reached the end of the buffer, the parser would fail because the
'value state indicates that characters are available.
This fixes this problem by restoring the parser's previous state if it
encounters a syntax error.

emacs: Rip out all of the notmuch-folder code.
This lets us simplify the notmuch-saved-searches code slightly.
Currently, we only properly escape stashed id queries, but there are
other places where the Emacs UI constructs queries for boolean terms.
Since this escaping function is meant to be used in other places, it
avoids escaping strings that don't need escaping.
