6d6006bea9 emacs: add '?' to some prefix keymaps to describe its bindings
Added function notmuch-subkeymap-help to describe keybindings of a
subkeymap (eg after . or c in notmuch-search and notmuch-show).

b5f93cc0db emacs: help: add a special function to deal with remaps
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.

8141555d25 emacs: help: add base-keymap
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.

141f3813d8 emacs: help: split out notmuch-describe-key as a function
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.

9d0174b11c emacs: help: remove duplicate bindings
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"

6f616bd733 emacs: help: save-match-data
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.

a5ecdf390e emacs: help: check for nil key binding
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.

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.

ddc44ae0d0 emacs: Move `notmuch-call-notmuch-process' to notmuch-lib
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.

fd656d7683 emacs: Move ?, q, s, m, =, and G to the common keymap
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).

doesn't consider trailing data to be an error, which may or may not be
what we want in the long run.

634914064b emacs: Don't report CLI signals sent by Emacs as errors
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).

a13b388243 emacs: Utilities to manage asynchronous notmuch processes
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).

04725cfbe5 emacs: Record part p-list in a text property
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.

e7ade21d56 emacs: Fix trimming regexp in notmuch-check-exit-status
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.

ab30a846a4 emacs: removed code attempting to support emaces prior to version 23
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.

the changes from the patch email referenced above.

9cf89a3c04 emacs: Combine string faces and combine under existing faces

3ddb4dc806 emacs: Handle all face forms when combining faces
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.

3901bbca2e emacs: show: make buttons select window
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.

401dbebd48 emacs: Use the minibuffer for CLI error reporting
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).

d0ebd6cb53 emacs: Fix bug in resynchronizing after a JSON parse error
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.

f227d63b27 emacs: Work around gnus-inhibit-images bug in mm-shr
Emacs 24's mm-shr HTML email renderer fails to load gnus-art before
referencing gnus-inhibit-images, resulting in a void-variable error
when notmuch attempts to render an HTML email with inline images.
This works around this bug by advising mm-shr to load gnus-art.

mm-shr is the only function outside of gnus-art itself that references
gnus-inhibit-images, so this workaround should be correct.  If this
ever changes, hopefully they will have fixed this bug upstream first.

This fixes the "Rendering HTML mail with images" test for Emacs 24.

60ebc84945 emacs: Use text properties instead of overlays for tag coloring
Previously, tag-based search result highlighting was done by creating
an overlay over each search result.  However, overlays have annoying
front- and rear-advancement semantics that make it difficult to
manipulate text at their boundaries, which the next patch will do.
They also have performance problems (creating an overlay is linear in
the number of overlays between point and the new overlay, making
highlighting a search buffer quadratic in the number of results).

Text properties have neither problem.  However, text properties make
it more difficult to apply multiple faces since, unlike with overlays,
a given character can only have a single 'face text property.  Hence,
we introduce a utility function that combines faces into any existing
'face text properties.

Using this utility function, it's straightforward to apply all of the
appropriate tag faces in notmuch-search-color-line.

889dda3731 emacs: Implement an incremental JSON parser
This parser is designed to read streaming JSON whose structure is
known to the caller.  Like a typical JSON parsing interface, it
provides a function to read a complete JSON value from the input.
However, it extends this with an additional function that
requires the next value in the input to be a compound value and
descends into it, allowing its elements to be read one at a time
or further descended into.  Both functions can return 'retry to
indicate that not enough input is available.

The parser supports efficient partial parsing, so there's no need to
frame the input for correctness or performance.

The bulk of the parsing is still done by Emacs' json.el, so any
improvements or optimizations to that will benefit the incremental
parser as well.

Currently only descending into JSON lists is supported because that's
all we need, but support for descending into JSON objects can be added
in the future.

70ca3444c7 emacs: use 'gnus-decoded in notmuch-mm-display-part-inline ()
When mail message is read from emacs, the message structure
obtained may contain parts which have content included
(`text/plain` for example) and other parts where content is not
included (`text/html` for example).

In case content is included, the string is already available in
emacs' internal format and therefore mm-... functions should not
attempt to do further decoding for the data in temp buffer
provided for it.

Currently when reply buffer is created,
notmuch-mm-display-part-inline () is used to provided quoted reply
content. This change makes the mm-... functions called by it use
'gnus-decoded as charset whenever the content is already available.

File .../emacs-23.3/lisp/gnus/mm-uu.el mentions:
"`gnus-decoded' is a fake charset, which means no further decoding."
