Since only the first line of the documentation is shown by the
help command, it is confusing when "x" and "a" seem to have the same
binding in show-mode. This commit makes the two function documentations
first lines different and (hopefully) clearer.
Add a new binding when looking at messages, B, that prompts with a
list of URLs found in the current message, if any. Open the one that
is selected in a browser.
amended by db: s/--browse-urls/-browse-urls/
`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.
Correct URLs that have crept into the notmuch codebase with http://
when https:// is possible.
As part of this conversion, this changeset also indicates the current
preferred upstream URLs for both gmime and sup. the new URLs are
https-enabled, the old ones are not.
This also fixes T310-emacs.sh, thanks to Bremner for catching it.
Dynamically bind enriched-decode-display-prop when inserting
text/enriched part. This complements commit 9b05823838 for
emacs versions before 24.4 which do not have advice-add
functionality.
Since emacs 25.3 this particular bug is fixed.
Switch to a local version of enriched-decode-display-prop if we
encounter a text/enriched part. This is to mitigate
https://bugs.gnu.org/28350. Normally it would be prudent to remove the
override afterwards, but in this case just leave it in.
Notes from db:
This doesn't disable text/enriched, just one feature of it.
The queries "" and "*" are special cased in the notmuch library to
match all messages, but only if they're the entire query. They can't
be combined with other queries, such as "* AND foo", in which case
they "leak" down to the Xapian query parser.
Notmuch show and tree buffers inadvertently combine the thread query
with said special queries, causing incorrect collapsing of
messages. Handle the special queries specially. We already do a
similar thing in notmuch-search-filter.
Emacs' major modes can facilitate navigation in their buffers by
supporting Imenu. In such major modes, launching Imenu (M-x imenu)
makes Emacs display a list of items (e.g., function definitions in a
code buffer). Selecting an item from this list moves point to this
item.
This patch adds Imenu support to both notmuch-show and notmuch-search
buffers:
* in notmuch-show, Imenu will present a list of all messages in the
currently visible thread;
* in notmuch-search, Imenu will present a list of all messages in the
search buffer.
Gnus seems to display application/zip and application/tar by
default. This doesn't seem desirable so we override it.
We only override if the user has not customized
mm-inline-override-types themselves.
Provide functionality to resume editing a message previously saved with
notmuch-draft-save, including decoding the X-Notmuch-Emacs-Secure
header.
Resume gets the raw file from notmuch and using the emacs function
mime-to-mml reconstructs the message (including attachments).
'e' is bound to resume a draft from show or tree mode.
notmuch-show--build-buffer now queries a list of queries built by the
former. This simplifies the logic. It also provides an easy place to
experiment with alternate sets of queries for given notmuch-show-*
variables (e.g. users can use advice-add to do so in a surgical way).
This updates all windows displaying a notmuch-show buffer when the
buffer refresh function is called.
Each window displaying a notmuch-show buffer has its own currently
displayed message based on the (point) location. We store the state
of all displayed windows when refreshing a notmuch-show buffer and
re-apply the current shown message (point) for all windows.
Implementation note: Each window has it's own (point) value, besides
the buffer's (point) value. Sometimes these values are identical like
in the case where a single window displays a buffer. When multiple
windows display a buffer, (point) returns each window's specific value.
What we are storing in this changeset is the window values not the
buffer point values. The buffer's point is returned only if no window
is displaying the buffer, a case we do not care about here.

This seems to fix a problem with emacs 25 creating partial buttons by
calling n-s-b-l with a region that does not include the whole button.
I'm not 100% sure it's legit to act outside the region passed by
jit-lock, but goto-address-fontify-region (where I borrowed the code
from) already does this, so this patch to not make things worse.
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.
This allows the user to override the mime-type of a part in the show
buffer. This takes the simple option of displaying the part with the
specified mime-type in its own buffer (in view mode). This avoids
further complicating the part handling code.
Bound to ". m" (i.e., m in the part map). Then the user can either
enter a mime-type (with completion to all mime types that mailcap (and
thus notmuch) knows about, or press return for the default choice of
text/plain.
Previously if a marking read tag change (i.e., removing the unread
tag) failed for some reason, such as a locked database, then no more
mark read tag changes would be attempted in that buffer.
This handles the error more gracefully. There is not much we can do
yet about dealing with the error itself, and marking read is probably
not important enough to warrant keeping a queue of pending changes or
anything.
However this commit changes it so that
- we do try and make future mark read tag changes.
- we display the tag state correctly: i.e. we don't display the tag as
deleted (no strike through)
- and since we know the tag change failed we can try to mark this
message read in the future. Indeed, since the code uses the
post-command hook we will try again on the next keypress (unless the
user has left the message).
We indicate to the user that these mark read tag changes may have
failed in the header-line.
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.
This binding is similar to mutt's, which is
bind {mode} b "bounce-message" # remail a message to another user
where {mode} is 'index', 'pager' or 'attach'.
The new function notmuch-show-message-resend re-sends
message to new recipients using #'message-resend.
Recipients are read from minibuffer as a comma-separated
string (with some keyboard support including tab completion).
Final confirmation before sending is asked.
When no decryption or signature examination is
happening (i.e. `notmuch-crypto-process-mime' is `nil') insert buttons
that indicate this, rather than remaining silent.
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.
Add a customizable function specifying which parts get a header when
replying, and give some sensible possiblities. These are,
1) all parts except multipart/*. (Subparts of a multipart part do
receive a header button.)
2) only included text/* parts.
3) Exactly as in the show buffer.
4) None at all. This means the reply contains a mish-mash of all the
original message's parts.
In the test suite we set the choice to option 4 to match the
previous behaviour.
This allows callers of notmuch-show-insert-bodypart to use a `let'
binding to override the default function for specifying when part
headers should be inserted.
We also add an option to never show part buttons which will be used by
the test suites for the reply tests.
If the basic query passed to `notmuch-show' generates no results, ring
the bell and inform the user that no messages matched the query rather
than displaying an empty buffer and showing an obscure error.
Similarly when refreshing a `notmuch-show' buffer and no messages match.
notmuch-show-view-raw-message() re-uses buffer created with same
name (same Message-Id:) but it did not erase it before filling.
If this ever happened, there were duplicated (potentially overlapping)
content in the buffer. Now this is fixed.
Apparently since emacs 24.5 the (view-buffer) makes the buffer read-only;
so this problem would not have happened there, just that
notmuch-show-view-raw-message() failed. This is fixed by setting
inhibit-read-only t before erasing and filling the buffer. The emacs 24.5
feature having raw message buffer read-only is also now explicitly set to
the buffer so the same experience is available with emaces < 24.5.
Commit e26d767897 changed the
fontification of the body associated with the From header to
message-header-from. However, that face is non-existent, and in
message.el (message-font-lock-keywords) the From-header falls through
and is attributed the message-header-other face.
This commit removes the fontification of the [Ff]rom header in
notmuch-show-mode in order to fontify it using the message-header-other
face.
This only affects non-default configurations where
notmuch-message-headers is set to display From.
Currently notmuch-show-max-text-part-size is 10000 which means some
relatively normal messages have all parts hidden by default. Increase
this to 100000 by default.
The setting was introduced to alleviate problems with notmuch being
very slow on large threads. Users hitting these problems may wish to
customize this variable to something smaller (like 10000).
Show the current thread with a different filter (i.e., open messages
in the thread matching the new query).
Bound to 'l' for "limit".
Note that it is not the same as filter in search mode as it replaces
the existing query rather than ANDing with it (but it does keep the
thread-id part of the query).
Separate out a notmuch-show-goto-msg-id sub-function from
notmuch-show-apply-state. There should be no functional change but the
next patch will call the new function.
notmuch-show can be slow displaying large attachments so hide them by
default. The default maximum size is 10000 bytes/characters but it is
customizable.
Note that notmuch-show-insert-bodypart is also called from the reply
code so we need to be a little careful.
Besides generally cleaning up the code and separating the general
content ID handling from the w3m-specific code, this fixes several
problems.
Foremost is that, previously, the code roughly assumed that referenced
parts would be in the same multipart/related as the reference.
According to RFC 2392, nothing could be further from the truth:
content IDs are supposed to be globally unique and globally
addressable. This is nonsense, but this patch at least fixes things
so content IDs can be anywhere in the same message.
As a side-effect of the above, this handles multipart/alternate
content-IDs more in line with RFC 2046 section 5.1.2 (not that I've
ever seen this in the wild). This also properly URL-decodes cid:
URLs, as per RFC 2392 (the previous code did not), and applies crypto
settings from the show buffer (the previous code used the global
crypto settings).
`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.
We set header-line-format to the message subject, but if the subject
contains percents, the next character is interpreted as a formatting
control, which is not desired.
`with-current-notmuch-show-message' applies a `no-conversion' coding
system when reading a raw message from notmuch. That coding system
should _not_ be applied when the body of the macro is evaluated, as it
can cause file operations used during that evaluation to incorrectly
apply the `no-conversion' coding system.
This was discovered when a user's .signature file contained non-ASCII
characters. When a message is forwarded, the `no-conversion' coding
system was applied to the reading of the .signature file, resulting in
raw rather than UTF-8 interpretation of the data.
tree overrides notmuch-show-get-prop so that it can use many of the
utility function directly. Now that tree is in mainline the version
from tree can be moved to show and the original overridden show
version dropped.
This adds the current query as a "default value" to
notmuch-read-qeury. The default value is available via a down-arrow as
opposed to history which is available from the up arrow.
Note if a user presses return in the minibuffer this value is not
returned.
The implementation is simple but notmuch-read-query could be called
via notmuch-search/notmuch-tree etc from any buffer so it makes sense
to put the decision of how to extract the current query in
notmuch-read-query rather than in each of the callers.
Add a function for updating seen messages to the
post-command-hook. This function calls a customizable (by eg
defcustom) function with parameters the start and end of the current
window and that function can decide what to mark read based on that
and the current point.
Since this is in the post-command-hook it should get called after most
user actions (exceptions include user resizing the window) so it
should be possible to make sure the seen status gets updated whether
the user uses notmuch commands like next-message or normal emacs
commands like scroll-up.
It removes all of the old mark read/seen points but introduces a
simple example function that just marks the current message read if it
is open. This function has one small subtlety: it makes sure it
doesn't mark the same message read twice (in the same instance of the
same buffer); otherwise the post-command-hook makes it impossible for
a user to manually mark a message unread.
This fixes the current bugs (imo) that closed messages can be marked
read, and that opening a closed message does not mark it read.
Another advantage of using the post-command-hook any programmatic use
with point passing through a message will not mark it read.
Some archives may use a more complicated scheme for referring to
messages than just concatenated url and message-id. In particular,
patchwork requires a query to translate message-id to a patchwork
patch id. Allow functions in notmuch-show-stash-mlarchive-link-alist
to facilitate this.
For example, one could use something like this for patchwork.
(lambda (message-id)
(concat
"http://patchwork.example.com/patch/"
(nth 0
(split-string
(car (last (process-lines "pwclient" "search" "-n" "1"
"-m" (concat "<" message-id ">"))))))))
Previously, even if debug-on-error was non-nil, the debugger would not
trap on part renderer errors. This made debugging part renderer bugs
frustrating, so let the debugger trap these errors.
This allows (and requires) the original-tags to be passed along with
the current-tags to be passed to notmuch-tag-format-tags. This allows
the tag formatting to show added and deleted tags.By default a removed
tag is displayed with strike-through in red (if strike-through is not
available, eg on a terminal, inverse video is used instead) and an
added tag is displayed underlined in green.
If the caller does not wish to use the new feature it can pass
current-tags for both arguments and, at this point, we do exactly that
in the three callers of this function.
Note, we cannot tidily allow original-tags to be optional because we would
need to distinguish nil meaning "we are not specifying original-tags"
from nil meaning there were no original-tags (an empty list).
We use this in subsequent patches to make it clear when a message was
unread when you first loaded a show buffer (previously the unread tag
could be removed before a user realised that it had been unread).
The code adds into the existing tag formatting code. The user can
specify exactly how a tag should be displayed normally, when deleted,
or when added.
Since the formatting code matches regexps a user can match all deleted
tags with a ".*" in notmuch-tag-deleted-formats. For example setting
notmuch-tag-deleted-formats to '((".*" nil)) tells notmuch not to show
deleted tags at all.
All the variables are customizable; however, more complicated cases
like changing the face depending on the type of display will require
custom lisp.
Currently this overrides notmuch-tag-deleted-formats for the tests
setting it to '((".*" nil)) so that they get removed from the display
and, thus, all tests still pass.
This modifies `notmuch-tag-format-tag' to treat the keys of
`notmuch-tag-formats' as (anchored) regexps, rather than literal
strings. This is clearly more flexible, as it allows for prefix
matching, defining a fallback format, etc. This may cause compatibility
problems if people have customized `notmuch-tag-formats' to match tags
that contain regexp specials, but this seems unlikely.
Regular expression matching has quite a performance hit over string
lookup, so this also introduces a simple cache from exact tags to
formatted strings. The number of unique tags is likely to be quite
small, so this cache should have a high hit rate. In addition to
eliminating the regexp lookup in the common case, this cache stores
fully formatted tags, eliminating the repeated evaluation of potentially
expensive, user-specified formatting code. This makes regexp lookup at
least as fast as assoc for unformatted tags (e.g., inbox) and *faster*
than the current code for formatted tags (e.g., unread):
inbox (usec) unread (usec)
assoc: 0.4 2.8
regexp: 3.2 7.2
regexp+caching: 0.4 0.4
(Though even at 7.2 usec, tag formatting is not our top bottleneck.)
This cache must be explicitly cleared to keep it coherent, so this adds
the appropriate clearing calls.
Currently notmuch-show-pipe-message runs the command in the working
directory of the *notmuch-pipe* buffer if it exists, and the current
buffer's working directory (which is inherited to the new
*notmuch-pipe* buffer) otherwise. This is all very surprising to the
user, and it's difficult to know or change where the command will be
run.
Always use the current show buffer's working directory for piping. The
user can check that with M-x pwd and change it with M-x cd. This is
consistent with notmuch-show-pipe-part.
Searching by Message-Id no longer works via the old mail-archive.com
API, though I have contacted them in hopes that they restore it to
prevent dead links. Anyway, the new API is cleaner.

In emacs 24.3+ the stdout/stderr from externally displaying an
attachment gets inserted into the show buffer. This is caused by
changes in mm-display-external in mm-decode.el.
Ideally, we would put this output in the notmuch errors buffer but the
handler is called asynchronously so we don't know when the output will
appear. Thus if we put it straight into the errors buffer it could get
interleaved with other errors. Also we can't easily tell when we
have got all the error output so can't wait until the process is complete.
One solution would be to create a new buffer for the stderr of each
attachment viewed. Again, since we can't tell when the process has
finished, we can't close these buffers automatically so this will
leave lots of buffers around.
Thus we add a debug variable notmuch-show-attachment-debug: it this is
non-nil we create a new buffer for each viewer; if this variable is
nil we just use a temp buffer which means all error output is
discarded (this is the same behaviour as with emacs pre 24.3).
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.
This modifies all tagging operations in show to call
`notmuch-read-tag-changes' in their interactive specification to input
tag changes, rather than depending on lower-level functions to prompt
for tag changes regardless of their calling context.
Besides being more Elispy and providing a more consistent programmatic
API, this enables callers to provide two call site-specific pieces of
information: an appropriate prompt, and the set of visible tags. The
prompt lets us differentiate * from +/-. Providing visible tags
enables a more consistent user experience than retrieving the
(potentially different) tags from the database, and avoids a
round-trip to the CLI and database.
Currently notmuch-show looks at the prefix-arg directly via
current-prefix-arg. This changes it to use the interactive
specification.
One test (for elide-toggle functionality) set the prefix arg
directly. Update this test to set the new argument directly.
This improves the function documentation for many interactive
commands, either by improving their documentation string where the
improvement also makes sense for programmatic use or by adding a
'notmuch-doc property where it doesn't.
For nearly all commands that support a prefix argument, this adds a
'notmuch-prefix-doc property to document their prefixed behavior This
omits prefix documentation for a few commands where I thought the
prefixed behavior was too obscure (or too complex to fit in one line).
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.
When text/html parts include images as multipart/related and the
text/plain alternative is used these images can be completely hidden
with no easy way to access them or even find out that they are there.
Make notmuch-show-insert-part-multipart/related add buttons for all
parts, the first one visible the rest hidden.
The lazy part handler had a bug that it allowed the button to be
toggled to be specified. During toggling it needs to save and restore
the text-properties for the button but it actually saved the text
properties at point rather than from the button.
In almost all cases this didn't matter as as point had the same text
properties as the button. However, it is a bug and did cause incorrect
behaviour in some cases: see id:87txhz14z6.fsf@qmul.ac.uk for details.
In reply, insert quotable parts using notmuch-show-insert-bodypart
instead of calling notmuch-mm-display-part-inline directly to render
the quoted parts as they are rendered in show view.
We use a temp buffer to not leak text properties from the show
renderer into the reply. This way we also don't need to worry about
narrowing or point placement. Credits to Mark Walters
<markwalters1009@gmail.com> and Austin Clements <amdragon@MIT.EDU> for
getting this part straight.
The notable change is that replies to text/calendar parts quote the
pretty printed output of icalendar-import-buffer rather than the ugly
raw vcalendar.
notmuch-show.el and notmuch.el had 3 duplicate, identical functions:
notmuch-foreach-mime-part, notmuch-count-attachments and
notmuch-save-attachments. Now these functions in notmuch-show.el
are replaced with declare-functions pointing to "notmuch"(.el).
Notmuch puts attachments in as declared content-type except when the
content-type is application/octet-stream it tries to guess the type
from the filename/extension. This means that viewing a pdf (for
example) which is sent as application/octet-strem invokes the pdf
viewer rather than just offering to save the part.
Recent changes to the attachment handling (commit 1546387d) changed
(broke) this. This patch stores the calculated mime-type with the part
and changes the attachment part handlers can use it instead.
Notmuch cli provides all structured data previously provided
in json format now in s-expression format, rendering all current
json functionality obsolete.
This removes the v command, since we now have much nicer part commands,
and deprecates the underlying notmuch-show-view-all-mime-parts. This
also means that people who try using the old unprefixed 'v' command on
a part button will no longer be greeted by ALL of their parts popping
up.
Previously the query string for piping a message to a command was
"Pipe message to command: " regardless of whether the function was
called with a prefix argument (which pipes all open messages to the
command). This patch modifies the `interactive' command to reflect
this.
This adds the actual code to do the lazy insertion of hidden parts.
We use a memory inefficient but simple method: when we come to insert
the part if it is hidden we just store all of the arguments to the
part insertion function as a button property. This means when we want
to show the part we can just resume where we left off.
One thing is that we can't tell if a lazy part will produce text until
we try to render it so when unhiding a part we check to see if it
rendered; if not we invoke the default part handler (e.g. an external
viewer).
Also, we would like to insert the lazy part at the start of the line
after the part button. But if this line has some text properties
(e.g. the colours for a following message header) then the lazy part
gets these properties. Thus we start at the end of the part button
line, insert a newline, insert the lazy part, and then delete the
extra newline at the end of the part.
Previously, whether a part was hidden or shown was recorded in the
invisibility/visibility of the part overlay. Since we are going to
have lazily rendered parts with no overlay store the hidden/shown
state in the part button itself.
Additionally, in preparation for the invisible part handling move the
actual hiding of the hidden parts to insert-bodypart from
create-part-overlays.
Finally, we will need to know whether a part-insertion has done
anything (it won't if the invisible part cannot be displayed by emacs)
so we slightly rejig the code order in
notmuch-show-toggle-part-invisibility to make it easier for the
function to set an appropriate return value.
Previously each of the part insertion handlers inserted the part
button themselves. Move this up into
notmuch-show-insert-bodypart. Since a small number of the handlers
modify the button (the encryption/signature ones) we need to pass the
header button as an argument into the individual part insertion
handlers. However, the declared-type argument was only used for the
text for the part buttons we can now omit it.
The patch is large but mostly simple. The only things of note are that
we let the text/plain handler applies notmuch-wash to the whole part
including the part button. In particular, notmuch-wash removes leading
blank lines from a text/plain part, but since the button is counted as
part of the part this does not happen with text/plain buttons that
have a button. This is probably a bug in notmuch-wash but changing it
does make several tests fail (that rely on this blank line) so, for
the moment, keep the old behaviour.
Earlier patches have moved the handling of wash fake inline patch
parts to insert-bodypart so we can drop the function
notmuch-show-insert-part-inline-patch-fake-part
Previously, we simply called pushnew to add :notmuch-part to the
front-sticky and rear-nonsticky text property lists. This works if
these are nil or lists, but they can also have the value t, meaning
that all properties are front-sticky/rear-nonsticky. In this case,
pushnew will signal an error because t is not a list. We never set
these properties to t ourselves, but since we apply these property
changes over arbitrary renderer output, we have to deal with this
possibility.
