Previously, all visibility in show buffers for headers, message
bodies, and washed text was specified by generating one or more
symbols for each region and creating overlays with their 'invisible
property set to carefully crafted combinations of these symbols.
Visibility was controlled not by modifying the overlays directly, but
by adding and removing the generated symbols from a gigantic buffer
invisibilty spec.
This has myriad negative consequences. It's slow because Emacs'
display engine has to traverse the buffer invisibility list for every
overlay and, since every overlay has its own symbol, this makes
rendering O(N^2) in the number of overlays. It composes poorly
because symbol-type 'invisible properties are taken from the highest
priority overlay over a given character (which is often ambiguous!),
rather than being gathered from all overlays over a character. As a
result, we have to include symbols related to message hiding in the
wash code lest the wash overlays un-hide parts of hidden messages. It
also requires various workarounds for isearch to properly open
overlays, to set up buffer-invisibility-spec for
remove-from-invisibility-spec to work right, and to explicitly refresh
the display after updating the buffer invisibility spec.
None of this is necessary.
This patch converts show and wash to use simple boolean 'invisible
properties and to not use the buffer invisibility spec. Rather than
adding and removing generated symbols from the invisibility spec, the
code now directly toggles the 'invisible property of the appropriate
overlay. This speeds up rendering because the display engine only has
to check the boolean values of the overlays over a character. It
composes nicely because text will be invisible if *any* overlay over
it has 'invisible t, which means we can overlap invisibility overlays
with abandon. We no longer need any of the workarounds mentioned
above. And it fixes a minor bug for free: now, when isearch opens a
washed region, the button text will update to say "Click/Enter to
hide" rather than remaining unchanged.
Previously refreshing the notmuch show buffer did not remove overlays
which meant that if the user refreshed a message with images the
images would remain and then the new text was added after.
One might have guessed that erase-buffer would have removed them but
it seems not. Thus force the removal of overlays with remove-overlays.
This function is also used by pick so split it out in preperation for
moving to lib. In fact, pick and show want a slightly different
combination of name and email on return so make the separated function
return them as a pair, and let show or pick extract the combination
they want from that.
The macro with-current-notmuch-show-message executes command
`notmuch show --format=raw id:...` which just outputs the contents
of the mail file verbatim (into temporary buffer). In case e.g. utf-8
locale is used the temporary buffer has buffer-file-coding-system as
utf-8. In this case Emacs converts the data to multibyte format, guessing
that input is in utf-8.
However, the "raw" (MIME) message may contain octet data in any other
8bit format, and as no (MIME-)content spesific handling to the message
is done at this point, conversion to other formats may lose information.
By setting coding-system-for-read 'no-conversion drops the conversion part
and makes this handle input as notmuch-get-bodypart-internal() does.
This marks the broken test in previous change fixed.
icalendar-import-buffer can fail by an error signal (which have been
witnessed) but according to its docstring it can also return nil
when failing (it returns t when succeeding).
Now that the error is caught by the caller of notmuch-show-inset-part-*
functions in case icalendar-import-buffer returns nil an explicit
error is signaled and unwind-protect takes care of deleting the
temporary file (just in case, it is usually not written to the fs yet).
notmuch-get-bodypart-content provides raw data to its caller so
that it can be stored verbatim whenever needed. icalendar functions
expect Emacs to do EOL conversion for the data given to these. Therefore
it the CRLF -> LF conversion is now done explicitly.
The calls to private functions icalendar--convert-ical-to-diary and
icalendar--read-element are replaced with call to public function
icalendar-import-buffer.
This regexp agrees with Xapian query syntax much more closely, though
we specifically disallow various cases that would be confusing in the
context of an email body (e.g., punctuation at the end of an id: link
is not considered part of the id: link because it's probably part of
the surrounding text).
In particular, this handles id: links that are not surrounded by
quotes much better, which stash is much more likely to generate now
that we don't quote id's that don't need to be quoted. It also
handles quoted id: links better.
We update the buttonization test to reflect the new pattern.
When inserting of email bodypart failes, insert a failure message
to the buffer (and continue) instead of halting the insertion of
the rest of that email thread in question.
Since marking a message as read can now be a user customized set of
tag changes, make reversing this easier. Allow a prefix argument to
notmuch-show-mark-read to reverse the marking as read, similar to the
unarchiving in notmuch-show-archive-message.
While at it, update the relevant documentation to match that of other
automatic tagging (i.e. archive and reply).
Add support for customization of the tag changes that are applied when
a message or a thread is archived. Instead of hard-coded removal of
the "inbox" tag, the user can now specify a list of tag changes to
perform.
The `notmuch-show-mark-read-tags' lists tags that are to be applied when
message is read. By default, the only value is "-unread" which will remove
the unread tag. Among other uses, this variable can be used to stop
notmuch-show from modifying tags when message is shown (by setting the
variable to an empty list).
Previously, notmuch-show-previous-message would move to the beginning
of the message before the message containing point. This patch makes
it instead move to the previous message *boundary*. That is, if point
isn't already at the beginning of the message, it moves to the
beginning of the current message. This is consistent with
notmuch-show-next-message, which can be thought of as moving to the
next message boundary. Several people have expressed a preference for
this.
The pipe message function (when used with a prefix) uses a search of
the form "id:<id1> or id:<id2>" etc. Since the user says precisely
which messages are wanted by opening them it should not use excludes.
Previously the elide messages code got the entire-thread from
notmuch-show.c and then threw away all non-matching messages. This
version calls notmuch-show.c without the --entire-thread flag so
it never receives the non-matching messages in the first place.
This makes it substantially faster.
Allow the user to pipe the attachment somewhere. Bound to '|' on the
attachment button.

Quote non-text parts nicely by displaying them with mm-display-part
before calling message-cite-original to quote them. HTML-only emails
can now be quoted correctly. We re-use some code from notmuch-show
(notmuch-show-mm-display-part-inline), which has been moved to
notmuch-lib.el.
Mark the test for this feature as not broken.
The main change here is to modify argument parsing so as to not force
tag-changes to be a list, and to let notmuch-tag handle prompting the
user when required. doc strings are also updated and cleaned up.
Tagging functions are used in notmuch.el, notmuch-show.el, and
notmuch-message.el. There are enough common functions for tagging
that it makes sense to put them all in their own library.
No code is modified, just moved around.
When using the spacebar to scroll through a thread, hitting 'space'
when the bottom of the last message is visible should take the cursor
to the end of the buffer rather than immediately archiving the thread
and moving to the next thread.
Currently emacs show does not open matching but excluded
messages. This is normally the desired behaviour but is probably not
ideal if only excluded messages match. This patch opens all the
matching (necessarily excluded) messages in this case and goes to the
first one.
A previous patch [0] replaced blank subject lines with '[No Subject]'
in search and show mode. Apparently this was needed to circumvent
some bug in the printing code, but there was no need for it search or
show, and it is definitely not desirable, so we undo it here (a revert
is no longer feasible). We should not be modifying strings in the
original message without good reason, or without a clear indication
that we are doing so, neither of which apply in this case. For
further discussion see [0].

Show has to set --exclude=false to deal with cases where it is asked
to show a single excluded message. It uses JSON so it can easily pass
the exclude information to the user.
This adds a lib function to turn a message ID into a properly escaped
message ID query and uses this function wherever we previously
hand-constructed ID queries. Wherever this new function is used,
documentation has been clarified to refer to "id: queries" instead of
"message IDs".
This fixes the broken test introduced by the previous patch.
Use the new JSON reply format to create replies in emacs. Quote HTML
parts nicely by using mm-display-part to turn them into displayable
text, then quoting them with message-cite-original. This is very
useful for users who regularly receive HTML-only email.
Use message-mode's message-cite-original function to create the
quoted body for reply messages. In order to make this act like the
existing notmuch defaults, you will need to set the following in
your emacs configuration:
message-citation-line-format "On %a, %d %b %Y, %f wrote:"
message-citation-line-function 'message-insert-formatted-citation-line
The tests have been updated to reflect the (ugly) emacs default.
Show mode will recognize the exclude flag by not opening excluding
messages by default, and will start at the first matching non-excluded
message. If there are no matching non-excluded messages it will go to
the first matching (necessarily excluded) message.
It is not clear whether the term "thread" refers to the thread in the
database or to the thread currently shown in a buffer. Those two
meanings may refer to different sets of messages, e.g. when a new email
is added to the database while the buffer shows the state before the new
email arrived.
This patch replaces the term thread with the term current buffer, which
is hopefully less ambiguous.
The behavior of the header line in show-mode changed from showing the
subject of the first open message to showing the subject of the first
message in 4d77f18b. Update a comment to reflect this.
Consensus seems to be that people prefer that refreshing show buffers
retains state by default, rather than resetting it by default. This
turns out to be the case in the code, as well. In fact, there's even
a test for this that's been marked broken for several months, which
this patch finally gets to mark as fixed.
If we retain state while refreshing a show buffer, it should not mark
any messages read since it's not a navigation operation (it especially
shouldn't mark the first message matching the query read, which is
what it did previously). If the user or caller requests that refresh
reset the state of the buffer, then we consider that a navigation
operation, so we do mark the message under point after the refresh
read.
This is implemented by moving responsibility for initial positioning
and read-marking out of notmuch-show-worker and into its caller.
Since notmuch-show-worker is now exclusively about building the show
buffer, we rename it to notmuch-show-build-buffer.

Code by David Edmondson <dme@dme.org>
The notmuch-show view refresh function (`notmuch-show-refresh-view',
bound to "=") accepts an optional RETAIN-STATE argument. The patch
allows to set this argument interactively by using "C-u =".
Recent changes in notmuch-show tagging introduced some code
duplication. The patch cleanups and simplifies
`notmuch-show-archive-thread' function by using
`notmuch-show-tag-all', no longer used function are removed. After
the change, `notmuch-show-archive-thread' function becomes symmetric
with `notmuch-show-archive-message'.
A side effect of these changes is that `notmuch-show-archive-thread'
no longer calls "notmuch tag" for each message in the thread.
With an argument, record and reply the state of the buffer during
`notmuch-show-refresh-view'.
In this context, "state" is defined as:
- the open/closed state of each message,
- the current message.
Traditional use of refresh with the = key does not retain the
state. The recently introduced toggle commands ($, !, < and >) do
retain the state.
Very deeply indented content is sometimes difficult to
read (particular for something like patches). Allow the indentation of
the content to be toggled with '<'.
Indentation of the header lines is not affected, so it remains
possible to see the structure of the thread.
The current behaviour (all messages shown, non-matching collapsed)
is retained as the default. Type '!' to switch to showing only
the matching messages - non-matching messages are not available.
'!' will switch back to showing everything.
Re-work the existing crypto switch toggle to be based on a persistant
buffer-local variable.
To allow this, modify `notmuch-show-refresh-view' to erase and re-draw
in the current buffer rather than killing the current buffer and
creating a new one. (This will also allow more per-buffer behaviour in
future patches.)
Add a binding ('$') to toggle crypto processing of the current buffer
and remove the prefix argument approach that achieves a similar
result.
