In search mode some messages don't match the search criteria. Show

In the common case that a user only has one FCC (save outgoing mail in

such as "Sent" in the notmuch-fcc-dirs variable. More complex options,
depending on a users email address, are possible and described in the
variable customization help text.
The whole function notmuch-fcc-header-setup has been cleaned up a

- Minor layout improvements.
The fcc code would only initialize if notmuch-fcc-dirs was set. This was
a problem if you reset the variable, or added the variable later during
initialization. Now we always add the fcc hook, but it doesn't do
anything unless notmuch-fcc-dirs are set.
Add a (require 'notmuch-message) to notmuch.el. This is for functions that
specifically target message mode (and, in the future, notmuch-message
mode).
Add `notmuch-message-mark-replied', a function for automatically tagging
replied messages with user-defined tags. The tags (which can be either
added or removed) can be customized with the customization variable
`notmuch-message-replied-tags'. This is a simple list of strings. Any
string prefaced with a "-" will be removed; any string prefaced with a "+"
(or neither "+" nor "-") will be added.
This adds a new file notmuch-message.el, for functions which target
message mode (and in the future, notmuch-message mode). Based on some
conversation, notmuch-message.el will probably end up subsuming
notmuch-mua.el, but until we figure out exactly how we want to do that,
they will remain separate files.

The fix in 1e18711543 broke end-of-row

improve the readability of the matrix reflection code to hasten future
debugging.
If the 'all tags' section of the hello buffer will not be shown, don't
consider those tags when determining the number of saved searches that
can be displayed on a single line.
Re-working the saved search/tag insertion to buttonize only the name
of the saved search/tag plus one space broke the calculation of how
much filler is required to complete the column, resulting in lines
wider than the window.
It's possible that the user has instructed message-mode to use some
other separator. If so, then that's what we should look for when
looking for the signature.
Thanks to David Edmondson <dme@dme.org> for pointing this out.
If the user specifies a maildir that does not exist, prompt the user to
see whether a maildir should be created. This will fail, with the
relevant explanation, if the location is not writable, or if a file
already exists in that location. If the location is a dir, but not a
maildir, this will add /tmp/cur/new to it.
Throw an error after the maildir is generated but before the message
is sent. This change allows the user to edit the maildir if it fails,
so that it will point to a correct place.
Note that this changes the previous behavior which always overwrote
the existing Fcc line. Now, an Fcc line is only auto-generated if
there isn't one already there.
The ideal change would be to prompt to create a maildir. This should
enable a place for doing that in a future patch.
The complete-string matching of commit
f2ebe3ac44
defeats the substitution of partial search
strings when the user manually types a
long search string that just happens to
partially match a saved search.
For example, typing "tag:inbox and not tag:foo"
should result in "[inbox] and not tag:foo" but
this has been broken since that commit.
As a compromise between this feature and what the
commit was trying to achieve, we now reverse the
saved-searches list before looking for a match.
This happens to work for me, but won't necessarily
work in general.
What we really want is the longest match, but rassoc-if
just gives us the first match. All of this is just about
creating slightly nice search-buffer names. So if anyone
really cares about making the names *even* nicer, then
they could improve this further.
I happen to have a lot of saved searches that are variants of the
tag:inbox search, (such as "tag:inbox and tag:notmuch"). The logic for
these was always matching inbox first, resulting in "[ inbox ] and
tag:notmuch" rather than "notmuch" as desired.
Anchor the regular expression on both ends to make it look harder for
the better match.
We are asserting that the new notmuch-hello implementation, (available
by just calling `notmuch') is just as easy to use as the old
notmuch-folder. So let's remove what's now a largely redundant
implementation.
To make this transition easier, we are still supporting the
notmuch-folders variable name, and we still provide `notmuch-folder'
as an alias which can be invoked to get the new notmuch-hello
functionality.
Previously, this was calling into a notmuch-folder-count
function. Only, everything related to notmuch-folder is about to go
away, so lets have notmuch-hello define its own function
(notmuch-saved-search-count) for this purpose.
We use this function to abstract away the common 3-step process for
looking for a value for the saved-searches variable:
1. Look at the notmuch-saved-searches variable itself
2. Look at the notmuch-folders vaiable
3. Use a default value
We were already using this logic (open-coded) in notmuch-hello, but
notmuch.el was accessing notmuch-folders directly for the clever name
selection of search buffers.
I'm planning to rip out the notmuch-folder-mode completely. So as a
token kindness to existing users of notmuch-folders, I'm at least
making notmuch-hello support the notmuch-folders variable name as an
alternate for the new name of notmuch-saved-searches.
We've recently changed things so that the notmuch-hello screen is the
default view one gets by executing `notmuch'. So hide the "hello" name
from everything exposed in the customize interface, (leaving "hello"
as just an internal name within the implementation).
After the previous commit, toggling the visibility of tags could
result in notmuch-hello aborting with:
Wrong type argument: wholenump, -1
At least, the error only occurred for me when making tags visible. But
that may be because my longest tag name is longer than my longest
saved-search name.
After isearching for an entire saved-search name, the point will be
immediately after that name in the buffer. Before commit
c9ba61bebe the space right after the
name was part of the widget so the user could press RET right after
the isearch to activate the saved search.
The above commit broke that functionality. Restore it by including a
single space after each name as part of the widget.
And off by default. There's a notmuch-hello-show-tags option in
customize to toggle the default setting, as well as buttons to
persistently toggle the visibility for the current session.
I have enough tags in my database that it's quite a bit faster for
notmuch-hello to come up without showing the tags.
Previously, we preserved the current position only when returning to
the notmuch-hello buffer or when refreshing it. Fix to also preserve
the position when directly invoking notmuch-hello, (such as from a
global keybinding).
This give us a useful active widget by default, ("inbox"), and
otherwise gives the first saved search in the user's customized
list. Not having point on the search bar means that the various
keybindings are all available.
This command was previously written under the fragile assumption that
the search bar was always the third widget. That's no longer true with
the saved searches now appearing before the search bar, so we save the
position of the search bar and go directly to it now.
Once users start using saved searches regularly, it's expected that
these will become the primary access points to mail. So give them a
priority position in the buffer.
When we go into a search, and then later quit and return to the
notmuch-hello buffer, we want the point to remain in the same position
it was in when we left. So we have to call the position-remembering
notmuch-hello-update rather than notmuch-hello from the continuation.
Before refreshing, we check which widget we are currently on, (or look
for the next widget), and then we watch for that same widget to go by
when constructing the buffer contents. Finally, we jump to the
position we saw when the widget went by.
Previously, trailing spaces after each saved-search name were included
as part of the widget. This is going to be problematic for a future
change that will extract the widget's value and compare it to the
configured names of saved searches.
Instead, just include the name itself in the widget, and then insert
the spaces for separation afterwards.
The existing code inserts the signature before inserting the message
body (which it puts at the very end of the buffer - therefore AFTER
the signature). This little snippet makes us search backwards and
insert the message body before a signature, if it exists.
This also fixes a small indentation issue in David's code.

Previously this was just a message that was almost impossible for the
user to see. Now, the user gets to see the error message, and is
presented with a buffer that actually contains the Fcc header of
interest.
I have gone wild and added a defcustom "notmuch-fcc-dirs".
Depending on the value of that variable we will not do any
maildir fcc at all (nil, the default), or it is of the format
(("defaultsentbox")
("full name <email@address>" . "Work/sentbox")
("full name2 <email2@address2>" . "Work2/sentbox"))

The notmuch-hello functionality is now sufficiently useful that we
want to make it the default view of notmuch for new users. This also
effectively hides the "hello" name from the user, so we'll be free to
change that in the implementation if necessary.
This change also shuffles the requires between notmuch.el and
notmuch-hello.el. This fixes things so that our documented (require
'notmuch) is sufficient for getting the notmuch-hello functionality.
Finally, the shuffling caused the notmuch-search-oldest-first variable
from one file to the other. While doing that, give this variable the
defcustom treatment for easier customization.
When determining whether or not to re-align the head of the current
message with the top of the window, use `count-screen-lines' rather
than `count-lines' to allow for invisible text in the preceding
message. When comparing that number of lines against
`next-screen-context-lines', realign if the number of lines of the
previous message visible is 'smaller than or equal to' rather than
just 'smaller than' to improve usability.
For composing new messages and forwarding, leave the cursor on the
'To:' field. For replies, leave the cursor at the start of the

Set `buffer-invisibility-spec' to `nil' (a list) if it is just `t'
before inserting any body parts, otherwise removing items from
`buffer-invisibility-spec' (which is what
`notmuch-show-headers-visible' and `notmuch-show-message-visible' do)
is a no-op and has no effect. This caused threads with only matching
messages to have those messages hidden initially because
`buffer-invisibility-spec' stayed `t'.

The notmuch logo uses transparency. That can display poorly when
inserting the image into an emacs buffer (black logo on a black
background), so force the background colour of the image. We use a

`defface' can be used to declare the different possible colours, which
depend on whether the frame has a light or dark background.

- notmuch-wash-tidy-citations: Tidy up citations by:

Enable `notmuch-wash-tidy-citations' and
`notmuch-wash-compress-blanks' by default by adding them to
`notmuch-show-insert-text/plain-hook'. `notmuch-wash-wrap-long-lines'
is not enabled by default.
If `notmuch-wash-wrap-long-lines' is enabled, word wrapping of the
buffer leads to an unappealing display of text, so provide a function
to disable it and add it to the list of `notmuch-show-mode' hook
functions.
Add an `isearch-open-invisible' property to the overlays used to hide
citations and signatures, together with an appropriate function to
leave the invisible text visible should that be required.
This isn't ideal for me personally, since I usually want to inovke a
saved search rather than entering a new search textually. But it's at
least better than just putting point in the upper-left corner where it
doesn't do anything.
And similarly for notmuch-show-headers-visible to
notmuch-message-headers-visible.
I've never liked notmuch-show as a namespace prefix, but it looks
especially bad when it appears as "Notmuch Show Headers Visible" in
the customize buffer. Give nicer names to these variables which are
exported for user manipulation.
A tool `notmuch-addresses' is required to produce addresses which
match a query string. An example of a suitable script can be found in
the git repository at
http://jkr.acm.jhu.edu/git/notmuch_addresses.git
There are no doubt others.
The function was named and documented incorrectly before, saying that
it would "change the visibility of all messages". Instead it only
opens the messages that are closed---it doesn't simultanesously close
the messages that are open. (Granted, nobody would *want* that
behavior I don't think, but the naming was confusing before.)
`notmuch-show-toggle-all' changes the visibility all of the messages
in the current thread. By default it makes all of the messages
visible. With a prefix argument, it makes them all not visible.
Commit 44982ab332 added some extra
quoting when constructing a search. A previous version of this patch
had used single-quotation marks (') while this version used
double-quotation marks (").
The intent of the extra quoting was to allow notmuch-command to be set
to a script invoking ssh.
What actually happens, however is that the extra quotation marks make
it all the way into the query string seen by Xapian. And the double
quotes trigger phrase searching, (which isn't desired here). The
side-effect of that is that the emacs code would fallback to an
unqalified query and display all threads with all messages open.
We fix that side-effect now by using single-quote characters, but
we'll want a better fix in the future to avoid Xapian seeing these
characters at all I think.

This is the real commit for this functionality this time. The

Fix missing argumen in declaration of notmuch-search function and add

This is based on the prototype that Carl Worth described in the TODO
file. It provides a search bar as well as support for recent searches,
saved searches, and a list of all tags in the database (as well as the
number of messages with each tag).
The width of the authors field in search output was previously
specified in two places:
- `notmuch-search-authors-width': the limit beyond which the authors
names are truncated,
- `notmuch-search-result-format': the layout of the search results.
Changing the configuration of one of these may have required the user
to know about and adapt the other accordingly. This led to confusion.
Instead, remove `notmuch-search-authors-width' and perform truncation
based on the relevant field in `notmuch-search-result-format'.

With defcustom the user can easily find this variable (and its
documentation) within "M-x customize-group" "notmuch" (though finding
*that* is still tricky).
The new name of notmuch-poll-script is also easier to remember, (for
me at least).
Emacs scoping rules strongly encourage us to have fully-namespaced
function names. A prefix like "notmuch-search" is a pretty ugly
namespace name, but it's what we have for now.
The new functions first check if an external poll script has been defined in
the variable 'notmuch-external-refresh-script and if yes, runs that script
before executing the existing refresh function (which is bound to '=')
This can be used to have 'G' mimic the mutt behavior of polling an external
mail server - or if the mail polling is already automatic, it can trigger
the call to notmuch new and any necessary automatic tagging of new email.

Use the mailcap functionality to guess a MIME type for attachments of
type application/octet-stream and, presuming successful, feed the
attachment back into the display code with the determine type.
This is mostly useless at the moment, as the JSON output from notmuch
does not include the content of application/octet-stream parts, so
they cannot be displayed even if the guess is a good one.
If a text/plain part is not the first part in a message, add a label
in order that a user can see that multiple parts are present.
If a part has a 'filename' attribute, include it in any label
describing the part.
In the recent switch to a JSON-based emacs interface, RET now toggles
message visibility anywhere in the message, (rather than only on the
summary line). So we no longer need this separate "b" binding for this.
Additionally, the body toggle was implemented independently from RET,
so after hiding a message with "b" one could not make it visible with
RET. This confusing state is now no longer possible, (since the
:body-visible property is removed entirely).
This reverts commit fbec989fe3.
I only pushed this accidentally. See message
id:871ver6u9r.fsf@yoom.home.cworth.org for the various reasons I
didn't like this patch, (mostly I think the association of 'F' is
wrong).
With the recent addition of "*" being a special case for a search
matching all messages, we have to take care when doing a filter
operation. In this case it's not legal to simply append and get:
* and <some-new-search-terms>
Instead we carefully construct a new search string of only:
<some-new-search-terms>
This could all be avoided if we had a parser that could understand
"*" with the meaning we want.
Clean up code duplication, as per Carl's suggestion, by making
notmuch-search-{add/remove}-tag-thread a special case of the -region
commands, where the region in question is between (point) and (point).
There was a bug in notmuch-search-{add,remove}-tag-region, which would
not behave correctly if the region went beyond the last message. Now,
instead of simply iterating to the last line of the region, these
functions will iterate to the minimum of the last line of the region
and the last possible line, i.e.
(- (line-number-at-pos (point-max)) 2)
Tested-by: Carl Worth <cworth@cworth.org> Note that the old, buggy
behavior included infinite loops of emacs lisp code, so the new
behavior is significantly better than that.
Put single-quotes around the argument of the `show --entire-thread' command
in notmuch-show. This change should have no effect on normal usage.
However, it allows us to use the notmuch.el client with a remote notmuch
binary and database over ssh (by, e.g., setting `notmuch-command' to a
simple shell script). Without the quotes, ssh will not send the command
properly.
One very simple example script is as follows. (Note that it requires
keypair login to the ssh server.)
#!/bin/sh
SSH_BIN="/path/to/local/ssh"
NOTMUCH_HOST="my.remote.server"
NOTMUCH_REMOTE_PATH="/path/to/remote/notmuch"
$SSH_BIN $NOTMUCH_HOST $NOTMUCH_REMOTE_PATH $@
These commands act on all messages in the thread, not simply those
that match the search. (There are use case for both behaviors, but the
documentation must match the behavior that's actually implemented).
This patch adds `-region' versions of the `notmuch-search-' commands to find
properties. It also splits up `notmuch-add/remove-tags' into both a
`-thread' and a `-region' version. (This makes us modify
`notmuch-search-archive-thread' to use the
`notmuch-search-remove-tag-thread' function, instead of
`notmuch-search-remove-tag', for consistency.) The add/remove-tag command
called by pressing `+' or `-' will then choose accordingly, based on whether
region is active.
This version fixes a couple of errors in the first version, which led to
incorrect marking of some tags in the search view (though the actual
tagging was still correct). It's also based on current master.
I'm not sure any more if region selection is actually the correct way to
do this, or if a mutt-style message-marking method would be better. But
I didn't want a buggy incorrect version out there.
As put forth in the commit that enabled this functionality, the last
few lines of a citation are often much more important. In that case,

Arbitrary font faces can be specified for given thread tags. By

Instead, simply byte-compile the emacs source files as part of "make"
and install them as part of "make install". The byte compilation is
made conditional on the configure script finding the emacs binary.
That way, "make; make install" will still work for someone that doesn't
have emacs installed, (which was the only reason we had made a separate
"make install-emacs" target in the first place).
With the original quiet function, there's an actual purpose (hiding
excessively long compiler command lines so that warnings and errors
from the compiler can be seen).
But with things like quiet_symlink there's nothing quieter. In fact
"SYMLINK" is longer than "ln -sf". So all this is doing is hiding the
actual command from the user for no real benefit.
The only actual reason we implemented the quiet_* functions was to be
able to neatly right-align the command name and left-align the arguments.
Let's give up on that, and just left-align everything, simplifying the
Makefiles considerably. Now, the only instances of a captialized command
name in the output is if there's some actually shortening of the command
itself.
Initially this file provides one main function
notmuch-query-get-threads, which takes a set of search terms, and

A set of notmuch-query-map-* functions are provided to help map

The function notmuch-query-get-message-ids uses this machinery to get
the set of message-ids matching a query.

We currently allow the cursor to be positioned on the "End of search
results" line after the last thread in a search buffer. When
refreshing on this line, there's no thread ID to be used as the
target.
Previously, a refresh from this case would result in a nil thread
target, but we were also using nil to indicate that the target thread
had been found. This caused the position to be lost during refresh,
(the cursor would move from the last line in the buffer to the first).
We fix this by using a magic string of "found" rather than nil to
clearly indicate whether the target thread has actually been found.
It doesn't make sense to move the cursor to some random point in the
middle of a line. We always want the refresh to leave the cursor at
the beginning of some line instead.
We were previously maintaining two lists of the child Makefile
fragments---one for the includes and another for the dependencies. So,
of course, they drifted and the dependency list wasn't up to date.
We fix this by adding a single subdirs variable, and then using GNU
Makefile substitution to generate both the include and the dependency
lists.
Some side effect of this change caused the '=' assignment of the dir
variable to not work anymore. I'm not sure why that is, but using ':='
