Without this little patch notmuch fails if asked to display a saved
search that has zero results
Edited-by: David Edmondson <dme@dme.org>: With code that is a little
more "emacsy".
Remove them from non-top-level entry points, (such as the functions to
set notmuch modes and the deprecated notmuch-folder function). And add
one to the notmuch-hello function. Also, add missing documentation
string to notmuch-hello.
The GNU Emacs Lisp Reference Manual section D.1 says:

Follow this advice, requiring the following changes where `cl' was
used at runtime:
- replace `rassoc-if' in `notmuch-search-buffer-title' with the `loop'
macro and inline code. At the same time find the longest prefix
which matches the query rather than simply the last,
- replace `union', `intersection' and `set-difference' in
`notmuch-show-add-tag' and `notmuch-show-remove-tag' with local code
to calculate the result of adding and removing a list of tags from
another list of tags.
Insert a separator every three digits when outputting numbers. Allow
the user to choose the separator by customizing
`notmuch-decimal-separator'. Widen the space allocated for message
counts accordingly.
This lets us pick up later changes to widget-keymap if the user
customizes it in some way. This is the recommended way to use
`widget-keymap', according to its help.
This enables the nifty '?' key binding to work in notmuch-hello
(although for some strange reasons I don't see any descriptions for
specific key bindings yet. Not sure how that is supposed to work
though.
But this starts, runs and behaves identical to the existing code.

Add `notmuch-column-control', which has three potential sets of
values:
- t: automatically calculate the number of columns per line based on
the tags to be shown and the window width,
- an integer: a lower bound on the number of characters that will be
used to display each column,
- a float: a fraction of the window width that is the lower bound on
the number of characters that should be used for each column.
So:
- if you would like two columns of tags, set this to 0.5.
- if you would like a single column of tags, set this to 1.0.
- if you would like tags to be 30 characters wide, set this to
30.
- if you don't want to worry about all of this nonsense, leave
this set to `t'.
- If no saved searches exist or are displayed, don't signal an error,
- If no saved searches exist or are displayed, leave the cursor in the
search bar,
- Minor layout improvements.
The fix in 1e18711543 broke end-of-row
wrapping when drawing the table of tags/saved searches. Fix that and
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.
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 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.
Avoiding adding the same search string to the 'recent searches' list
more than once by testing whether the string was already used with
`member' rather than `memq'.
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
face (`notmuch-hello-logo-background') to represent the colour so that
`defface' can be used to declare the different possible colours, which
depend on whether the frame has a light or dark background.
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.
Define a new `mail-user-agent' (`notmuch-user-agent') and use it by
default. Re-arrange various routines that send mail to use this
(compose, reply, forward). Insert a `User-Agent:' header by default.
This is the real commit for this functionality this time. The
previous attempt to merge this code:
commit 57926bc7b0
was botched (by Carl Worth, not David) to include only the Makefile
change. So the build was broken until this commit that actually adds
the new file.
Fix missing argumen in declaration of notmuch-search function and add
a definition of notmuch-search-continuation to avoid warning about
assignment to a free variable.
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).
