Fixes ~sircmpwn/aerc2#205. Many functions do a nil check on the store,
so this changes Store() so it returns nil when msglist is nil.
It also places the Scroll() behind the nil check in the next-message command.

We need some way to signal the backends that we are about to shutdown,
allowing them to clean up (for example in notmuch committing the db changes).
This commit implements a hook which gets called upon shutdown, providing
backends implement the io.Closer interface.
Before, the text/plain part of the multipart MIME message was not being
correctly terminated with its boundary. The multipart writer writes the
terminator when its Close is called, but since the call to Close() was
deferred, it was not being called until after the attachments were being
written resulting in the boundary not being included at all.
Make the msglist aware of whether we are still initializing or not.
We never stopped spinning the msglist if we didn't get any Directories back
from types.ListDirectories.
With this change, we can set the init state from the account and display
the spinner only if we don't know whether we have directories or not and else
the "no messages" string from the config.
Add a "new-message-bell" option to the UI section of aerc.conf. A new
hook into the message store allows the msglist widget to detect new
messages being added to the displayed list. When new messages are
delivered, and the new-message-bell option is enabled (as it is by
default), the terminal will beep.
This allows selection of a tab using its index. It attempts to parse the
given argument as a number, if it fails then it uses it as a name.
Also supports relative indexes using prefixed + or -.
Add a command for removing attachments from a composed message. Syntax
is :detach [path], with path being an optional argument specifying the
path of one existing attachment. If no path is specified, the first
attachment is removed.
Adding an attachment, switching to a different tab, and switching back
to the review message caused the "filled space" in the review message to
disappear, since there was one too many rows in the layout.
This adds tab completion to textinput components. They can be configured
with a completion function. This function is called when the user
presses <tab>. The first completion is initially shown to the user
inserted into the text. Repeated presses of <tab> or <backtab> cycle
through the completions list. The completions list is invalidated when
any other non-tab-like key is pressed.
Also changed is some logic for current completion generation so that
all available commands are returned when <tab> is pressed with no
current text and similarly for arguments of commands.
Aerc will keep track of the previous 1000 commands, which the user can
cycle through using the arrow keys while in the ex-line. Pressing up
will move backwards in history while pressing down will move forward.
This map represents a mapping from directory names to their associated
messagestores anyway so they should be under dirstore. This simply moves
them there and adds some methods required to interact with them.
This patch sets up the trigger config section of aerc.conf.
Each trigger has its own function which is called from the place where
it is triggered. Currently only the new-email trigger is implemented.
The triggers make use of format strings. For instance, in the new-email
trigger this allows the user to select the trigger command and also the
information extracted from the command and placed into their command.
To actually execute the trigger commands the keypresses are simulated.
Further triggers can be implemented in the future.
Formatting of the command is moved to a new package.
This command allows the user to change tab by giving the tab name. This
can be tab completed too. The previous tab is stored in the tabs module
so that when a new tab is created it is still possible to go to the
previous one.
Normal invocation is :ct folder
Previous tab is :ct -
Allow users to add attachments to emails in the Compose view. Syntax is
:attach <path>, where path is a valid file. Attachments will show up in
the pre-send review screen.
A user may want to be able to see what mimetype they are viewing, so
that they can determine what program it may be opened in or for some
other reason.
The config option is under the [viewer] section and is called
'always-show-mime'. It defaults to false to preserve the current
behaviour.
This patch adds the currently pressed keys to the statusline. This is
useful when keybindings are multiple keys long and you might forget
which keys are already pressed.
This introduces a new interface `Clickable`. I'd imagine this would be
implemented for most widgets eventually and would allow for programs run
in the terminal to also have their mouse events forwarded to them.
For the tabs it was relatively simple to check that the position of the
click is within the boxes for the tabs. For other components I'd imagine
that some state representing their currently drawn bounding box would be
useful.
This allows users to use backtab (Shift+tab) to go back through the
fields in the tutorial, like C-K. This then mimics the other methods in
having a forward and backward variant.
Also documented this in the wizard help paragraph.
Before, we were using several IMAP-specific concepts to represent
information being displayed in the UI. Factor these structures out of
the IMAP package to make it easier for other backends to provide the
required information.
Before, the information needed to display different parts of the UI was
tightly coupled to the specific messages being sent back and forth to
the backend worker. Separating out a models package allows us to be more
specific about exactly what a backend is able to and required to
provide for the UI.
Assuming we always have a sorted dirlist
(other code depends on that already), we don't need to loop over the
dirStore.
Any filtering done should be performed elsewhere
Because editors like vim use backupfiles and rename them to the original
name, the file handle used can point to the wrong file. Reopening the
file should fix this.
Many email providers use the imap sub-domain for imap and the smtp
sub-domain for smtp. FastMail is an example of this[1]. This is a small
quality-of-life improvement which automatically replaces imap.* with
smtp.* when going from the imap screen to the smtp screen in the wizard
[1]: https://www.fastmail.com/help/technical/servernamesandports.html
This implements selecting the most preferred mimetype under the
'View->Alternatives' configuration setting when viewing a message.
Mimetypes in the alternatives array are weighted by their position,
where the lower the index in the array the higher the priority, so this
is taken into account during selection.
If no message part matches a mimetype in the alternatives array, then it
selects the first mimetype in the message.
Adds an archive command that moves the current message into the folder
specified in the account config entry.
Supports three layouts at this point:
- flat: puts all messages next to each other
- year: creates a folder per year
- month: same as above, plus folders per month
This also adds a "-p" argument to "cp" and "mv" that works like
"--parents" on mkdir(1). We use this to auto-create the directories
for the archive layout.
Consists of 3 functions
* Store: Access to MessageStore type
* SelectedAccount: Access to Account widget that the target widget
belongs to
* SelectedMessage: Current message (selected in msglist or the one we
are viewing)

* :save takes a path and saves the current message part to that location
* :pipe is the same as pipe on the account page, but uses the current
message part rather than the whole email (ie :pipe gzip -d)
* Refactored account:pipe and extracted common pipe code to
commands.util.QuickTerm
* Added helper command aerc.PushError
This commit introduces a new Aerc.Tick function that should be called to
refresh the internal state. This in turn makes each AccountView process worker
events.
The UI goroutine repeatedly refreshes the internal state before drawing a new
frame. The reason for this is that many worker messages may need to be
processed for a single frame, and drawing the UI is far slower than refreshing
the internal state. This has been confirmed in my testing (calling Aerc.Tick
only once per frame results in a slower display).
Many synchronization code has been removed. We can now write widgets without
having to care so much about races. The remaining sync users are:
- widgets/spinner: the spinner value is updated from inside an internal
goroutine
- lib/ui/invalidatable: Invalidate may be called from any goroutine
- lib/ui/grid: same
- lib/ui/ui: an internal goroutine needs read access to UI.exit
- worker/types/worker: Worker.callbacks is used for both worker and UI
callbacks
The exact goroutine requirements for Drawable have been documented.
MessageStore has a lot of exported fields that can be read from the outside.
Each read must be protected, because a call from Update could happen at any
time.
Many Drawable implementations have their own Invalidate and OnInvalidate
functions, with an unexported onInvalidate field. However OnInvalidate and
Invalidate are usually not called in the same goroutine. This results in a race
on this field, e.g.:

To fix this, introduce a new type, Invalidatable, which protects the field.
Unfortunately the Drawable must be passed to the callback function in
Invalidate, so we still need to re-implement this in each Invalidatable user.
It's accessed by the goroutine which increments it and the goroutine that draws
the widget at the same time. Use atomic instead.

When changing to an empty directory, ml.selected is 0, and the length
of ml.store.Uids is 0. The loop condition is always true so we have
an infinite loop causing 100% CPU usage and prevents us to change to
other directories.

This is a simple mostly straight forward switch to tcell in favor of
termbox.
It uses the tcell native api (not the compat layer) but does not make
use of most features.
Further changes should include moving to tcell's views.TextArea and the
general built in widget behaviour instead of the current ad hoc
implementation.
