There are several ways the ui message channel can fill up leading to
deadlocks.
1) Invalidate() changes the value of uiState to DIRTY. The following
call sequence:
QueueRedraw()
Invalidate()
QueueRedraw()
Leads to multiple nil messages being queued in the message channel
whereas one could assume that the second QueueRedraw() would do
nothing. This is caused by the tri-state nature of uiState.
2) We use the same channel to convey state change, keyboard events and
redraw requests. Since a keyboard event almost always triggers
a redraw, we end up trying to append a redraw message in the same
goroutine that reads from the channel. This triggers a deadlock when
there are more than 50 pending messages.
Solve the issue by using multiple channels, one per type of message that
needs to be sent to the main ui thread.
Remove QueueRedraw() and merge its functionality in Invalidate(). Only
use a DIRTY/CLEAN state to determine if something needs to be queued in
the redraw channel.
Use a channel for quitting instead of an atomic. Restructure some code
functions to have a cleaner API.
Use a for loop in the main thread and select from all channels.

Fix cursor index after stemming and reset it to the position where the
completion should occur. Only stem to add more information and not
remove any user input.
Stemming is activated on the textinput line when the user presses the
Tab key. The idea of stemming is to adjust the textinput line to the
common ground (="the stem") of the completions options.
When the stemmed input line is set, however, the cursor will be moved to
the end of the line if there is a text part on the right side of the
cursor where the completion should occur. Another Tab press will
activate the onStem function again, which then removes the right part of
the text input leading to the loss of the user input.
This can be prevented by moving the cursor to the place of the
completion after stemming.

Pressing up while in command mode, calls TextInput.Set() with the
previous command in the history. If the command exceeds the current
terminal width, there is a scroll mechanism that puts the cursor at the
end of the text (see ensureScroll()). However, the offset used to
perform the draw is not the current scroll value but the "previous" one.
When the one before last command required a longer scroll offset than
the current command length, this causes a crash:
Error: runtime error: slice bounds out of range [348:5]

There are actually two distinct issues here:
1) The scroll offset used for drawing must be the current one, not the
one from the previous ensureScoll() call.
2) The scroll offset must be reset when changing the text with
TextInput.Set(). Other methods that change the text actually call
ensureScroll but they make incremental changes to the text, since Set
completely overwrites everything, it makes more sense to set the
scroll offset to 0.

The QueueRedraw function should always be preceeded by a call to
ui.Invalidate in order to make a redraw a occur. In one instance, this
was not done and it was possible for the UI to not redraw itself (when a
terminal closes, a UI redraw request is made but it is possible for the
UI to not be invalidated as a result of the close).
Move the call to Invalidate into the QueueRedraw function to ensure that
every QueueRedraw call will redraw the screen.

When doing address completion via commands that take a while to run,
having the completion trigger even with a single character can be
non-optimal. Add an option to allow requiring a minimum number of
characters to actually run the completion command.

Commit 27425c15c4b9 ("autocompletion: fix slice out of bounds access")
introduced a regression in the autocompletion that messes up the order
of last entered chars when autocompletion runs.
The ranges for a slice a[low:high] are 0 <= low <= high <= len(a) [0]
To reproduce with the ":cf" command:
1) enter ":c"
2) wait for autocompleteion
3) enter "f"
4) the prompt will now be ":fc"

Add check for public keys of all message recipients (to, cc, and bcc)
before sending the message. Adds an OnFocusLost callback to header
editors to facilitate a callback for checking keys whenever a new
recipient is added (OnChange results in too many keyring checks).
Once encryption is initially set, the callbacks are registered. If a
public key is not available for any recipient, encryption is turned off.
However, notably, the callbacks are still registered meaning as s soon
as the user removes the recipients with missing keys, encryption is
turned back on.

as per the discussion https://lists.sr.ht/~sircmpwn/aerc/patches/15367
this handles completions in `completer/completer.go` by enabling the
completer to return a `prefix` that will be prepended to the selected
completion candidate.

Also update to the tcell v2 PaletteColor api, which should keep the chosen
theme of the user intact.
Note, that if $TRUECOLOR is defined and a truecolor given, aerc will now stop
clipping the value to one of the theme colors.
Generally this is desired behaviour though.

- Read stylesets from file with very basic fnmatch wildcard matching
- Add default styleset
- Support different stylesets as part of UiConfig allowing contextual

- Move widgets/ui elements to use the stylesets.
- Add configuration manual for the styleset

Before, pressing <Enter> when completions were visible would execute the
selected completion. As soon as completions were provided, the first
item would be selected. This could cause issues e.g. when changing
folders:
:cf <Enter>
Previously, this would have selected the first folder in the list. Now,
since <Tab>, <C-n>, etc have not been pressed to select the first
completion, the command above simply executes `:cf `.
To accomplish this, a "no-op completion" has been added at index -1.
|
| |
|
|
|
|
| |
Rather than showing completions inline in the text input, show them in a
popover which can be scrolled by repeatedly pressing the tab key. The
selected completion can be executed by pressing enter.

Adds a message indicating the user's ability to :save or :pipe a message
with an unsupported mimetype and also adds a selector widget (similar to
the tutorial).
The selector widget was previously defined in the account wizard module,
so this commit breaks it out into its own module to allow for re-use.
Further, modify the BeginExLine() function to take an argument that
pre-populates the command line, allowing functions to initiate an ex
command without executing it.
Closes #95.

This adds the Mouseable interface. When this is implemented for a
component that item can accept and process mouseevents.
At the top level when a mouse event is received it is passed to the
grid's handler and then it trickles down until it reaches a component
that can actually handle it, such as the tablist, dirlist or msglist.
A mouse event is passed so that components can handle other things such
as scrolling with the mousewheel. The components themselves then perform
the necessary actions.
Clicking emails in the messagelist opens them in a new tab.
Textinputs can be clicked to position the cursor inside them.
Mouseevents are not forwarded to the terminal at the moment.
Elements which do not handle mouse events are not required to implement
the Mouseable interface.

Choose the readline defaults for the behavior of these two
functions/keybindings. Depending on the program, either of these can
delete the whole line.
Note that by default in [compose], <C-k> is bound to :prev-field<Enter>.
Leave it up to the user whether or not they want to rebind the key in
[compose].

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.
