The following functionalities are added to configure aerc ui styles.
- Read stylesets from file with very basic fnmatch wildcard matching
- Add default styleset
- Support different stylesets as part of UiConfig allowing contextual
styles.
- Move widgets/ui elements to use the stylesets.
- Add configuration manual for the styleset
This adds the commands pin-tab and unpin-tab. Once pinned a tab lives on
the left of the tabstrip and has a configurable marker, defaulting to `
before its name.
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.
A popover is a special UI element which can be layered over the rest of
the UI (i.e. it is painted last) and can fall anywhere on the screen,
not just with the bounds of its parent's viewport/context. With these
special abilities comes the restriction that only one popover may be
visible on screen at once.
Popovers are requested from the UI context passed to Draw calls and
specify the anchor point and the desired dimensions. The popover is then
fit to the available space and placed relative to the anchor point.
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.
Previously removing a tab would always pop from the history of tabs.
This checks to see if the closing tab is the one selected, if it is then
we use the history, otherwise we only need to change the selected tab if
it was after (to the right of) the closing tab, in which case we just
decrement the selected index.
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].
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.
Tabstrip didn't take into account the width of the context. Now, it just
shows as many tabs as can fit and truncates the last one if necessary.
In future it probably would be best to ensure that the selected tab is
rendered on the screen.
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.
Executing :close on a terminal would panic due to it already having been
removed.
This is also related to the fact that removing a tab doesn't check for
whether it actually found a tab to remove or not.
The grid was not checking there was enough space for the cells so would
just attempt to create subcontexts that don't actually fit.
This attempts to use the remaining space and then if there is no space
then it just skips drawing this cell.
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 -
If the column weights do not collectively divide the extent of the grid
layout then some width was not used and so would not be redrawn,
resulting in previous drawings showing through.
This fixes this by checking if there is any remainingExact width and if
there is it is assigned to the weighted columns by their proportion from
left to right.
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 makes it so an atomic `invalid` value is used instead of an unbuffered
channel. When many invalidations kick in, a lot of values were sent to the
channel.
(Since OnInvalidate's callback can be run in any goroutine, we need to be
careful about races here.)
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.
