d7d0d5ffb7 resolves completion items on
the idle-timeout event. The `Completion::resolve_completion_item`
function blocks on the LSP request though, which blocks the compositor
and in turn blocks the event loop. So until the language server returns
the resolved completion item, Helix is unable to respond to keypresses
or other LSP messages.
This is typically ok since the resolution request is fast but for some
language servers this can be problematic, and ideally we shouldn't be
blocking like this anyways.
When receiving a `completionItem/resolve` request, the Volar server
sends a `workspace/configuration` request to Helix and blocks itself
on the response, leading to a deadlock. Eventually the resolve request
times out within Helix but Helix is locked up and unresponsive in that
window.
This change resolves the completion item without blocking the
compositor.
* init
* cargo fmt
* optimisation of the scrollbar render both for Menu and Popup. Toggling off scrollbar for Popup<Menu>, since Menu has its own
* rendering scroll track
* removed unnecessary cast
* improve memory allocation
* small correction
Some language servers may not send the `documentation` field if it
is expensive to compute. Clients can request the missing field with
a completionItem/resolve request.
In this change we use the idle-timeout event to ensure that the current
completion item is resolved.
Ported over from 61365dfbf3 in the `gui` branch. This will allow
adding our own events, most notably an idle timer event (useful
for adding debounced input in [dynamic pickers][1] used by interactive
global search and workspace symbols).

* Refactor menu::Item to accomodate external state
Will be useful for storing editor state when reused by pickers.
* Add some type aliases for readability
* Reuse menu::Item trait in picker
This opens the way for merging the menu and picker code in the
future, since a picker is essentially a menu + prompt. More
excitingly, this change will also allow aligning items in the
picker, which would be useful (for example) in the command palette
for aligning the descriptions to the left and the keybinds to
the right in two separate columns.
The item formatting of each picker has been kept as is, even though
there is room for improvement now that we can format the data into
columns, since that is better tackled in a separate PR.
* Rename menu::Item::EditorData to Data
* Call and inline filter_text() in sort_text() completion
* Rename diagnostic picker's Item::Data
* Add single width left margin for completion popup
* Clear with ui.menu style before rendering menu
When rendering a completion popup, the popup component will clear
the area with ui.popup and then the menu component would draw over
it using a table component. We remove the left edge of the area
before passing it to the table component (so that it will be left
as padding), and the table component uses ui.menu as the style.
If ui.menu and ui.popup are different the left edge of the popup
will look different from the rest of the popup. We avoid this by
clearing the whole area with ui.menu in Menu::render
The scrollbar length used to increase with more entries in the menu,
which was counter-intuitive to how scrollbars worked in most
applications. Turns out there was a typo in the floor division
implementation :)
* ignore Enter keypress when menu has no selection
supersedes #1622
Builds on the work in #1285. I want to allow Enter to create a newline
when there is no selection in the autocomplete menu.
This occurs somewhat often when using LSP autocomplete in Elixir which
uses `do/end` blocks (and I set the autocomplete menu delay to 0 which
exacerbates the problem):
```elixir
defmodule MyModule do
def do_foo(x) do
x
end
def other_function(y) do|
end
```
Here the cursor is `|` in insert mode. The LSP suggests `do_foo` but I
want to create a newline. Hitting Enter currently closes the menu,
so I end up having to hit Enter twice when the module contains any
local with a `do` prefix, which can be inconsistent. With this change,
we ignore the Enter keypress to end up creating the newline in this case.
* pop compositor layer when ignoring Enter keypress
* move closing function out of consumed event result closure
* explicitly label close_fn as an 'Option<Callback>'
* Add Event::Used to use event callback without consuming
* Close popup if contents ignored event
* collect event results before executing callbacks
* don't add new result variant, use Ignored(..) instead
* break in match cases
* Make auto_close configurable
* fix merge
* auto close hover popups
* fix formatting
* Macros WIP
`helix_term::compositor::Callback` changed to take a `&mut Context` as
a parameter for use by `play_macro`
* Default to `@` register for macros
* Import `KeyEvent`
* Special-case shift-tab -> backtab in `KeyEvent` conversion
* Move key recording to the compositor
* Add comment
* Add persistent display of macro recording status
When macro recording is active, the pending keys display will be shifted
3 characters left, and the register being recorded to will be displayed
between brackets — e.g., `[@]` — right of the pending keys display.
* Fix/add documentation
Adds ctrl! and alt! macros (which existed before the big keymap
refactor) and uses them in event handling of Components. Note
that this converts crossterm's KeyEvent to our own KeyEvent on
each invocation of handle_event in Components.
* Refactor new Rect construction
Introduces methods that can be chained to construct new Rects
out of pre-existing ones
* Clamp x and y to edges in Rect chop methods
* Rename Rect clipping functions
* Add preview pane for fuzzy finder
* Fix picker preview lag by caching
* Add picker preview for document symbols
* Cache picker preview per document instead of view
* Use line instead of range for preview doc
* Add picker preview for buffer picker
* Fix render bug and refactor picker
* Refactor picker preview rendering
* Split picker and preview and compose
The current selected item is cloned on every event, which is
undesirable
* Refactor out clones in previewed picker
* Retrieve doc from editor if possible in filepicker
* Disable syntax highlight for picker preview
Files already loaded in memory have syntax highlighting enabled
* Ignore directory symlinks in file picker
* Cleanup unnecessary pubs and derives
* Remove unnecessary highlight from file picker
* Reorganize buffer rendering
* Use normal picker for code actions
* Remove unnecessary generics and trait impls
* Remove prepare_for_render and make render mutable
* Skip picker preview if screen small, less padding
* reverse the dependency between helix-tui and helix-view by moving a fiew types to view
* fix tests
* clippy and format fixes
