This is a workaround for a freeze when suspending Helix with C-z on
non-Windows systems. The check for the keyboard enhancement protocol
locks up crossterm's internal event reading/polling system by trying to
set up multiple concurrent readers. `input_stream.next()` sets up one
reader looking for regular crossterm events while the
`supports_keyboard_enhancement` query sets up another looking for
internal events. The latter hangs for two seconds or until the former
yields an event. By handling signals first we don't lock up the mutex
by trying to read keyboard events.
Since crossterm 0.26.x, we receive press/release keyboard events on
Windows always. We can ignore the release events though to emulate
the behavior of keyboard input on Windows on crossterm 0.25.x.
When the Kitty Keyboard Protocol is enabled, S-backspace is
distinguished from backspace with no modifiers. This is awkward when
typing because it's very easy to accidentally hold shift and press
backspace temporarily when typing capital letters.
Kakoune (which is also a Kitty Keyboard Protocol application) treats
S-backspace as backspace too:

Check if the stack frames contain the thread id and the frame before
trying to get the frame id. If case any of the two fails to be
found, provide the user with messages to inform them of the issue and
gracefully return.

Send a `Disconnect` DAP request if the `Terminated` event is received.
According to the specification, if the debugging session was started by
as `launch`, the debuggee should be terminated alongside the session. If
instead the session was started as `attach`, it should not be disposed of.
This default behaviour can be overriden if the `supportTerminateDebuggee`
capability is supported by the adapter, through the `Disconnect` request
`terminateDebuggee` argument, as described in
[the specification][discon-spec].
This also implies saving the starting command for a debug sessions, in
order to decide which behaviour should be used, as well as validating the
capabilities of the adapter, in order to decide what the disconnect should
do.
An additional change made is handling of the `Exited` event, showing a
message if the exit code is different than `0`, for the user to be aware
off the termination failure.

The completion component has a separate branch for handling the
Escape key but it can use the `ignore_escape_key` helper added for
signature-help instead.
This should not cause a behavior change - it's just cleaning up the
completion component.
* feat(ui): deprecated completions
Mark deprecated completions using strike-through
(CROSSED_OUT modifier). The deprection information
is taken either from the `deprecated` field of the
completion item or from the completion tags.
The field seems to be the older way of passing
the deprecated information and it was already
marked as deprecated for Symbol. In completion
item the field is still valid but it seems that
the LSP is moving in the general direction of using
tags for this kind of information and as such
relying on tags as well seems reasonable and
future-proof.
So far LSP always required that `PositionEncoding.characters` is an
UTF-16 offset. Now that LSP 3.17 is available in `lsp-types` request
the server to send char offsets (UTF-32) or byte offsets (UTF-8)
instead. For compatability with old servers, UTF-16 remains as the
fallback as required by the standard.
* Make `m` textobject look for pairs enclosing selections
Right now, this textobject only looks for pairs that surround the
cursor. This ensures that the pair found encloses each selection, which
is likely to be intuitively what is expected of this textobject.
* Simplification of match code

* Adjust logic for ensuring surround range encloses selection
Prior, it was missing the case where the start of the selection came
before the opening brace. We also had an off-by-one error where if the
end of the selection was on the closing brace it would not work.
* Refactor to search for the open pair specifically to avoid edge cases
* Adjust wording of autoinfo to reflect new functionality
* Implement tests for surround functionality in new integration style
* Fix handling of skip values
* Fix out of bounds error
* Add `ma` version of tests
* Fix formatting of tests
* Reduce indentation levels for readability, and update comments
* Preserve each selection's direction with enclosing pair surround
* Add test case for multiple cursors resulting in overlap

Select line 2 with x, then type Alt-C; Helix will go into an infinite
loop. The saturating_sub keeps the head_row and anchor_row pinned at 0,
and a selection is never made since the first line is too short.
`:write` and other file-saving commands now check the file modification
time before writing to protect against overwriting external changes.

This matches the behavior from 42ad1a9e04
but for the first and last change. The selection rules are the same
as for goto_next/prev_change: additions and modifications select the
added and modified range while deletions are represented with a point.
This will allow testing more of the code base, as well as enable UI-
specific testing.
Debug mode builds are prohibitively slow for the tests, mostly
because of the concurrency write tests. So there is now a profile for
integration tests that sets the optimization level to 2 for a few helix
crates, and lowers the number of rounds of concurrent writes to 1000.

This change makes `ms<ret>` work similarly to `t<ret>` and related
find commands: when the next event is a keypress of Enter, surround
the selection with the document's line-endings.
* rework positioning/rendering, enables softwrap/virtual text
This commit is a large rework of the core text positioning and
rendering code in helix to remove the assumption that on-screen
columns/lines correspond to text columns/lines.
A generic `DocFormatter` is introduced that positions graphemes on
and is used both for rendering and for movements/scrolling.
Both virtual text support (inline, grapheme overlay and multi-line)
and a capable softwrap implementation is included.

The new version of the `toml` crate is based on `toml_edit` and does
not support zero copy deserialization anymore. So we need to deserialize
`String` instead of `&str` in the keympa
increment/decrement (C-a/C-x) had some buggy behavior where selections
could be offset incorrectly or the editor could panic with some edits
that changed the number of characters in a number or date. These stemmed
from the automatic jumping behavior which attempted to find the next
date or integer to increment. The jumping behavior also complicated the
code quite a bit and made the behavior somewhat difficult to predict
when using many cursors.
This change removes the automatic jumping behavior and only increments
or decrements when the full text in a range of a selection is a number
or date. This simplifies the code and fixes the panics and buggy
behaviors from changing the number of characters.
After changes in #5239, the loaded configuration wasn't stored,
resulting in a success message even if the instance kept the previous
configuration values.
Commit 1b89d3e535 introduced a regression
where opening a new file would no longer work, because attempting to
canonicalize its path would lead to a "No such file or directory"
error. Fall back to opening a new file when encountering an error to
fix this case.
This commit addresses issue 5193, where the author
requested that the name of the binary needed is printed along
with the rest of the health information.
This commit adds a format! macro which formats in the name of the
binary and then it will be printed along with the rest of the
debug information. The value in cmd is referenced to the call
to which, and then consumed upon the call to format!
This roughly matches the behavior of the diagnostic picker: when
jumping to a diagnostic with `[d`/`]d`/`[D`/`]D`, the range of the
diagnostic is selected instead of the start point.
A language server might send None as the response to workspace symbols.
We should treat this as the empty Vec rather than the server sending
an error status. This fixes the interaction with gopls which uses
None to mean no matching symbols.
If the new results shown by the picker select a file that hasn't been
previewed before, the idle timeout would not trigger highlighting on
that file. With this change, we reset the idle timeout and allow that
file to be highlighted on the next idle timeout event.
This change uses the idle-timeout event to trigger fetching new results
in the DynamicPicker, so idle-timeout becomes a sort of debounce. This
prevents querying the language server overly aggressively.
Most language servers limit the number of workspace symbols that
are returned with an empty query even though all symbols are
supposed to be returned, according to the spec (for perfomance
reasons). This patch adds a workspace symbol picker based on a
dynamic picker that allows re-requesting the symbols on every
keypress (i.e. when the picker query text changes). The old behavior
has been completely replaced, and I have only tested with
rust-analyzer so far.
