Previously, commands such as `r<tab>` (replace with tab) or `t<tab>`
(select till tab) had no effect. This is because `KeyCode::Tab` needs
special treatment (like `KeyCode::Enter`).
This change handles a language server exiting. This was a UX sore-spot:
if a language server crashed, Helix did not recognize the exit and
continued to send requests to it. All requests would timeout since they
would not receive responses. This would also hold-up Helix closing
itself down since it would try to gracefully shutdown the server which
is implemented in the LSP spec as a request.
We could attempt to automatically restart the language server on crash.
I left this for future work since that change will need to be slightly
complicated: it will need to cover the case of a language server
repeatedly crashing.
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.
PR #4134 switched the autocomplete menu from alphabetical to fuzzy
sorting. This commit removes the still existing filtering by prefix and
should enable full fuzzy sorting of the autocomplete menu.

The current `:tree-sitter-subtree` has a bug for field-names when the
field name belongs to an unnamed child node. Take this ruby example:
def self.method_name
true
end
The subtree given by tree-sitter-cli is:
(singleton_method [2, 0] - [4, 3]
object: (self [2, 4] - [2, 8])
name: (identifier [2, 9] - [2, 20])
body: (body_statement [3, 2] - [3, 6]
(true [3, 2] - [3, 6])))
But the `:tree-sitter-subtree` output was
(singleton_method
object: (self)
body: (identifier)
(body_statement (true)))
The `singleton_method` rule defines the `name` and `body` fields in an
unnamed helper rule `_method_rest` and the old implementation of
`pretty_print_tree_impl` would pass the `field_name` down from the
named `singleton_method` node.
To fix it we switch to the [TreeCursor] API which is recommended by
the tree-sitter docs for traversing the tree. `TreeCursor::field_name`
accurately determines the field name for the current cursor position
even when the node is unnamed.

This fixes an edge case for completing shellwords. With a file
"a b.txt" in the current directory, the sequence `:open a\<tab>`
will result in the prompt containing `:open aa\ b.txt`. This is
because the length of the input which is trimmed when replacing with
completion is calculated on the part of the input which is parsed by
shellwords and then escaped (in a separate operation), which is lossy.
In this case it loses the trailing backslash.
The fix provided here refactors shellwords to track both the _words_
(shellwords with quotes and escapes resolved) and the _parts_ (chunks
of the input which turned into each word, with separating whitespace
removed). When calculating how much of the input to delete when
replacing with the completion item, we now use the length of the last
part.
This also allows us to eliminate the duplicate work done in the
`ends_with_whitespace` check.
There is some common code between Editor::focus_next and Editor::focus
that can be eliminated by refactoring Tree::focus_next into a function
that only returns the next ViewId.
The text within the command palette used a custom format to display
the keybinding for a command. This change switches to the key sequence
format that we use for pending keys and macros.

d6323b7cbc introduced a regression for
shell commands like `|`, `!`, and `<A-!>` which caused the new
selections to be incorrect. This caused a panic when piping (`|`)
would cause the new range to extend past the document end.
The paste version of this bug was fixed in
48a3965ab4.
This change also inherits the direction of the new range from the old
range and adds integration tests to ensure that the behavior isn't
broken in the future.
This adds in a couple more roots that are common in Scala.
- `build.sc` which is used in Mill
- `build.gradle` for Scala Gradle projects
- `.scala-build` for scala-cli projects
