* fix: Recalculate completion when going through prompt history
* Update completion when the prompt line is changed
It should not be possible to update the line without also updating the
completion since the completion holds an index into the line.
* Fix Prompt::with_line recalculate completion
with_line was the last function where recalculate completion had to be
done manually. This function now also recalculates the completion so
that it's impossible to forget.
* Exit selection when recalculating completion
Keeping the selection index when the completion has been recalculated
doesn't make sense. This clears the selection automatically, removing
most needs to manually clear it.
* Remove &mut on save_filter

It was starting to diverge as the normal exit code was restoring the prompt but the panic code
wasn't, and the panic code was disabling bracketed paste but the normal code wasn't.
This changes the panic path slightly in that we won't disable raw mode if exiting alternate screen
and disabling bracketed paste fails. If that happens, things are so busted I don't think it matters
anyway.
Fixes a panic with a config like:
[keys.normal.space]
x = [":buffer-close"]
by bailing out of the command-execution handling if the document
doesn't exist after handling a command.
This refactor changes the overall structure of the goto_ts_object_impl
command without removing any functionality from its behavior. The
refactored motion:
* acts on all selections instead of reducing to one selection
* may be repeated with the `repeat_last_motion` (A-.) command
* informs the user when the syntax-tree is not accessible in the current buffer
This is invalid according to the [LSP spec]:

So we should discard the message when the language server is not
yet initialized. This can happen if the server sends
textDocument/publishDiagnostics before responding to the initialize
request. clojure-lsp appears to exhibit this behavior in the wild.
[LSP Spec]: https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#initialize
This change adds documents to the view's document history Vec.
(This is used by `ga` for example to access the last buffer.)
Previously, a sequence like so would have confusing behavior:
1. Open file A: any document with an active language server
2. Find some definition that lives in another file - file B - with `gd`
3. Jump back in the jumplist with `C-o` to file A
4. Use `ga` intending to switch back to file B
The behavior prior to this change was that `ga` would switch to file
A: you could not use `ga` to switch to file B.
When changing focus, the lookup with `current!` may change the
view and end up executing mode transition hooks on the newly
focused view. We should use the same view and document to execute
mode transition hooks so that switching away from a view triggers
history save points.
* Derive Document language name from `languages.toml` `name` key
This changes switches from deriving the language name from the
`languages.toml` `scope` key to `name` (`language_id` in the
`LanguageConfiguration` type). For the most part it works to derive the
language name from scope by chopping off `source.` or `rsplit_once` on
`.` but for some languages we have now like html (`text.html.basic`),
it doesn't. This also should be a more accurate fallback for the
`language_id` method which is used in LSP and currently uses the
`rsplit_once` strategy.
Here we expose the language's name as `language_name` on `Document` and
replace ad-hoc calculations of the language name with the new method.
This is most impactful for the `file-type` statusline element which is
using `language_id`.
* Use `Document::language_name` for the `file-type` statusline element
The `file-type` indicator element in the statusline was using
`Document::language_id` which is meant to be used to for telling
Language Servers what language we're using. That works for languages
with `language-server` configurations in `languages.toml` but shows
text otherwise. The new `Document::language_name` method from the
parent commit is a more accurate way to determine the language.

* Update description of `m` textobject to its actual functionality
Sometime recently the functionality of `m` was changed to match the
nearest pair to the cursor, rather than the former functionality of
matching the pair only if the cursor was on one of the brace characters
directly.
* Rename surround methods to reflect that they work on pairs
The current naming suggests that they may work generally on any
textobject, whereas their implementation really focuses on pairs.
* Change description of m textobject to match actual functionality
The current implementation of `m` no longer merely looks at the pair
character the cursor is on, but actually will search for the pair
(defined in helix-core/src/surround.rs) that encloses the cursor, and
not the entire selection.

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).

These are read-line-like bindings which we'd like to minimize in
insert mode in general.
In particular these two are troublesome if you have a low
`editor.idle-timeout` config and are using LSP completions: the
behavior of C-n/C-p switches from moving down/up lines to moving
down/up the completion menu, so if you hit C-n too quickly
expecting to be in the completion menu, you'll end up moving down
a line instead. Using C-p moves you back up the line but doesn't
re-trigger the completion menu. This kind of timing related change
to behavior isn't realistically that big of a deal but it can be
annoying.
* Fix tab highlight when tab is partially visible
* Make it style based, and not truncation based
Dealing with truncating is a mess, especially when it comes to wide
unicode graphemes. This way it should work no matter what.
* Inline style calculation into branches
* Fix incorrect indent guide styling
Before the indent guides on top of whitespace inherited the theme
from them. Now they do not.
* Fix dark_plus theme indent_guides
* Use whitespace style as fallback for indent-guide
* Fix dark_plus theme indent_guides
* Move indent_guide style patching out of loop
* Avoid setting stdin handle when not necessary
Avoid setting the stdin handle in `shell_impl` when the input argument
is None.
This permits to run commands with no stdin with :sh
* refactoring to avoid code duplication
* making clippy happy
* Process variable name fix
Indent style may change when choosing a language with `:set-language`.
Line-endings most likely will not change, but `:set-language` should
have a similar effect as reloading a file (`:reload`), plus the two
are currently grouped in the implementation and line-ending detection
is not particularly expensive.
* Change default formatter for any language
* Fix clippy error
* Close stdin for Stdio formatters
* Better indentation and pattern matching
* Return Result<Option<...>> for fn format instead of Option
* Remove unwrap for stdin
* Handle FormatterErrors instead of Result<Option<...>>
* Use Transaction instead of LspFormatting
* Use Transaction directly in Document::format
* Perform stdin type formatting asynchronously
* Rename formatter.type values to kebab-case
* Debug format for displaying io::ErrorKind (msrv fix)
* Solve conflict?
* Use only stdio type formatters
* Remove FormatterType enum
* Remove old comment
* Check if the formatter exited correctly
* Add formatter configuration to the book
* Avoid allocations when writing to stdin and formatting errors
* Remove unused import

The language server sends a char offset range within the
signature help label text to highlight as the current parameter,
but helix uses byte offset ranges for rendering highlights. This
was brought up in the [review of the original signature help PR][1],
but the ranges were being highlighted correctly, and there were no
out of bound or indexing panics. Turns out rust-analyzer was
[incorrectly sending byte offsets] instead of char offsets and this
made it seem like all was well and good with offsets in helix during
initial testing.
