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.

* auto pair-removal
Fixes https://github.com/helix-editor/helix/issues/1673
* autopairs removal: use doc autopairs
* autopairs-removal: limit to one-char selections
* use single_grapheme() to check if range is one char
* fix errouneous deletes of " and other symmetric autopairs when at buffer start

* add statusline element to display file line endings
* run cargo fmt --all
* change the word *ending* from plural to singular
* support for the unicode-lines feature flag
* Add lsp signature help
* Do not move signature help popup on multiple triggers
* Highlight current parameter in signature help
* Auto close signature help
* Position signature help above to not block completion
* Update signature help on backspace/insert mode delete
* Add lsp.auto-signature-help config option
* Add serde default annotation for LspConfig
* Show LSP inactive message only if signature help is invoked manually
* Do not assume valid signature help response from LSP
Malformed LSP responses are common, and these should not crash the
editor.
* Check signature help capability before sending request
* Reuse Open enum for PositionBias in popup
* Close signature popup and exit insert mode on escape
* Add config to control signature help docs display
* Use new Margin api in signature help
* Invoke signature help on changing to insert mode
* feat(statusline): add the file type (language id) to the status line
* refactor(statusline): move the statusline implementation into an own struct
* refactor(statusline): split the statusline implementation into different functions
* refactor(statusline): Append elements using a consistent API
This is a preparation for the configurability which is about to be
implemented.
* refactor(statusline): implement render_diagnostics()
This avoid cluttering the render() function and will simplify
configurability.
* feat(statusline): make the status line configurable
* refactor(statusline): make clippy happy
* refactor(statusline): avoid intermediate StatusLineObject
Use a more functional approach to obtain render functions and write to
the buffers, and avoid an intermediate StatusLineElement object.
* fix(statusline): avoid rendering the left elements twice
* refactor(statusline): make clippy happy again
* refactor(statusline): rename `buffer` into `parts`
* refactor(statusline): ensure the match is exhaustive
* fix(statusline): avoid an overflow when calculating the maximal center width
* chore(statusline): Describe the statusline configurability in the book
* chore(statusline): Correct and add documentation
* refactor(statusline): refactor some code following the code review
Avoid very small helper functions for the diagnositcs and inline them
instead.
Rename the config field `status_line` to `statusline` to remain
consistent with `bufferline`.
* chore(statusline): adjust documentation following the config field refactoring
* revert(statusline): revert regression introduced by c0a1870
* chore(statusline): slight adjustment in the configuration documentation
* feat(statusline): integrate changes from #2676 after rebasing
* refactor(statusline): remove the StatusLine struct
Because none of the functions need `Self` and all of them are in an own
file, there is no explicit need for the struct.
* fix(statusline): restore the configurability of color modes
The configuration was ignored after reintegrating the changes of #2676
in 8d28f95.
* fix(statusline): remove the spinner padding
* refactor(statusline): remove unnecessary format!()
Ctrl-based shortcuts are common in numerous applications.
This change:
- Adds Ctrl+{Left/Right/Backspace/Delete} for word-wise movement/deletion in prompt, picker, …
- Removes Alt-Left and Alt-Right in prompt, picker, …
- Adds Alt-Delete in insert mode for forward word deletion
In some terminals, Alt-Backspace might not work because it is ambigous.
See: https://github.com/helix-editor/helix/pull/2193#issuecomment-1105042501
Hence, Alt alternative is not removed.
