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.
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.
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).

* 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
* 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!()
* Add mode specific styles
In similar vein to neovim's lualine and similar statusline packages this
allows helix users to style their mode based on which mode it is thus
making each mode more visually distinct at a glance
* Add an example based on rosepine
* Add editor.colors-mode config
* Document statusline mode styles
- Simplified match statements by destructuring MouseEvent struct
at the top and then matching on event.kind.
- Extracted out closures for calculating (1) position and view
of mouse click and (2) gutter coordinates and view of mouse click.
* check selection's visible width when copying on mouse click
Mouse-click-up copies the selection produced by dragging. The event
is ignored if the selection has a width of 1 though so you don't
copy when clicking rather than dragging. The current check copies
text when it has a visible width of 1 but is actually multiple
characters in the rope like a CRLF line-ending. With this change
we check the unicode width of the character(s) in the selection
rather than the range length, so clicking on a CRLF line-ending
does not copy.
* use range.fragment to simplify getting the primary selection width
The command palette previously used + as a delimiter for denoting
a single key in a key sequence, (like C+w). This was at odds with
how the statusline displayed them with pending keys (like <C-w>).
This patch changes the palette formatting to the statusline formatting
* Default rulers color to red
Currently if the theme a user is using doesn't have `ui.virtual.rulers`
set and they set up a ruler it just fails silently making it really hard
to figure out what went wrong. Did they set incorrectly set the ruler?
Are they using an outdated version of Helix that doesn't support rulers?
This happened to me today, I even switched to the default theme with
the assumption that maybe my theme just doesn't have the rulers setup
properly and it still didn't work.
Not sure if this is a good idea or not, feel free to suggest better
alternatives!
* Use builtin Style methods instead of Bevy style defaults
Co-authored-by: Michael Davis <mcarsondavis@gmail.com>
* Only default the style if there's no ui or ui.virtual
* Update themes style from ui.virtual to ui.virtual.whitespace
* Revert ui.virtual change in onelight theme
* Prefer unwrap_or_else

* feat(theme): add separate diagnostic colors
This commit adds separate diagnostic highlight colors for the different
types of LSP severities. If the severity type doesn't exist or is
unknown, we use some fallback coloring which was in use before this
commit.
Some initial color options were also added in the theme.toml
Resolves issue #2157
* feat(theme): add docs for new diagnostic options
* feat(theme): adjust defaults & reduce redundancy
- the different colors for different diagnostic severities are now
disabled in the default theme, instead diagnostics are just generally
underlined (as prior to the changes of this feature)
- the theme querying is now done once instead of every iteration in the
loop of processing every diagnostic message
During a single HighlightEvent::Source, the highlight spans do not
change and we can merge them into a single style at the beginning
of the event and use it instead of re-computing it for every grapheme
This avoids costly conversions via byte_to_char (which are then
reversed back into bytes internally in Ropey).
Reduces time spent in slice/byte_to_char from ~24% to ~5%.
