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

* 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.

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.

Use indoc to fix tests
Fix line-ending on test input
* Refactor menu::Item to accomodate external state
Will be useful for storing editor state when reused by pickers.
* Add some type aliases for readability
* Reuse menu::Item trait in picker
This opens the way for merging the menu and picker code in the
future, since a picker is essentially a menu + prompt. More
excitingly, this change will also allow aligning items in the
picker, which would be useful (for example) in the command palette
for aligning the descriptions to the left and the keybinds to
the right in two separate columns.
The item formatting of each picker has been kept as is, even though
there is room for improvement now that we can format the data into
columns, since that is better tackled in a separate PR.
* Rename menu::Item::EditorData to Data
* Call and inline filter_text() in sort_text() completion
* Rename diagnostic picker's Item::Data
* Sort themes by score & then name
Previously the themes were appearing unordered after typing ':theme '.
This sorts them first by fuzzy score and then by name so that they
generally appear in a more ordered fashion in the initial list.
The sort by name does not really pay off when there is a score so an
alternative approach would be to sort by name if there is string to
fuzzy match against and otherwise sort by score.
I've lowercased the names as that avoids lower case & upper case letters
being sorted into separate groups. There might be a preferable approach
to that though.
* Sort language & files by score then name
And change to use sort_unstable_by instead of sort_unstable_by_key as it
allows us to avoid some allocations.
I don't fully understand the flow of the 'filename_impl' function but
this seems to deliver the desired results.

- 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.
* Add single width left margin for completion popup
* Clear with ui.menu style before rendering menu
When rendering a completion popup, the popup component will clear
the area with ui.popup and then the menu component would draw over
it using a table component. We remove the left edge of the area
before passing it to the table component (so that it will be left
as padding), and the table component uses ui.menu as the style.
If ui.menu and ui.popup are different the left edge of the popup
will look different from the rest of the popup. We avoid this by
clearing the whole area with ui.menu in Menu::render
* 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
* redetect indent and line endings after language server replaces document
* removes nested if
* always redetect indent and line endings after format
This reverts commit 764d14f55894dc7213e48022dfa0f91829b8ef59.
The scrollbar length used to increase with more entries in the menu,
which was counter-intuitive to how scrollbars worked in most
applications. Turns out there was a typo in the floor division
implementation :)
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
* feat: make `move_vertically` aware of tabs and wide characters
* refactor: replace unnecessary checked_sub with comparison
* refactor: leave pos_at_coords unchanged and introduce separate pos_at_visual_coords

* refactor: use `pos_at_visual_coords` in `text_pos_at_screen_coords`
* feat: make `copy_selection_on_line` aware of wide characters
* 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!

During write-quit, if the file fails to be written for any reason, helix
will still quit without saving the changes. This fixes this behavior by
introducing fallibility to the asynchronous job queues. This will also
benefit all contexts which may depend on these job queues.
Fixes#1575
When a new View of a Document is created, a default cursor of 0, 0 is
created, and it does not get normalized to a single width cursor until
at least one movement of the cursor happens. This appears to have no
practical negative effect that I could find, but it makes tests difficult
to work with, since the initial selection is not what you expect it to be.
This changes the initial selection of a new View to be the width of the
first grapheme in the text.
* Use new macro syntax for encoding sequences of keys
* Make convenience helpers for common test pattern
* Use indoc for inline indented raw strings
* Add feature flag for integration testing to disable rendering
- Add file-picker.follow-symlinks configuration option (default is true), this
also controls if filename and directory completers follow symlinks.
- Update FilePicker to set editor error if opening a file fails, instead of
panicing.
Fix#1548Fix#2246
In certain circumstances it was possible to get into an infinite loop
when replaying macros such as when different macros attempt to replay
each other.
This commit adds changes to track which macros are currently being
replayed and prevent getting into infinite loops.
When a goto command is cancelled, the jumplist should remain unchanged.
This commit delays saving the current selection to the jumplist until
jumping to a reference.
