inject language based on file extension & shebang (#3970)
* inject language based on file extension

Nodes can now be captured with "injection.filename". If this capture
contains a valid file extension known to Helix, then the content will
be highlighted as that language.

* inject language by shebang

Nodes can now be captured with "injection.shebang". If this capture
contains a valid shebang line known to Helix, then the content will
be highlighted as the language the shebang calls for.

* add documentation for language injection

* nix: fix highlights

The `@` is now highlighted properly on either side of the function arg.

Also, extending the phases with `buildPhase = prev.buildPhase + ''''`
is now highlighted properly.

Fix highlighting of `''$` style escapes (requires tree-sitter-nix bump)

Fix `inherit` highlighting.

* simplify injection_for_match

Split out injection pair logic into its own method to make the overall
flow easier to follow.

Also transform the top-level function into a method on a
HighlightConfiguration.

* markdown: add shebang injection query

feat(debug): highlight current line (#5957)
Add new theme highlight keys, for setting the colour of the breakpoint
character and the current line at which execution has been paused at.
The two new keys are `ui.highlight.frameline` and `ui.debug.breakpoint`.
Highlight according to those keys, both the line at which debugging
is paused at and the breakpoint indicator.

Add an indicator for the current line at which execution is paused
at, themed by the `ui.debug.active` theme scope. Update various themes
to showcase how the new functionality works.

Better icons are dependent on #2869, and as such will be handled in the
future, once it lands.

Closes: #5952

Pascal Kuthe d63e570e0a treat replace/insertmode consistently, default to insert 2 years ago
Pascal Kuthe b1f7528090 fix snippet bugs and multicursor completion edgecases
Multicursor completions may overlap and therefore overlapping
completions must be dropped to avoid crashes. Furthermore, multicursor
edits might simply be out of range if the word before/after the cursor
is shorter. This currently leads to crashes, instead these selections
are now also removed for completions.

This commit also significantly refactors snippet transaction generation
so that tabstops behave correctly with the above rules. Furthermore,
snippet tabstops need to be carefully mapped to ensure their position
is correct and consistent with our selection semantics. Finally,
we now keep a partially updated Rope while creating snippet
transactions so that we can fill information into snippets that
depends on the position in the document.

Generalised to multiple runtime directories with priorities (#5411)
* Generalised to multiple runtime directories with priorities

This is an implementation for #3346.

Previously, one of the following runtime directories were used:

1. `$HELIX_RUNTIME`
2. sibling directory to `$CARGO_MANIFEST_DIR`
3. subdirectory of user config directory
4. subdirectory of path to helix executable

The first directory provided / found to exist in this order was used as a
root for all runtime file searches (grammars, themes, queries).

This change lowers the priority of `$HELIX_RUNTIME` so that the user
config runtime has higher priority. More significantly, all of these
directories are now searched for runtime files, enabling a user to override
default or system-level runtime files. If the same file name appears
in multiple runtime directories, the following priority is now used:

1. sibling directory to `$CARGO_MANIFEST_DIR`
2. subdirectory of user config directory
3. `$HELIX_RUNTIME`
4. subdirectory of path to helix executable

One exception to this rule is that a user can have a `themes`
directory directly in the user config directory that has higher piority
to `themes` directories in runtime directories. That behaviour has been
preserved.

As part of implementing this feature `theme::Loader` was simplified
and the cycle detection logic of the theme inheritance was improved to
cover more cases and to be more explicit.

* Removed AsRef usage to avoid binary growth

* Health displaying ;-separated runtime dirs

* Changed HELIX_RUNTIME build from src instructions

* Updated doc for more detail on runtime directories

* Improved health symlink printing and theme cycle errors

The health display of runtime symlinks now prints both ends of the
link.

Separate errors are given when theme file is not found and when the
only theme file found would form an inheritence cycle.

* Satisfied clippy on passing Path

* Clarified highest priority runtime directory purpose

* Further clarified multiple runtime details in book

Also gave markdown headings to subsections.

Fixed a error with table indentation not building
table that also appears present on master.

Pascal Kuthe aabc8af95d correctly store snapshots when repeating insert-mode actions
Repeating completions currently crates a savepoint when a completion
popup was triggered (so after the request completed). Just like for
normal completions the savepoint must be created at the request.

The occurrence of the completion request was previously not saved in
`last_insert`. To that end a new `InsertEvent::RequestCompletion`
variant has been added. When replayed this event creates a snapshot
that is "actived" by the `TriggerCompletion` event and subsequently
used during any `InsertEvent::CompletiuonApply` events.

Pascal Kuthe 8cb7cdfd7a discard stale completion requests
Completion requests are computed asynchronously to avoid common micro
freezes while editing. This means that once a completion request
completes, the state of the editor might have changed. Currently,
there is a check to ensure we are still in insert mode. However,
we also need to ensure that the view and document hasn't changed
to avoid accidentally using a savepoint with the wrong view/document.

Furthermore, the editor might request a new completion while the
previous completion request hasn't complemented yet. This can
lead to weird flickering or an outdated completion request replacing
a newer completion that has already completed (the LSP server
is not required to process completion requests in order). This change
also needed to ensure determinism/linear ordering so that completion
popup always correspond to the last completion request.

Pascal Kuthe e8898fd9a8 store multiple snapshots on the document at once
Fixing autocomplete required moving the document savepoint before the
asynchronous completion request. However, this in turn causes new bugs:

If the completion popup is open, the savepoint is restored when the
popup closes (or another entry is selected). However, at that point
a new completion request might already have been created which
would have replaced the new savepoint (therefore leading to incorrectly
applied complies).

This commit fixes that bug by allowing in arbitrary number of
savepoints to be tracked on the document. The savepoints are reference
counted and therefore remain valid as long as any reference to them
remains. Weak reference are stored on the document and any reference
that can not be upgraded anymore (hence no strong reference remain)
are automatically discarded.

Pascal Kuthe 2588fa3710 save selection before completion savepoint
Currently, the selection is not saved/restored when completion
checkpoints are applied. This is usually fine because undoing changes
usually restores maps selections back in insert mode. But this is not
always the case and especially problematic in the presence of
multi-cursor completions (since completions are applied relative to
the selection/cursor) and snippets (which can change the selection)

DynamicPicker: Recalculate column widths for new options (#6004)
This fixes blank row text in a DynamicPicker which is initially given
no options. This can happen for language servers which respond to
the workspace symbol request for an empty query with an empty list
of symbols, and that behavior is somewhat common since returning all
symbols as the spec suggests is very expensive.

For empty options, `Picker::new` calculated the widths of each column
as 0. We can recalculate the column widths when the new options are
set to fix this. This refactor is also a good opportunity to formalize
setting new options on a picker: besides setting the new options and
calculating column widths we also want to reset the cursor and rescore
the options.

lesleyrs 8dab8a0a03 Add shift-backspace keybind alias for backspace (#4937)
When the Kitty Keyboard Protocol is enabled, S-backspace is
distinguished from backspace with no modifiers. This is awkward when
typing because it's very easy to accidentally hold shift and press
backspace temporarily when typing capital letters.

Kakoune (which is also a Kitty Keyboard Protocol application) treats
S-backspace as backspace too:

feat(ui): deprecated completions (#5932)
* feat(ui): deprecated completions

Mark deprecated completions using strike-through
(CROSSED_OUT modifier). The deprection information
is taken either from the `deprecated` field of the
completion item or from the completion tags.

The field seems to be the older way of passing
the deprecated information and it was already
marked as deprecated for Symbol. In completion
item the field is still valid but it seems that
the LSP is moving in the general direction of using
tags for this kind of information and as such
relying on tags as well seems reasonable and
future-proof.

rework positioning/rendering and enable softwrap/virtual text (#5420)
* rework positioning/rendering, enables softwrap/virtual text

This commit is a large rework of the core text positioning and
rendering code in helix to remove the assumption that on-screen
columns/lines correspond to text columns/lines.

A generic `DocFormatter` is introduced that positions graphemes on
and is used both for rendering and for movements/scrolling.
Both virtual text support (inline, grapheme overlay and multi-line)
and a capable softwrap implementation is included.

lsp: Check server provider capabilities (#3554)
Language Servers may signal that they do not support a method in
the initialization result (server capabilities). We can check these
when making LSP requests and hint in the status line when a method
is not supported by the server. This can also prevent crashes in
servers which assume that clients do not send requests for methods
which are disabled in the server capabilities.

There is an existing pattern the LSP client module where a method
returns `Option<impl Future<Output = Result<_>>>` with `None` signaling
no support in the server. This change extends this pattern to the rest
of the client functions. And we log an error to the statusline for
manually triggered LSP calls which return `None`.

lsp: Resolve completion item asynchronously on idle-timeout (#4781)
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

Fix panic from two windows editing the same document (#4570)
* Clamp highlighting range to be within document

This fixes a panic possible when two vsplits of the same document
exist and enough lines are deleted from the document so that one of
the windows focuses past the end of the document.

* Ensure cursor is in view on window change

If two windows are editing the same document, one may delete enough of
the document so that the other window is pointing at a blank page (past
the document end). In this change we ensure that the cursor is within
view whenever we switch to a new window (for example with `<C-w>w`).

Fix debug assertion for diagnostic sort order (#4319)
The debug assertion that document diagnostics are sorted incorrectly
panics for cases like `[161..164, 162..162]`. The merging behavior
in the following lines that relies on the assertion only needs the
input ranges to be sorted by `range.start`, so this change simplifies
the assertion to only catch violations of that assumption.

Overlay all diagnostics with highest severity on top (#4113)
Here we separate the diagnostics by severity and then overlay the Vec
of spans for each severity on top of the highlights. The error
diagnostics end up overlaid on the warning diagnostics, which are
overlaid on the hints, overlaid on info, overlaid on any other severity
(default), then overlaid on the syntax highlights.

This fixes two things:

* Error diagnostics are now always visible when overlapped with other
  diagnostics.
* Ghost text is eliminated.
    * Ghost text was caused by duplicate diagnostics at the EOF:
      overlaps within the merged `Vec<(usize, Range<usize>)>` violate
      assumptions in `helix_core::syntax::Merge`.
    * When we push a new range, we check it against the last range and
      merge the two if they overlap. This is safe because they both
      have the same severity and therefore highlight.

The actual merge is skipped for any of these when they are empty, so
this is very fast in practice. For some data, I threw together an FPS
counter which renders as fast as possible and logs the renders per
second.

With no diagnostics, I see an FPS gain from this change from 868 FPS
to 878 (+1.1%) on a release build on a Rust file. On an Erlang file
with 12 error diagnostics and 6 warnings in view (233 errors and 66
warnings total), I see a decrease in average FPS from 795 to 790
(-0.6%) on a release build.

Automatically track pseudo-pending text (#4077)
This change automatically tracks pending text for for commands which use
on-next-key callbacks. For example, `t` will await the next key event
and "t" will be shown in the bottom right-hand corner to show that we're
in a pending state.

Previously, the text for these on-next-key commands needed to be
hard-coded into the command definition which had some drawbacks:

* It was easy to forget to write and clear the pending text.
* If a command was remapped in a custom config, the pending text would
  still show the old key.

With this change, pending text is automatically tracked based on the
key events that lead to the command being executed. This works even
when the command is remapped in config and when the on-next-key
callback is nested under some key sequence (for example `mi`).

Derive Document language name from languages.toml name key (#3338)
* 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.

* 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, language & files by score & then name (#2675)
* 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.

* Remove unnecessary reference

Add single width left margin for completion popup (#2728)
* 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 (#2711)
* 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

Fix scrollbar length proportional to total menu items (#2860)
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 :)
