Since tree-house is young and we've seen a few bugs that make it go
backwards, we should handle this case gracefully and just give up on
syntax highlighting with an error log.
This is meant to be minimal for now and is expected to change as the
config system evolves.
Features like word completion should be able to hook into this to
initialize or clear the word index when the toggle for the feature is
turned on or off (respectively).
The prompt was previously assuming that each grapheme cluster in the
line was single-width and single-byte. Lines like the one in the new
integration test would cause panics because the anchor attempted to
slice into a character.
This change rewrites the anchor and truncation code in the prompt to
account for Unicode segmentation and width. Now multi-width graphemes
can be hidden by multiple consecutive elipses - for example "十" is
hidden by "……" (2-width).

This fixes a deadlock when starting Helix with very many files, like
`hx runtime/queries/*/*.scm`. The tree-sitter query files don't have
an active language server on my machine and yet we were spawning a tokio
task to collect documentColors responses. We can skip that entirely.
Further debugging is needed to figure out why this lead to a deadlock
previously.
Since locals are handled during parsing instead of highlighting with
tree-house, we need to call `helix_core::syntax::Loader::set_scopes`
before parsing any documents. During `:config-reload` we previously
reloaded the `Loader` and re-parsed documents and _then_ updated the
theme. So documents were parsed before `Loader::set_scopes` was called
on the new loader.
With this change the `refresh_language_config` helper is inlined into
`refresh_config`. Updating the `Editor`'s `ArcSwap` of the loader is
done before updating the theme so that the `load_configured_theme`
helper can call `set_scopes` with on the new loader.
With a directory with spaces in the name (for example
`mkdir -p 'Temp/Abc Def'`), completing `Temp/Ab` would create a
completion item `'Temp/AbAbc Def'`. Now it correctly completes
`'Temp/Abc Def'`
On Windows for example the behavior of this function typically diverges
from the usual behavior on Unix. Instead of checking that the inserted
string starts with `'\n'` (untrue for for CRLF line endings) we need to
check that the first grapheme cluster in the string is a line ending.
(All line endings are single grapheme clusters.)
This fixes a regression from the refactor of the highlighters when
switching to tree-house. The old `StyleIter` used `renderer.text_style`
as the base style rather than `Style::default()` for syntax highlights.
The result was that any text not captured by a syntax highlight query
was styled with no foreground or background, defaulting to the
terminal's foreground/background. This could cause text in markdown
files to look off-colored depending on your terminal configuration.
(Though you wouldn't notice if your 'ui.text' theming matches your
terminal's theming.)
Previously the statusline `write` function only accepted a string
and optional Style, so all rendering functions converted text to
strings. Some elements write spans with `&'static str`s, however, making
this unnecessary since `Span<'a>` is a wrapper around `Cow<'a, str>` and
style, and a `Span<'static>` would outlive all required lifetimes.
Moreover many elements could produce `Span<'a>` according to the
lifetime in `RenderContext` in the future, potentially re-borrowing from
the Editor borrow, so this change could save allocations for many
file-type elements (with more future changes). This is not explored in
this patch since the statusline functions currently add bespoke padding
per-element, but with a future refactor to make spacing consistent this
could be possible.
This change refactors the write function to accept a `Span<'a>` and
rewrites some related code to fit the codebase better (preferring `for`
to iterator's `for_each` for example). The new code is more complicated
lifetime-wise but avoids allocations in these cases:
* spacer for mode name when a pane is not focused
* LSP spinner frames
* '●' (workspace) diagnostic indicators
* " W " workspace diagnostic prefix
* file modification indicators
* read-only indicators
* spacer element
... and opens the door to avoid allocation for file name elements in the
future.
If you configure a subset of severities to show in the workspace
diagnostics statusline element you can see the 'W' (and surrounding
space) without any diagnostic indicators. This is the case by default
as it's configured to show warnings and errors only - if you have only
hints in your workspace like if you open `application.rs` in Helix for
example then you would see the 'W' and no indicators.
This change checks that any of the configured diagnostics are non-zero
and bails early if there are none.
This type also exists on `Editor`. This change brings it to the
`Document` as well because the replacement for `Syntax` in the child
commits will eliminate `Syntax`'s copy of `syn_loader`. `Syntax` will
also be responsible for returning the highlighter and query iterators
(which will borrow the loader), so the loader must be separated from
that type.
In the long run, when we make a larger refactor to have
`Document::apply` be a function of the `Editor` instead of the
`Document`, we will be able to drop this field on `Document` - it is
currently only necessary for `Document::apply`. Once we make that
refactor, we will be able to eliminate the surrounding `Arc` in
`Arc<ArcSwap<syntax::Loader>>` and use the `ArcSwap` directly instead.
