This function was never used and will be superseded by
`RopeSliceExt::is_grapheme_boundary` (which accepts a byte index rather
than a character index) once we transition to Ropey v2. In the meantime
any callers should convert to byte index and use the `RopeSliceExt`
extension rather than form new dependencies on this.
This fixes a regression from the switch to tree-house with one of the
custom predicates in indent queries: `#not-kind-eq?`. This predicate
should be allowed to be written multiple times in a pattern. For example
in the Go indents:
; Switches and selects aren't indented, only their case bodies are.
; Outdent all closing braces except those closing switches or selects.
(
(_ "}" @outdent) @outer
(#not-kind-eq? @outer "select_statement")
(#not-kind-eq? @outer "type_switch_statement")
(#not-kind-eq? @outer "expression_switch_statement")
)
So instead of an `Option<T>` of one we need a `Vec<T>` and we need to
check that all of these predicates are individually satisfied (basically
`iter().all(/* node kind is not expected kind for that capture */)`).
This avoids using any custom configuration in a user-defined
`languages.toml` config for the syntax test cases. The test cases should
only use the builtin `languages.toml` config.
Also the xtask crate reimplemented `default_lang_loader` and
`default_lang_config`. These functions are replaced with calls into
`helix_core`.
`InactiveQueryCursor::new` might reuse a query cursor from a
thread-local cache if one is available, rather than create a new cursor.
Currently tree-house does not reset cached cursors back to defaults
(i.e. byte range and match limit). For now we can patch around this here
but eventually this should be fixed in `tree-house` upstream. Then this
patch can be reverted.
In practice this caused textobjects like `]f` to get "stuck" trying to
move to the next function if it was out of the current view. This is
because the highlight query cursor sets the range of the cursor to the
current viewport. We can reset the byte range to defaults to fix the
textobject behavior.
The switch to tree-house accidentally dropped some shebang parsing code
from the loader's function to detect by shebang. This change restores
that. The new code is slightly different as it's using a `regex_cursor`
regex on the Rope rather than eagerly converting the text to a
`Cow<str>` and running a regular regex across it.
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.
