Here we add syntax to the languages.toml languge
[[grammar]]
name = "<name>"
source = { .. }
Which can be used to specify a tree-sitter grammar separately of
the language that defines it, and we make this distinction for
two reasons:
* In later commits, we will separate this code from helix-core
and bring it to a new helix-loader crate. Using separate schemas
for language and grammar configurations allows for a nice divide
between the types needed to be declared in helix-loader and in
helix-core/syntax
* Two different languages may use the same grammar. This is currently
the case with llvm-mir-yaml and yaml. We could accomplish a config
that works for this with just `[[languages]]`, but it gets a bit
dicey with languages depending on one another. If you enable
llvm-mir-yaml and disable yaml, does helix still need to fetch and
build tree-sitter-yaml? It could be a matter of interpretation.
* Move runtime file location definitions to core
* Add basic --health command
* Add language specific --health
* Show summary for all langs with bare --health
* Use TsFeature from xtask for --health
* cargo fmt

Treesitter captures can contain multiple nodes like so:
```
(line_comment)+ @comment
```
This would match each line in a comment as a separate
`@comment` capture when what we actually want is the
whole set of contiguous `line_comment` nodes to be
captured under the `@comment` capture. This commit enables
this behaviour.
* impl auto pairs config
Implements configuration for which pairs of tokens get auto completed.
In order to help with this, the logic for when *not* to auto complete
has been generalized from a specific hardcoded list of characters to
simply testing if the next/prev char is alphanumeric.
It is possible to configure a global list of pairs as well as at the
language level. The language config will take precedence over the
global config.
* rename AutoPair -> Pair
* clean up insert_char command
* remove Rc
* remove some explicit cloning with another impl
* fix lint
* review comments
* global auto-pairs = false takes precedence over language settings
* make clippy happy
* print out editor config on startup
* move auto pairs accessor into Document
* rearrange auto pair doc comment
* use pattern in Froms
* Add injection regex for more languages
To support embedding them in other languages like markdown.
* Add llvm-mir highlighting
LLVM Machine IR is dumped as yaml files that can embed LLVM IR and
Machine IR.
To support this, add a llvm-mir-yaml language that uses the yaml
parser, but uses different injections to highlight IR and MIR.
* Update submodule with fixed multiline comments

* feat(lsp): configurable diagnostic severity
Allow severity of diagnostic messages to be configured.
E.g. allow turning of Hint level diagnostics.
Fixes: https://github.com/helix-editor/helix/issues/1007
* Use language_config() method
* Add documentation for diagnostic_severity
* Use unreachable for unknown severity level
* fix: documentation for diagnostic_severity config
* Add treesitter textobject queries
Only for Go, Python and Rust for now.
* Add tree-sitter textobjects
Only has functions and class objects as of now.
* Fix tests
* Add docs for tree-sitter textobjects
* Add guide for creating new textobject queries
* Add parameter textobject
Only parameter.inside is implemented now, parameter.around
will probably require custom predicates akin to nvim' `make-range`
since we want to select a trailing comma too (a comma will be
an anonymous node and matching against them doesn't work similar
to named nodes)
* Simplify TextObject cell init
* allow language.config (in languages.toml) to be passed in as a toml object
* Change config field for languages from json string to toml object
* remove indents on languages.toml config
* fix: remove patch version from serde_json import in helix-core
* Use same tree-sitter-zig as upstream/master
