helix-syntax mostly existed for the sake of the build task which
checks and compiles the submodules. Since we won't be relying on
that process anymore, it doesn't end up making much sense to have
a very thin crate just for some functions that we could port to
helix-core.
The remaining build-related code is moved to helix-term which will
be able to provide grammar builds through the --build-grammars CLI
flag.
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
