Add this crate, and the language-specific crates for whichever languages you want to parse, to your Cargo.toml:
[dependencies]
tree-sitter-tags = "0.19"
tree-sitter-javascript = "0.19"
tree-sitter-python = "0.19"Create a tag context. You need one of these for each thread that you're using for tag computation:
use tree_sitter_tags::TagsContext;
let context = TagsContext::new();Load some tagging queries from the queries directory of some language repositories:
use tree_sitter_tags::TagsConfiguration;
let python_config = TagsConfiguration::new(
tree_sitter_python::language(),
tree_sitter_python::TAGGING_QUERY,
"",
).unwrap();
let javascript_config = TagsConfiguration::new(
tree_sitter_javascript::language(),
tree_sitter_javascript::TAGGING_QUERY,
tree_sitter_javascript::LOCALS_QUERY,
).unwrap();Compute code navigation tags for some source code:
let tags = context.generate_tags(
&javascript_config,
b"class A { getB() { return c(); } }",
None,
);
for tag in tags {
println!("kind: {:?}", tag.kind);
println!("range: {:?}", tag.range);
println!("name_range: {:?}", tag.name_range);
println!("docs: {:?}", tag.docs);
}
