tree-sitter-wasm-build-tool
A crate to easily allow tree-sitter parsers to compile to Rust's
wasm32-unknown-unknown
target.
Currently, this only works with parsers that do not make use of an external C++ scanner.
It is meant to be used in build scripts, typically only if some
wasm
or
c2rust
feature is enabled.
For example:
let src_dir = std::path::Path::new("src");
let mut c_config = cc::Build::new();
c_config.include(src_dir);
c_config
.flag("-Wno-unused-parameter")
.flag("-Wno-unused-but-set-variable")
.flag("-Wno-trigraphs");
let parser_path = src_dir.join("parser.c");
c_config.file(&parser_path);
#[cfg(feature = "c2rust")]
tree_sitter_wasm_build_tool::add_wasm_headers(&mut c_config).unwrap();
c_config.compile("parser");
println!("cargo:rerun-if-changed={}", parser_path.to_str().unwrap());
The only public function is add_wasm_headers
. See its documentation for some
more information.
