§arborium-cpp

General-purpose language extending C with zero-overhead abstractions; see Stroustrup’s official overview at isocpp.org.


Inventor	Bjarne Stroustrup
Year	1985

§Usage

use arborium_cpp::language;
use tree_sitter_patched_arborium::Parser;

let mut parser = Parser::new();
parser.set_language(&language()).expect("Error loading cpp grammar");

let source_code = "/* your cpp code here */";
let tree = parser.parse(source_code, None).unwrap();
println!("{}", tree.root_node().to_sexp());

For most use cases, prefer the main arborium crate:

[dependencies]
arborium = { version = "*", features = ["cpp"] }

Or use this crate directly:

[dependencies]
arborium-cpp = "*"

§About Arborium

This crate is part of Arborium, a collection of tree-sitter grammars packaged as Rust crates, maintained by Amos Wenger.

This crate packages a parser.c file generated by the tree-sitter CLI. It exports a language() function returning the tree-sitter Language for cpp.

Why separate crates? Tree-sitter parsers can be large (some exceed 1MB of generated C). Splitting languages into separate crates means you only compile what you need, and parallel/incremental builds are more effective.

§Build Requirements

Rust: MSRV is 1.85.0 (Rust 2024 edition)
C compiler: This crate compiles C code via the cc crate

§Supported Targets

All major platforms: Linux, macOS, Windows
WebAssembly: wasm32-unknown-unknown (with custom sysroot)

§Upstream Grammar


Repository	tree-sitter/tree-sitter-cpp
Commit	`12bd6f7e96080d2e70ec51d4068f2f66120dde35`
License	MIT

To regenerate after upstream updates:

cargo xtask gen --name cpp

Found a grammar bug? Please report it to the upstream repository.

§Safety

This crate uses unsafe for FFI bindings to the tree-sitter C library. The unsafe surface is minimal and limited to what tree-sitter requires. The generated parser code is produced by tree-sitter’s own code generator.

§Versioning

Crate versions track Arborium releases, not upstream grammar versions. The upstream commit is recorded above. A major version bump occurs when grammar changes affect node names or structure (breaking for query consumers).

§License

Generated parser code (parser.c): MIT (from upstream grammar)
Arborium glue code: MIT OR Apache-2.0
