Module cpp_tree_sitter 

Lightweight C/C++ parser using [tree-sitter-cpp].

This module provides a fast, zero‑dependency alternative to Clang for extracting call‑graph facts from C and C++ source code. It does not perform semantic analysis (types, overload resolution); it only produces syntactic nodes suitable for building a call graph.

Supported node kinds

• Function – function definitions, declarations, and template instantiations,
• Class – class/struct/union/interface definitions, including template specialisations,
• CallSite – call expressions,
• Variable – variable declarations outside parameter lists,
• Parameter – parameter declarations inside parameter lists.

Class detection

Unlike the original implementation, this version correctly reads the name field of class_specifier, struct_specifier and interface_specifier nodes, which contains the class name as a type_identifier or identifier. Template parameters are ignored.

Example

use icb_parser::cpp_tree_sitter::parse_cpp_file;

let code = r#"
    template <typename T>
    class MyClass {
        void method() {}
    };
"#;
let facts = parse_cpp_file(code).unwrap();
assert!(facts.iter().any(|n| n.kind == icb_common::NodeKind::Class
    && n.name.as_deref() == Some("MyClass")));

Functions

function_name 🔒

Extract the function name from a function definition/declaration node.

parent_kind_is 🔒

Check whether the node’s immediate parent has the expected kind.

parse_cpp_file

Parse a C/C++ source file and return a flat list of facts.

traverse_node 🔒
