What it is and what it does
tree-sitter-c is a grammar module for the tree-sitter parsing framework that provides syntax tree representation of C source code. It is adapted from the ISO C99 standard grammar and enables incremental parsing and structural code analysis. The package ships as precompiled binaries for common platforms (x86_64, ARM, Windows, macOS), reducing installation friction.
Developers use it to build tools that need to understand C code structure—linters, code formatters, refactoring tools, or static analysis systems. The package supplies only the C language grammar rules and requires the tree-sitter core framework to function. No runtime dependencies are declared in the package metadata.
Use it for
- Build a C code linter or style checker that understands syntactic structure.
- Implement code analysis for an IDE or editor plugin.
- Extract function signatures or variable declarations from C source files.
- Create a code refactoring tool that preserves C syntax during transformations.
- Analyze C codebases for code quality or structural patterns.
