Python bindings to the Tree-sitter incremental parsing library, exposing Parser, Tree, Node, and Query APIs for building concrete syntax trees from source code. It ships pre-compiled wheels with no library dependencies and supports loading separately installed language grammars.

Use cases

• parse source code into a syntax tree in Python
• build a code linter or analyzer
• extract symbols and structure from code files
• write syntax-aware code search queries
• power syntax highlighting for an editor
• incrementally reparse edited source code

When to choose

• you need fast, error-tolerant parsing of many programming languages from Python
• you want to query code with Tree-sitter's pattern query syntax
• you're building tooling like highlighters, linters, or refactoring tools

When to avoid

• you need a full compiler frontend with semantic analysis or type information
• you only need to parse Python itself and prefer the stdlib ast module
• you need a pure-Python solution without native extensions
