## What it is
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

## Facets
- artifact type: library
- maturity: active
- function: parser, developer-tools
- domain: parsers, programming-languages, developer-tools
- platform: python, cross-platform
- tags: tree-sitter, syntax-tree, incremental-parsing, code-analysis, bindings
