Use Cases & Benefits
- Provides an incremental parsing system that builds and updates concrete syntax trees for source code efficiently.
- Enables fast, robust parsing on every keystroke with no external dependencies, suitable for embedding in various applications.
- Use for integrating real-time syntax highlighting and error detection in code editors.
- Use for building language-aware code analysis and refactoring tools that require up-to-date syntax trees.
- Use for developing custom parsers for any programming language with support for incremental updates.
About tree-sitter
tree-sitter
Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. Tree-sitter aims to be:
- General enough to parse any programming language
- Fast enough to parse on every keystroke in a text editor
- Robust enough to provide useful results even in the presence of syntax errors
- Dependency-free so that the runtime library (which is written in pure C) can be embedded in any application
