Rust
An incremental parsing system for programming tools

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
