tree-sitter · GitHub
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 languageFast enough to parse on every keystroke in a text editorRobust enough to provide useful results even in the presence of syntax errorsDependency-free so that the runtime library (which is written in pure C) can
be embedded in any application
