|
|
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
