I’m pleased to announce the release of tree-sitter-objectscript, a new open-source tree-sitter grammar that brings first-class ObjectScript support to modern editors. If you caught the preview at READY ’25, you’ll be glad to know it’s now up on Github:

• Fast & Precise Parsing: A powerful grammar for ObjectScript, enabling real-time syntax parsing, smart highlighting, and structural editing in modern code editors.
