Tree-sitter TQL 🌳

This repository hosts the tree-sitter grammar for TQL, the Tenzir Query Language.

Features:

• 🚀 Complete syntax support for TQL pipelines, operators, and expressions
• 📝 Proper handling of significant newlines and pipe separators
• 🔢 Support for all TQL literal types, including strings, numbers, IP addresses, and durations
• 🔀 Control flow structures, including if, else, and match
• 📦 Module paths and function calls
• 💬 Line and block comments
• 🧠 Tree-sitter queries for highlights, indentation, folds, injections, and locals

Usage

See the official Tenzir documentation for editor setup instructions: Set up syntax highlighting.

Development

Contributions are welcome! 🎉

Setup

1. Clone the repository and install dependencies:

   git clone https://github.com/tenzir/tree-sitter-tql
   cd tree-sitter-tql
   npm install
   npm exec -- lefthook install

2. Regenerate the parser (and highlights) when needed:

   npm run generate

[!NOTE] Highlights, indentation, folding, and locals queries stay in sync because they are generated and committed alongside the parser. CI re-runs the generator and fails if the checked-in files would change, so always execute npm run generate after touching the grammar or related constants.

Playground

To interactively test the grammar:

npm run start
# or
npx tree-sitter playground

This opens a web interface where you can input TQL code and see the parse tree in real time.
