Quantum DSL (QTN) Language Support

Syntax highlighting and Language Server support for Photon Quantum 3 DSL (.qtn) files in Visual Studio 2022, including autocomplete, go-to-definition, hover information, and symbols.

.qtn is the data-definition language for Quantum's deterministic ECS — it declares components, structs, events, signals, inputs and globals that the Quantum code generator turns into C#.

Features

• Syntax highlighting — TextMate grammar covering declarations, modifiers, built-in Quantum types (FP, FPVector2, EntityRef, …), collections, attributes, literals and comments.
• Language Server features — autocomplete, hover information, go-to-definition, and symbols across your .qtn files.
• Document & workspace symbols — navigate types and members quickly.

Requirements

• Visual Studio 2022 (17.0+)
• The extension bundles its own Language Server; no extra setup is required.
