This extension provides enhanced syntax highlighting for Terra, a low-level system programming language that is closely integrated with Lua. It aims to support not only basic Terra syntax, but also language constructs that blend Terra and Lua, enabling a smooth development experience when working with hybrid Terra/Lua codebases.
Features
Terra Keywords & Types: Highlights all Terra-specific keywords and types (e.g., terra, struct, int32, float, etc.).
Lua Integration: Includes embedded Lua syntax highlighting, ensuring that Lua code within Terra files also benefits from full syntax support.
Quoted Expressions: Special handling for Terra’s quoted expressions using backticks (e.g., `a, `[ something ]), providing a clearer distinction in your code.
Inline C Integration: Supports inline C code blocks introduced by terralib.includecstring, applying C syntax highlighting to the embedded code.
ASDL Grammar Blocks: Provides syntax highlighting within :Define[[ ... ]] blocks for ASDL grammar definitions, highlighting keywords (module, attributes, unique) and tokens (=, |, ?, *, {, }, etc.).

Requirements
VS Code (latest stable recommended)
Lua syntax support (either built-in or via a Lua extension) for best results when embedding Lua code.
No other special dependencies are required.
Extension Settings
This extension currently does not add any custom VS Code settings.
All highlighting behavior is controlled by the extension’s grammar definitions and your current theme.
Known Issues
State-dependent highlighting (e.g., dynamically recognized variable names after asdl.NewContext()) is not possible due to the limitations of TextMate grammars.
Certain complex Terra/Lua blends may not be highlighted perfectly, but most common patterns are supported.
Release Notes
1.0.0
Initial release:
Terra keywords, numbers, types, and strings highlighted.
Basic Lua syntax highlighting embedded.
Quoted expressions and inline C code blocks recognized.
