This extension provides syntax highlighting for the Lynx declarative modeling language.

Features

• Syntax Highlighting: Complete syntax highlighting for Lynx language constructs
• Language Configuration: Automatic bracket matching, indentation, and folding
• Comment Support: Line comments (//) and block comments (/* */)

Supported Language Features

Functions (Yellow)

• minimize, maximize - Optimization directives
• filter, sum, firstTrue - Built-in functions
• assert, Has - Utility functions

Keywords (Purple)

• type, alias - Type declarations
• objective, suchThat - Optimization parameters
• true, false - Boolean literals

Types

• Primitive Types: Bool, Integer, Float, String, int, float, str, bool
• Logic Types: All, Any, Not, Exactly, AtLeast, AtMost, Free, Has
• Custom Types: Capitalized identifiers (e.g., Color, Wheel, Price)

Operators

• Range: .., ... (spread)
• Assignment: =
• Comparison: ==, !=, <=, >=, <, >
• Arithmetic: +, -, *, /
• Logical: &&, ||, !
• Lambda: ->

Special Constructs

• Attributes: @attributeName
• Global Context: *
• String Literals: "text"
• Numbers: Integers and floats
• Comments: // line comment and /* block comment */

Installation

1. Copy the vscode-lynx-extension folder to your VS Code extensions directory:

   • Windows: %USERPROFILE%\\.vscode\\extensions\\
   • macOS: ~/.vscode/extensions/
   • Linux: ~/.vscode/extensions/

2. Restart VS Code

3. Open any .lynx file to see syntax highlighting in action

Example

// Type declaration with attributes
type Color : Bool {
    @tag : str,
}

// Variable assignment
red = Color(tag = "red")

// Range expression
z = -2..1

// Logic operation
constraint = All(x, y, z)

// Optimization
solution = minimize(
    objective = bike.totalPrice,
    suchThat = All(bike, constraint)
)

Development

To modify or extend the syntax highlighting:

1. Edit syntaxes/lynx.tmLanguage.json for syntax rules
2. Edit language-configuration.json for language behavior
3. Update package.json for extension metadata
