  • Types: number, string, boolean, array, object
  • Operators: +, -, *, /, ==, !=, &&, ||, ->
  • Standard library functions: math.*, string.*, array.*, io.*

⚡ Quick Actions

• Run File: Execute Infra files directly from VS Code
• Check Syntax: Validate syntax without execution
• Context menu integration for .if and .infra files

🐛 Error Detection

• Real-time syntax error checking
• Integration with Infra interpreter for accurate diagnostics
• Errors appear in the Problems panel with line/column information

🛠️ Language Features

• Bracket matching and auto-closing
• Smart indentation
• Comment toggling with // and # support
• Code folding support

🎨 Custom File Icons

Usage

Running Infra Files

1. Open any .if or .infra file
2. Click the play button in the editor title bar, or
3. Right-click and select "Run Infra File"

Syntax Checking

1. Open any .if or .infra file
2. Right-click and select "Check Syntax"
3. View results in the integrated terminal

Error Detection

• Errors appear automatically in the Problems panel
• Save the file to trigger error checking
• Hover over error markers for details

Infra Language Overview

Infra is a modern programming language with Python-like syntax and static typing support:

# Variables with type annotations
let score: number = 95
let message: string = "Hello, Infra!"
let active: boolean = true

# Functions with type checking
function calculateArea(length: number, width: number) -> number:
    return length * width

# Data structures
let numbers: [number] = [1, 2, 3, 4, 5]
let person: {name: string, age: number} = {
    name: "Alice",
    age: 30
}

# Control flow
if score >= 90:
    print("Excellent work!")
else:
    print("Keep trying!")

# Standard library
let result = math.sqrt(16)
let length = string.length("Hello")
array.push(numbers, 6)

Requirements

• Infra Interpreter: The extension requires the Infra language interpreter to be available in the parent directory (../)
• Cargo: Used to run the Rust-based Infra interpreter

Extension Settings

This extension contributes the following settings:

• Currently no configurable settings (coming in future versions)

Known Issues

• Error detection requires saving the file to trigger
• Performance may be slower for very large files
• Requires Infra interpreter in specific directory structure
