Bob Language Extension for VS Code

This extension provides syntax highlighting and language support for the Bob programming language in Visual Studio Code and Cursor.

Features

• Syntax Highlighting: Full syntax highlighting for Bob language constructs
• Code Snippets: Useful code snippets for common Bob patterns
• Auto-closing Brackets: Automatic bracket and quote pairing
• Indentation: Smart indentation for Bob code blocks
• Comments: Support for line and block comments
• Folding: Code folding support with region markers

Supported Syntax

Keywords

• Control flow: if, else, while, for, break, continue, return
• Variable declaration: var
• Function declaration: func
• Classes and OOP: class, extends, extension, this, super
• Logical operators: and, or, not

Built-in Functions

• print(), assert(), input(), type(), toString(), toNumber(), toInt(), time(), sleep(), printRaw()
• Arrays/Dictionaries (preferred method style): arr.len(), arr.push(...), arr.pop(), dict.len(), dict.keys(), dict.values(), dict.has()
• Global forms still available: len(x), push(arr, ...), pop(arr), keys(dict), values(dict), has(dict, key)
• Misc: random(), eval()

Data Types

• Numbers (integers, floats, binary 0b1010, hex 0xFF)
• Strings (single and double quoted)
• Booleans (true, false)
• None value (none)
• Arrays ([1, 2, 3])

Operators

• Arithmetic: +, -, *, /, %
• Comparison: ==, !=, <, >, <=, >=
• Logical: &&, ||, !
• Bitwise: &, |, ^, <<, >>, ~
• Compound assignment: +=, -=, *=, /=, %=, &=, |=, ^=, <<=, >>=
• Ternary: condition ? valueIfTrue : valueIfFalse
• String multiplication: "hello" * 3

Installation

From Source

1. Clone this repository
2. Run npm install to install dependencies
3. Run npm run compile to build the extension
4. Press F5 in VS Code to launch the extension in a new window

Manual Installation

1. Copy the extension files to your VS Code extensions directory
2. Restart VS Code
3. Open a .bob file to see syntax highlighting

Usage

Code Snippets

Type the following prefixes and press Tab to insert code snippets:

• func - Function definition
• if - If statement
• ifelse - If-else statement
• while - While loop
• for - For loop
• var - Variable declaration
• print - Print statement
• assert - Assert statement
• anon - Anonymous function
• return - Return statement
• break - Break statement
• continue - Continue statement
• comment - Comment block
• test - Test function
• array - Array declaration
• arrayaccess - Array access
• arrayassign - Array assignment
• len - Array length
• push - Array push
• pop - Array pop
• random - Random number
• sleep - Sleep function
• printraw - Print raw
• eval - Eval function

File Association

Files with the .bob extension will automatically be recognized as Bob language files.

Example

// This is a comment
var message = "Hello, Bob!";
print(message);

// Array operations (method style)
var numbers = [1, 2, 3, 4, 5];
print("Array length: " + numbers.len());
numbers.push(6);
print("Popped: " + numbers.pop());
print("First element: " + numbers[0]);

// Function with ternary operator
func factorial(n) {
    if (n <= 1) {
        return 1;
    }
    return n * factorial(n - 1);
}

var result = factorial(5);
var status = result > 100 ? "large" : "small";
assert(result == 120, "Factorial calculation failed");

// String multiplication
var repeated = "hello" * 3;  // "hellohellohello"
