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: rand.random(), eval.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

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"
