ddeLang Support

A Visual Studio Code extension that adds syntax highlighting for the ddeLang programming language.

Features

• Syntax highlighting for:
  • Numbers (integers and decimals)
  • Strings (single and double quoted)
  • Booleans (true, false)
  • Identifiers
  • Control keywords (if, elseif, else, return, ...)
  • Operators (+, -, *, /, =)
  • Comparators (==, !=, <=, >=, <, >)
  • Commas and semicolons
  • Brackets ({}, ())
  • Others

Language Overview

ddeLang is a simple, custom programming language with a syntax inspired by JavaScript, but cleaner and more lightweight. It is currently a work in progress, but more features will be added soon.

Example Code

x = random(1, 10);

print('The value of x is', x, "and it's of type", typeof(x));

y = 'Hello ' + ' World!';

print(y, '|', typeof(y));

print({ a = 1; b = 2; a + b; } + { 5 * 5 });
