A revolutionary programming language that combines Css and Assembler to write modern web apps.

To test it out head over to the playground!

Features

• strings (kinda), are a first class citizen
• numbers, only floating point. Integers are not supported. They're useless anyway, we're not working on a 16bit platform here.

Concepts

• strings, denoted by quotes: "example"
• numbers, just write 'em: 1234
• symbols, prefixed with a pound sign: #document
• registers, prefixed with a dollar sign: $foo
  The special discard register $ with no name.
  The special $argN register, for example: $arg0
  The special $this register

Examples

• counter-button
• doodle
• p2pchat
• simple-onclick

Example code

body {
  @onload: [
    lea $alert, #alert

    psh "hello world!"
    jsr $, $alert, 1
  ];
}
