Roo

Roo is a imperitive programming language that takes concepts from functional programming. Its central goal is to avoid the kitchen-sink-esque hodgepodge of languages like C++, instead expressing logic through fewer, more powerful features.

Aims

• No separation of definition and implementation (no headers)
• Easier build process - nice source and dependency management
• Safety - strong type-checking and powerful expression of programmer intent
• Terse, expressive syntax - no extranious punctuation

It looks something like this:

#[Name(example)]

import Prelude

type color
{
  r : float
  g : float
  b : float
  a : float
}

fn PrintColor(color : color&)
{
  PrintFmt("Color: ({}, {}, {}, {})\n", color.r, color.g, color.b, color.a)
}

#[Entry]
fn Main() -> int
{
  #[Debug]
  Print("Hello, World!\n")

  // Make and print a color
  myColor : color{1.0f, 0.0f, 1.0f, 1.0f}
  PrintColor(myColor)

  return 0
}

Using the compiler

• At the moment, The compiler can only produce executables usable on x86_64, System-V, ELF-compatible systems
• (Temporary step) Run make prelude to build Prelude (our standard library)
• Run ./roo to compile and link all the files in the current directory
• Various DOT files will also be produced, which may be converted to PNG with dot -Tpng -o {file}.png {file}.dot
