Emerald Programming Language

Emerald is an object oriented language that uses prototypal based inheritance.

Installation

git clone https://github.com/emeraldlang/emerald.git
cd emerald
mkdir build
cd build
conan install ..
cmake ..
make

Compiling

The compile command will compile the specified source files and creates an .emc file.

./build/bin/emerald compile some_folder/some_file.em

Running

The run command takes the name of the module you want to execute. It looks for a .emc file so be sure to run the compile command before.

./build/bin/emerald run some_folder.some_file

A Few Simple Examples

Hello World

import core

core.print('hello world')

Fibonacci

def fib : n
  return additive_sequence(n, 0, 1)
end

def additive_sequence : n, t0, t1
  if (n == 0) return t0
  if (n == 1) return t1
  return additive_sequence(n - 1, t1, t0 + t1)
end

Collatz Sequence

def collatz : n
  let c = 1
  while (n != 1) do
    if (n % 2 == 0) then
      n = n / 2
    else
      n = 3 * n + 1
    end
    c += 1
  end
  return c
end

Inheritance

let foo = {
  name: 'foo',
  one: 1,
  two: 2
}

let bar = clone foo
bar.two = 'two'
bar.three = 3

bar.one # 1
bar.three # 3
bar.two # 'two'
bar.name # 'foo'
foo.name # 'foo'
