emoruby

Use Emoji™

A little language that compiles Emoji down to Ruby. It's just Ruby. Really.

If I were a real language designer, I would have put a lot of thought into the syntax, semantics, and structure of emoruby. Instead I basically implemented an inefficient find-and-replace from a static dictionary. (🐄🎩!)

Anyway, here is an example hello world program:

📋 ❤️
  🔜 👋
    👀 💬😃 🌏💬
  🔚
🔚

❤️▪️🐣▪️👋

which is equivalent to this Ruby:

class Heart
  def wave
    puts "smiley earth_asia"
  end
end

Heart.new.wave

You can also define things like Procs and comments:

💭 Comment! 👋
👉 🔨
 💬😃💬
🔚▪️📞

which is equivalent to this Ruby:

# Comment! 👋
-> do
  "smiley"
end.call

You can also define Array and Hash literals, and use the {} block syntax:

◀️9️⃣➰3️⃣▶️▪️📍 ⏪ 🏂🅰🏂 🅰 ➕ 1 ⏩

Which translates to this Ruby:

[9,3].map { |a| a + 1 }

You can define private and protected methods:

📋 ❤️
  🔓 🔜 👖
    👀 💬👛💬
  🔚

  🔒️ 🔜 👕
    👀 💬💛💬
  🔚

  ⛔️ 🔜 👋
    👀 💬😃 🌏💬
  🔚
🔚

❤️▪️🐣▪️👋

which is equivalent to this Ruby:

class Heart
  public def jeans
    puts "purse"
  end

  protected def shirt
    puts "yellow_heart"
  end

  private def wave
    puts "smiley earth_asia"
  end
end

Heart.new.wave

Which will result in an exception:

NoMethodError: private method `wave' called for #<Heart:0x007f81eb840138>

Emoruby uses polyglot to enable require to be used on .emoruby files just as you do with Ruby source .rb files. To register the file extension, simply:

> require 'emoruby'
=> true
> Emoruby.register
=> nil
> require 'hello_world'
smiley earth_asia
=> true

You can run emoruby from the command line by passing an emoruby file as the first argument:

$ emoruby spec/fixtures/1_hello_world.emoruby
smiley earth_asia

The API allows both evaluation of emoruby code as well as translation to Ruby.

> source = "💬😃 🌏💬"
=> "💬😃 🌏💬"
> Emoruby.eval(source)
=> "smiley earth_asia"
Emoruby.emoji_to_ruby(source)
=> "\"smiley earth_asia\""

The Emoruby team embraces and advocates the adoption of the the emerging emotional versioning standard ("emover" for short).

The initial release was 💩 (in honor of @tenderlove's 💩-lang). After that, ✊ was released. Then came 🐷. The next planned release is 📈.
