ylang - The language that makes you go "y?"

About

This is a language that I created on a weekend and some train rides, to explore dynamic languages and Interpreters a bit more.

I now know how JavaScript was written in 10 days.

• Is it revolutionary? No.
• Is it nice to use? Depends on your definition of nice.
• Is it stable? Not more than my mental state.
• Is it fast? Well, consider upgrading your hardware lol.
• Was it fun to make? Absolutely, I learned so much during this time!

Features

• Dynamically typed
• Turing Complete
• f is a builtin keyword
• No Syntax Sugar, no bloat
  • No semicolons, no forced line breaks
  • Often used constructs such as if or logical and are defined in the standard library
  • while a > 0 a = a - 1 is a valid expression:
    • a > 0 is the condition
    • a = a - 1 is the body
• Everything is an expression. Yes, everything.
• Some special operations include:
  • <list> * <fn> returns a new list containing all elements of the original list, applied to the given function
  • <list> / <fn> returns a new list containing all elements that return 1 when applied to the given function
  • <number> * <fn> creates a list of length <number>, where each element is the result of the call to fn(index)
  • <list> . <number> gets the element at the given index
    • Note that you can't set the element (yet?), you'd have to create a new list for that.
• Special support for intrinsics, my favorites:
  • noa(<string>) returns 1 if the argument does not contain a lowercase a (Thanks Noa!)
  • nel(<string>) returns 1 if the argument is not equal to lowercase l (Thanks Angelo!)
