Umi

Note that the .expected files are the expected output of the corresponding .umi files.

Example

Int !(Int n, Void _) {
    if n == 0 { 1 }
    else { n * (n - 1)! }
}

Void main() {
    print(0!)  #         1
    print(1!)  #         1
    print(5!)  #       120
    print(10!) #   3628800
    print(12!) # 479001600
}

Goals

• Compiles to CIL
• Turing Complete
• Self-hosted
• Published on the AUR
• Pong
• VSCode extension with auto-complete, etc
• Interoperability with C# (can use any C# file in Umi file but have to manually make bindings)

Features

• Strong static typing
• Implicit and explicit return
• Function overloading
• if and else statements
• while loops
• Aliases
• Classes
  • All methods are virtual by default
  • Inheritance
• Generics
• Immutability by default
  • Immutable references like final in Java
  • Make variables mutable with mut keyword
• Including other umi files (importing)
• Creating range array with ...
  • E.g. 0...10

Planned

• Macros or inline functions
• for in loop
• String interpolation
• Anonymous functions
• Switch cases
