A fun, friendly, statically-typed programming language.

a work-in-progress... (this readme will be updated if/when it's ready for people to try out)

to run while developing: ./bin/run run ./bin/run build path/to/main.pa

to test: ./bin/test

to build in release mode: ./bin/build_release

examples

The syntax shown here may not be supported yet, or it may be slightly out of date, but these examples should give you an idea of what the language looks like:

let name = "Reid"
let str = "hello " ++ name ++ "!"

str
  | replace "hello" with "what's up"
  | replace "!" with "?"
  | uppercase
  | then (print _)

struct person (
  name :: string
  age :: int
)

def _ | greeting :: person -> string {
  p => "hi there, " ++ p.name
}

let p = person ("Reid", 27)

print (person | greeting)

enum color { red, green, blue }

def random-color _ :: () -> color {
  random-int-between 1 and 3 | match {
    case 1 => red
    case 2 => green
    case 3 => blue
  }
}

let c = random-color ()

c | match {
  case red => print "it's red!"
  case green => print "it's green!"
  case blue => print "it's blue!"
  case _ => print "???"
}
