Concepts of Cotowali

Outputs shell script that is fully compliant with POSIX standards.
Simple syntax.
Simple static type system.
Syntax for shell specific feature like pipe and redirection.

Example

fn fib(n: int): int {
  if n < 2 {
    return n
  }
  return fib(n - 1) + fib(n - 2)
}

fn int |> twice() |> int {
   var n = 0
   read(&n)
   return n * 2
}

assert(fib(6) == 8)
assert((fib(6) |> twice()) == 16)

fn ...int |> sum() |> int {
  var v: int
  var res = 0
  while read(&v) {
    res += v
  }
  return res
}

fn ...int |> twice_each() |> ...int {
  var n: int
  while read(&n) {
    yield n * 2
  }
}

assert((seq(3) |> sum()) == 6)
assert((seq(3) |> twice_each() |> sum()) == 12)

// Call command by `@command` syntax with pipeline operator
assert(((1, 2) |> @awk('{print $1 + $2}')) == '3')
