Furry PawsVersion of implementation Furry Paws of programming language FP
This one probably has only one version.
~x is constant-value function (denoted with
% in Interactive FP).
emit is a function which writes its argument to stdout.
main is a function which is the first to be invoked when the program is executed.
main = emit.(return ~"Hello, World!\n")
This example works in exactly the same way as the one in Interactive FP, except for that it doesn’t define
zero function, since it’s built-in. Note that here all operations are done within integer data type, and 13! overflows it, so the program can be called only to print factorials up to 12!.
show is another way to output data.
dec = sub.[id, ~1] seq = zero -> [id] ; cat.[seq.dec, [id]] factorial = zero -> ~1 ; mul.[id, factorial.dec] main = show.(return @factorial.(seq.~12))
This example works exactly like the one for Interactive FP.
one = eq.[id, ~1] dec = sub.[id, ~1] seq = one -> [~1] ; cat.[seq.dec, [id]] fibonacci = lt.[id, ~3] -> ~1 ; add.[fibonacci.sub.[id, ~1], fibonacci.sub.[id, ~2]] main = show.(return @fibonacci.(seq.~16))
