User:Yayimhere/Primelist language

Primelist(working title) is an esolang created by User:Yayimhere based on prime factors.

Lists

Lists are written like:

[a, b, c, d,...]

the elements may be numbers or other lists. Number operations act upon the sublists independently. Technically, each number is a singleton list [x].

Operations

• µf: applies the function f to each element in its input.
• p: replaces each element in its input with their unique prime factors, going from lowest to highest.
• `fx: apply f to x.
• +: increment the first element of the list.
• *: take the first element of the list and call it x. Multiple the next x elements of the list together.
• {x -> y}: iff the elements of the input are all somewhere in x, return y, else return the input.
• [f | g]: takes an input x. iff `fx = x return `[f | g]`gx else return `gx.
• #t: identity function.
• #f: `{#f -> y}x = y, always.
• ;: prepend the first input to the second.
