Piko

Esolang created for the Twist YSWS program.

Features

The grammar is limited to one character:

• "f": Function
• "c": Call Function
• "l": Loop
• "b": Break
• "r": Return
• "o": Output
• "i": Input
• "a": Assign

Operators

Comparison and arithmetic operators are available. However, there are no numbers allowed in literals. Or capital letters. Or any other symbols. Just a-z. If you try to perform comparison or arithmetic, the two strings you pass are interpreted as bijective base-26 numbers. The operations you perform are done on the base-26 representation of the string.

Chaining

Some operations can be chained.

• Assign Output (ao) assigns a value to a variable then also output's that value.
• Input Output (io) takes in a value and immediately calls output on it.

Building

There are two projects in this repository, a web REPL to test Piko and the library itself.

cargo build --workspace

Test

You can try it out here. Might not be available forever, though.
