A ruby based interpreter for derplang. https://esolangs.org/wiki/Derplang
derp-rb fully supports all the built-in commands for derplang as defined here alongside a few of its own.
These are the new commands under derp-rb
unset allows you to unset the value of a variable. For example
va:x:10:ou:x:un:x:
Would set the value of x to 10, print it and then unset its value. attempting to use the variable again would raise an error.
in works similar to ip but with the added functionality of allowing to set a prompt.
ip:number:x:
Would produce
number:
and allow you to take user input.
As an added feature, the END label is added, which when used will take you to the end of the program and ending execution.
This project was heavily inspired by derpi
