This is a new package that allows the user to compare a string against a set of strings and execute an action if it doesn't match said set.

ifallfalse – Compare a string against a set of other strings

This package allows you to check whether a string is contained within another set of strings, and perform an action if it is not. This is done by using the allfalse environment and passing in a string and an action to be performed if the string is not contained in the set. Then, passing in a string to the \orcheck macro inside the respective allfalse environment adds that to the set of strings.

This package does not work with the Lua engine.
