A modular Clojure/ClojureScript library all about the 4-valued logic of cognition first introduced 2017 by Ralf Peyn in uFORM iFORM. In its core, the purpose of the library is to enable the representation, evaluation and algebraic simplification of all (undetermined, imaginary, unclear, …) FORMs that have been introduced in the book.
Note: FORM tricorder and FORM plotter still use the legacy JS-version of formform and are currently being re-designed and re-developed. In the meantime, feel free to use the old versions, they will work just fine.
