This programming language may be used to instruct a computer to perform a task.
Frege is a purely functional programming language with non-strict semantics, strongly influenced by Haskell, but targeting the JVM, and deviates from Haskell in ways which make it easier to interoperate with Java.
Frege source files use the extension
.fr. Frege is similar enough to Haskell that
haskell-mode can be used for editing Frege source files, for example by putting this line in your
(add-to-list 'auto-mode-alist '("\\.fr$" . haskell-mode))
