An interpreter for the BLooP and FLooP programming languages.
bfloop is an interpreter for the BLooP and FLooP programming languages described in the book Gödel, Escher, Bach by Douglas Hofstadter.
BLooP is a language that has only bounded loops, in other words before you enter a loop you have to give a fixed upper limit on the number of times to run the body, and you can’t change the limit while in the loop. It is impossible for a BLooP program to run forever; it always quits with an output in some finite time, an upper limit for which is predictable in advance. Functions that BLooP can compute are called primitive recursive functions, and it turns out that not all functions are primitive recursive. The FLooP language is the same as BLooP with the addition of an unbounded loop (MU-LOOP). FLooP can calculate anything your computer can calculate, but you cannot say in general whether a FLooP program will eventually terminate.
