Debugger never leave loops? about befunge-93 HOT 1 CLOSED

Thanks for the report. I believe the problem is that, by default in debug mode, input and output don't do anything at all - meaning the , leaves the character E on the stack. (and then this test program loops forever because _ never pops a 0.)

I think this is discussed somewhere in #14 and is considered undesirable behaviour of the debugger and it should probably get fixed one day.

In the meantime, there's a simple workaround: use the -w option to send the output somewhere when using the debugger. (Similarly, use -r if the program takes input). For example, I ran your test program with

bef -d -r output.txt test.bf

and the program did terminate correctly.

EDIT: originally I wrote -o and -i for the options to use; they are actually called -w and -r.
