BrainFuck Beautifier

Usage

bfb pattern bf
bfb pattern < bf

Maps a Brainfuck program into a pattern file.

Rules

• Characters except for +-.,<>[] in the bf file are ignored
• Only # characters (configurable) in the pattern file are replaced
• Excess bf characters are dumped at the bottom so the program still runs
• Excess # characters are replaced with + and - randomly, which hopefully won't break your program (configurable)

Example

demo.pat:

I N T R O D U C I N G

#         ### #
#        #    #
#        #    #
#####  ###### #####

#    #   #    #    #
