===Version 1===
An implementation of a [[Brainf***]] interpreter in [[Ruby]].
More effort could be made to read a program from a file or from stdin.
<
def initialize(program)
@d = [0] * 30_000
Line 76:
# use nested loop to increment count to 64 and print (should be '@')
# followed by a newline
RCBF.new('>>++++[<++++[<++++>-]>-]<<.[-]++++++++++.').run</
{{out}}
Line 82:
@</pre>
===Version 2===
This variant converts the brainfuck into Ruby code and runs that instead.
Do note that this requires Ruby1.9.1 or later, earlier versions need a somewhat more verbose variant.
Line 88:
BF code may be read from a file or taken from STDIN.

'.' => 'putc(m[p]&=255);',
',' => 'm[p]=STDIN.getc.ord if !STDIN.eof;')</syntaxhighlight>
