Golunar

Golunar is a derivative of Unary, which is itself a derivative of Brainfuck. It is thus even further removed from usability. Golunar was derived by Peter Berg in 2013. The name is a mix of "Unary" and "logarithm."

Translator
The following shell script can be used to convert from brainfuck to Golunar. For best results, it should be run as BC_LINE_LENGTH=0 sh bf2gl.sh FILE.

bf='><+\-.,[]' echo "ibase=2; 1`cat $1 | tr -cd $bf | tr $bf '\0-\7' | xxd -b -c1 | cut -d\ -f2 | sed s/00000// | paste -sd '\0'`" | bc
