Quine Tools Copyright 2011 Mikiya Okuno License GPLv3

This package includes the following programs.

• jbanner.rb ... A simple command to generate a banner written in Japanese.
• quine-gen.rb ... A simple command to generate a Quine from a banner.

=========== BASIC USAGE

shell> jbanner.rb -f "path_to_font.bdf" ここに テキストを 書いて ください | quine-gen.rb -s 2 | ruby | ruby

You should pass the output to ruby twice in order to ensure that the output is really a quine. If the banner is too short, the ruby program will fail with a Syntax error. You can workaround a problem by increasing the scale factor.

============ CYCLIC QUINE

This toolkit can generate cyclic quine, which produces B by executing by A, produces C by executing B, D, E and so forth, then back to A again.

shell> jbanner.rb -f "path_to_font.bdf" -s === 渋谷 === 新宿 === 池袋| quine-gen.rb -x 4 -y 2 -p === > stations.rb

shell> ruby stations.rb # 渋谷 shell> ruby stations.rb | ruby # 新宿 shell> ruby stations.rb | ruby | ruby # 池袋 shell> ruby stations.rb | ruby | ruby | ruby # 渋谷 again
