rumia-quine

My simple quine programs : )

Including normal quines, Ouroboros quines and ASCII Art quines.

ASCII Art Quine

Normal ASCII Art Quine

I have implemented a simple ASCII art quine program. The ruby program ./ascii_quine/rumia_ascii.rb and ./ascii_quine/rumia_ascii2.rb are implemented using eval and lambda. It is not just an ASCII Art but also a Quine program, which means the output of this program is its own source code. You could run the script ./ascii_quine/check_output.sh to verify.

Here is the screenshot:

./ascii_quine/rumia_ascii.rb

./ascii_quine/rumia_ascii2.rb

Ouroboros ASCII Art Quine

There is an Ouroboros ASCII Quine as well. The ruby program ./ascii_quine/cirno.rb will print another ASCII Art Komeji Koishi. Then the Komeji Koishi will ASCII Art print Rumia. Finally, Rumia will print Cirno again. You could check the file cirno_result.txt to view these results.

Here are the screenshots:

You could run the script ./ascii_quine/check_output.sh to verify.

Normal Quine

I have implemented normal quine using different langages.

Normal Quines will print its own source code.

You could run the script ./normal_quine/check_output.sh to verify.

C quine

The C quine program ./normal_quine/printf.c is implemented using printf. Classic implementation :)

C++ quine

The C++ quine program ./normal_quine/str_replace.cpp is implemented using std::string::replace.

Ruby quine

1. ./normal_quine/eval.rb is implemented using eval.
2. ./normal_quine/str_format.rb is implemented using ruby string format.
3. ./normal_quine/heredoc.rb is implemented using ruby heredoc.
4. ./normal_quine/base64.rb is implemented using base64.
5. ./normal_quine/eval2.rb is implemented using eval as well, which is from ta-chibana's ASCII quine.

Ouroboros Quine

I have implemented Ouroboros quine using different langages as well.

Ouroboros Quines will print another source code written in different language, which will print another source code as well. Eventually, the original source code of first program will be printed.

C -> Python -> C

The C and Python Ouroboros quine is under folder ./ouroboros_quine/c_python/

The C program quine.c will output the python program quine.py, while the python program quine.py will output the C program quine.c. You could run the script check_output.sh to verify~

Ruby -> Python -> Ruby

The Ruby and Python Ouroboros quine is under folder ./ouroboros_quine/ruby_python/

The Ruby program quine.rb will output the python program quine.py, while the Python program quine.py will output the Ruby program quine.rb. You could run the script check_output.sh to verify~
