You’ll need to have Ruby installed to run all the automated check
Look at jpeg.jpg in an image viewer program.
This is a program which, when fed its own source, generates a program that almost is its whitespace inverse, which, in its order, generates a JPEG file (speaking of file size abuse, that is about 16.4 times larger than a PBM file with the same image, but the source was also abusing the size counting program…)
Don’t pay attention to the OCR
behind the ruby curtain — it’s a straightforward bitmap comparison.
I picked JPEG instead of PNG, GIF, or BMP
because it is the most difficult to generate.
I believe that the JPEG encoder is the world’s smallest ever.
Nevertheless, the program was too big to meet the IOCCC’s size rule.
So I created a smaller bootstrap program that generates the main program.
prog.c contains fragments of the main program as a comment
iocccsize -i does not count.
I gratefully think the judges for spoiling the size rule this year.
I think the program will work on any major platforms and compilers.
