Changed the model of `status.json` model.
Updated `status.json` IOCCC_status_version from "0.2 2023-05-22"
to "1.0 2024-03-09".
Updated FAQ 2.6, improving how IOCCC entries announced.
Moved `bin/ioccc-status.sh` to `tmp/ioccc-status.sh`
now that we have a new status.json model for
which this tool no longer fits (sorry tm Canada 🇨🇦).
Added `status.md` markdown to explain the `status.json` model.
Added `status.html` to both display the contents of `status.json`
and render the contents of `status.md` as HTML.
Added `bin/status2html.sh` to convert `status.json`
into HTML for the `status.html` file.
Added `bin/gen-status.sh` to form `status.json`
and `status.html` files.
Added `make gen_status` to top level Makefile.
Performed `make www` to complete all of the above.
To build:
make all
To use:
echo foo bar | ./dg
Try:
./try.sh
Judges' remarks:
Some C preprocessors got confused about single quotes in certain cases. In particular, the following source line:
b12(ase(bco(acp(bi(acp(bcp(acp(bpl(aqu(bqu(A))))))))))))))))))))))))))))))
sometimes has to be changed to:
b12(ase(bco(acp(bi(acp(bcp(acp(bpl('A'))))))))))))))))))))))))))))
particularly if the C preprocessor botches single quotes in cpp expansions, which we have done for the wider audience.
Author's remarks:
If my preprocessor could hack it, I could write this as one single line rather than 4, but when I do that I get a complaint "defines nested too deeply".
Obfuscation spoiler:
This is another rot13 job (believe it or not) - the #defines are a
novel way of adding tokens: #define b12(x) 12 x means that at
some point in the source a 12 is followed by the compressed nested
#defines. The b12 gets the previous compression as an argument, and
prepends the 12, thus making another step in the recreation of the
source. The axx() #defines do the same, but add tokens after.
As for the rot13 algorithm, it relies on index(3) to find if the
character is in the set A-Za-z. l[] is an array that gets filled
with:
"nopqrstuvwxyzzzzabcdefghijklmmmmNOPQRSTUVWXYZZZZABCDEFGHIJKLMMMM"
If index(3) says the char is in the alphabet, then XOR the offset
with 16 to translate, and output, otherwise pass it unchanged.
