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:
./bas2 < file
echo text | ./bas2
Try:
./try.sh
./try.sh "foo bar" "baz" "IOCCC 1998/bas2" README.md
./try.sh try.sh "bas2.c" bas2.orig.c
Judges' remarks:
Questions to ponder:
Can you determine the relationship between the input and the resulting numeric output?
The program was not designed to process files with a certain octet value, what value is that?
Hint and Extra Credit:
This entry points out a minor flaw in the IOCCC rules that has been around since 1992. It processes a certain octet value in a way that differs from a strict reading of one of the official IOCCC rules. What is the rule and what is the octet value?
Author's remarks:
The main obfuscation is the way characters are recognized, which is done by matching the bit patterns. Minor obfuscations are:
-
Useless layout.
-
Useless variable names.
-
Recursive
main()instead of 2 loops (over input characters and over bits in the character). -
?:and||instead of if statements.
