Prepare for the winners of **IOCCC28**. > However these are not the 2024 droids you are looking for. :-) The HTML menu (both JavaScript and non-JavaScript) has been updated. The `Status -> Rules and guidelines' have been replaced with two separate menus `Status -> IOCCC rules` and `Status -> IOCCC guidelines`. Added a new top level `social.html` page: built from a new `social.md`. Sorted rules for building specific web pages in the top level `Makefile`. Added `make social` to make the `social.html` page from `social.md`. The `bin/gen-top-html.sh` now is able to process a argument of **social** to process the new top level `social.html` page. Changed `bin/gen-top-html.sh` VERSION from "2.0.0 2025-03-13" to "2.0.1 2025-07-25". Below `About -> Home page` a new `About -> IOCCC social media` menu item as added. Because the menu change touched every HTML file, we changed the general copyright date range for HTML files from "1984-2024" to "1984-2025" due to the extensive changes made for **IOCCC28**. Those markdown files that were modified in 2025 had their copyright date range also changed from "1984-2024" to "1984-2025". Rebuilt tarballs and sitemap due to the extensive HTML rebuilding. Ran `make update` to perform the above.
To build:
make chaos
NOTE: Some systems do not implement halfdelay() in their libcurses.
You might try compiling with -lncurses if you have that library.
Or you can build this entry without the halfdelay() call by:
make chaos_nohalf
Bugs and (Mis)features:
The current status of this entry is:
STATUS: INABIAF - please DO NOT fix
For more detailed information see 1998/chaos in bugs.html.
To use:
./chaos
Try:
./try.sh
This script will run the program on each data file. To quit the program hit q.
If not all files have been used it will go to the next one; otherwise the script
will be finished. To end the script early send intr/ctrl-c.
The script will give you instructions on how to use the program and things to try each time it is run, as a helpful reminder.
Judge's Comments:
This is the author's first IOCCC entry. We thought the entry was a nice example of a compact collection of obfuscations.
Can you figure out why, in some cases, it wants to read itself?
Author's remarks:
Usage
The executable takes a single argument for the data file to use. If no argument is given, it will find a data file by itself, don't worry about it...
Summary
This is a simple ncurses 3D object viewer. The keys y, u, i,
h, j, and k rotate. a and z zoom in and out. q quits.
Given about 3 seconds of no input, it will start rotating until
interrupted by user input.
Features (aka Bugs):
Memory malloc(3)ed is never freed. This shouldn't be a big deal,
since only one block is ever allocated, and the OS should recover it.
My local flavor of lint doesn't seem to like the fact that I never
return from main(). Feh, what does it know? Otherwise, ignoring
lint's over protectiveness ("Of course I'm not using all of the
functions defined in curses.h!"), it's lint clean.
If the compiler happens to generate the byte sequence "AlWuzEre" in the executable by chance, the program may be unable to locate the embedded string. As a result, running the program without an external data file may act in undefined ways.
If the compiler doesn't store char * P's data in a nice contiguous
stream, it would be bad. As above, it would break running the
program without an external data file.
If the incoming data is corrupt, the results are undefined. (Although dumping core is a popular result.)
When a point passes behind the camera, it is still plotted. The object will "bounce" off the camera, but the result (some points in front, some reflected from the rear) looks really odd. And it sometimes hangs. So just don't fly through objects. You'll be happier.
