The commit a1c86c8a7a modified
the navigation bars to include "Original C", so all tarballs
had be update, sorry (tm Canada 🇨🇦). In particular:
The navigation bar for a winning entry now has a "_Original C_" link
(between the ✅ and the Inventory on the right hand side) so that one
may easily view the original C code that was submitted for IOCCC judging.
In addition, a number of other commits since that time
modified other winning entries.
Ran `make update` to perform the above.
To build:
make all
The author provided an unobfuscated version. See Alternate code below.
Bugs and (Mis)features:
The current status of this entry is:

To use:
./ant 'ERE' [file ...]

./try.sh
Alternate code:
The ant.alt.c is an unobfuscated version provided by the author. You can look at this code if you want some clues in how it works.

Judges' remarks:
See the author's POSIX P1003.2-like documentation file ant.txt for more information.
This program demonstrates that POSIX doesn't guarantee readability. :-)
Author's remarks:
Some of the features of my entry are:
- "Lengthy" POSIX.2 style specification and manual :) :)
- Useful subset of POSIX.2 Extended Regular Expressions.
- Recursive ERE parser/compiler that generates an NFA railroad.
- Lazy NFA to DFA evaluation to improve performance speed.
- Code tested on a variety of platforms.
- Make driven test script.
- Can be compiled with ANSI or K&R C.
- Not a toy, but actually useful and usable on systems that use DOS.
