The `display_as` field in an `.entry_json` file must match the regex `^[a-z][0-9a-z]*$` now. This is needed to reduce errors during the final round while converting a potential submission to entry form. Modify `1992/buzzard.2/.entry.json` and `1993/rince/.entry.json` to change `display_as` field to use lower case. Correct `2012/omoikane/.entry.json` to correctly reflect changes made by commit2955e5d07eand commit2955e5d07e. Change `bin/cvt-submission.sh` to verify that the `display_as` matches the above regex. Changed `bin/cvt-submission.sh` VERSION from "2.2.2 2025-06-30" to "2.3.0 2025-07-02". Rebuild all tarballs, both at the entry and the year level due recent changes to `var.mk`, `1337.mk`, and `ioccc.css`. Rebuild sitemap due to the changes above. Ran `make update` to test and perform the above.
To build:
make all

Bugs and (Mis)features:
The current status of this entry is:
STATUS: INABIAF - please DO NOT fix
For more detailed information see 1993/ant in bugs.html.
To use:
./ant 'ERE' [file ...]
Try:
./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.
Alternate build:
If you wish to build this deobfuscated version, you can do so like:
make alt
Alternate use:
Use ant.alt like you would ant above.
Alternate try:
./try.alt.sh
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.
