The unobfuscated version was recently provided by the author so this is no longer an issue. A code block in the INABIAF was changed to a quote as it's not code but something the author wrote. This entry's index.html might not be done as a question also has to be addressed before the manifest can be fixed.

The current status of this entry is:
|
|
|
|
> **STATUS: INABIAF - please DO NOT fix**
|
|
|
|
For more detailed information see [1993/ant in bugs.html](../../bugs.html#1993_ant).
|
|
|
|
|
|
## To use:
|
|
|
|
``` <!---sh-->
|
|
./ant 'ERE' [file ...]
|
|
```
|
|
|
|
|
|
## Try:
|
|
|
|
``` <!---sh-->
|
|
./try.sh
|
|
```
|
|
|
|
|
|
## Alternate code:
|
|
|
|
The [ant.alt.c](%%REPO_URL%%/1993/ant/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:
|
|
|
|
|
|
``` <!---sh-->
|
|
make alt
|
|
```
|
|
|
|
|
|
### Alternate use:
|
|
|
|
Use `ant.alt` like you would `ant` above.
|
|
|
|
|
|
### Alternate try:
|
|
|
|
``` <!---sh-->
|
|
./try.alt.sh
|
|
```

## Judges' remarks:
|
|
|
|
See the author's POSIX P1003.2-like documentation file [ant.txt](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.
|
|
- See also [ant.txt](ant.txt).
