2005/klausler - Abuse of the rules

Anagram generator

Author:

To build:

    make

To use:

    ./klausler arg1 arg2 | head

Try:

    ./try.sh

Judges’ remarks:

To reduce the size of the source, include other people’s data. That is what Peter suggests when he describes how to generate a critical header file.

In other words: make use of other words! :-)

Rules might have to be changed!

Author’s remarks:

A useful tool to help one appear extra smart and witty when IRCing, or even to just be highly annoying.

Finds best anagrams for word or phrase given as program arguments. Use only lower-case letters in these arguments. Output is sorted firstly in ascending order of word count (fewer words are better) and secondly in descending order of word length. Pipe the output into more(1)/less(1)/head(1) and you’re likely to find the most amusing possibilities in the first few screenfuls of output. For example, ./klausler fawlty towers | more quickly prints “waterfowl sty”. The fewer obscure short words in your system’s dictionary, the better the quality of the output; indeed, all one-letter words apart from a, i, and s (for plurals) are ignored when the dictionary is constructed by make dict.h.

Some history and explanation: When I noticed the call for entries in this year’s IOCCC, I submitted two of them. I worked on the first one very hard to obfuscate it beautifully, using a goofy algorithm, wonderful two’s-complement arithmetic tricks, and cute formatting. It was a glorious work so lovely as to make even strong men weep in admiration… but it didn’t win anything. On the other hand, this crappy little other program, which was only mildly obfuscated from its original hacked form, took home an award!

I’m embarrassed to admit that I don’t even know which specific rule this entry has abused. It’s just yet another anagram generator and it was written very late one night. And now I honestly do not know how it works, so please don’t ask. Upon reviewing the program after its unexpected honor, I guess that it’s remarkable only for its complete lack of macros, sneaky naming, main() recursion, or other tricks. Enjoy!
