ABC Path Generator is a program and a Perl library that generates layouts of ABC Path based on the input of a random number generator. Giving different seeds to the generator will yield different layouts. ABC Path is a puzzle game in which one should position the letters from "A" to "Y" in a 5*5 grid based on clues. It is featured on brainbashers.com. ABC Path Generator makes use of depth-first-search to find usable final paths, and then assigns the clues for it, also using DFS.
AI::Prolog is a predicate logic engine implemented in pure Perl. In predicate logic, instead of telling the computer how to do something, you tell the computer what something is and let it figure out how to do it. Conceptually, this is similar to regular expressions. The AI::Prolog distribution contains a Prolog shell called aiprolog and two short adventure games, spider.pro and sleepy.pro.
C-DynaLib is a Perl module that allows Perl programs to call C functions in dynamic libraries. It is useful for testing library functions, writing simple programs without the bother of XS, and generating C function pointers that call Perl code. If you have a C compiler that Perl supports, you will get better results by writing XSubs than by using this module.
CHI provides a unified caching API for Perl, designed to assist a developer in persisting data for a specified period of time. The CHI interface is implemented by driver classes that support fetching, storing, and clearing of data. Driver classes exist or will exist for the gamut of storage backends available to Perl, such as memory, plain files, memory mapped files, memcached, and DBI. CHI is intended as an evolution of DeWitt Clinton's Cache::Cache package, adhering to the basic Cache API but adding new features and addressing limitations in the Cache::Cache implementation.
