App::Trace provides debug/tracing support for perl programs and modules. The basic concept is that you put a special call at the beginning and end of each subroutine/method, and when tracing is enabled, you can see the flow of your program.

A Heap implementation for Perl using functions that are loosely modeled after the C++ STL's binary heap functions. They all take an array as argument, just like perl's built-in functions "push", "pop" etc. The implementation itself is in C for maximum speed.

Friendlier flags for B By default, "$foo->flags" when passed an object in the "B" class will produce a relatively meaningless number, which one would need to grovel through the Perl source code in order to do anything useful with. This module adds "flagspv" to the SV and op classes and "privatepv" to the op classes, which makes them easier to understand.

B::Hooks::OP::Annotation provides a way for XS code that hijacks OP op_ppaddr functions to delegate to (or restore) the previous functions, whether assigned by perl or by another module. Typically this should be used in conjunction with B::Hooks::OP::Check.

This module is a layer between the perl-internals-examining parts of Malcolm Beattie's perl compiler (the B::* classes) and your favorite graph layout tool (currently Dot and VGC are supported, but adding others would be easy). It examines the internal structures that perl builds to represent your code (OPs and SVs), and generates specifications for multicolored boxes and arrows to represent them.

B::Keywords supplies seven arrays of keywords: @Scalars, @Arrays, @Hashes, @Filehandles, @Symbols, @Functions and @Barewords. The @Symbols array includes the contents of each of @Scalars, @Arrays, @Hashes and @Filehandles. Similarly, @Barewords adds a few non-function keywords (like __DATA__, NULL) to the @Functions array. All additions and modifications are welcome.

Bread::Board is an inversion of control framework with a focus on dependency injection and lifecycle management. It's goal is to help you write more decoupled objects and components by removing the need for you to manually wire those objects/components together.

This module was mainly written for Net::XMPP2, Net::IRC3 and BS to provide a consistent API for registering and emitting events. Even though I originally wrote it for those modules I released it separately in case anyone may find this module useful.

The functions in this module implement or assist the writing of programs, or parts of them, in Continuation Passing Style (CPS). Briefly, CPS is a style of writing code where the normal call/return mechanism is replaced by explicit "continuations", values passed in to functions which they should invoke, to implement return behaviour.

The Perl Cache package provides Cache::Cache, a generic interface for creating persistent data stores. This interface is implemented by the Cache::MemoryCache, Cache::SharedMemoryCache, Cache::FileCache, Cache::SizeAwareFileCache, Cache::SizeAwareMemoryCache, and Cache::SizeAwareSharedMemoryCache classes. This work replaces File::Cache and IPC::Cache. -Anton <tobez@FreeBSD.org>
