This module implements a rudimentary shell script parser in Perl.

The Shell::Source allows arbitrary shell scripts, or other programs for that matter, to be run and their environment to be inherited into a Perl program.

Smart comments provide an easy way to insert debugging and tracking code into a program. They can report the value of a variable, track the progress of a loop, and verify that particular assertions are true. Best of all, when you're finished debugging, you don't have to remove them. Simply commenting out the use Smart::Comments line turns them back into regular comments. Leaving smart comments in your code is smart because if you needed them once, you'll almost certainly need them again later.

Sort::Key provides a set of functions to sort object arrays by some (calculated) key value.

This module has two main goals: to make it easy to create correct sort functions, and to make it simple to select the optimum sorting algorithm for the number of items to be sorted. Sort::Maker generates complete sort subroutines in one of four styles, plain, orcish manouver, Schwartzian Transform and the Guttman-Rosler Transform. You can also get the source for a sort sub you create via the sorter_source call.

Sort::Tree implements a mechanism for sorting a list of objects into a tree structure and flattening it back into a list. Among other things, this is useful for displaying database queries in hierarchical views, such as nested categories, parent-child relationships, threaded discussions, and so forth. Trees have a lot to do with Graph theory, so if this module doesn't suit your fancy, have a look at the Graph:: Perl modules for an academically oriented implementation that employs vertex, edge, and node operations. For more information on how to use the perl module, see the pod documentation via the command perldoc Sort::Tree or, after installation, view the man pages with man Sort::Tree

Sort::Versions allows easy sorting of mixed non-numeric and numeric strings, like the "version numbers" that many shared library systems and revision control packages use. This is quite useful if you are trying to deal with shared libraries. It can also be applied to applications that intersperse variable-width numeric fields within text. Other applications can undoubtedly be found. For an explanation of the algorithm, it's simplest to look at these examples: 1.1 < 1.2 1.1a < 1.2 1.1 < 1.1.1 1.1 < 1.1a 1.1.a < 1.1a 1 < a a < b 1 < 2 1 < 0002 1.5 < 1.06

Spiffy is a framework and methodology for doing object oriented programming in Perl. Spiffy combines the best parts of Exporter.pm, base.pm, mixin.pm and SUPER.pm into one magic foundation class. It attempts to fix all the nits and warts of traditional Perl OO, in a clean, straightforward and (perhaps someday) standard way.

The Storable package brings you persistency for your perl data structures containing SCALAR, ARRAY, HASH or REF objects, i.e. anything that can be conveniently stored to disk and retrieved at a later time. It can be used in the regular procedural way by calling store with a reference to the object to store, and providing a file name. The routine returns undef for I/O problems or other internal error, a true value otherwise. Serious errors are propagated as a die exception. To retrieve data stored to disk, you use retrieve with a file name, and the objects stored into that file are recreated into memory for you, and a reference to the root object is returned. In case an I/O error occurred while reading, undef is returned instead. Other serious errors are propagated via die.

Stream::Buffered is a buffer class to store arbitrary length of byte strings and then get a seekable filehandle once everything is buffered. It uses PerlIO and/or temporary file to save the buffer depending on the length of the size.
