Modules: Creation, Use, and Abuse

Guidelines for Module Creation

Do similar modules already exist in some form?, Try to design the new module to be easy to extend and reuse, Some simple style guidelines, Select what to export, Select a name for the module, Have you got it right?, README and other Additional Files, A description of the module/package/extension etc, A copyright notice - see below, Prerequisites - what else you may need to have, How to build it - possible changes to Makefile.PL etc, How to install it, Recent changes in this release, especially incompatibilities, Changes / enhancements you plan to make in the future, Adding a Copyright Notice, Give the module a version/issue/release number, How to release and distribute a module, Take care when changing a released module

Guidelines for Converting Perl 4 Library Scripts into Modules

There is no requirement to convert anything, Consider the implications, Make the most of the opportunity, The pl2pm utility will get you started, Adds the standard Module prologue lines, Converts package specifiers from ' to ::, Converts die(...) to croak(...), Several other minor changes

Guidelines for Reusing Application Code

Complete applications rarely belong in the Perl Module Library, Many applications contain some perl code which could be reused, Break-out the reusable code into one or more separate module files, Take the opportunity to reconsider and redesign the interfaces, In some cases the 'application' can then be reduced to a small

FLAG VALUES

G_SCALAR

G_ARRAY

G_DISCARD

G_NOARGS

G_EVAL

G_KEEPERR

Determining the Context

KNOWN PROBLEMS

EXAMPLES

No Parameters, Nothing returned

Passing Parameters

Returning a Scalar

Returning a list of values

Returning a list in a scalar context

Returning Data from Perl via the parameter list

Using G_EVAL

Using G_KEEPERR

Using perl_call_sv

Using perl_call_argv

Using perl_call_method

Using GIMME

Using Perl to dispose of temporaries

Strategies for storing Callback Context Information

1. Ignore the problem - Allow only 1 callback, 2. Create a sequence of callbacks - hard wired limit, 3. Use a parameter to map to the Perl callback
