perlsub ? Perl subroutines |
SYNOPSIS |
DESCRIPTION |
Private Variables via my() |
Persistent Private Variables |
Temporary Values via local() |
Passing Symbol Table Entries (typeglobs) |
When to Still Use local() |
1. You need to give a global variable a temporary value, especially $_, 2. You need to create a local file or directory handle or a local function, 3. You want to temporarily change just one element of an array or hash |

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 that 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 |
