Module::Versions::Report(3pm)				User Contributed Perl Documentation			     Module::Versions::Report(3pm)

NAME
Module::Versions::Report -- report versions of all modules in memory SYNOPSIS
use Module::Versions::Report; ...and any code you want... This will run all your code normally, but then as the Perl interpreter is about to exit, it will print something like: Perl v5.6.1 under MSWin32. Modules in memory: attributes; AutoLoader v5.58; Carp; Config; DynaLoader v1.04; Exporter v5.562; Module::Versions::Report v1.01; HTML::Entities v1.22; HTML::HeadParser v2.15; HTML::Parser v3.25; [... and whatever other modules were loaded that session...] Consider its use from the command line: % perl -MModule::Versions::Report -MLWP -e 1 Perl v5.6.1 under MSWin32. Modules in memory: attributes; AutoLoader v5.58; [...] DESCRIPTION
I often get email from someone reporting a bug in a module I've written. I email back, asking what version of the module it is, what version of Perl on what OS, and sometimes what version of some relevent third library (like XML::Parser). They reply, saying "Perl 5". I say "I need the exact version, as reported by "perl -v"". They tell me. And I say "I, uh, also asked about the version of my module and XML::Parser [or whatever]". They say "Oh yeah. It's 2.27". "Is that my module or XML::Parser?" "XML::Parser." "OK, and what about my module's version?" "Ohyeah. That's 3.11." By this time, days have passed, and what should have been a simple operation -- reporting the version of Perl and relevent modules, has been needlessly complicated. This module is for simplifying that task. If you add "use Module::Versions::Report;" to a program (especially handy if your program is one that demonstrates a bug in some module), then when the program has finished running, you well get a report detailing the all modules in memory, and noting the version of each (for modules that defined a $VERSION, at least). USING
Importing If this package is imported then END block is set, and report printed to stdout on a program exit, so use "use Module::Versions::Report;" if you need a report on exit or "use Module::Versions::Report ();" otherwise and call report or print_report functions yourself. report and print_report functions The first one returns preformatted report as a string, the latter outputs a report to stdout.
