Module Version: 1.04   Source   Latest Release: Module-Versions-Report-1.06

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.
