Module::Versions::RepoUser)Contributed Perl DocumenModule::Versions::Report(3)NAMEModule::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.
