NAME

6       Module::Versions::Report -- report versions of all modules in memory
7

SYNOPSIS

9         use Module::Versions::Report;
10
11         ...and any code you want...
12
13       This will run all your code normally, but then as the Perl interpreter
14       is about to exit, it will print something like:
15
16         Perl v5.6.1 under MSWin32.
17          Modules in memory:
18           attributes;
19           AutoLoader v5.58;
20           Carp;
21           Config;
22           DynaLoader v1.04;
23           Exporter v5.562;
24           Module::Versions::Report v1.01;
25           HTML::Entities v1.22;
26           HTML::HeadParser v2.15;
27           HTML::Parser v3.25;
28           [... and whatever other modules were loaded that session...]
29
30       Consider its use from the command line:
31
32         % perl -MModule::Versions::Report -MLWP -e 1
33
34         Perl v5.6.1 under MSWin32.
35          Modules in memory:
36           attributes;
37           AutoLoader v5.58;
38           [...]

DESCRIPTION

41       I often get email from someone reporting a bug in a module I've writ‐
42       ten.  I email back, asking what version of the module it is, what ver‐
43       sion of Perl on what OS, and sometimes what version of some relevent
44       third library (like XML::Parser).  They reply, saying "Perl 5".  I say
45       "I need the exact version, as reported by "perl -v"".  They tell me.
46       And I say "I, uh, also asked about the version of my module and
47       XML::Parser [or whatever]".  They say "Oh yeah.  It's 2.27".  "Is that
48       my module or XML::Parser?"  "XML::Parser."  "OK, and what about my mod‐
49       ule's version?"  "Ohyeah.  That's 3.11."  By this time, days have
50       passed, and what should have been a simple operation -- reporting the
51       version of Perl and relevent modules, has been needlessly complicated.
52
53       This module is for simplifying that task.  If you add "use Module::Ver‐
54       sions::Report;" to a program (especially handy if your program is one
55       that demonstrates a bug in some module), then when the program has fin‐
56       ished running, you well get a report detailing the all modules in mem‐
57       ory, and noting the version of each (for modules that defined a $VER‐
58       SION, at least).
