List all modules and versions used by a program

Need Help??

    Description:
     Sometimes things break because code that worked with certain versions of modules does not work with others. This short block just dumps all the modules in use, with their version numbers when a script exits. By doing it in an END block you get a realistic picture of what got loaded and it will still print if your code dies for whatever reason. 
  

END{ 
    no strict; # access $VERSION by symbolic reference
    print map {
        s!/!::!g; 
        s!.pm$!!; 
        sprintf "%-20s %s\n", $_, ${"${_}::VERSION"} 
    } sort keys %INC; 
};

Possibly also of interest would be Module::ScanDeps from CPAN (although that's more of a static analysis than after-the-fact diagnostic). The cake is a lie. The cake is a lie. The cake is a lie.	[reply]

There's also Devel::Modlist, used like `perl -d:Modlist=options script.pl perl -MDevel::Modlist=options script.pl # equivalent` [download] which is handy as it doesn't require any modification of the program itself. lodin	[reply] [d/l]

take a look to this one too. HtH L* There are no rules, there are no thumbs.. Reinvent the wheel, then learn The Wheel; may be one day you reinvent one of THE WHEELS.	[reply] [d/l]
