I want my code to call some subroutines in a custom module only if that module
exists on the system. I can think of at least three techniques to determine
if the module exists: scan @INC, use UNIVERSAL::can (not sure that would
work), or put the code in an eval block. What is the best solution? I think
an eval block sounds right, but I'm not sure. My guess would look something like:
eval
{
use module;
module::subroutine();
};
I know of a module that is almost done with that has a function called
gotmodule()
if( gotmodule('Foo::Bar') ) {
print "Foo::Bar is version $Foo::Bar::VERSION\n";
} else {
print "You should install Foo::Bar it is pretty nice\n";
}
If you're insterested I can let you know when it is done...
(I'm tracking it for the Author..)
