Testing if a module is there

[gao_bolin]

I would like to be able to use a module if it is present, without
generating an error if it is not. Is there a technique in Perl similar
to the try/catch technique used in some other languages to do that?

Thanks

B.

perldoc -f eval

perldoc -f require

Let's say you wanted to include the Win32::Console module, but only
give a warning if the module was not found. You could try:

eval { require Win32::Console };
warn "Cannot load module Win32::Console: $@" if $@;

I hope this helps.
