Sally/Kevin, :)
The short answer is that Exporter is used when creating Perl modules. It
allows other programs/modules to import functions and variables, either
explicitly or implicitly, into their own namespace.
Long answer -- see 'perldoc Exporter' on most systems with Perl installed.
On the subject, as someone who is relatively new to writing their own
modules, I have a namespace/scoping question. I think I know the answer,
but I wanted to get the lists' insight.
Let's say I have my main program, 'control.pl'. In this program, I 'use
myModule;' which currently exports a single function. Now, from
'myModule.pm', I want to 'use anotherModule;' which exports all but two
functions.
Now, within 'anotherModule.pm', I wish to read from a variable in
'myModule.pm'. Having assumed that, since the function needing the variable
was imported into 'myModule.pm's namespace, I am simply looking at
'$variable'. This does not work. However, I *can* get to it by
'$myModule::variable'.
What am I missing here? Why can I not access a parent package's variables
within the sibling's namespace? Or, am I just WAY off base and missing the
entire concept. :) Thanks in advance.
