( #3333=superdoc: print w/replies, xml ) Need Help??

Your name space isn't poluted:

use strict; use warnings; use mymodule; print "My Test\n"; Func1(); # ERROR! Func2("Fluffy", 5); # ERROR!

But check this out:

use strict; use warnings; use mymodule qw( Func1 ); # Import Func1 #use mymodule qw( Func2 ); # This won't work since # Func2 is not in @EXPORT_OK. print "My Test\n"; Func1(); Func2("Fluffy", 5); # ERROR!

You should never export methods. As you can see, there's no reason to do so. All functions in a package are tied to the object blessed to that package, whether you use Exporter or not.

and how can I prevent it as it seems to be allowing everything into the calling script's namespace?

It's possible to disguise a function using lexicals and/or closures so that noone outside the package can call it, but there's no need to do so. Write proper documentation instead.

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
