How can you get a handle on the directory that a module is located in from within that module's code?

Try __FILE__. See perldata, section "special literals". Drop the file's basename from that string, possibly using File::Basename.

A test revealed that this can produce a relative path; rel2abs() from File::Spec::Functions can remedy that.

For example, test module

package Foo; use File::Spec::Functions qw(rel2abs); use File::Basename; my $dir = (fileparse(rel2abs(__FILE__)))[1]; print "Foo directory: $dir\n"; 1;

IMO it's safest to indeed set a variable with this directory in the top level of the module, as I do here, so it always gets set when the module is loaded.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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 How to display code and escape characters are good places to start.
