> the module, in which the login function appears?

Don't know what you mean with "appears" ..

  1. If you want to know which modules actually use this method (!) , ...

    ... you could use caller inside the method to report the locations at runtime.

    (not sure if applying B::Xref helps with methods)

  2. If you want to know where the method was defined ...

    ... you can might be able to use ->can to get the function's reference and use introspection with B to find the origin. (untested, will update code)

  • my $c_ref = $obj->can("method_name") will return the reference of the method
  • my ($file, $line) = get_code_location($c_ref) in Sub::Identify allows you to retrieve the original source location

the latter can be done without extra module using some half cryptic B code, but I'm reluctant digging it out.

IIRC an example can be found in the O'Reilly book "Perl Hacks" or google is your friend.

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 or How to display code and escape characters are good places to start.
