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

I confess that I don't use mod_perl much, but the magic voodoo that you probably need here is the Apache directive:   SetEnv PERL5LIB path:path:path

As you may or may not know, @INC is the list of places that Perl will search when looking to find any library. You can see this list by entering perl -V (note the upper-case 'V'). This list is searched from front-to-back.

Many things can “prepend” entries to this list (that is to say, “add them to the front of it”):

  • use lib pragmas.
  • PERL5LIB and various other “environment variables.”
  • Your own program-voodoo:   @INC is just an ordinary list...

By using this directive in Apache, you specify these environment-variable settings in the context of this <VirtualHost>. (You can probably use them in an .htaccess file, too.)

The value of this environment-variable is a list of path-names separated by colons. I always use absolute path-names.

One interesting bit of woot-woot! voodoo is the module FindBin, which can be used with use lib in the manner described in perldoc FindBin

Title:
Use:  <p> text here (a paragraph) </p>

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.
