I think you're confusing input validation with error messages here. A script should produce meaningless fluff for errors a visitor cannot fix anyway - like could not open /path/to/config/file. That stuff belongs in the server error log and nowhere else. Of course it is useful to tell the user what went wrong if his input was rejected for some reason, but that's not quite the same as an error message. As Ovid wrote in his tutorial, your script may break at any - even unforseen - point, so you have no control about what information a visitor may see if you indiscriminately set fatalsToBrowser.

Makeshifts last the longest.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
