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

I've sometimes used Carp, but in general found that I didn't really need the more extensive output

carp and croak don't make the output more extensive; they just report the caller to be the source of the error instead of the line where the error was found.

$ perl -Mlib=. -MMod -e'Mod::foo();' Insufficient arguments at line 5. # carp Insufficient arguments at -e line 1. # warn

They also have the advantage of being able to produce a full stacktrace on demand (e.g. PERL5OPT=-MCarp::Always). ...Oops, that also works for warn and die.

$ PERL5OPT=-MCarp::Always perl -Mlib=. -MMod -e'Mod::foo();' Insufficient arguments at line 5. Mod::foo() called at -e line 1 Insufficient arguments at line 6. Mod::foo() called at line 6. Mod::foo() called at -e line 1

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.
