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

Note that Carp doesn't automatically include a stack trace, that's only if you do perl -MCarp=verbose script.pl or $Carp::Verbose=1;, or you explicitly use confess. I like to use Carp in my modules because it reports the error as coming from the user's code, rather than the module itself, which makes more sense for many error cases (like incorrect parameters). When it's an internal error that I don't expect the user to see (at least not often), I'll sometimes use confess to get the full stack trace.

$ cat Foo.pm package Foo; use warnings; use strict; use Carp; sub one { die "Bad call to one"; } sub two { carp "Bad call to two"; } sub three { confess "Some error in three"; } 1; $ perl -I. -MFoo -le 'Foo::one' Bad call to one at Foo.pm line 5. $ perl -I. -MFoo -le 'Foo::two' Bad call to two at -e line 1. $ perl -I. -MFoo -le 'Foo::three' Some error in three at Foo.pm line 7. Foo::three() called at -e line 1

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.
