CGI::Se...Handler(3)

💖 CGI::Session::ErrorHandler 💖

okay bestie, so this is the manual page for CGI::Session::ErrorHandler, from the User Contributed Perl Documentation corner of the universe ✨ (yes, that parenthetical is the manual name, we're folding it in, don't @ me).

---

🌸 NAME 🌸

CGI::Session::ErrorHandler — the error-handling routines for CGI::Session, periodt 💅

---

🦋 SYNOPSIS 🦋

like, here's the whole vibe in code form, copy it exactly bestie:

require CGI::Session::ErrorHandler;
@ISA = qw( CGI::Session::ErrorHandler );

sub some_method {
    my $self = shift;
    unless (  $some_condition ) {
        return $self->set_error("some_method(): \$some_condition isn't met");
    }
}

---

✨ DESCRIPTION ✨

so CGI::Session::ErrorHandler literally provides the set_error() and errstr() methods — one for setting error messages and one for accessing them — from inside CGI::Session's components 🫶

and listen, this one's a note for the driver developers out there: you should be using this method to give your code CGI::Session-standard error handling routines. like, that's the whole assignment, iykyk 👑

---

🎀 METHODS 🎀

• set_error($message) — implicitly defines $pkg_name::errstr and sets its value to $message. the return value is always undef, no cap, every single time 💀
• errstr() — returns whatever value was set by the most recent call to set_error(). and if no message has been set yet? you get the empty string back, so the message can still concatenate without a warning 🌈 (yes, that's a real feature, not a bug, slay)
