Graphics::Toolkit::Color::Manual::Error(3) User Contributed Perl Documentation


NAME
       Graphics::Toolkit::Color::Manual::Error - GTC error handling

SYNOPSIS
       This manual page explains how GTC error messages behave and how to
       change it to a preferred behaviour.

MODES
       If a user does misspell a method argument or passes bad data, he will
       get an error. But GTC knows 5 ways to deliver that error.

   carp
       Warning with a stack trace from the perspective of the GTC caller via
       "carp" (Carp). This is the default mode.

   croak
       Exception with a stack trace that has to be dealt with using something
       alike Try::Tiny or "eval".

   say
       Normal string to STDOUT from the perspective of the GTC method that has
       the issue with bad input.

   die
       Exception with info from the perspective of the GTC method.

   quiet
       The error will be suppressed. Please check if there is at least a GTC
       object returned.

SETUP
       The error is chosen with the use-statement that is also responsible for
       all symbol imports.

         use Graphics::Toolkit::Color qw/color/, error => 'quiet';
