Basic usage

Simple Perl script, which have two subroutines and there is error inside. Error output via Error::Pure is to console and with ANSI colors. Output formatter is placed in "err_bt_pretty" in Error::Pure::Output::ANSIColor.

Perl script

 use strict;
 use warnings;

 use Error::Pure qw(err);

 sub first {
         my $text = shift;

         second($text);

         return;
 }

 sub second {
         my $text = shift;

         err 'This is error',
                 'Context', $text,
         ;
 }

 first("Hellow world");

Output to stderr

 Context: Hellow world
 main  err     /home/skim/data/gitprac/lang/perl/perl/MODULES/Error-Pure/ex19.pl  19

 main  first   /home/skim/data/gitprac/lang/perl/perl/MODULES/Error-Pure/ex19.pl  24
