=head1 NAME
Devel::REPL::Plugin::Colors - Add color to return values, warnings, and errors
=head1 VERSION
version 1.003028
=head1 SYNOPSIS
use Devel::REPL;
my $repl = Devel::REPL->new;
$repl->load_plugin('LexEnv');
$repl->load_plugin('History');
$repl->load_plugin('Colors');
$repl->run;
=head1 DESCRIPTION
Colors are very pretty.
This plugin causes certain prints, warns, and errors to be colored. Generally
the return value(s) of each line will be colored green (you can override this
by setting C<< $_REPL->normal_color >> in your rcfile). Warnings and
compile/runtime errors will be colored with C<< $_REPL->error_color >>. This
plugin uses L<Term::ANSIColor>, so consult that module for valid colors. The
defaults are actually 'green' and 'bold red'.
