=head1 NAME

pp-yaml - Pretty-print (and colorize) YAML

=head1 VERSION

This document describes version 0.160 of pp-yaml (from Perl distribution App-SerializeUtils), released on 2018-01-29.

=head1 DESCRIPTION

By default, when in interactive mode will pretty-print and colorize YAML using
L<YAML::Tiny::Color>, and when piped will pretty-print YAML using L<YAML::XS>.

=head1 OPTIONS

=over

=item * --color, --no-color

Force using color (YAML::Tiny::Color) or no color. The default is to check
whether STDOUT is not piped (interactive mode) to enable color.

=item * --pp

Force using a PP (pure-Perl) module (currently L<YAML::Old>) instead of the
default L<YAML::XS>.

=item * --xs

Force using an XS module (currently L<YAML::XS>).

=back

=head1 ENVIRONMENT

=head2 COLOR

Boolean. Set default for color.
