package Carp::Always::Color::HTML;
use Carp::Always;
=head1 NAME
Carp::Always::Color::HTML - Carp::Always, but with HTML color
=head1 SYNOPSIS
use Carp::Always::Color::HTML;
or
perl -MCarp::Always::Color::HTML -e'sub foo { die "foo" } foo()'

Like L<Carp::Always::Color>, but forces HTML coloring, regardless of where
STDERR is pointing to.

BEGIN { $Carp::Internal{(__PACKAGE__)}++ }
sub _die {
eval { Carp::Always::_die(@_) };
my $err = $@;
$err =~ s/(.*)/<span style="color:#800">$1<\/span>/;
die $err;
}
sub _warn {
my $warning;
{
local $SIG{__WARN__} = sub { $warning = $_[0] };
Carp::Always::_warn(@_);
}
$warning =~ s/(.*)/<span style="color:#880">$1<\/span>/;
warn $warning;
}
my %OLD_SIG;
BEGIN {
@OLD_SIG{qw(__DIE__ __WARN__)} = @SIG{qw(__DIE__ __WARN__)};
$SIG{__DIE__} = \&_die;
$SIG{__WARN__} = \&_warn;
}
END {
@SIG{qw(__DIE__ __WARN__)} = @OLD_SIG{qw(__DIE__ __WARN__)};
