=head1 DESCRIPTION

This is a quick & dirty second attempt at making L<TAP::Formatter::HTML> easier
to use from the command line.  It will change once L<App::Prove> has better
support for plugins than need to take cmdline data.

The original goal was to be able to specify all the args on the cmdline, ala:

  prove --html=output.html --css-uri foo.css --css-uri bar.css --force-inline-css 0

But this is currently not possible with the way the L<App::Prove> plugin system
works.

As a compromise, you must use the following syntax:

  prove -P HTML=arg1:val1,arg2:val2,...

Where I<argN> is any L<TAP::Formatter::HTML> parameter that is configurable via
C<%ENV>.

=head2 Example

  prove -P HTML=outfile:out.html,css_uri:style.css,js_uri:foo.js,force_inline_css:0

This will cause L<prove> to load this plugin, which loads L<TAP::Formatter::HTML>
for you, and sets I<formatter> to C<TAP::Formatter::HTML> to save you some typing.

To configure L<TAP::Formatter::HTML>, the following C<%ENV> vars are set:

  TAP_FORMATTER_HTML_OUTFILE=out.html
  TAP_FORMATTER_HTML_FORCE_INLINE_CSS=0
  TAP_FORMATTER_HTML_CSS_URIS=style.css
  TAP_FORMATTER_HTML_JS_URIS=func.js

Yes, you can pass 2 or more I<css_uri> or I<js_uri> args.

=head2 %ENV vars?!

Briefly, L<App::Prove> currently only lets you specify the C<formatter_class> for
L<TAP::Harness>, it doesn't let you instantiate a formatter, or pass config to
the formatter.

I<Yes, I know %ENV vars are a horrible way to do things.>  If it bugs you too,
then join the L<TAP::Harness> devs and help us fix it ;-).
