=head1 NAME

HTML::WikiConverter::WebApp - Web interface to HTML::WikiConverter

=head1 SYNOPSIS

Inside the index.cgi instance script (which is included with this
distribution):

  #!/usr/bin/perl
  use HTML::WikiConverter::WebApp;
  
  my %config = (
    template_path => '/path/to/web/templates',
  );

  HTML::WikiConverter::WebApp->new( PARAMS => \%config )->run;

=head1 DESCRIPTION

This module provides a L<CGI::Application> interface to
L<HTML::WikiConverter> and all installed dialect modules.

Refer to the INSTALL file for installation instructions.

=head1 QUERY PARAMETERS

This application accepts a number of query parameters to control its
behavior. The most basic is the run mode parameter, C<m>. This
application can be in one of two run modes: C<"new"> or C<"convert">.
(These correspond to the C<new_page()> and C<output_page()> methods,
respectively.) C<"new"> causes a new page to be displayed, while
C<"convert"> displays the results of html-to-wiki conversion.

Additional query parameters can be passed independent of run mode:

=over 4

=item * source_type

One of C<"raw_html">, C<"from_uri">, or C<"sample_html">.

=item * dialect

Any installed dialect, eg C<"MediaWiki">.

=item * base_uri

Base URL to be used for converting relative links to absolute ones.

=item * wiki_uri

Template for wiki URLs. When scanning the HTML source, if a URL (as in
an C<a href> or C<img src> attribute value) is found matching this
template, it will be treated to a link to a wiki
article/image. Consult L<HTML::WikiConverter/ATTRIBUTES> for more
information.

Note that this is a bit less flexible than using the C<wiki_uri>
attribute directly in L<HTML::WikiConverter>. That attribute allows
multiple templates, allows coderefs, and regexps, etc. This option
only accepts a single scalar representing a very simple wiki URL
template.

=item * show_parsed_html

If enabled, an additional textarea containing the parsed HTML will be
displayed.

=item * escape_entities

If enabled, unsafe HTML entities ("E<lt>", "E<gt>", and "E<amp>") will
be encoded using L<HTML::Entities>.

=item * format

One of C<"html"> or C<"xml">. Determines the type of output displayed
by this application.

=head1 METHODS

=head2 setup

Sets up the app for L<CGI::Application>.

=cut

sub setup {
  my $self = shift;
  $self->error_mode( 'display_error' );
  $self->tmpl_path( $self->param('template_path') );
  $self->mode_param( 'm' );
  $self->start_mode( 'new' );
  $self->run_modes(
    new     => 'new_page',
    convert => 'output_page',
  );
  $self->header_add( -charset => 'utf-8' );
}

=head2 new_page

Corresponds to the C<new> run mode. Returns a blank form. If arguments
are available on the CGI query string, these are used as default
values for the form fields.

=cut

sub new_page {
  my $self = shift;

  my $tmpl = $self->load_template( 'main.html' );
  $tmpl->param(
    $self->_default_template_params,
  );

  $tmpl->output;
}

=head2 output_page

Corresponds to the C<convert> run mode. Same as C<new_page()> but returns
the wiki markup for the provided html as well.

=cut

  my $self = shift;

}

=head2 display_error

Error-catching method called by L<CGI::Application> if a run mode
fails for any reason. Displays a basic form with a styled error
message up top.

=cut

sub display_error {
  my( $self, $error ) = @_;
