=head1 Name
Text::Markup::None - Turn a file with no known markup into HTML
=head1 Synopsis
use Text::Markup;
my $html = Text::Markup->new->parse(file => 'README');
my $raw = Text::Markup->new->parse(
file => 'README',
options => [ raw => 1 ],
);
=head1 Description
This is the default parser used by Text::Markdown in the event that it cannot
determine the format of a text file. All it does is read the file in (relying
on a L<BOM|https://www.unicode.org/unicode/faq/utf_bom.html#BOM>, encodes all
entities, and then returns an HTML string with the file in a C<< <pre> >>
element. This will be handy for files that really are nothing but plain text,
like F<README> files.
By default this parser is not associated with any file extensions. To have
Text::Markup also recognize files for this module, load it directly and pass
a regular expression matching the desired extension(s), like so:
use Text::Markup::None qr{te?xt};
Normally this module returns the output wrapped in a minimal HTML document
skeleton. If you would like the raw output without the skeleton, you can pass
the C<raw> option to C<parse>.
