NAME

Plack::App::File::PYX - Plack PYX directory application.

SYNOPSIS

 use Plack::App::File::PYX;

 my $obj = Plack::App::File::PYX->new(%parameters);
 my $psgi_ar = $obj->serve_path($env, $file);
 my $app = $obj->to_app;

METHODS

new

 my $obj = Plack::App::File::PYX->new(%parameters);

Constructor.

Returns instance of object.

  • content_type

    Content-Type of serialized output. There is possibility of callback (reference to code) with $file argument which return content type string.

    Default value is 'text/html'.

  • encoding

    Set the file encoding for text files. Defaults to 'utf-8'.

  • file

    The file path to create responses from. Optional.

    If it's set the application would ALWAYS create a response out of the file and there will be no security check etc. (hence fast). If it's not set, the application uses "root" to find the matching file.

  • indent

    Set Tags::Output::* class for output serialization.

    Default value is Tags::Output::Raw.

  • root

    Document root directory. Defaults to "." (current directory)

serve_path

 my $psgi_ar = $obj->serve_path($env, $file);

Process file on disk and serve it to application.

Returns reference to array (PSGI structure).

to_app

 my $app = $obj->to_app;

Creates Plack application.

Returns Plack::Component object.
