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.
