=head2 run_if_script
-The run_if_script method is designed to be used at the end of the script
+The C<run_if_script> method is designed to be used at the end of the script
or .pm file where your application class is defined - for example:
## my_web_simple_app.pl
will work fine (and you can rename it to lib/HelloWorld.pm later to make it
a real use-able module).
-However, it detects if it's being run as a script (via testing $0) and if
-so attempts to do the right thing.
+Specifically, this true value is a PSGI app. You can you can pass the return
+value of C<HelloWorld->run_if_script> to code expecting a PSGI app and you can
+treat the file as though it were a standard PSGI application file (*.psgi). For
+example you can start it up with C<plackup>
+
+ plackup my_web_simple_app.pl
+
+or C<starman>
+
+ starman my_web_simple_app.pl
+
+If C<run_if_script> is called from a situation where there is no caller, i.e. as
+C<perl my_web_simple_app.pl> on the shell, or by a web server, it will call the
+C<run> method to run the actual application itself.
+
+=head2 run
If run under a CGI environment, your application will execute as a CGI.
FastCGI process (this works both for dynamic shared-hosting-style FastCGI
and for apache FastCgiServer style setups).
-If run from the commandline with a URL path, it runs a GET request against
-that path -
+If neither of these are the case, it defaults to running the C<run_cli> method
+with C<@ARGV> as arguments.
+
+=head2 run_cli
+
+This method is meant to be overriden to implement your own command line mode for
+the app, be this a debugger, interactive mode or page generator.
+
+Its default implementation calls the C<run_cli_request> method with the
+arguments it was given, or, if that indicates failure by returning 0, calls
+C<cli_request_usage> to print a message explaining the correct CLI usage.
+
+=head2 run_cli_request
+
+Looks at the arguments passed to it, typically C<@ARGV> captured somewhere up the
+callstack, and tries to convert that into a sensible request against the
+application, which it then runs. Any results are printed to C<STDOUT>. Returns
+C<1> if it was able to run the request, and C<undef> if it was not able to
+covert the arguments into a sensible request.
+
+If run with a URL path, it runs a GET request against that path -
$ perl -Ilib examples/hello-world/hello-world.cgi /
200 OK
will generally do the right thing.
-Additionally, you can treat the file as though it were a standard PSGI
-application file (*.psgi). For example you can start up up with C<plackup>
+To send basic authentication credentials, use user:pass@ syntax -
- plackup my_web_simple_app.pl
+ $ ./myapp GET bob:secret@/protected/path
-or C<starman>
+=head2 cli_request_usage
- starman my_web_simple_app.pl
+Prints a message explaining how to pass CLI parameters. Can be overridden for
+your own purposes.
=head2 to_psgi_app
This method can be called as a class method, in which case it implicitly
calls ->new, or as an object method ... in which case it doesn't.
-=head2 run
-
-Used for running your application under stand-alone CGI and FCGI modes.

-I should document this more extensively but run_if_script will call it when
-you need it, so don't worry about it too much.

=head2 run_test_request
my $res = $app->run_test_request(GET => '/' => %headers);
create an L<HTTP::Request> object by hand or use the C<POST> subroutine
provided by L<HTTP::Request::Common>.
+If you prefix the URL with 'user:pass@' this will be converted into
+an Authorization header for HTTP basic auth:
+
+ my $res = $app->run_test_request(
+ GET => 'bob:secret@/protected/resource'
+ );
