CGI::Application::Plugin::AutoRunmode::FileDelegate(3) delegate CGI::App run modes to a directory of files


# in file runmodes/
sub {
my ($app, $delegate) = @_;
# do something here

# in file runmodes/
sub {
# do something else

package MyApp;
use base 'CGI::Application';
use CGI::Application::Plugin::AutoRunmode
qw [ cgiapp_prerun];
use CGI::Application::Plugin::AutoRunmode::FileDelegate();

sub setup{
my ($self) = @_;
my $delegate = new CGI::Application::Plugin::AutoRunmode::FileDelegate
$self->param('::Plugin::AutoRunmode::delegate' => $delegate);

# you now have two run modes
# "my_run_mode" and "another_run_mode"


Using this module, you can place the definition of your run modes for a CGI::Application into directory of files (as opposed to into a Perl module).

Each run mode is contained in its own file, named for a run mode called foo. The run modes are lazily evaluated (on demand) for each request. In the case of mod_perl this means you can update them without restarting your web server. In the case of plain CGI it means a reduced startup cost if you have many run modes (because only the one that you need gets parsed and loaded, along with dependent modules).

Using more than one directory with runmodes

You can pass multiple directory paths to the constructor for the delegate:

        my $delegate = new CGI::Application::Plugin::AutoRunmode::FileDelegate
                        ('/path/to/runmodes', '/path/to/more_runmodes')

In this case, they will be searched in order. The first matching file becomes the run mode. In the case of errors with that file, the module will croak (and not continue the search in the remaining directories).


With all the namespace nesting going on the name of this module has reached an intolerable Java-esque length.
