CGI::Application::Plugin::ConfigAuto - Easy config file management for

     use CGI::Application::Plugin::ConfigAuto (qw/cfg/);

    In your instance script:

     my $app = WebApp->new(PARAMS => { cfg_file => '' });

    In your application module:

     sub my_run_mode {
        my $self = shift;

        # Access a config hash key directly 
        # Return config as hash
        %CFG = $self->cfg; 


    CGI::Application::Plugin::ConfigAuto adds easy access to config file
    variables to your CGI::Application modules. Lazy loading is used to
    prevent the config file from being parsed if no configuration variables
    are accessed during the request. In other words, the config file is not
    parsed until it is actually needed. The Config::Auto package provides
    the framework for this plugin.

    "CGI::Application" promotes re-usable applications by moving a maximal
    amount of code into modules. For an application to be fully re-usable
    without code changes, it is also necessary to store configuration
    variables in a separate file.

    This plugin supports multiple config files for a single application,
    allowing config files to override each other in a particular order. This
    covers even complex cases, where you have a global config file, and
    second local config file which overrides a few variables.

    It is recommended that you to declare your config file locations in the
    instance scripts, where it will have minimum impact on your application.
    This technique is ideal when you intend to reuse your module to support
    multiple configuration files. If you have an application with multiple
    instance scripts which share a single config file, you may prefer to
    call the plugin from the setup() method.

     # In your instance script
     # value can also be an arrayref of config files
     my $app = WebApp->new(PARAMS => { cfg_file => '' })

     # OR ... 

     # Pass in an array of config files, and they will be processed in order.  

    Your config files should be referenced using the syntax example above.
    Note that the key "config_files" can be used as alternative to cfg_file.

    The format is detected automatically using Config::Auto. It it known to
    support the following formats: colon separated, space separated, equals
    separated, XML, Perl code, and Windows INI. See that modules
    documentation for complete details.

     # Access a config hash key directly 
     # Return config as hash
     my %CFG = $self->cfg; 

     # return as hashref
     my $cfg_href = $self->cfg;
    A method to access project configuration variables. The config file is
    parsed on the first call with a perl hash representation stored in
    memory. Subsequent calls will use this version, rather than re-reading
    the file.

    In list context, it returns the configuration data as a hash. In scalar
    context, it returns the configuration data as a hashref.

    "config()" in CGI::Application::Standard::Config is provided as an alias
    to cfg() for compliance with CGI::Application::Standard::Config. It
    always exported by default per the standard.

    "std_config()" in CGI::Application::Standard::Config is implemented to
    comply with CGI::Application::Standard::Config. It's for developers.
    Users can ignore it.

     # Usual
     # Supply the first format, guess the second
     $self->cfg_file('',{ format => 'perl' } );

    Supply an array of config files, and they will be processed in order. If
    a hash reference if found it, will be used to supply the format for the
    previous file in the array.

    Here's a simple example of my favorite config file format: Perl. Having
    the "shebang" line at the top helps "Config::Auto" to identify it as a
    Perl file. Also, be sure that your last statement returns a hash


        my %CFG = ();

        # directory path name
        $CFG{DIR} = '/home/mark/www';

        # website URL
        $CFG{URL} = '';
