       CGI::FormBuilder::Source - Source adapters for FormBuilder

SYNOPSIS

           # Define a source adapter

           package CGI::FormBuilder::Source::Whatever;

           sub new {
               my $self  = shift;
               my $class = ref($self) || $self;
               my %opt   = @_;
               return bless \%opt, $class;
           }

           sub parse {
               my $self = shift;
               my $file = shift || $self->{source};

               # open the file and parse it, or whatever
               my %formopt;
               open(F, "<$file") || die "Can't read $file: $!";
               while (<F>) {
                   # ... do stuff to the line ...
                   $formopt{$fb_option} = $fb_value;
               }

               # return hash of $form options
               return wantarray ? %formopt : \%formopt;
           }

DESCRIPTION

       This documentation describes the usage of FormBuilder sources, as well as how to write
       your own source adapter.

       An external source is invoked by using the "source" option to the top-level "new()"
       method:

           my $form = CGI::FormBuilder->new(
                           source => 'source_file.conf'
                      );

       This example points to a filename that contains a file following the
       "CGI::FormBuilder::Source::File" layout. Like with the "template" option, you can also
       specify "source" as a reference to a hash, allowing you to use other source adapters:

           my $form = CGI::FormBuilder->new(
                           fields => \@fields,
                           source => {
                               type => 'File',
                               source => '/path/to/source.conf',
                           }
                      );

       The "type" option specifies the name of the source adapter. Currently accepted types are:

           File  -  CGI::FormBuilder::Source::File

       In addition to one of these types, you can also specify a complete package name, in which
       case that module will be autoloaded and its "new()" and "parse()" routines used. For
       example:

           my $form = CGI::FormBuilder->new(
                           fields => \@fields,
                           source => {
                               type => 'My::Source::Module',
                               somefile => '/path/to/source.conf',
                           }
                      );

       All other options besides "type" are passed to the constructor for that source module
       verbatim, so it's up to you and/or the source module on how these additional options
       should be handled.
