NAME
    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.
