Author:

Message:

fixed grammar so that outer {} and [] are no longer included in the (bracket_)block values
using bracket_block instead of hardcoded pattern for matching hints in formspec
removed dynamic lists from the grammar
some general code cleanup and tidying, in FormBuilder.pm and grammar
added fb.pl to the MANIFEST
bumped back FB version requirement to 3.0 (Makefile.PL)
test for FB3.02 for using growable fields; warn and ignore if verison isn't high enough

    10581053given). Growable fields have a button that allows the user to add a 
    10591054copy of the field input. Currently, this only works for C<text> and 
    1060 C<file> fields. Growable fields also require JavaScript to function 
    1061 correctly. 
     1055C<file> fields, and you must have L<CGI::FormBuilder> 3.02 or higher.

    1091 There is another form of the C<!list> directive: the dynamic list: 
    1092  
    1093     !list RANDOM &{ map { rand } (0..5) } 
    1094  
    1095 The code inside the C<&{ ... }> is C<eval>ed by C<build>, and the results 
    1096 are stuffed into the list. The C<eval>ed code can either return a simple 
    1097 list, as the example does, or the fancier C<< ( { value1 => 'Description 1'}, 
    1098 { value2 => 'Description 2}, ... ) >> form.

    1100 I<B<NOTE:> This feature of the language may go away unless I find a compelling 
    1101 reason for it in the next few versions. What I really wanted was lists that 
    1102 were filled in at run-time (e.g. from a database), and that can be done easily 
    1103 enough with the CGI::FormBuilder object directly.>
