This is something in between an RFC and an ANNOUNCE - maybe I went too far in the development before discussing it here.
This small module provides a structure that can store DateTimes with attributes (as discussed many times here), but it can do a lot more than that. "DateTime::Event::Spreadsheet - A collection of named events" DOWNLOAD - Single executable file with module + pod + examples + tests: http://www.ipct.pucrs.br/flavio/perl/DateTime-Event-Spreadsheet-0.0_2.pl SYNOPSIS use DateTime::Event::Spreadsheet; $dtes = DateTime::Event::Spreadsheet->new; $dtes->set( 'birthday', value => DateTime->new( year => 1964 ) ); print $dtes->cell( 'birthday' )->datetime; DESCRIPTION DateTime::Event::Spreadsheet is a class for representing a collection of events and the relations between them. For example, a Spreadsheet could be used to store business hours information, together with holidays. A cell could be tied to a database value, and other cells would be automatically updated when that value changes. Each event or function is stored in a Spreadsheet cell. All cells have names (or keys), such as "A1", "B10", or "birthday". A Spreadsheet may contain any combination of DateTime::* objects, including DateTime::Event::*, DateTime::Set, DateTime::Span, DateTime::SpanSet, other Spreadsheets, and Perl subroutines. USAGE - Methods * new This is the Spreadsheet constructor. It takes no parameters. * set $dtes->set( 'now', value => DateTime->now ); Sets a cell contents. A unique key must be provided. Setting the same key again will overwrite the previous contents. A cell may contain any type of DateTime::* objects, or a Perl subroutine reference. Exceptions are handled by the object into the cell. This is an example of how to put a Perl subroutine in a cell: $dtes->set( 'now', value => sub { DateTime->now } ); A parameter list may be specified, containing cell names. The cell values are provided through @_ at run time: $dtes->set( 'later', param => [ 'now' ], value => sub { $_[0]->add( hours => 1 ) } ); * cell my $value = $dtes->cell( 'now' ); print $value->datetime; Returns the cell value. If the cell contains a function, cell() will evaluate the function and return the result. --- - Flavio S. Glock
