how do you include multiple modules using one module

diabelek has asked for the wisdom of the Perl Monks concerning the following question:

Is there any way to include multiple modules using a single module. IE in C, you could have #include "my_common.h" which would have #include "file_a.h", #include "file_b.h"...

In perl, the only thing I can find that is comparable to write a line of code using eval, join and map but that still has to be written in every file.

We're looking for a solution that would let users do "use framework;" to include the whole framework we have written or chunks of it using qw(a b c). In our framework modules, we could use "use framework_common;" to include or common logging, constants, etc files.

      I.e. ToolSet

      -xdg

    You can use Filter::Macro:

    package framework use Filter::Macro; use strict; use warnings; use ... .... 1;

    Then, a program or module that says use Filter::Macro will expand lines below use Filter::Macro into their own code

    You can also take a look at Toolkit

    Toolkit looks like it may be on the right track... but don't ignore the obvious, this sort of thing works:
    package Module::DemoGroupExport; # doom@kzsu.stanford.edu # 26 Feb 2009 =head1 NAME Module::DemoGroupExport - repaces many "use" statements with one =head1 SYNOPSIS use Module::DemoGroupExport qw( carp croak Dumper mkpath dirname ); my $file = shift; my $loc = dirname( $file ); unless (-d $loc) { carp "Creating $loc..."; mkpath( $loc ) or croak "Could not create $loc: $!"; } =head1 DESCRIPTION Demonstration of a simple strategy for ganging together multiple use statments for many Exporter-based modules into one, so that you can replace many lines of commonly used "use" statements with a single one. Note: automatic exporting is now frowned upon -- better to explicitly state what you want. =head2 EXPORT None by default. =cut use 5.8.0; use strict; use warnings; use Carp qw( carp cluck croak confess shortmess longmess ); use Data::Dumper qw( Dumper ); use File::Path qw( mkpath ); use File::Basename qw( fileparse basename dirname ); use File::Copy qw( copy move ); use Cwd qw( cwd abs_path ); require Exporter; our @ISA = qw(Exporter); our %EXPORT_TAGS = ( 'all' => [ qw( carp cluck croak confess shortmess longmess Dumper mkpath fileparse basename dirname copy move cwd abs_path ) ] ); our @EXPORT_OK = ( @{ $EXPORT_TAGS{'all'} } ); our @EXPORT = qw( ); # exported into callers namespace by default. # (don't use this without a very good reason.) our $VERSION = '0.01'; 1; =head1 SEE ALSO o The cpan module L<Toolkit> =head1 AUTHOR Joseph Brenner, E<lt>doom@kzsu.stanford.eduE<gt> =head1 COPYRIGHT AND LICENSE Copyright (C) 2009 by Joseph Brenner This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself, either Perl version 5.8.2 or, at your option, any later version of Perl 5 you may have available. =head1 BUGS None reported... yet. =cut
