For all of you Perl-programming nuts (is it really just me?)
Coming soon: new setup for CAD::Drawing::IO which allows additional modules
to be easily added.
Changes to the compile-time requirements of CAD::Drawing::IO will now allow
the presence or absence of additional IO::* modules without any changes to
IO.pm.
What this means for most users (if there are any) is that you will no longer
have to make code changes at the module level to eliminate the
CAD::Drawing::IO::DWGI requirement (which means you can work on little
geometry programs in your own little world, leaving autocad and the OpenDWG
toolkit out of it.)
What this means for Perl module developers: easily add new formats to the
capabilities of CAD::Drawing simply by making a module like
CAD::Drawing::IO::STEP which provides a load() and/or save() function and
declares a couple of variables to make itself known.
This easily makes room for the addition of a wrapper on the Dime dxf library,
or on the python dwg library by Art Haas or possibly just a pure-perl
implementation of those.
Comments / suggestions welcome.
I plan to redo the makefiles for all of these module this weekend, so
hopefully most of them start to be easily installable via cpan.
