I haven't had any reason to use CAD software for a while now,
and I have completed my primary goal of
creating custom toolbars and custom menus for LibreCAD.
The work I have done for 2.2.0 regarding the command-line
(among other things) is complete.
You can read about the command-line changes here:
You can check the 2.2.0 milestone's closed issues for more information.
I became a developer when I realized a work force didn't exist
to implement the changes I was suggesting.
This is mostly a "do it yourself" project.
Before contributing I highly recommend understanding the license.
I was inspired to work on LibreCAD for over a year,
but that wave of inspiration came to its inevitable end.
My interests are very different now;
and I haven't done any programming in a few months.
I might comment on issues I have some connection with;
however, I don't recommend waiting for me to react.
You can contact me if you have any questions about a change I've made.
