This library contains components commonly used in designing and moching up
|
|
|
|
|
mechanical designs. It is currently unfinished and you can expect some API
|
|
|
|
|
changes, however many things are already working.

== Usage ==
|
|
|
|
|
You can import these files in your scripts with "use <MCAD/*.scad>", but some
|
|
|
|
|
files include useful constants which will be available with "include <MCAD/*.scad>",
|
|
|
|
|
which should be safe to use on all included files (ie. no top level code should
|
|
|
|
|
create geometry).

== Development ==
|
|
|
|
|
You are welcome to fork this project in github and request pulls. I will try to
|
|
|
|
|
accomodate the community as much as possible in this. If for some reason you
|
|
|
|
|
want collaborator access, just ask.
|
|
|
|
|
|
|
|
|
|
Github is fun (and easy), but I can include code submissions and other
|
|
|
|
|
improvements directly, and have already included code from various sources
|
|
|
|
|
(thingiverse is great :)
|
|
|
|
|
|
|
|
|
|
=== Code style ===
|
|
|
|
|
I'd prefer to have all included code nicely indented, at least at the block
|
|
|
|
|
level, and no extraneous whitespace. I'm used to indent with four spaces as
|
|
|
|
|
opposed to tabs or other mixes of whitespace, but at least try to choose a style
|
|
|
|
|
and stick to it.

=== Testing ===
|
|
|
|
|
I've started a minimal testing infrastucture for OpenSCAD code. It's written in
|
|
|
|
|
python and uses py.test (might be compatible with Nose also). Just type py.test
|
|
|
|
|
inside the lib dir in a terminal and you should see a part of the tests passing
|
|
|
|
|
and tracebacks for failing tests. It's very simplistic still, but it should test
|
|
|
|
|
that no syntax errors occur at least.
