These messages were perhaps originally intended as a debuggin aid but now add clutter to the output panes. Remaining messges are mostly the result of methods to display attributes of an object (which one could call from the Python console) or actually provide some information which would not be obvious from the circumstances
Avoid `Draft.py` in the `make_polar_array` function because
it creates a circular dependency.
Use function to find the object in `make_polar_rarray`.
Now the make function accepts as input a `"String"` which must be
the `Label` of an object in the document, so it is easier to create
arrays interactively from the Python console.
Clean up the GuiCommand and task panel code, and avoid printing
messages to the terminal, as this is already done
by the make function.
In Python 3 `super()` can be used without an argument
in order to get the parent class, `super()`.
In Python 2 the present class must be used as an argument,
`super(ThisClass, self)`.
This commit is done to support Python 2,
as without it all Gui Command tools will be broken
and will fail to launch, even if the unit tests pass.
Also, set the `__metaclass__` variable to `type`.
This is done to turn all classes into "new style" classes
in Python 2. This is required so `super()` works correctly
in this version of Pyton.
This commit can be reverted once Python 2 support
is completely dropped, and only Python 3 compatible code
is used.
The internal GuiCommand classes are renamed to `CircularArray`,
`OrthoArray`, and `PolarArray`. This is a shorter name than the
previous `GuiCommandCircularArray`, `GuiCommandOrthoArray`,
and `GuiCommandPolarArray`.
These classes are not part of the scripting interface of Draft
so we don't risk breaking previous files.
Small spacing fixes like imports in separate lines
for more clarity, the module docstrings,
and the position of the license.
Remove unnecessary check for the graphical interface
as this command should be imported when the interface
is already up and running.
Use proper `ToDo` class instead of importing `DraftGui`.
