Running Logo

To read a Logo file into Logo, use:

>>> Logo.import_logo('filename.logo')
>>> Logo.import_logo_stream(file_like_object)

You should try to give your file_like_object a .name attribute, which will be used in tracebacks as the filename.

When you get a pylogo.common.LogoError exception, typically you can just print exc.description, ':', exc to give the proper error message. Other exceptions should be displayed with whatever your normal Python exception display routine is.

To do a REPL (read-eval-print-loop) use:

>>> Logo.input_loop(input_stream, output_stream)

Interacting With Logo

If you have Python code you want to make available, you can use:

>>> Logo.import_function(python_function, name_override=['foo'])
>>> Logo.import_module(python_module)

The first form imports a single function. It will use the function's name unless you provide name_override, a list of the name/aliases of the function. The second form searches a Python module for functions to add to logo. pylogo.builtins is an example of this kind of module, and Adding Primitives with Python section describes how you can do this.
