commands¶
Main PyGenCad entry point.
The commands sub-module provides helper functions for creating CommandFile and Layer objects targeting specific backends. Functions from the commands sub-module are available at the top level of the PyGenCAD package.
>>> from pygencad import *
>>> from StringIO import StringIO
>>> f = StringIO()
>>> with get_script(f, 'autocad') as script:
... script.cmd("Hello, World!")
...
'l'
>>> "Hello, World!" in f.getvalue()
True
variables¶

functions¶
-
pygencad.
get_script
(filelike, backend)[source]¶ Return an initialized CommandFile object for the requested backend.
>>> from pygencad import * >>> from StringIO import StringIO >>> f = StringIO() >>> get_script(f, 'autocad') <pygencad.autocad.CommandFile object at 0x...> >>> get_script(f, 'spam') Traceback (most recent call last): ... ValueError: Unknown backend ...!
Parameters: - filelike (filelike) – An object with a write method.
- backend (string) – Name of the backend to use, must be in pygencad.backends.
Raises: ValueError if the provided name isn’t in pygencad.backends
Returns: An instantiated CommandFile object for the indicated backend.

pygencad.
get_layer
(backend)[source]¶ Return the layer class for the indicated backend.
>>> from pygencad import * >>> from StringIO import StringIO >>> f = StringIO() >>> get_layer('autocad') # Notice the return isn't an object: <class 'pygencad.autocad.Layer'> >>> get_script(f, 'spam') Traceback (most recent call last): ... ValueError: Unknown backend ...!
Parameters: backend (string) – Name of the backend to use, must be in pygencad.backends. Raises: ValueError if the provided name isn’t in pygencad.backends Returns: Layer class for the indicated backend.
