"""Extension to execute code outside the Python shell window.
|
||
|
|
|
||
|
|
This adds the following commands:
|
||
|
|
|
||
|
|
- Check module does a full syntax check of the current module.
|
||
|
|
It also runs the tabnanny to catch any inconsistent tabs.
|
||
|
|
|
||
|
|
- Run module executes the module's code in the __main__ namespace. The window
|
||
|
|
must have been saved previously. The module is added to sys.modules, and is
|
||
|
|
also added to the __main__ namespace.
|
||
|
|
|
||
|
|
XXX GvR Redesign this interface (yet again) as follows:
|
||
|
|
|
||
|
|
- Present a dialog box for ``Run Module''
|
||
|
|
|
||
|
|
- Allow specify command line arguments in the dialog box
