"""Extension to execute code outside the Python shell window.
|
|
|
|
This adds two commands (to the Edit menu, until there's a separate
|
|
Python menu):
|
|
|
|
- Run module (F5) is equivalent to either import or reload of the
|
|
current module. The window must have been saved previously. The
|
|
module only gets added to sys.modules, it doesn't get added to
|
|
anyone's namespace; you can import it in the shell if you need to. If
|
|
this generates any output to sys.stdout or sys.stderr, a new output
|
|
window is created to display that output. The two streams are
|
|
distinguished by their text color.
|
|
|
|
- Debug module (Control-F5) does the same but executes the module's
|
|
code in the debugger.
|
|
|
|
When an unhandled exception occurs in Run module, the stack viewer is
|
|
popped up. This is not done in Debug module, because you've already
|
|
had an opportunity to view the stack. In either case, the variables
|
|
sys.last_type, sys.last_value, sys.last_traceback are set to the
|
|
exception info.
