Hello
I submitted this earlier today, but I was not clear enough, so I am
posting it again.
I am running a simulator written in python. The simulator has a small
TextView (actually a SourceView) widget which lets the user writes
scripts, and when they are satisfied they can execute that script to
get results. For arguments sake, we write a simple script and save it
as A.py and we import it and execute it more or less like so.
import A
#assume there is a function called test() in module A
A.test()
Then the user modifies the contents of A.py and saves it again (to
A.py) now all we have to do is the following
if 'A' in dir():
reload(A)
else:
import A
A.test()
But since the user chooses the file name, and not me, the programmer,
the module names will vary. Let's assume the module names are loaded
and stored in the list module_names, and we iterate over them, and
pass them as arguments to a function to import or reload each model as
appropriate
def import_or_reload(module_name):
if module_name in sys.modules:
#somehow reload
else:
#somehow import
does anyone know how to deal with the reload and import as they both
present problems since module_name is a string, and to reload
something along the lines of the below must be executed
exec 'reload(%s)'%module_name
and then we also have to deal with the scope issue since the loaded
module will be local and not global. I can execute something like so
exec 'global %s'%module_name
but that does not work very well with exec
any suggestions?
Cheers
Peyman
