How to execute a file outside module's namespace?

[Slawomir Nowaczyk]

Hello,

Let's say I have a module "emacs", defining function eexecfile(file):

def eexecfile(file):
# do other stuff
execfile(file,globals())
# do other stuff

Now, assume I have file test.py containing an assignment "x=1"

If I run python and do:

import emacs
emacs.eexecfile("test.py")
print emacs.x # works, x was put in module namespace
print x # doesn't work, x is not defined in main script namespace

What is the best way to make "print x" work? Using the following:

import __main__
def eexecfile(file):
# do other stuff
execfile(file, __main__.__dict__)
# do other stuff

seems to work, but it gives me a slightly uneasy feeling. Is this the
right way?

"from emacs import x" will expose x to the current namespace

#"from emacs import x" will expose x to the current namespace

True... but I do not know in advance what is the contents of test.py
file -- it could be "a=1" :) Sure, I could go over emacs.__dict__ and
expose everything except eexecfile, but that's even less satisfying
than the solution above.

Anyway, thanks for the suggestion.

emacs.py:

main:
