Or even:
@hidden
def init(self): ...
@main
def mymainfunc():
...
The first of those probably wants some metaclass support to make it work
cleanly, but here's a sample implementation for the second one:
import sys, atexit
def main(f):
"""Decorator for main function"""
def runner():
sys.exit(f())
if f.func_globals['__name__']=='__main__':
atexit.register(runner)
return f
print "define mymainfunc"
@main
def mymainfunc(args=sys.argv):
print "Got args", args
return 3
print "end of script"
If you have multiple functions marked as main that will run them in
reverse order, so it might be better to put them on a list and use a
single runner to clear the list. Also, I have no idea what happens to
the exit code if you use this decorator more than once.
BTW, should anyone be wondering, you can still use atexit inside a
function called from atexit and any registered functions are then called
when the first one returns.
