[Twisted-Python] Sending arguments to application
Hi! I using the variant "twistd -y foo.py" and I would like to be able to send arguments to foo.py in the same command. The preferable way would be something like "twistd -y foo.py arg1 arg2" But that doesn't work, twistd complains. If it can be done some other way, how ? -- Roland
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 That's just not how twistd -y works. The argument is supposed to be something called a "TAC" file, which is just a config file that happens to have Python syntax. In other words, you put your arguments inside it. You can name the file .py if you want to, but conceptually it's still supposed to be a config file. If you want another way of configuring your application, you need to provide your own main entry point, and use something (probably twisted.python.usage) to process the command-line arguments.
