Remove console interface
The console interface is very nice and could reduce the "boilerplate" to 3 lines:
def main(arg1, arg2):
print(arg1, arg2)
if __name__ == '__main__':
from sys import argv
main(*argv[1:])
However, it has three big disadvantages:
- no auto-serialization (it's just strings)
- it's still code that a high-level user shouldn't care about
- starting a process in an interpreted language like Python/NodeJS does come with an overhead
Now, of course the serialization bit could be handled with two more lines:
def main(arg1, arg2):
print(arg1, arg2)
if __name__ == '__main__':
from sys import argv
from json import loads
main(*map(loads, argv[1:]))
However, the number of characters that can be processed via the CLI has a limit (see e.g. https://serverfault.com/questions/163371/linux-command-line-character-limit, https://www.in-ulm.de/~mascheck/various/argmax/) which is why I think we shouldn't recommend to use the console interface.
@microservices/omg-maintainers I am in favour of dropping the console interface, as it's restrictive, and always has overhead in terms of starting up.
I'm fine with dropping it, we can always add it back in future if it is a desired feature.
