Github Actions CI

[SagiPolaczek]

Hey Fusers 👋 🔬

We now support Github actions CI - meaning each PR will have to pass additional tests focusing on style and format to ensure uniform code style in Fuse.
For your convenience here is a quick recap:

We use the following three tools: black, flake8 and mypy.

black

Enforces code style and format. We use the standard style guideline with a minor change: we restrict lines' lengths to be 120 (instead of 88).

To check if file / directory suit the code style guidelines and see the changes black will make:

black <path> --check --diff --color

To apply the changes:

black <path>

flake8

Checks code style (similar to black) and detects various issues not covered by black.
usage:

flake8 <path>

TIP : If flake8 gives you a lot of error messages, use black's formatter might solve most of them. The rest should be done manually.

mypy

Enforces the usage of type annotations for functions input arguments and return values only, but not the correctness of them. For examples:

def this_func_returns_int(number): # BAD
    ...
def this_func_returns_int(number: int): # BAD
    ...
def this_func_returns_int(number: int) -> int: # GOOD
    ...
def this_func_returns_int(number: str) -> str: # Will pass, but not so good
    ...

You are welcome to ask questions and raise issues in the discussion thread below.
Happy Fusing 🔬
