code_gen.rs should take into account existing code preferences

[charliermarsh]

It'd be great to generate code that's aware of existing indentation and quotation preferences.

I just ran into this as well with E712 on the following example code:

image = {"primary": 23}

if image["primary"] == True:
  print("hello!")

Running ruff 0.0.196 on this results in:

image = {"primary": 23}

if image['primary'] is True:
  print("hello!")

If the intent is to have ruff work with Black out of the box then it should default to double quotes - although obviously it would be nice to detect the quoting style before the fix as well.

Yeah agreed. It actually used to double-quote, but it required forking RustPython. I’ll look into it again and see if we can at least preserve double quotes, since it’d go a long way towards compatibility.

(Also: thank you for the clear example + version number etc.)

I'm gonna ship some improvements to this today.
