use_tabs=True does not work for lists and dictionaries

We use_tabs for indentation but continuation_indent_width still uses spaces instead of tabs for lists and dictionaries that are split over multiple lines. If required there should be a separate knob for this which allows setting of tabs vs spaces for lists and dictionaries

@gwelymernans, there are 2 basic school of thoughts (amongst us tabbers=tab users) for continuation alignment

• Tab only (for both indentation and alignment) In this case whenever continuing on a long line, there will be an additional tab like in the 1st screenshot of @gregwym
• Tab and space indentation (tab for code indentation and tab+spaces for alignment) In this case the tab indentation used for the primary line is retained and further indentation is done through spaces. This keeps the code aligned regardless of the tab to space display being used on a particular display/IDE and works well for those who use it.

Currently yapf does a very unexpected switchover back to pure spaces for continuation indentation which is probably completely invalid for any tabber.

If yapf has to truly cater to tab users, it will probably have to have a flag for those of us in the 2nd school of mixed indentation

hope I have helped

Thanks for not starting a ‘holy war’ on this 👍 . Ideally, though this may vary even amongst us ‘tabs’ people, I think I would want the continuation indent to be additional to the indent at which the code is at right now. so CONTINUATION_INDENT=1 should result in the code below Eg below

def a():
	really_long_dictionary_name = {
		first_really_long_key: 1,
		second_really_long_key: 2,
	}
