I think one of the great benefits of Black is that it is opinionated. Giving folks the option to select the type of indentation blunts the benefits. If you have a huge code base which mixes tabs and spaces it’s going to be hard to diff and merge code (or even reuse code snippets).

The point of black is that you run it on the same codebase with the same parameters.

Prettier works the exact same way and does have --use-tabs as a parameter. Nobody died. No codebase ended up with mixed tabs and spaces from it. Codebases either do --use-tabs or don't.

Like I said, there are a lot of reasons to allow for this. For one thing, tabs are an accessibility feature, but also it's impossible to use Black in an environment that prefers tabs.

Whereas there's no such thing as "an environment that prefers exactly two spaces after every comma inside tuples", thus you don't need an option for this.

>Yet the more options Prettier has, the further from the above goal it gets. The debates over styles just turn into debates over which Prettier options to use. Formatting wars break out with renewed vigour: “Which option values are better? Why? Did we make the right choices?”

>And it’s not the only cost options have. To learn more about their downsides, see the issue about resisting adding configuration, which has more s than any option request issue.

>So why are there any options at all?

>A few were added during Prettier’s infancy to make it take off at all. >A couple were added after “great demand.” >Some were added for compatibility reasons.

Reading this doc it feels like the Prettier team is saying options like tabs/spaces were only added early on to get initial adoption, if it were up to them now there would be far less options to configure at all.

The options in question are some of the more.. fancy ones, and the "history" in question is things such as cross-compatibility with ESLint. Certainly not "tab support". (And I've contributed to Prettier a great deal, FWIW)

Yes, that's right.
