How does this handle tabs vs spaces? I looked the post, the repo and the issues page and I didn't find anything. I'm specially concerned about not seeing this in the options of the API, since there are strong opinions on both sides.
For tabs/spaces and semicolons I'm considering if we should support those options. We need to figure out the goal of the project: is it to converge on generally a single format, or is it to provide formatting options for a few large groups of people that have different opinions. There are issues on the project discussing this right now.
Perhaps stick to just one, as seems to be the case right now (whichever it is), and mention in the documentation that those wanting the other option are free to e.g. write a patch/fork on GitHub/postprocessor/etc., with the understanding that such support will eventually get merged in iff it's actively maintained for some amount of time, its author/maintainer is active in general development and maintenance for the project, and there's significant community adoption of such a patch.
Whilst not perfect, this sort of approach might better determine who actually cares enough about this to offset the community-splitting effects of allowing both; compared to a general accumulation of online grumbling.
