Closes #75.

to do

  • clean up
  • add regression tests with inputs from Too many spaces #75
  • for posterity, explain why this fixes everything

@georgefst georgefst marked this pull request as draft March 27, 2022 23:22
Rather than stripping all whitespace after parsing, then adding it back between every expression, we now mostly keep whatever whitespace existed in the input.

This partially reverts 20d8a2d. With the other changes in that commit, we had assumed that this sledgehammer approach to whitespace was virtually necessary. This commit shows that, with a bit more care, that needn't be the case. We add some tests for inputs on which we had regressed to unpleasantly whitespace-heavy output.
With the whitespace handling changes in the previous commit, it became far simpler, and ultimately unnecessary. We inline the one non-trivial part in to `prettyExpr`.

Great, thanks for working on this!

This looks good to me.

You want to add a CHANGELOG and make a release?

I'm inclined to wait a few days, to see if anyone has any concerns (#75 (comment)). If there's no response, I'll release on the weekend.

Actually, I'll do it now. I don't know if I'll have time on the weekend.
