single_line_tuples: space after comma?

[justvanrossum]

When using single_line_tuples, tuples are formatted like (123, 456). GlyphsApp, however, doesn't output the space after the comma and formats as (123,456).

openstep-plist/src/openstep_plist/writer.pyx

Lines 469 to 471 in 61dc6ac

	if self.single_line_tuples:
	dest.push_back(c' ')
	count += 1

Do we want to (optionally) format like GlyphsApp? I'll gladly PR this.

Do we want to:

1. Not bother, the openstep_plist package's goal does not include formatting like GlyphsApp
2. Never output the space
3. Optionally don't output the space

My preference would the the second option.

There are some additional GlyphsApp deviations that I'd like to address:

• empty objects being spread over two lines instead of the single-line () and {}
• binary data formatting

FWIW, I have fixes for all of these in this branch (which includes #35):
