Negative vs minus #31

Closed kelvinsjk closed 9 months ago

kelvinsjk commented 11 months ago

The typesetting of negative and minus signs seems to be off after = signs

PS: Thanks for the awesome library

If you want unary operators to have different spacing than binary operators, I'll think you'll have to raise that issue elsewhere.

Maybe at the MathML-Core issue tracker.

Ah, so the issue is with mathml. Thanks for the insight!

I think this is an issue with Temml, not MathML. Temml should emit form="prefix" for unary operators. For now I'm post-processing the Temml output with this regex:

.replaceAll(
  /(<\/mo>(?:<\/mrow>)?(?:<mrow>)?)<mo>(−|-|\+)<\/mo>/g,
  "$1<mo form=\"prefix\">$2<\/mo>"
)

I think this is an issue with Temml ... Temml should emit form="prefix" for unary operators.

@mk12 You are correct! Thank you for pointing that out. I'll have it fixed sometime later this week.

Also happens inside brackets ((-x)) and after word operators (\exp -x).

Fixed by release v0.10.20.
