tikz diagrams #488

Closed EgbertRijke closed 11 years ago

EgbertRijke commented 11 years ago

Would it be worthwile to convert all the xy-diagrams to tikzcd-diagrams? Most of them look ok currently but the long exact sequences could be typeset much better, as in this tex.stackexchange answer for example.

What's better about a curvy arrow than a straight one?

EgbertRijke commented 11 years ago

They have better control over where the arrow points to with the [in=..,out=..] option. Sometimes our diagonal arrows touch the next one, sometimes not. It seems to be not very consistent (or consistent in the wrong way maybe) to me.

I don't know what you're talking about, can you refer to a specific diagram? On Oct 15, 2013 12:12 PM, "EgbertRijke" notifications@github.com wrote:

The diagrams in section 8.5 on page 269 of hott-online.

They look fine to me; what's the problem again?

andrejbauer commented 11 years ago

I think converting diagrams from (the very standard) xypic to the not-so-standard tikzcd is a lot of work for very little benefit. Let's not do this.

andrejbauer commented 11 years ago

Is there a diagram which you think could be massively improved?

mikeshulman commented 11 years ago

No discussion has happened on this issue for a month, so I'm closing it. @EgbertRijke, if you want to explain further what you think could be improved, feel free to reopen.
