annotated equations

annotated equations

[Henning Hraban Ramm via ntg-context]

Here’s an interesting example for annotated equations, done with LaTeX/TikZ:
https://mastodon.social/@sibin/109349703357749846

I guess something similar is possible with node anchors in ConTeXt/MetaPost?

Mikael and I played plenty with annotating formulas as part of all this 
math stuff (part of exploring interference with spacing which is 
something we don't want cq. bother users with); for inline, display and 
matrices

but as usual it's demand driven so it is pending 'documenting' and 
'interface improvements' ... it's not like users are screaming for these 
features and there are no projects that drive them so "yes, it's there, 
but you need to check the examples (in the source)"

the priorities are currently: math tweaks (+ fixing some fonts), new 
math manual, additional trickery, mixed with stimulating metafun

(attached a quick and dirty copy of one of our many todo docs)

Marei told me this is nothing individual but from this package:
https://ctan.org/pkg/annotate-equations
It’s mostly TikZ and could also work with ConTeXt.

Of course. I don’t need it, hardly use formulae at all, but I found it 
interesting.

That’s funny, maybe there’s an intentional connection.

Yes, this is possible using node anchors and \hpos etc. The interface is slightly cumbersome, mainly because you have to make sure that anchors are unique. 

I sometimes use such constructs in my presentations, but not often enough to build a nice interface as the latex package provides.

eventually there will be something as part of the math upsate (we also 
have some stuff for matrices already) but only documenting can make if 
final (as then we check consistency); the problem is not the interface 
but to *not* mess up the math spacing that we want to be 'perfect' if 
such features are used without the need to interfere
