Thanks, Taco. Good to know. Although it's not what I wanted to hear, of course...

I was thinking using mp to draw the combination could be solution, but unfortunately I don't know metafun yet.

If my understanding of https://source.contextgarden.net/node-rul.mkiv is correct, it should be possible to build upon the defintion of rules:under:dots (l. 327) Any hints how I could get this started?

Yes, that is the right part to get started with. You could just copy the whole \startuseMPgraphic and rename it for editing (to let’s say rules:under:bardots), then do \definebar[underbardot] [undergraphic][mp=rules:under:bardots] and play with the mp until you are happy with the output. But the problem is that you have to create an “underbardot" that contains both the bar and the dots, to fix the non-nesting problem. It is then quite hard to get that definition to align properly with any enclosing “underbar” (I tried something like that a while ago and basically gave up. I did not want to spend a whole of time on it so I just told the client “computer says no").

Another question: what do you mean with a dy-shift version?

Nested bars have a parameter ‘dy’ which controls the vertical shifts needed to make sure that they do not overlap. Text backgrounds do not have that option at all.

Hi,

for a current project I’ll need different variants of underbars.

- A normal underbar - A dotted underbar - A combination of both

Is there a way to combine them? I was hoping to have the dotted variant above the normal bar.

I would like to have this type of “complete” bar nesting as well.

As it stands, you can nest \underbars inside \underbars and \overstrikes inside \overstrikes and \overbars inside \overbars, but no other combinations work. Interoperability between these (as well as \underdot, \underdash, \underrandom ...) would be really cool.

Either with \xxxxbar or a nestable dy-shift version of textbackgrounds would be really handy sometimes. :)

This is not working

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \starttext

\underbar{asdf}

\underdot{asdf}

\underbar{\underdot{asdf}}

\stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Best, Denis
