How to negate / escape a show rule?

[Maxwell]

The answer of @bluss is pretty well, but if u dont’t want to call the function nonunderline() every where, try:

#show link: it => {
  let b = it.body.text
  if b.at(-1) == "-" {
    show underline: u => u.body
    link(it.dest, b.slice(0,-1))}
  else {
    underline(it)}}

#link("https://www.a.com")[Web A]
#link("https://www.b.com")[Web B-]

As for general show/set rule escaping, see:

How can I bypass set/show rules to revert to the default?

No. Currently we can’t revoke set/show rules in Typst. But it’s a planned feature: Related issue, Typst Roadmap If you want to apply two different styles to the same element, you can encapsulate the element with specific styles into a function, for example: #let styled-text(..args) = { set text(font: "Buenard") text(..args) } #styled-text("123", size: 10pt) But I guess there’s probably no way to encapsulate the default style into a function, especially when you applied a show rule.
