How to disable html escaping in string interpolations?

Hey there,

I have a custom context with a function that returns a string with html in it: cite(key).

When I use it in a paragraph, the returned output is always escaped - how can I disable that?

p This is some text #{cite :reference21 }, which goes on here

# currently returns
"This is some text <span>(Reference, 21)</span>, which goes on here"

# wanted
"This is some text (Reference, 21), which goes on here"

Usually this is done with ==, but I tried everything I could find - and it does not work.

What am I missing?

Thanks and all the best!

Have you tried double braces? I think it can be done like this:

p This is some text #{{cite(:reference21)}}, which goes on here

Dear @r7kamura, thanks a lot, that works like a charm!

Is this already documented somewhere? Otherwise I would be happy to add it.

Yes, it is described in the Text Interpolation section in README:

Use standard Ruby interpolation. The text will be html escaped by default, but you can avoid escaping by using double braces.

body
  h1 Welcome #{current_user.name} to the show.
  | Unescaped #{{content}} is also possible.

Actually, I didn't find out about this feature by reading this section, but I learned about it when I was developing slimi, yet another implementation of slim. Anyway, I'm glad it helped 😃
