How to automatically put bam modifiers in pug during build, depending on the page being built?

Question

Pug

There is a page. It includes a block. The same block is included on the second page. I want so that I don't have to create two different files of the same block, and somehow pug put different modifiers on the same block on different pages.

Conditionally: on one page becomes on another:

<div class='block'>


<div class='block block_mobile'>


<div class='block block_desktop'>

Answer 1

I think a mixin would be perfect for this instead of an include.
