jade/pug Is it possible to use variables on include statement?

Question

I'm developing nodejs application and I have issue with include statement. It works when I use it like this:

include ../mixins/root.pug

...but is it possible to use variables on include?

None of these work:

include #{process.env.MIXINS_PATH}/root.pug
include !{process.env.MIXINS_PATH}/root.pug
include `${process.env.MIXINS_PATH}/root.pug`

Result is this:

Error: ENOENT: no such file or directory

Answer 1

Dynamic includes are not supported:

We don't support "Dynamic Include". There are lots of issues people have opened about this. It's really complex to implement and not actually nearly as useful as people think it would be.
