Is it possible to extend this library for other targets like HTML and LaTex?

I would like to print source code on documents and website too, where String is not sufficient.

I don't know how it would be very different. You can use this to generate HTML or Latex strings. I use it to generate python and C code.

What do you have in mind that would need to be added? If you mean some special utilities for making tags, or similar, that we would not put in the main code, but you could imagine sending a PR making a paiges-html module or something similar.
