Introduce class vertical

[lorenzwalthert]

To avoid

style_text(...) %>%
  cat(sep = "\n")

And simply write

style_text(...)

[lorenzwalthert]

There is one obstacle: The tests won't pass anymore since the output of style_text is not the same as the reference with regard to the attributes. However, when written to the file, the text is identical. test_collection() uses utf8::transform_lines_enc(), which test whether the input and the transformed output is identical via identical(), which seems a bit too strict for our case. It seems to me that all.equal(..., check.attributes = FALSE) would be more accurate in our situation. Should we adapt test_collection to not rely on utf8::transform_lines_enc() for the comparison?

@krlmlr can you advise on that?

[krlmlr]

Can you insert an unclass() somewhere before checking equality or before calling transform_...()?
