Dynamic R code not running properly

[danielvartan]

Hi there!

I'm having rendering issues when using dynamic R code in a @format tag. Apparently it came up with the latest versions.

Example (see the R file here):

#'
#' @format A [`tibble`][dplyr::tibble()] with `r ncol(mctq::shift_mctq)`
#'   columns and `r nrow(mctq::shift_mctq)` rows:
#'

Rd Render:

I can't reproduce this:

Your session info does not include the versions of roxygen2 or the version of the package you are documenting. I used your main branch and roxygen2 7.1.2.

Hi @gaborcsardi !

You couldn't reproduce because I already fixed the mctq main branch (I removed the dynamic code).

Please try using the package at this point:

https://github.com/ropensci/mctq/tree/472922d20928efc6bd1c1f5dcca0fafcd49b9e0e

I'm using roxygen2 7.1.2 too.

[gaborcsardi]

Got it, thanks! Simple reprex:

roxygen2:::markdown("X\n  `r (1+1)`\n")
#> [1] "X\n2)`"

It seems like a workaround is to avoid indentation:

roxygen2:::markdown("X\n`r (1+1)`\n")
#> [1] "X\n2"

This looks like it's another bug with how commonmark records source references.
