formatting a R6 object with roxygen2 documentation fails

[maarten-k]

formatting a R6 object with roxygen2 documentation fails with:

tidying /tmp/r6.R
Error in base::parse(text = code, keep.source = FALSE) : 
  <text>:7:1: unexpected symbol
6: invisible(".BeGiN_TiDy_IdEnTiFiEr_HaHaHa#' @field name First or full name of the person..HaHaHa_EnD_TiDy_IdEnTiFiEr")
7: name

It would be nice to have this formated in an nice way.

code to reproduce:

code of the R6 is taken from https://www.tidyverse.org/blog/2019/11/roxygen2-7-0-0/

cat > /tmp/r6.R << 'EOF'
#' R6 Class representing a person
#'
#' A person has a name and a hair color.
Person <- R6::R6Class("Person",
  public = list(
    #' @field name First or full name of the person.
    name = NULL,

    #' @field hair Hair color of the person.
    hair = NULL,

    #' @description
    #' Create a new person object.
    #' @param name Name.
    #' @param hair Hair color.
    #' @return A new `Person` object.
    initialize = function(name = NA, hair = NA) {
      self$name <- name
      self$hair <- hair
      self$greet()
    },

    #' @description
    #' Change hair color.
    #' @param val New hair color.
    #' @examples
    #' P <- Person("Ann", "black")
    #' P$hair
    #' P$set_hair("red")
    #' P$hair
    set_hair = function(val) {
      self$hair <- val
    },

    #' @description
    #' Say hi.
    greet = function() {
      cat(paste0("Hello, my name is ", self$name, ".\n"))
    }
  )
)
EOF
Rscript -e 'formatR::tidy_file("/tmp/r6.R")'
