Changes in 0.1.3 break tutorial.helpers package

[davidkane9]

1) This change in version 0.1.3

• Unlabeled chunks will now be labeled as unnamed-chunk-n, with n incrementing.

breaks my tutorial.helpers package. Sadly, I did not have any test cases which would catch this change. Lesson: test more thoroughly!

2) Is there any way to remove this behavior? That would be very convenient for me!

3) Comment: This seems like a very bad default behavior to me. The purpose of parsermd should be to parsermd documents. It should not, quietly or otherwise, add any text to a document. If a code chunk has no label, it should be left without a label.

UPDATE: I was able to use this hack to solve my problem. So no need to fix this just for me.

  # Parse Rmd of file path

  rmd <- parsermd::parse_rmd(file_path)

  tbl <- tibble::as_tibble(rmd)

  # parsermd 0.1.3 created a difficult to diagnose bug for me. It labels any
  # unlabelled R code chunk as "unnamed-chunk-n" with "n" incrementing. That is
  # very bad! You should not add labels which do not exist. So, I do a total
  # hack to just remove those labels from the final document. Of course, this
  # will hose any user who actually has a code chunk whose label matches
  # "unnamed-chunk-n" wiuth "n" as any integer, but what are you going to do?
  # This hack was easier (?) than trying to work directly with objects of class
  # "rmd_ast" "list"

  for(i in seq_len(nrow(tbl))){
    if(grepl("^unnamed-chunk-\\d+$", tbl[i, "label"])){

      # Once we get the correct row, we do two things. First, we remove the
      # label from the tibble. Not sure why this is necessary. Is the label
      # really used later? Second, we need to change the ast itself.

      tbl$label[i] <- NA
      new_ast <- purrr::map(tbl$ast[i], change_chunk_function, "name", "")
      tbl$ast[i] <- new_ast
    }
  }

If anyone has comments on a better way to do this, I would be interested.
