Crash when adding nested lists inside instructor's notes

[LourensVeen]

I'm writing some inline instructor's notes, and inside of them I have a nested list, like this:

::::::::::::::::::::::::::::::::::::: instructor                                
- item
- another item
    - nested item
    - another nested item
::::::::::::::::::::::::::::::::::::::::::::::::

When I then run sandpaper on the project, it says:

 sandpaper::build_lesson(".", preview = FALSE, quiet = FALSE)
── Validating Fenced Divs ───────────────────────────────────────────────────────────────────
Error in .x[[1]] : subscript out of bounds

Markdown supports nested lists, and the syntax is correct, so if this is a limitation I'd expect at least a better error message. Single-level lists work fine at least.

Thank you for reporting the bug with an example and the error message!

Solution

The solution for now is to make sure you have newlines surrounding your fences:

::::::::::::::::::::::::::::::::::::: instructor
                                
- item
- another item
    - nested item
    - another nested item

::::::::::::::::::::::::::::::::::::::::::::::::

Source of problem

This is a symptom of carpentries/pegboard#84. Effectively, the markdown parser used for pre-flight validation thinks that the closing fence is part of that last list item.

I will try to get a fix to {pegboard} soon that will propagate since that is valid pandoc syntax.

Hi, thanks for the response! So that's the problem! I ended up doing

::::::::::::::::::::::::::::::::::::: instructor
- item
- another item
- --- --- **#** nested item
- --- --- **#** another nested item
::::::::::::::::::::::::::::::::::::::::::::::::

which also works, but makes me feel a bit ashamed to write it :-). I'll go put in some newlines instead, thanks!
