Lua: DefinitionList contents

Lua: DefinitionList contents

I need to be sure what DefinitionList.content looks like in Lua filters,
because the documentation does not tell.

I *think* that it is a list of lists where each sublist has two items

1.  A list of inlines (term)
2.  A list of lists of blocks (definitions)

Is that correct?

It may not be how they are represented in Haskell, but it would be very
helpful if in Lua each definition list item was an object where the term
and definitions were accessible both numerically and by name so that
`item[1] == item.term` and `item[2] == item.definitions`. I for one have it
easier to think about them by name.

The use case is to convert a table that has grown out of itself into a
definition list of definition lists so that

``````markdown
|   | a | b | c
|---|---|---|---
| A | 1 | 2 | 3
| B | 4 | 5 | 6
| C | 7 | 8 | 9
``````

becomes

``````markdown
A

~   a

    ~   1

    b

    ~   2

    c

    ~   3

B

~   a

    ~   4

    b

    ~   5

    c

    ~   6

C

~   a

    ~   7

    b

    ~   8

    c

    ~   9
``````

except that in reality there are six rather wide columns and about a dozen
rows in the table.

I'm mostly clear about how to do it except that I'm not sure how definition
lists are structured.

Fully agree. The newest HsLua version is, I believe, flexible enough to
accommodate this change in a backwards-compatible fashion. Please open
an issue on GitHub so we won't lose track.
