Thanks for the help. I now updated the function `org-mw-item` to:
(defun org-mw-item (item contents info)
"Transcode ITEM element into Mediawiki format.
CONTENTS is the item contents. INFO is a plist used as
a communication channel."
(let* ((type (org-element-property :type (org-export-get-parent item)))
(bullet (if (eq type 'ordered) ?# ?*))
(the-item (org-trim contents))
(level (- (/
(length (org-element-map (org-element-lineage
item) 'plain-list
#'identity info)) 2) 3)))
(progn
(org-element-put-property item :post-blank 0)
(format "%s %s" (make-string level bullet) the-item
With this change the following org input:
```
* A section
Here is a list of things
- An item
- Another item
- A subitem
- Another subitem
- Back to first
```
Is output as:
```
= A section =
Here is a list of things
* An item
* Another item
** A subitem
** Another subitem
* Back to first
```
This is close to the required result though there is still a redundant
empty line before "A subitem". How can I get rid of it?
I also have no idea why I had to do the expression $level/2-3$ to get
the correct number of asterisks.
Another complication that I am currently ignoring is how to nest
and lists. But that's ok for now.
Thanks again!
