Hello,
I was looking at the implementation for =org-md-item=, in ox-md.el, and I'm
wondering how indentation logic for nested lists works. Specifically, I was
looking at the following code:
#+BEGIN_SRC elisp
(concat bullet
(make-string (- 4 (length bullet)) ? )
(pcase (org-element-property :checkbox item)
(`on "[X] ")
(`trans "[-] ")
(`off "[ ] "))
(let ((tag (org-element-property :tag item)))
(and tag (format "**%s:** "(org-export-data tag info))))
(and contents
(org-trim (replace-regexp-in-string "^" " " contents))))
#+END_SRC
and I'm wondering why it's adding indentation in front of the bullet. Naively, I
would expect the result of this snippet, for an unordered list to be something
like:
=- [item contents]=
That is, it concatenate the bullet, then three spaces (4 - length of bullet),
then another four spaces, then the contents of the item. Instead, what I see is
a four-space indent, followed by the bullet and its padding, followed by the
item contents:
= - [item contents]=
This is the correct result, but I don't see how the code from ox-md.el produces
that result.
The reason I'm asking is because I have similar logic in the org-mode exporter
I'm writing for PMWiki markup:
https://github.com/quanticle/ox-pmwiki/blob/master/ox-pmwiki.el#L214
and I would like to change the logic so that instead of indenting with spaces,
it repeats the list marker (** for a second level nested list, *** for 3 levels
of nesting, etc).
Thanks,
Rohit Patnaik

The code makes use of the CONTENTS.
If you have nested lists
- item
- sub-item
- sub-sub-item
"sub-sub-item" transcoder will receive CONTENTS="sub-sub-item" and return
- sub-sub-item
then, "sub-item" transcoder will receive CONTENTS="sub-item" + output of
nested transcoder -
CONTENTS=
sub-item
- sub-sub-item
and add 4 spaces to each line, except first:
- sub-item
- sub-sub-item
then, item transcoder will receive the result of the two nested
transcoders:
CONTENTS=
item
- sub-item
- sub-sub-item
yielding
- item
- sub-item
- sub-sub-item
Hope, it clarifies things.
