OK, I played around a little bit with sample.lua and have the following
understanding:
(1) pandoc handles normal template usage in combination with sample.lua, I
only have to set --template=... on the commandline. Everything is fine.
(2) Despite specifying --toc on the commandline, _no_ table of contents is
produced with sample.lua! It seems, that pandoc internally sets the content
for the table of contents to the metadata variable toc. In fact, if I add
some arbitrary text to the metadata variable toc, e.g. in a yaml block,
then a table of contents is printed with this text through my template. It
does not matter, if --toc is used or not.
Question: How can I set the metadata variable toc in sample.lua? (I guess,
I would have to create the toc myself in sample.lua). I tied to modify
metadata in function Doc, but it didn't work.
(3) Section numbering does not work with sample.lua. How can I get the
commandline arguments --number-sections and --number-offset=N in
sample.lua? I guess, I would also have to do the section numbering myself
in sample.lua.
(4) --sections-divs does not work in sample.lua. If I could read the
commandline argument --section-divs in sample.lua, I could write the
opening tag in function Header. BUT: where and how could I create
the closing tag? Maybe I would have to put a closing tag right
before the next opening tag in every call to function Header at the same or
lower level and add the last closing tag in function Doc to the body. Or is
there a better way?
Thanks in advance for every help!
Regards
Karl
