I am trying to make my own customized writer for LaTeX. In this writer, I’d 
like to be able to handle itemizations with nesting and write those 
properly to LaTeX’s itemize environment. Here’s what I have so far:
Writer file custom_writer.lua 

function Header(lev, s, attr)
    level_sequences = {
        "section",
        "subsection",
        "subsubsection",
        "subsubsubsection"
    }
    return string.format("\\%s{%s}", level_sequences[lev], s)
end

function Blocksep()
    return "\n\n"
end

function Para(s)
    return s.."\n\n"
end

function Str(s)
    return s
end

function Space()
    return " "
end

function BulletList(items)
    print("entering BulletList function")
    for i, item in pairs(items) do
        print(i, item)
    end
    return " "
end

function Plain(s)
    return s
end

function Doc(body, metadata, variables) 
    return body
end

Markdown file test.md 

# A section

## A subsection

- An item
    - A subitem
    - A subitem
- An item

Question 

Note the print statements in the BulletList function of my Lua file. To my 
surprise, when I compile using pandoc test.md -t custom_writer.lua -o 
test.tex I get the following output:

entering BulletList function
1    A subitem
2    A subitem
entering BulletList function
1    An item


2    An item
`

There are two things that strike me here:

   - The nested list appears to be processed first, before the outer list. 
   This seems counter-intuitive to me. I can’t think of an algorithm which 
   would result in the correct LaTeX nesting if it goes inner to outer. Why 
   does this occur? Can I get it so that it goes the other way round? 
   - Two blank lines are printed out between 1 An item and 2 An item. Where 
   do these come from? I haven’t specified them anywhere in my Lua file.
