Convert VimWiki to HTML (markdown, mediawiki)

vimwiki2html.md

With this wiki2html.sh bash script and pandoc program, you can convert markdown to html.

Usage: In the vim list section of the .vimrcfile, include options:

let g:vimwiki_list = [{'path': ‘your_wiki_place',
  \ 'path_html': ‘wiki_html_location’,
  \ 'syntax': 'markdown',
  \ 'ext': '.md',
  \ 'custom_wiki2html': ‘link to the custom converter, i.e. wiki2html.sh'}]

If you want to use this converter for temporary wikis then add these to .vimrc:

  autocmd FileType vimwiki call SetMarkdownOptions()

  function! SetMarkdownOptions()
    call VimwikiSet('syntax', 'markdown')
    call VimwikiSet('custom_wiki2html', 'wiki2html.sh')
  endfunction

:VimwikiAll2HTML and <leader>wh work well.

    MATH=""

# >&2 echo "MATH: $MATH"

sed -r 's/(\[.+\])\(([^)]+)\)/\1(\2.html)/g' <"$INPUT" | pandoc $MATH -s -f $SYNTAX -t html -c $CSSFILENAME | sed -r 's/<li>(.*)\[ \]/<li class="todo done0">\1/g; s/<li>(.*)\[X\]/<li class="todo done4">\1/g' >"$OUTPUT.html"

Just a comment, sed does not have an option -r on Mac (it has NetBSD utilities?). The extended regexps are turned on by -E. Also it seems the Linux version of sed may work with all variants -E, -r, --regexp-extended.
