Snippets instead of full documents?

[13protons]

There are two features of MMD I'm trying to get to in the node module - snippets and metakeys.

From the MMD docs on , it's these functions:

multimarkdown -s, multimarkdown --snippet
multimarkdown -m, multimarkdown --metadata-keys

My goal is to get an html snippet back with a json object containing the document's metadata keys so I can pass that all on to some template logic.

Any suggestions on how to accomplish this?

Hi @alanguir,

Which version of MMD has those options? I don't see those flags in the version I am currently using for node-multimarkdown. Here is the source I am looking at for the usage of the command-line tool:

static void printUsage() {
    printf("Usage:\
  multimarkdown [OPTION...] [FILE...]\n\
\n\
Help Options:\n\
  -h, --help              Show help options\n\
\n\
Application Options:\n\
  -v, --version           print version and exit\n\
  -o, --output=FILE       send output to FILE (default is stdout)\n\
  -t, --to=FORMAT         convert to FORMAT (default is html)\n\
  -x, --extensions        use all syntax extensions\n\
  --filter-html           filter out raw HTML (except styles)\n\
  --filter-styles         filter out HTML styles\n\
  -c, --compatibility     markdown compatibility mode\n\
  -b, --batch             process multiple files automatically\n\
  -e, --extract           extract and display specified metadata\n\
\n\
Syntax extensions\n\
  --smart --nosmart       toggle smart typography extension\n\
  --notes --nonotes       toggle notes extension\n\
  --process-html          process MultiMarkdown inside of raw HTML\n\
  --nolabels              do not generate id attributes for headers\n\
\n\
Converts text in specified files (or stdin) from markdown to FORMAT.\n\
Available FORMATs:  html, latex, memoir, beamer, odf, opml\n");
}

If you can point me to the docs you are looking at, I can try to see how that might work.

This is actually the functionality I was after - just found it after more research:

Ah I see. Yeah, this is still using peg-multimarkdown so it doesn't have those extra flags. You'd have to upgrade the MMD library to https://github.com/fletcher/MultiMarkdown-4
