Use commonmark to generate html from a list of markdown files

md2html.js

#!/usr/bin/env node
var fs = require('fs');

var convert = function(markdown) {
	var reader = new cm.Parser();
	var writer = new cm.HtmlRenderer();
	var parsed = reader.parse(markdown);
	var result = writer.render(parsed);
	return result;
};

var read = function(filename) {
	var markdown = fs.readFileSync(filename,'utf8');
	return convert(markdown);
};

var write = function(filename,html) {
	fs.writeFileSync(filename,html,'utf8');
};

var list = function(path) {
	path = path + '/';
	var files = fs.readdirSync(path);
	var remrk = /\.md$/i;
	return files
		.filter((f)=>remrk.test(f))
		.map((f)=>[path+f,path+'html/'+f.replace(remrk,'.html')]);
};

list(process.cwd()).forEach((f)=>write(f[1],read(f[0])));
