convert gemtext to html

gmiToHtml.js

// file = { "filePath": "gemtextFileContent" }
// callback = function called once done
function generateHTML(files, callback) {
	console.log("\x1b[90m->\x1b[0m generating html site...");

	});

	function checkProgress(i) {

	}
}

oh yeah there are no multi-line block quotes lol i'll have to add those later
