I’ve recently (and finally) started using Markdown and MultiMarkdown, two excellent tools for writers. Markdown was created by John Gruber, in 2004. What it does is simple and brilliant: Markdown allows you to write using plain text, without a lot of markup or effort, and then export your writing as HTML. So instead of creating H tags, you can do just this:
# This is a Header 1
## This is a Header 2
To create emphasis, text is wrapped with one or two asterisks or underlines: Here is some *emphasis*. Here is more **emphasis**. You want to create a new paragraph? Just add a blank line. Simple! There are also ways to create lists, links, add images, and so forth.
You can learn the basics and the syntax at Gruber’s site, which also has an online tool, named Dingus, for converting Markdown text to HTML. What’s great about Markdown is there aren’t many rules to learn and you can write using it so easily. If you do a lot of writing that gets published online, like a blog, Markdown really lets you focus on the writing without spending too much time creating and balancing tags. Secondarily, text written using Markdown is easy to read, which means it’s also easier for the original writer to edit. If you work with a team of people on documents, there’s a lot to be said for Markdown as a format to use.
MultiMarkdown, which I haven’t used as much yet, is an extension of Markdown, adding features that Fletcher Penney, its creator, thought necessary. For starters, Multimarkdown lets you quickly create tables, footnotes and citations, metadata, definition lists, and more. More importantly (to me) MultiMarkdown can also be exported to more formats beyond HTML, because MultiMarkdown includes a tool that supports LaTeX. Through it, you can create PDFs, RTF documents, Word documents, and more. This means you can create entire books, PDF articles, and presentations using MultiMarkdown (along with HTML documents, of course).
Neither Markdown nor MultiMarkdown is something everyone needs, but if you do writing that needs to be published in HTML format, or in multiple formats, both are worth checking out.
