"without a file extension" -> also works for .coffee .json .md

Thanks for this plugin!

My suggestion is to change the wording in the readme, since it works for all of these text file extensions that don't work with QuickLook out of the box.

The plugin indeed is awesome. I had this also working with .sh files on Mavericks. After the 'upgrade' to Yosemite QuickLook no long works with .sh files (at least on my system). Anybody else having this issue? Is there a workaround?

I assumed that qlstephen was taking care of this for me, but upon inspection, I have qlcolorcode installed, and that's taking care of the source-code quicklook for me. Have a peek at it, maybe it'll fit your needs.

Also, if you need a (customizable) Markdown previewer, have a look at qlmarkdown. I believe you can tweak the CSS to fit your liking, though I haven't played with that yet.

I'd love to see a workaround or option to specify some files for qlstephen to ignore, or perhaps (as in your case) some filetypes for it to handle.

TL;DR: qlstephen is not greedy about matching file types so any QL plugin that specifies a specific file type will be chosen over qlstephen.

qlstephen uses the public.data UTI which is described by Apple as the "Base physical type for byte streams (flat files, pasteboard data, and so on)". Because of this anything that is more specific will be chosen over it. This allows qlstephen to play nice with other QL plugins.
