github gist snippet management

I found a way to post gists to Github in the terminal with a ruby gem, however, I would actually like a way to retrieve those gists, aka, use them as snippets, as well. I'm quite sure it's possible, but I'm not very familiar with the Gist api, and I'm also a bit of a latecomer to the Linux systems.

I'm using Linux Mint 17.1 with Cinnamon, though I do have a live CD for the KDE variation of Linux Mint that I've been testing out. I would prefer an answer that includes both a gui based and cli based solution, as I'm trying to learn to better use CLI.

I know there are gist options for specific editors, but I'd prefer something that doesn't require a specific program to work.

PS. I apparently posted this question to the wrong place originally, they told me to post it here instead.
