I want to modify and view github wikis with local editor like Emacs, and Google Code wikis can be checked out just like code. Is there any way to checkout github wikis? Or i
You can't check out the wiki but you can set up a website that you can checkout and edit that gets regenerated on a push.
They call it GitHub Pages. Admittedly, not the same as a wiki though.
You can now!
git clone https://github.com/user/project.wiki.git
or if you use ssh
git clone git@github.com:username/project.wiki.git
