This is a very interesting cli, its so simple. I stumbled accross the gi command awhile back and was like pfft, I dont want to install something for that. Didn't even realize that you don't install it, its just http. Their install instructions lead you to putting a curl funtion in your bashrc.
function gi() { curl -sLw \"\\\n\" https://www.toptal.com/developers/gitignore/api/\$@ ;}
This now has me wondering "What else can build like this?"
