This is the sequence of steps to follow to create a root gh-pages
branch. It is based on a question at [SO]
cd /path/to/repo-name
git symbolic-ref HEAD refs/heads/gh-pages
rm .git/index
git clean -fdx
echo "My GitHub Page" > index.html
var parser = document.createElement('a'); | |
parser.href = "http://example.com:3000/pathname/?search=test#hash"; | |
parser.protocol; // => "http:" | |
parser.hostname; // => "example.com" | |
parser.port; // => "3000" | |
parser.pathname; // => "/pathname/" | |
parser.search; // => "?search=test" | |
parser.hash; // => "#hash" | |
parser.host; // => "example.com:3000" |
