Creating a clean gh-pages branch

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" &gt; index.html

太一のコードの読み方メモ

Retaining line numbers with the Rails asset pipeline

By default the Rails 3 asset pipeline uses the Uglifier gem to optimize and minify your Javascript. One of its many optimisations is to remove all whitespace, turning your Javascript into one very long line of code.

Whist removing all the newlines helps to reduce the file size, it has the disadvantage of making your Javascript harder to debug. If you've tried to track down Javascript errors in minified Javascript files you'll know the lack of whitespace does make life harder.

Luckily there is a simple solution: to configure Uglifier to add newlines back into the code after it performs its optimisations. And if you're serving your files correctly gzip'd, the newlines add only a small increase to the final file size.

You can configure Uglifier to add the newlines by setting the following in your Rails 3 config/production.rb file:

	{
	val script = "hello.d"
	seq(
	TaskKey[Unit]("dmd") <<= (compile in Compile).map{ _ =>
	val ret = ("dmd -run " + script) !;
	if(ret != 0)sys.error("compile fail")
	}
	,
	watchSources += file(script)
	)

	load 'rake/helper.rb'

	desc "Set up the VM"
	task :up do
	vm = VM.new
	vm.cli('up')
	end

	desc "Shutdown the VM"
	task :graceful_down do

	def index(id:String) = Action {
	getFirstData(id)
	}
	private def getFirstData(id:String) = {
	Cache.get(id) match {
	case Some(id2) => getSecondData(id2)
	case None => NotFound
	}
	}
	private def getSecondData(id2:String) = {

	Compile as follows:
	scalac Common_1.scala Macros_2.scala
	scalac Common_1.scala Test_3.scala -cp <path to the result of the previous compilation>

	Tested in 2.10.0-M3, will most likely not compile by the time 2.10.0 final is released, because we're actively rehashing the API.
	However the principles will remain the same in the final release, so the concept itself is okay.
	upd. Code updated for 2.10.0-M7.
	upd. Code updated for 2.10.0-RC1.
