gyokuro: A Ceylon web framework

A new web framework, along the lines of Spark is available on Herd.  Here's a quick sample along with some ceylon.html.

	import com.github.bjansen.gyokuro { ... }
	import ceylon.net.http.server { ... }
	import ceylon.html { ... }
	import ceylon.collection { ... }
	import ceylon.math.float { ... }
	class Book(author, title) {
	shared variable String author;
	shared variable String title;
	string => "Title: ``title`` \nAuthor: ``author``";
	}
	String bookid() => (random() * 100).integer.string;
	MutableMap<String, Book> books = HashMap
	{
	bookid() -> Book("George Eliot", "Middlemarch"),
	bookid() -> Book("Eudora Welty", "A Curtain of Green: And Other Stories"),
	bookid() -> Book("Evelyn Waugh", "The Loved One"),
	bookid() -> Book("John Dos Passos", "U.S.A.: The 42nd Parallel / 1919 / The Big Money")
	};
	String book_handler(Request req) {
	if(is String[2] params = [req.parameter("author"), req.parameter("title")]) {
	books.put(bookid(), Book(*params));
	}
	return index.string;
	}
	void delete_book(Request req) {
	if (exists id = req.parameter("id"),
	exists book = books.remove(id)) {
	}
	redirect("/books");
	}
	shared void run() {
	get("/books", `book_handler`);
	post("/books", `book_handler`);
	post("/books/delete/:id", `delete_book`);
	Application {}.run();
	}
	Html index = Html {
	doctype = html5;
	Head {
	title = "Book Collection";
	CssLink("https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css")
	};
	Body {
	Div {
	classNames = "container";
	Div {
	classNames = "row";
	Div {
	classNames = "col-md-4";
	H4("We have ``books.size`` books"),
	Div {
	classNames = "list-group";
	for (i->book in books.indexed) {
	Form {
	action = "/books/delete/";
	method = "post";
	Input {
	classNames = "form-control";
	name = "id";
	valueOf = book.key;
	type = hidden;
	},
	Div {
	classNames = "list-group-item";
	H4 {
	classNames = "list-group-item-heading";
	"``i + 1 ``. ``book.item.title``"
	},
	P {
	classNames = "list-group-text";
	"``book.item.author``";
	Button {
	classNames = "btn btn-danger btn-xs pull-right";
	"delete";
	type = submit;
	}
	}
	}
	}
	}
	}
	},
	Div {
	classNames = "col-md-4";
	Form {
	action = "/books";
	method = "post";
	Div {
	classNames = "form-group";
	Label("Author"),
	Input {
	classNames = "form-control";
	name = "author";
	required = true;
	placeholder = "Enter an author's name";
	}
	},
	Div {
	classNames = "form-group";
	Label("Title"),
	Input {
	classNames = "form-control";
	name = "title";
	required = true;
	placeholder = "Enter a book's title";
	}
	},
	Button {
	text = "add this book";
	type = submit;
	classNames = "btn btn-primary";
	}
	}

	}
	}
	};
	};

Ceylon 1.0.0 example

I'm a big fan of the Ceylon Programming Language, simply because I find the code easy to read. But I don't see enough Ceylon code samples out on the net, so here is an example based on some lambda experiments with a few other JVM languages. Sadly, Ceylon was not among them and so I'm adding it to the chorus:

I send my thanks to the author of the original examples.
