単にテンプレート的にhtmlを吐き出す
単純に関数に代入してhtmlを作ってみたがお世辞にも簡潔には書けなかった。。

htmlを吐き出してみる。

上のextensionは簡便のため。
レイアウト
使用するスタイルシートwebroot/css/cake.hello.cssを用意する。
body { background: #eee; color: #999; margin: 10px 8px } #header { font-size: 18pt; font-weight: bold; margin: 10px; } #content { background: #fff; color: #999; padding: 10px 25px 30px 25px; font-size: 14pt; } #footer { text-align: right; font-size: 12pt; margin: 10pt; } h1 { color: #aaa; font-size: 24pt; margin: 20pt 0pt 50pt 0pt; }
cssを利用するレイアウトsrc/Template/Layout/hello.ctpファイルを用意する。
<!DOCTYPE html> <html> <head> <?= $this->Html->charset() ?> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title> <?= $this->fetch('title') ?> </title> <?= $this->Html->meta('icon') ?> <?= $this->Html->css('cake.hello.css') ?> <?= $this->fetch('meta') ?> <?= $this->fetch('css') ?> <?= $this->fetch('script') ?> </head> fetchでコントローラの変数を取ってきている。 <body> <div id="container"> <div id="header">header</div> <div id="content"> <?=$this->fetch('content') ?> </div> <div id="footer">footer</div> </body> </html>
ここではcake.hello.cssを読み込んでいるが、javascriptも読み込みたい場合、
webroot/js/cake.hello/jsなどというファイルをつくり
<?= $this->Html->script('cake.hello.js') ?>
を追加してやれば良い。
コントローラでレイアウトを指定する。
<?php namespace App\Controller; class HelloController extends AppController { public $name = "Hello"; public $autoRender = true; public function index() { $this->ViewBuilder()->layout('Hello'); } } ?>
テンプレート
src/Template/Hello/index.ctpを作ってテンプレートを以下のように用意
<!DOCTYPE html> <html lang="ja"> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <title>Hello Page</title> </head> <body> <h1>midashi</h1> <p> hello hello </p> </body> </html>
コントローラ側でautoRenderをtrueにしてテンプレートを読み込む。
<?php namespace App\Controller; class HelloController extends AppController { public $name = "Hello"; public $autoRender = true; public function index() { $this->viewBuilder()->autoLayout(false); } } ?>
自動レイアウト(autoLayout)はなしにした。
テンプレート名を変えればその名前のアクションに適用される。
自動レイアウトを使用する場合はテンプレートは
<h1>midashi</h1> <p> hello hello </p>
のみで良く。コントローラの方は $this->viewBuilder()->autoLayout(false);の行を削る。
これでデフォルトのレイアウト(src/Template/Layout/default.ctp)が適応される。
フォワードとリダイレクト
<?php namespace App\Controller; class HelloController extends AppController { public $name = "Hello"; public $autoRender = false; public function index() { echo "hello, world!!"; } public function other() { echo "hello, other world!!"; } public function forw() { $this->setAction(other); } public function red() { $this->redirect("/hello/other"); } } ?>
フォワードはアクションを指定。サーバ内で閉じる。
リダイレクトはアドレスを指定、ブラウザにページ移動を依頼する。
Hello World
/helloにアクセス
<?php namespace App\Controller; class HelloController extends AppController { public $name = "Hello"; public $autoRender = false; public function index() { echo "hello world!!"; } } ?>
/hello/otherにアクセス
<?php namespace App\Controller; class HelloController extends AppController { public $name = "Hello"; public $autoRender = false; public function index() { echo "hello, world!!"; } public function other() { echo "hello, other world!!"; } } ?>
otherはotherアクションと呼ばれる。
プロトコルMisc
CustomStringConvertible description オブジェクトの文字表示 print
CustomDebugStringConvertible debugDescription オブジェクトの文字表示 debugPrint
LosslessStringConvertible 文字列からそのままオブジェクト構築できる
TextOutputStream write(_ string: String)
TextOutputStreamable writeの拡張 write
Hashable ハッシュ。ハッシュが違えば違う。ハッシュが同じでもおなじとは限らない。
Comparable 比較
Equatable 同じ
BitwiseOperations ビット計算できる
AnyObject 任意のオブジェクト
Error エラー
OptionSet ビットでつかっている。SetAlgebra, RawRepresentable。使うと便利かも？
AnyHashable構造体
任意のHashableなものなら受け入れる引数等を作りたいときにつかう。いわゆるtype-erased。
標準入力から一行受け取る。trueはその一行は標準入力から切り出すかを示す。
public func readLine(strippingNewline: Bool = default) -> String?
コマンドライン
public enum CommandLine { public static var argc: Int32 { get } // argvの値 public static var unsafeArgv: UnsafeMutablePointer<UnsafeMutablePointer<Int8>?> { get } // swift用に変換される？のか？ public static var arguments: [String] }
Unmanaged構造体
自分でメモリ管理するもの
強参照のチェック
isKnownUniquelyReferenced
一個だけから強参照されているかを見る。weakに複数参照されていてもOK。
