2. Hello World

インストールが完了したので、実際に簡単なページを作ってみます。
以下の順番で作業を行います。

バンドルの作成
ルートの作成
コントローラの作成
テンプレートの作成

1) バンドルの作成

blogチュートリアル(3) バンドルの作成 | Symfony2 Blog チュートリアル

まずは、バンドルを作成します。
バンドルっていうのはある機能の塊をしめし、プロジェクトの小っちゃい版みたいな感じです。
何かを作るときは必ずバンドル内に作成することになります。

まず、以下のコマンドを実行します。

$ php app/console generate:bundle --namespace=Acme/HelloBundle --format=yml

1	$ php app/console generate:bundle --namespace=Acme/HelloBundle --format=yml

すると、会話形式で入力を求められるので適当に入力していきます。

$ php app/console generate:bundle --namespace=Acme/HelloBundle --format=yml


  Welcome to the Symfony2 bundle generator


Your application code must be written in bundles. This command helps
you generate them easily.

Each bundle is hosted under a namespace (like Acme/Bundle/BlogBundle).
The namespace should begin with a "vendor" name like your company name, your
project name, or your client name, followed by one or more optional category
sub-namespaces, and it should end with the bundle name itself
(which must have Bundle as a suffix).

See http://symfony.com/doc/current/cookbook/bundles/best_practices.html#index-1 for more
details on bundle naming conventions.

Use / instead of \ for the namespace delimiter to avoid any problem.

Bundle namespace [Acme/HelloBundle]: 

In your code, a bundle is often referenced by its name. It can be the
concatenation of all namespace parts but it's really up to you to come
up with a unique name (a good practice is to start with the vendor name).
Based on the namespace, we suggest AcmeHelloBundle.

Bundle name [AcmeHelloBundle]: 

The bundle can be generated anywhere. The suggested default directory uses
the standard conventions.

Target directory [/home/hogehoge/public_html/symfony2/src]:

Determine the format to use for the generated configuration.

Configuration format (yml, xml, php, or annotation) [yml]:

To help you getting started faster, the command can generate some
code snippets for you.

Do you want to generate the whole directory structure [no]? yes


  Summary before generation


You are going to generate a "Acme\HelloBundle\AcmeHelloBundle" bundle
in "/home/hogehoge/public_html/symfony2/src/" using the "yml" format.

Do you confirm generation [yes]? 


  Bundle generation


Generating the bundle code: OK
Checking that the bundle is autoloaded: OK
Confirm automatic update of your Kernel [yes]? 
Enabling the bundle inside the Kernel: OK
Confirm automatic update of the Routing [yes]? 
Importing the bundle routing resource: OK


  You can now start using the generated code!

$ php app/console generate:bundle --namespace=Acme/HelloBundle --format=yml

これでバンドルの作成は完了です！

$ php app/console generate:bundle --namespace=/ --format=

1	$ php app/console generate:bundle --namespace=/ --format=

作成するために実行した、symfony2コマンドの書式は上のような形式になります。
