创建自己的composer包

创建一个composer/packagist包

 

在github上面创建一个新库，这里取名car, 初始化readme.md, 然后克隆到本地：

git clone https://github.com/maxwelldu/car.git
cd car

 

 

这里的car文件夹就是包的root目录了，只需要记住composer.json在包的哪个目录下面，一般那就是包的root目录了。

现在还没有composer.json文件，可以通过命令： composer init, 中括号里面的为默认值，如果直接回车将使用里面的值

 

➜  car git:(master) composer init


  Welcome to the Composer config generator



This command will guide you through creating your composer.json config.

Package name (/) [maxwelldu/car]:
Description []: composer study
Author [maxwelldu ]:
Minimum Stability []:
Package Type []:
License []:

Define your dependencies.

Would you like to define your dependencies (require) interactively [yes]? no
Would you like to define your dev dependencies (require-dev) interactively [yes]? no
 
  
 
 
  
将composer.json修改成如下：
 
  
 
 
  
{
    "name": "maxwelldu/car",
    "description": "composer study",
    "license": "MIT",
    "authors": [
        {
            "name": "maxwelldu",
            "email": "[email protected]"
        }
    ],
    "minimum-stability": "dev",
    "require": {
        "php": ">=5.3.0"
    },
    "autoload": {
        "psr-4": {
            "Ford\\Escape\\": "src/Ford/Escape",
            "Ford\\Fusion\\": "src/Ford/Fusion",
            "Ford\\Focus\\": "src/Ford/Focus",
            "Ford\\Fiesta\\": "src/Ford/Fiesta"
        }
    }
}
 
  
 
 
  
 
 
  
根据上面的命名空间和目录的映射关系，包的结构现在应该是这样：
 
  
 
 
  
|____.gitignore
 
  
|____composer.json
 
  
|____composer.lock
 
  
|____README.md
 
  
|____src
 
  
| |____Ford
 
  
| | |____Escape
 
  
| | | |____Escape2013.php
 
  
| | |____Fiesta
 
  
| | | |____Fiesta2013.php
 
  
| | |____Focus
 
  
| | | |____Focus2013.php
 
  
| | |____Fusion
 
  
| | | |____Fusion2013.php
 
  
 
 
  
Escape2013.php
 
  
 
 
  
";
    }
}
 
  
 
 
  
Fiesta2013.php
 
  
 
 
  
";
    }
}
 
  
 
 
  
 
 
  
Focus2013.php
 
  
 
 
  
";
    }
}
 
  
 
 
  
Fusion2013.php
 
  
 
 
  
";
    }
}
 
  
 
 
  
以上都梳理完毕后，需要安装composer来测试我们的包是否可以正常工作，安装它很简单在包的root目录下install即可：
 
  
composer install
 
  
 
 
  
安装后会在vendor/composer/autoload_psr4.php中生成命名空间和目录的映射关系，被包在一个数组中：
 
  
 
 
  
 array($baseDir . '/src/Ford/Fusion'),
    'Ford\\Focus\\' => array($baseDir . '/src/Ford/Focus'),
    'Ford\\Fiesta\\' => array($baseDir . '/src/Ford/Fiesta'),
    'Ford\\Escape\\' => array($baseDir . '/src/Ford/Escape'),
);
 
  
 
 
  
然后我们新建一个测试文件show.php,用以下内容填充：
 
  
 
  
 
 
  
然后在当前目录启动一个服务器
 
  
php -S localhost:8080
 
  
 
 
  
 
 
  
打开浏览器输入： http://localhost:8080/show.php
 
  
浏览器上面依次输出了:
 
  
 
 
  
This is Ford Escape2013!
 
  
This is Ford Fiesta2013!
 
  
This is Ford Focus2013!
 
  
This is Ford Fusion2013!
 
  
 
 
  
然后我们将show.php删除，然后将代码推送到github上面
 
  
 
 
  
打开 https://packagist.org/
 
  
用github帐号登录
 
  
 
 
  
然后提交一个包， 将github的地址 [email protected]:maxwelldu/car.git 填上
 
  
然后进行提交即可
