composer 自定安装包路径

1、Github新建一个项目
代码结构如下

composer.json配置如下

 {
    "name": "fationyyk/self-test-package",
    "type" : "composer-plugin",  // 必须指定类型为 composer-plugin
    "description": "testcomposer",
    "authors": [
        {
            "name": "fationyyk",
            "email": "[email protected]"
        }
    ],
    "require": {
        "composer-plugin-api": "*"  // 依赖包
    },
    "extra": {
        "class": "fationyyk\\selfpackage\\Plugin"  // 指定加载插件的类
    },
    "autoload": {
        "psr-4": {
            "fationyyk\\selfpackage\\": "src/"
        }
    }
}

src 代码说明

Plugin.php

getInstallationManager()->addInstaller($installer);
    }
}

PluginInstaller.php

getPrettyName() 包的名字
        $prefix = substr($package->getPrettyName(), 0, 23);
        
        if ('fationyyk/push' !== $prefix) {
            throw new \InvalidArgumentException(
                'Unable to install template, phpdocumentor templates '
                .'should always start their package name with '
                .'"phpdocumentor/template-"'
            );
        }
       // 返回指定路径
        return './data/templates/'.substr($package->getPrettyName(), 23);
    }
    /**
     * {@inheritDoc}
     */
    public function supports($packageType)
    {
       
        return 'phpdocumentor-template' === $packageType;
    }
}

2、git上新建另一个项目

composer.json

{
    "name": "fationyyk/push",
    "type":"phpdocumentor-template", // 这里的type必须和PluginInstaller.php里的supports方法支持的类型保持一致
    "description": "Third party message push",
    "authors": [
        {
            "name": "Yanlong Ma"
        }
    ],
    "license": "MIT",
    "require": {
        "php": ">=5.4"
    },
    "autoload": {
        "psr-4": {
            "YanlongMa\\Push\\": "src/"
        }
    }
}

src代码随意

3、发布包，分别发布到https://packagist.org （怎么发包自行百度）

4、使用
新建composer.json文件

{
    "name": "fationyyk/test",
    "type": "fationyyk",
    "description": "test",
    "require": {
        "fationyyk/self-test-package": "dev-master",
        "fationyyk/push": "dev-master"
    }
}

执行composer install
安装后效果如下

fationyyk/push包安装到自定义的data目录下
