##注意

想要自定义参数 比如短参数必须使用两个方法 getArguments() 和 getOptions()

###补充

又看了遍源码 找到更方便的方法 这个文档里没有写 所以下面两种方法都可以

1
2
3
4
//直接设置属性就可以了 切记短参数放在前面用 | 分割
protected $signature = 'make:view {name : like content or article/content} {--l | layout : create new layout}';

//这里还要注意一点是 在Parser.php 里的 $matches = preg_split('/\s*\|\s*/', $token, 2); 中间的 \| 是转义成了 | 字符 不要在忽略 认为是或了 给自己提个醒
