在我最近的项目中,处理控制台命令,我需要根据 linux 标准约定执行/运行 json 中提到的各种操作
what:mv(Move),type:file,dir
what:mkdir(Make Directory)
what:touch(Make File)
what:cp(Copy), type:file,dir
what:echo (Write into File), type:override,append
what:sed (Find and Replace in file)
并且 param 模式与 linux 约定几乎完全相同。
当前设置(Mkdir,触摸)
Json 模式(数组)
"actions" => [
[
'what' => "mkdir",
'param' => [
'name' => "cache",
'in' => "bootstrap",
],
],
[
'what' => "touch",
'param' => [
'name' => ".gitignore",
'in' => "bootstrap/cache",
],
]
],
它遍历所有动作并解析每个what
类型(mkdir,touch)的动作类,例如MkdirOperation
分别用于mkdir和调用句柄函数。
<?php
use Symfony\Component\Filesystem\Filesystem;
use Symfony\Component\Filesystem\Exception\IOExceptionInterface;
class MkdirOperation extends Operation
{
const ATTR_IN = "in";
const ATTR_NAME = "name";
public function handle()
{
$path = $this->_path();
$this->oIO->comment($path);
if ($this->oFileSystem->isAbsolutePath($path)) {
try {
$this->oFileSystem->mkdir($path);
} catch (IOExceptionInterface $e) {
echo "An error occurred while creating your directory at "
.$e->getPath();
}
$this->oIO->info("Directory created at:".$path);
}
}
private function _path()
{
return $this->oConfig->getBaseDir()
.$this->aParam[self::ATTR_IN].DIRECTORY_SEPARATOR
.$this->aParam[self::ATTR_NAME]
.DIRECTORY_SEPARATOR;
}
}
要求:
//somefile.php
$path = "/var/www/ins/"
//someotherfile.php
return [
'files' = [
'Path\\To\\NameSpace',
'Path\\To\\NameSpace'
]
];
所以,基本上我想根据特定规则更新/覆盖我提到的变量/数组,为此,我尝试在 json 模式中准备规则:
"actions": [
{
"what": "sed",
"in": "path/to/somefile.php",
"find": {
"type": "variable",
"value": "path"
},
"replace": {
"type": "variable",
"value": "__DIR__.'/../vendor/compiled.php';"
}
},{
"what": "put",
"value": "Path\\To\\NameSpace",
"in": "path/to/someotherfile.php",
"find": {
"type": "array",
"at": "files"
}
}
]
我正在使用的组件
- symfony/控制台
- symfony/finder
- Symfony/文件系统
寻找:
- 建议以这种方式组织规则集模式,以迭代更新/覆盖变量或从数组中推/拉元素的所有操作并执行操作。
- 更新特定变量值的机制,以及使用 php 从数组/子数组中推/拉元素的机制。
如果我身边仍有不清楚的地方,请告诉我。提前致谢。
