基于 TOGoS/PHPGitIgnore 用于解析和应用 .gitignore 类规则的实现

1、现阶段存在一个文件夹，其中包含一个类似于 .gitignore 的配置文件：.themeignore，其内容如下

node_modules/*
npm-debug.log
yarn-error.log
*.bak
*.swp
*.map
*.LICENSE.txt
.DS_Store
css/*
fixtures/*
images/*
js/*
mix/*
modules/*/images/*
modules/*/js/*
.browserslistrc
.env
.env.*
.themeignore
babel.config.json
jsconfig.json
package.json
postcss.config.js
README.md
tailwind.config.js
webpack.mix.js

2、需要基于此文件配置将一些文件忽略掉，仅纳入需要的文件。比如说：过滤掉 node_modules/* 。如图1

3、基于 Composer 安装 togos/gitignore

PS E:\wwwroot\object> composer require togos/gitignore
Info from https://repo.packagist.org: #StandWithUkraine
Using version ^1.1 for togos/gitignore
./composer.json has been updated
Running composer update togos/gitignore
Loading composer repositories with package information
Updating dependencies
Lock file operations: 2 installs, 0 updates, 0 removals
  - Locking demo/facebook-conversions-api (2.2.0)
  - Locking togos/gitignore (1.1.1)
Writing lock file

4、最终参考 /vendor/togos/gitignore/src/test/php/TOGoS/GitIgnore/FileFinderTest.php 实现如下

use TOGoS_GitIgnore_FileFinder;
use TOGoS_GitIgnore_Ruleset;

	protected $results;
	public function addResult($f, $result) {
		$this->results[$f] = $result;
	}

	/* 测试忽略文件 */
	$rules1Content = file_get_contents('E:/wwwroot/object/resources/views/theme/.themeignore');
	$finder = new TOGoS_GitIgnore_FileFinder(array(
		'ruleset' => TOGoS_GitIgnore_Ruleset::loadFromString($rules1Content),
		'invertRulesetResult' => false,
		'defaultResult' => false,
		'includeDirectories' => false,
		'callback' => array($this,'addResult')
	));

	$this->results = array();
	$finder->findFiles('E:/wwwroot/object/resources/views/theme');
	var_dump($this->results);

	exit;

5、打印 $this->results，结果如下，符合预期。文件路径所对应的值为 true，则表示此路径对应的文件为忽略。如图2

图2

array(685) {
  [".browserslistrc"]=>
  bool(true)
  [".env"]=>
  bool(true)
  [".env.development"]=>
  bool(true)
  // ...
  ["tailwind.config.js"]=>
  bool(true)
  ["theme.json"]=>
  bool(false)
  ["webpack.mix.js"]=>
  bool(true)
}

6、可以基于老的目录再生成一个新的干净的目录，只需要遍历目录时，基于 $this->results 判断即可。
