nl_tokens: 从源文件派生出来的子文件，典型比如 Component 文件可以派生出脚本、模板、样式等子文件
pl_tokens: function addSubFile ( file ) { if ( ! file ) { return ; } this . subFiles || ( this . subFiles = [ ] ) ; if ( ! this . subFiles . includes ( file ) ) { file . isSubFile = true ; file . <mask> = this ; this . subFiles . push ( file ) ; } }
