套件介紹

根據套件公開資料產生的選型評估,僅供參考。

一個 Dart 套件,提供 StringScanner 類,透過應用一連串模式來有效解析字串。它在輸入字串中維護一個位置,並支援逐步匹配,非常適合用來建立自訂解析器或處理結構化文字。此掃描器支援前瞻、跳過空白字元及基於模式的提取,讓解析邏輯更加乾淨且易讀。專為編譯器、設定檔讀取器與領域特定語言(DSL)實作而設計,在需要精確控制時,提供了比完整正規表示式引擎更輕量的替代方案。

適用情境

  • 解析設定檔
  • 建構領域特定語言
  • 分詞輸入流
  • 實現自定義語法解析器
  • 處理結構化文本數據

主要特色

  • 增量字串解析
  • 基於模式的匹配
  • 前瞻功能
  • 跳過空白字元
  • 位置追蹤
  • 用於自定義解析器的簡單 API

適合對象

  • 開發人員建構解析器
  • 處理結構化文本格式的人員
  • 需要細粒度文本處理的項目
  • 編譯器或解釋器作者
  • 需要高效標記化的應用程式

使用建議

  • 不適用於複雜的正則表達式模式
  • 需要手動定義模式
  • 最適合順序解析工作流程
  • 有限的內建錯誤處理
  • 效能取決於模式的複雜度
