针对常用文本处理工具、方法中无法有效地对上下文无关语法描述的源代码进行结构查询、匹配这一问题,提出基于TXL语言语法编程功能的解决方法。 TXL是一种语言转换和快速原型构建系统,其核心是TXL编程语言。利用其强大的语法编程功能,可以轻松实现对任意可以用上下文无关语法描述的语言进行解析变换,实现特定结构的匹配、检索与转换功能。介绍TXL语言基本概念及使用方法,结合日常工作经验介绍其在文本处理、编程语言处理与转换等方面的应用。实践证明,TXL编程能有效解决传统文本处理工具在词法标记、语法解析及代码转换上的实现代价,实现高效率的源码文本处理功能。

This paper proposed a source code processing method using TXL’s grammar programming ability, efficiently overcoming text processing domain of context-free languages which traditional processing tools can’t deal with. TXL is a programming language transformation and rapid prototyping system, and its core is the TXL programming language. Armed with strong grammar programming ability, it”s easy to parse any languages that can be described in context-free grammar and do pattern matching, retrieval and transforming functionalities. This paper introduced the basic concepts and elementary usage of this language, provided some applicable examples drawn from real programming experiences and practices. As improved, TXL can reduce the overall cost of tokenization, parsing and transformation introduced by tranditional tools and implements high efficient source code processing.
