抽象语法树（AbstractSyntaxTree，AST）作为程序的一种中间表示形式，在程序分析等诸多领域有广泛的应用。

为了避免这种缺陷，您可以使用Java的抽象语法树（AST）来识别这种问题，从而重新构筑规则。

To avoid this flaw , you will reconstruct the rule by using Java 's abstract syntax tree ( AST ) to identify the problems .

Rubyparser还能提供抽象语法树节点的源码位置，这是Ruby代码分析或者代码转换工具的必需信息。

Ruby_parser also provides source locations of AST nodes , which is obviously necessary for code analysis or code transformation tools in Ruby .

因为您会转而使用一些对编译器迷而言十分熟悉的工具：JDT的抽象语法树（AbstractSyntaxTree，AST）框架。

For that , you would turn to something quite familiar to compiler aficionados : the JDT 's Abstract Syntax Tree ( AST ) framework .

是一条命令接着一条命令地转还是先构建出完整的抽象语法树并对其优化呢，就像GWT将Java转换为JavaScript那样？

Do you translate command-by-command or do you build the full Abstract Syntax Tree and optimize on that as GWT does for translating Java to JavaScript ?

元模型使用MOF正式的定义一系列建模构想的抽象语法。

A metamodel uses MOF to formally define the abstract syntax of a set of modeling constructs .

对于Groovy代码的抽象语法树的分析，可以让我们搜集到我们需要的所有相关信息。

The analysis of the abstract syntax tree of the Groovy code , allows us to collect all relevant information we need .

1抽象语法表示、BER编码规则及其XML改进、数据库设计等，并给出了具体的解决方法和实现程序。

Syntax , the BER coding rules and the design for supporting database etc. The exact method and program for implementation of document delivery are also presented in the paper .

通过BNF描述了DFL程序设计语言的抽象语法；

The abstract syntax of DFL programming language was described through BNF notation ;

给出解析抽象语法树所使用的词法规则和语法规则，提出了解析GCC抽象语法树的方法。

Lexical rules and syntax rules used for parsing syntax trees are given , and a method for parsing GCC is proposed .

纯Ruby语法分析器提供了改变这种情况的机会&RubyIDE（或者其他工具）可以获得Ruby的抽象语法树，同时避免被绑定到特定的语法分析器实现上。

The pure Ruby parser now offers a chance to change that-a Ruby IDE or other tool , can now get at a Ruby AST without getting locked in .

在我们继续之前，我要特别提一下，术语解析树和抽象语法树（或AST）描述了非常相似的语法结构。

I 'll note before we go any further that the terms parse tree and abstract syntax tree ( or AST ) describe very similar grammatical structures .

因此在论文研究工作中，作者主要研究了C语言静态分析器的实现原理，并且介绍了C静态分析框架前端部分所涉及的预处理过程、抽象语法树等部分的内容。

This paper is mainly about the implementation principles of the static analyzer of C language and the process of C program language pretreatment and the abstract syntax tree , which are involved in the front-end part of the C language static analysis framework .

其次，对GCC抽象语法树文本进行了标准化及消除文本中与控制流分析和数据流分析无关的冗余信息。

Secondly , the abstract syntax tree text is standardized and the redundant information unrelated to the control flow analysis and data flow analysis is eliminated .

您可以添加新规则：可以通过编写Java代码并重新编译PDM，或者更简单些，编写XPath表达式，它会针对每个Java类的抽象语法树进行处理。

You can add new rules , either by writing Java code and recompiling PMD or , a little more simply , by writing XPath expressions that are resolved against each Java class 's abstract syntax tree .

Erlang语言（由Ericsson开发）使用一个VM来执行Erlangbytecodes，且通过源的抽象语法树解译Erlang。

The Erlang language ( developed by Ericsson ) uses a VM to execute Erlang bytecodes and also to interpret Erlang from the source 's abstract syntax tree .

这种面向对象的语义模型建模每个语言构件的抽象语法、静态和动态语义为单个Object-Z类构件，具有简洁性、可组合性和可重用性，适应了XML家族语言不断变化发展的特点。

This Object-Oriented semantic model describes abstract syntax , static and dynamic semantics of each language construct as single Object-Z class . This highly structured semantic model is concise , composable and reusable .

严格说来，AST（抽象语法树）也是一种IR&因为它既不是源代码，也不是目标语言。

Strictly speaking , the AST ( abstract syntax tree ) is also an IR ( intermediate representation )– since it is not quite the source , and not quite the target language .

有些工作，像RyanDavis的分析树，用的是Ruby解释器的分析器（通过一个本地扩展）来获得Ruby源码的抽象语法树（AST）。

There are workarounds , like Ryan Davis'ParseTree which uses the parser of Ruby 's interpreter ( via a native extension ) to get at the Abstract Syntax Tree ( AST ) for Ruby source .
