I'll note before we go any further that the terms parse tree and abstract syntax tree (or AST) describe very similar grammatical structures.
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。
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.
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。
Traverses the abstract syntax tree (AST) one or more times, collecting information and checking that the input program makes sense.
遍历抽象语法树(abstract syntax tree,AST)一次或多次，收集信息并检查输入程序makessense。
For that, you would turn to something quite familiar to compiler aficionados: the JDT's Abstract Syntax Tree (AST) framework.
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(Abstract Syntax Tree,AST)框架。
In IDEA and Eclipse, your code looks like a text view, but the development environment is actually editing the Abstract Syntax Tree (AST).
在idea和eclipse中，您的代码看上去像一个文本视图，但是开发环境实际上正在编辑Abstract Syntax Tree (ast)。
MPS maintains the code in an Abstract Syntax Tree ( AST), which consists of nodes with properties, children and references, and fully describes the program code.
MPS用一棵抽象句法树（AST）来维护代码。
A lack of a pure Ruby parser has been negligible for some time in Ruby's history, since getting the Abstract Syntax Tree (AST) of some Ruby code was possible with utilities such as ParseTree.
因为可以使用类似语法分析树(ParseTree)的通用方法来对Ruby代码进行分析并获得抽象语法树(Abstract Syntax Tree)，所以在Ruby历史上的一定时期内，纯ruby语法分析器的缺失被忽视了。
Because you have defined this extension to be invoked when the transformation is processing a UML class, you can safely type the target object to an Abstract Syntax Tree (AST) TypeDeclaration object.
因为当转换处理UM l类时，您已经定义调用该扩展，所以您可以安全地向Abstract Syntax Tree (ast)TypeDeclaration对象输入目标对象。
With the emphasis on the abstraCt syntax tree (AST), the paper also discusses the structure of a disk file as well as the functions designed for saving and recovering the AST.
主要分析了抽象语法树(ast)，讨论了磁盘文件的结构及ast的写入和复原技术。
