Here other techniques such as compiling an abstract syntax tree and resolving variables in closures are discussed. 在这里,对其它技术(如:编译一个抽象语法树(AST)和解析闭包中的变量)也进行了讨论。
This time, you will fetch all of the import statements in the abstract syntax tree. 这一次,您可以读取抽象语法树(AST)中的所有导入声明了。
You define a language by defining the structure of its abstract syntax tree, its abstract grammar. 定义语言就是定义它的抽象句法树,它的抽象文法。
An abstract syntax tree is an expression represented as a collection of objects. 抽象语法树(AST)是一个表示为对象集合的表达式。
This pattern is often reapplied several times through a rule as you dig down through an abstract syntax tree. 在您沿着抽象语法树(AST)深入时,该模式通常会通过一条规则重复应用几次。
