您要查找的是不是：
- The framework has a number of predefined semantic action functors. 库框架包含了一系列预定义的语义动作仿函数。
- When successful, the parser calls a client-supplied semantic action. 成功匹配时，将执行客户程序提供的语义动作。
- Backtracking and semantic actions do not mix well. 回溯和语义动作混用不是太好。
- In LR parsing, before a symbol is recognized, it is difficult to invoke the semantic action associated with the symbol. LR剖析中，在识别一个符号之前，执行该符号相关的语意动作是极困难的。
- Before a symbol is recognized in LR parsing, it is difficult to invoke the semantic action associated with the symbol. LR剖析中，在识别一个符号之前，执行该符号相关的语意动作是极困难的。
- The most obvious way of course is through semantic actions. 当然，最明显的方法是通过语义动作来修改。
- Finally, the semantic action extracts structural information depending on the data passed by the parser and the hierarchical context of the parser it is attached to. 最后，语义动作从分析器中获得结构化的信息，这些信息依赖于分析器传剃的数据和分析器所处的语境层次。
- The function and functor signature of a semantic action varies depending on the parser where it is attached to. The following table lists the parsers that accept unique signatures. 语义动作的函数和仿函数的签名的变化取决于它被挂接到哪个分析器上。下面的表格列举了接受一元函数签名的分析器。
- Key Words: parser generators, LR(k) grammars, semantic actions, parse tree, free positions. 关键词 ：剖析器产生器、LR(k)文法、语意动作、剖析树、自由位置。
- Breaking the operands into separate lines puts the semantic actions neatly to the right. 将操作数分开到不同的行，将相应的语义动作放在右边。
- Semantic actions may be attached to any expression at any level within the parser hierarchy. 语义动作可以挂接到分析器内任意层次的任意表达式上。
- The first approach is to delay all semantic actions until the whole parse tree is constructed. 第一种做法是延迟所有语意动作，直到建立完整的剖析树。
- There are a few fundamental concepts that need to be understood well: 1) The Parser , 2) Match , 3) The Scanner , and 4) Semantic Actions . 有少数的基本概念是必须了解清楚的，他们是：1）分析器2）匹配3）扫描器4）语义动作。
- Actually, the problem is that both semantic actions of the int and real branch will be triggered because both branches will be tried. 实际上，问题是整数和实数分支的语义动作都被触发了，因为两个分支均被尝试。
- Semantic actions in look-aheads, look-behinds and independent sub-expressions execute eagerly instead of causing a crash. 在顺序环视、逆序环视中语义动作以及独立子表达式的执行不再导致崩溃。
- Closure variables can be accessed from within semantic actions just like you would struct members: by qualifying the member name with its owner rule, subrule or grammar. 闭包变量可以在语义动作中访问，就用你组织成员变量的方式：指定它所属的规则、子规则或语法以及闭包变量的名字。
- Typically, we store temporary variables, generated by our semantic actions, in our closure variables, as a means to pass information up and down the recursive descent. 典型地，我们在闭包里储存由我们的语义动作产生的临时变量，以之作为在递归下降中向上或向下传递信息的方法。
- He is a very good footballer; you ought to see him in action. 他是一位出色的足球运动员，你应该看他踢球。
- The article is a savage attack on her past action. 那篇文章对她过去的行为进行了恶毒的攻击。
