While I suppose we could turn around and parse these results into expr instances and interpret from there, surely another way must be available.
虽然可以将这些结果解析成expr实例并对其进行解释，但是肯定还有另外一种方法。
MagLev's previous approach to parsing Ruby code was to use an instance of MRI that parses the Ruby code and turns it into a ParseTree s-expr.
之前MagLev解析Ruby代码的手段是使用一个MRI实例，它会解析ruby代码并将其转换为ParseTree s -expr。
Many stylesheet writers use it as a debugging tool, but they find that they also need to use count(expr) when they aren't sure how many nodes expr has.
很多样式表作者使用它作为调试工具，但是又发现如果不清楚expr有多少节点，还是必须使用count(expr)。
To change it to produce instances of our case class AST hierarchy (Expr objects), the return type of the combinators has to be changed to be Parser[Expr].
要将它更改为生成case类AST层次结构的实例（Expr对象），组合子的返回类型必须更改为Parser[Expr]。
The documentation for the expr verb indicates that it can handle many other mathematical functions, such as asin, acos, atan, exponentials, floors, and so on.
根据 expr动词的相关文档的显示，它可以处理许多其他的数学函数，如asin、acos、atan、指数、地板函数等等。
In the original parser, expressions like "5 + 5 + 5" were acceptable owing to the rep combinator in the grammar definition for expressions (expr) and terms (term).
在原来的解析器中，可以接受像“5 + 5 + 5”这样的表达式，因为语法中为表达式(expr)和术语(term)定义了rep组合子。
If you make that change on its own, it will fail to compile; the three combinators know how to take in Strings but not how to produce Expr objects from what's parsed.
如果让它自行更改，编译将会失败；这三个组合子知道如何获取String，但不知道如何根据解析的内容生成Expr对象。
You can use the keyboard to type these in and see expr work; and you should have enough knowledge now to modify the calculator code to add buttons that support these functions.
您可以使用键盘输入这些表达式，然后观察expr的工作，现在您已经有了足够的知识来修改该计算器代码，以添加支持这些函数的按钮。
Running the tests reveals that the results of the parser aren't yet in the AST types I created earlier (expr and its kin), but instead in a form consisting of Lists and Strings and such.
运行测试表明，解析器的结果仍不是我前面创建的AST类型(expr和它的亲属)，而是由List和String等组成的一种形式。
