使用 OCaml 在字符串中嵌套引号? [英] Nested quotes in string with OCaml?

问题描述

我一直试图将一个字符串作为参数传递，其中包含双引号.例如，我希望输入是一个字符串，表示我正在OCaml"中编程:

I have been trying to pass a string as an argument that has double quotes in it. For example, I want the input to be a string saying I am programming in "OCaml":

"I am programming in "OCaml""

这就是我希望能够通过的.我尝试使用一些词汇约定，但没有运气.我不想更改 OCaml 周围的引号.

That is what i want to be able to pass. I tried using some lexical conventions but had no luck. I don't want to change the quotes around OCaml.

我试过了

"\"I am programming in "OCaml"\"

还有一些变体.关于如何通过它的任何提示?

And a couple of variations of this. Any tips on how to pass it?

推荐答案

你应该转义字符串里面的引号，就像任何其他需要转义的字符一样，而不是分隔符本身:

You should escape the quotes inside the string, as with any other character that needs escaping, not the delimiters themselves:

"I am programming in \"OCaml\""

或者，您可以使用带引号的字符串，它不需要(或允许)转义，并且可能更接近您想要的:

Alternatively, you can use a quoted string, which does not require (or allow) escaping and might be closer to what you were trying for:

{|I am programming in "OCaml"|}

有关详细信息，请参阅有关字符串文字的部分在 OCaml 手册中.
