如何在Xcode 9.3中显示C ++代码文档？ [英] How can I show C++ code documentation in Xcode 9.3?

问题描述

我正在Xcode中开发基于C ++的软件，并且希望（至少）与我为Swift或objc开发一样方便（至少）。

示例：

  std :: string myString（ hello ）; 
 if（myString.empty（））{
 //做某事
} 
  

如果我想确切地知道 .empty（）的功能，我想按住Option键并单击该函数，并获得包含来自例如以下信息的文档覆盖

解决方案

您不能。根据 Apple的Xcode发行说明，，自Xcode 8.3起

第三方文档集支持已弃用，不再是$ b Xcode的未来版本中支持$ b。 （30584489）

还有其他文档浏览器，例如 Dash 允许您安装自己的文档。但这并不能满足您的期望。

我已经验证了将C ++。docset添加到〜/ Library / Developer / Shared / Documentation 不起作用。 （可能是早期Xcode留下的目录）实际上，完全删除此目录不会影响Xcode 9.x正确显示默认文档。

I´m developing software based on C++ in Xcode and want to have (at least) the same convenience for code documentation as if I was developing for Swift or objc.

Example:

std::string myString("hello");
if (myString.empty()) {
    // do something
}

If I want to know exactly what .empty() does, I would like to Option-Click on the function and get the documentation overlay with information from e.g. http://en.cppreference.com/w/cpp/string/basic_string/empty, exactly as it does for objc and Swift.

How is this possible?

Current output just looks like this:

解决方案

You cannot. According to Apple's Xcode release notes, as of Xcode 8.3

3rd party docset support is now deprecated and will no longer be supported in a future release of Xcode. (30584489)

There are alternate doc browsers, like Dash which allow you to install your own documentation. But this does not give you what you're hoping for.

I have verified that adding a C++.docset into ~/Library/Developer/Shared/Documentation does not work. (likely a directory left over from an earlier Xcode) In fact, removing this directory entirely does not affect Xcode 9.x from correctly displaying the default documentation.
