CDT悬停显示文档 [英] CDT on hover show documentation

问题描述

在JDT中，如果我们悬停任何对象，如函数，类，变量等，eclipse将显示文档中的工具提示。当代码辅助窗口显示可能性时，还会显示此文档。

但是，CDT不会像这样工作。默认情况下，它显示了悬停对象的代码。在窗口中有一个设置 - >偏好 - > C / C ++ - >编辑 - > Hovers ，以选择要显示的文档，但不幸的是它没有显示任何内容。还有一个名为 libhover 的项目，但它似乎不适用于代码中doxygen注释。

有没有解决方案来模拟CDT中的JDT悬停行为？

解决方案

将LinuxTools插件安装到Eclipse C / C ++ IDE中

 帮助/安装新软件... /添加... 
名称= Linux工具
位置= http：//download.eclipse.org/linuxtools/update-3.2 
  

检查更新后的LinuxTools位置url

安装以下软件包，完成之后重新启动Eclipse。

• C / C ++图书馆API文档悬停帮助


• Newlib功能的Libhover


• 用于devhelp文档的库移动器帮助

您应该获得C标准库的工具提示功能如malloc，memset，printf。我刚刚在Windows 7中使用了 MinGW-builds_64bit 的Eclipse Luna（4.2.2）。 p>

我不知道C ++项目中发生了什么，我猜想我需要Doxygen技巧，我不熟悉。

In JDT, if we hover any object, like a function, class, variable etc, eclipse shows the documentation in a tool tip. This documentation is also displayed when the code-assist window shows the possibilities.

However, CDT does not work like this. By default, it shows the code of the hovered object. There's a setting in Window -> Preferences -> C/C++ -> Editor -> Hovers, to choose Documentation to be displayed, but unfortunately it does not show anything. Also there's a project called libhover, but it seems it does not work with in-code doxygen comments.

Is there any solution to mimic JDT hover behavior in CDT?

解决方案

Install LinuxTools plugin to Eclipse C/C++ IDE

Help / Install New Software... / Add...
Name=Linux Tools
Location=http://download.eclipse.org/linuxtools/update-3.2

Check for updated LinuxTools location url here

Install following packages, restart Eclipse after it's done.

• C/C++ Library API Documentation Hover Help
• Libhover for Newlib Feature
• Library Hover help for devhelp documentation

You should get tooltips for C standard library functions such as malloc, memset, printf. I just did this for Eclipse Luna (4.2.2) with MinGW-builds_64bit in Windows 7.

I don't know what happens in C++ projects I guess it needs Doxygen tricks which I am not familiar with.
