在emacs中寻求自动完成功能 [英] seeking autocomplete functionality in emacs

问题描述

我正在寻找一个插件做自动完成弹出窗口的c ++开发在emacs。我尝试过的是Cedet语义和自动填充模式，他们在完成变量方面非常整齐和函数名，只要我已经有几个字。例如，我有一个类foo和一个函数返回一个整数1

I am seeking a plugin to do autocompletion popup for c++ development in emacs. what I have tried are Cedet Semantics and the Autocompletion mode, they are pretty neat in terms of completing the variable and function names as long as I have a few words already. For example, I have a class named foo and a function that returns an integer 1

class foo{
   int getInt(){return 1};
};

在main方法中，只要我开始输入

In the main method, so long as I started typing this

int main(){
 foo bar;
 bar.get...
}

这些插件没有问题像bar.getInt（）这样的建议。然而，我真正想要的是类似于Eclipse，只要我按点，可能的选择可以为我生成。这是可能在Emacs？感谢

the plugins have no problem popping up suggestions like bar.getInt(). However, what I am really looking for is something like in Eclipse, as soon as I press the "dot", possible choices could be generated for me. Is that possible in Emacs? Thanks

推荐答案

这取决于您的设置自动完成& CEDET。看起来自动完成设置仅在输入几个字符后才显示可能的完成。您可以检查 ac-auto-start 变量的值 - 如果这是一个数字，则在此字符数后调用自动完成。另一个重要的事情是你的 ac-sources 变量 - 对于使用CEDET，你需要使用 ac-source-semantic -raw 或 ac-source-semantic 完成源。
要在。或 - > 后自动完成，可以尝试使用Semantic的内置完成例如：

It depends on your settings of auto-complete & CEDET. It looks like that auto-complete is setup to show possible completions only after several characters will be typed. You can check value of the ac-auto-start variable - if this is a number, then auto-complete will be called after this number of characters. Another important thing is a what is in your ac-sources variable - for work with CEDET you need to use ac-source-semantic-raw or ac-source-semantic completion source. To automatic completion after . or -> you can try to use Semantic's built-in completion with something like:

(defun my-c-mode-cedet-hook ()
 (local-set-key "." 'semantic-complete-self-insert)
 (local-set-key ">" 'semantic-complete-self-insert))
(add-hook 'c-mode-common-hook 'my-c-mode-cedet-hook)
