Emacs Auto-Complete plug-in Ycmd

Emacs automatic completion, the best plug-in belongs to Ycmd. The following records my installation process.

1. Installing Ycmd Server

GitHub official address: Https://github.com/Valloric/ycmd

-Git clone ycmd to local ~/ycmd

$ git clone https://github.com/Valloric/ycmd.git ~/ycmd

-Install the necessary compilation tools and libraries

$ sudo apt-get install build-essential cmake python-dev

-Download the full submodule (big oh ... )

$ git submodule update --init --recursive

-Compile (slow oh ... )

$ CD ~/ycmd

$ ./build.py --all

once the compilation is complete, a Ycmd folder is generated in the current directory, and now it's like this ~/ycmd/ycmd

2. Install the Ycmd client and the necessary tools

-Open Emacs, command m-x list-packages, respectively install ycmd, Company-ycmd, Flycheck-ycmd

3. Configuration, add the following to ~/.emacs

There is a problem: the completion of the time, pop-up tip window, can not press TAB or Ctrl + N key to cycle option, can only continue to enter, until the first is to use, and then press ENTER to select. You need to know how to solve this problem, please tell me:P

Finish.
