Summarize

The above are a few simple and commonly used vim configurations. Using vim to type programs requires the help of some plug-ins, such as:

• omnicppcomplete c/c++ code completion
• taglist View function list
• NERD_Tree View file list
• pydiction python code completion

For specific installation methods, please refer to google, baidu or visit http://www.vim.org. I won’t go into details here.

For those who are new to vim:
Vim is very powerful. If you want to use vim well, it is worth investing a certain amount of time to learn it. Just rely on the above configurations and plug-ins. far from enough. I recommend a textbook "vimbook" written by a foreigner. It is very detailed and does not contain much content. that’s all.
