Use the vim editor and the vim editor.

I. Introduction

　1. vim is a powerful text editor. If you are familiar with it, it will effectively help us improve the efficiency of editing text and programs. The vim editor has a relatively high threshold for getting started. Many people are reluctant to remember many commands, which are often discouraged in the early stages of learning.

2. vim learning requires constant practice and use. Only by forcing itself to continue using it can we remember the seemingly complex commands in the Process of use. However, if we get used to the vim editing mode, we will feel that vim will really help us improve the efficiency of text editing.

3. For vim learning materials, the vim Help documentation provided in this document is rich enough for constant reference during the learning process. In addition, there is also a simplified starting document, namely vimtutor. You can enter vimtutor in the command line to start learning and finish learning in less than an hour.

Ii. Configuration

1. vim configuration files include global configuration (usually in the/etc/vim/vimrc directory) and personal configuration (/home/username /. in vimrc), the global configuration file takes effect for all users in the system, and the personal configuration file takes effect only for the user's own use environment.

2. The vim configuration file is usually configured on the Internet by someone else. You can copy it to your personal configuration file and use it directly. You can also customize your own environment as needed.

3. Configure scripts

　　1. In the previous use process, I have configured a configuration script based on my personal needs. Most of the configuration scripts are annotated and can be configured as needed. Note: "beginning to indicate comments in vimrc

2. vim topic Configuration

Vim comes with many theme settings. You can view the current version of vim color scheme in the/usr/share/vim/vim72/colors directory. in vimrc, use colorscheme darkblue or its topic to configure the vim topic.

You can also configure different or slightly complex color schemes according to the script. The following script configures the vim color scheme based on different time periods of each day.
