Vim common shortcut key Configuration

Vim common shortcut key Configuration

In Linux, when you use VI to write C/C ++ programs. h. CPP. CC and other files sometimes have many similar operations. If we need to complete the input for each similar operation, it will reduce the efficiency of writing programs. Simple configuration, that is, you can use common shortcut keys, which will be the prerequisite for Happy program writing.

Now, the simple configuration records when I write a program using Linux VI are as follows:

If you configure Vi, you need to use a vimrc file. Under the/etc directory, there is a vimrc file that can be configured. In this case, all users logging on to Linux can share these configurations. However, we may not be able to obtain the permission to edit the/etc/vimrc file, so we still need to configure the current user's vimrc.

When we use an account to log on to the Linux system, that is, out of the current user's home directory, each user has its own Vim configuration file, namely. vimrc. We can use

Cd ~

Enter the current user's home directory, and then use

Ll-A. vimrc

Command to check whether this file exists. If it does not exist, we can create this file.

Vi. vimrc

Then we can perform the following settings:

Line 3 enables syntax highlighting.

Row 2nd is the line number that opens vi

Row 3 sets the tab in VI, that is, the size of the tab key.

6th ~ The eight lines are our customized shortcut key settings for C/C ++ programming.

When writing a program, input

. I

Then press enter to display # include <iostream>

This reduces the burden on writing code.

In addition, paste a piece of configuration found on the Internet
