Ubuntu vim is configured as a c++ development editor

The overall vim setup is in /etc/vim/vimrc. If you want to set the configuration for all users, you can set it in the same way as.vimrc. Add the following statement at the end.

Do not modify the /etc/vimrc file. Each user can set vim in the root directory and create. Vimrc. The command is as follows:

vim ~/.vimrc
Copy the code

By default, when vim is used for editing, the editing interface does not display the line number, syntax high brightness display, intelligent indentation and other functions. To work well with Vim, you need to manually set up a configuration file:.vimrc. Many plug-ins need to be installed to complete the functionality.

The VIM configuration has the following advantages:

1. Press F5 to directly compile and execute C, C++, and Java codes and shell scripts. Press F8 to debug C and C++ codes

2. Automatically insert file header, automatically insert table header when creating C and C++ source files: including file name, author, contact information, establishment time, etc., readers can change according to their needs

3. Map Ctrl + A to select all and copy shortcut keys to facilitate code copying

4. Press F2 to eliminate blank lines in the code

5. Press F3 to list the files in the current directory and open the tree file directory

6. Supports mouse selection and arrow key movement

7. Code highlight, auto indent, show line number, show status line

8. Press Ctrl + P to automatically complete information

9.[], {}, (), “”, ‘ ‘and so on are automatically completed

10. Other features Readers can study the following documents
