Vim (4) -- plug-in (plugin)

I think Vim is a powerful text editing software because it supports function expansion in the form of plug-ins (plugin. Many Vim enthusiasts write plug-ins to implement the required functions and customize their own vim. Vim supports the following types of plug-ins:

• Vimrc: vimrc is similar to a configuration file. When Vim is started, content is read and configured accordingly. In vim, you can set vimrc and gvimrc in two files. Vimrc is used for some common settings, and gvimrc is used for GUI-related settings. They are located in the vim installation directory.
• Global Plugin: used to provide global or general functions. Vim provides some global plug-ins by default during installation. These plug-ins are located under <Vim installation directory>/<$ vimruntime>/plugin. You can also install some plug-ins to store them in your own plug-in directory, for example, on Linux/MacOS, the <Vim installation directory> /. vim/plugin/, which is the <Vim installation directory>/vimfiles/plugin/on Windows (note that the plug-in folder may need to be created by yourself ).
• File Type Plugin: used to support specific types of files, such as C and XML files. Similar to the global plug-in, VIM provides some default file type plug-ins, and allows you to install some file type plug-ins on your own. The storage location of file-type plug-ins is similar to that of global plug-ins.
• Syntax highlighting plug-ins: store the plug-ins that provide syntax highlighting support for some languages under <Vim installation directory>/<$ vimruntime>/syntax/, such as C. vim, Python. vim. To use these plug-ins, you may want to execute: Set filetype = language in Vim, for example: Set filetype = python.
• Compile plug-ins: Compile plug-ins. As the name suggests, they are compiled in some languages that can be compiled directly in Vim.ProgramSupported. These plug-ins are stored in <Vim installation directory>/<$ vimruntime>/Compiler.

The following describes some common vimrc setting commands.

 Set nocompatible  "  Explictly get out of vi-compatible mode  
  
Set background  =  Dark  "  We plan to use a dark background  
  
Syntax on  "  Syntax highlighting on  
  
Set number "  Turn on line numbers  
  
Set ruler  "  Always show current position along the bottom  
  
Set incsearch  "  Do highlight as you type you search phrase  
  
Set ignorecase  "  Case Insensitive by default  
 
Set smartcase  "  If there are caps, go case-sensitive  
  
Colorscheme macvim  "  The color scheme I am using now 

Here we only list some of the most common setting commands for beginners of vim. There are also a lot of vim setup commands you can't imagine. I believe you can find them online. We recommend two templates here to find your favorite VIM: http://www.vi-improved.org/vimrc.php and http://amix.dk/vim/vimrc.html.

Finally, let's preview: in the next section, I will introduce how to use the various plug-ins introduced in this section to create a python IDE.
