This article mainly explains the "installation and basic configuration of vim under Ubuntu". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "the installation and basic configuration of vim under Ubuntu".

Installation and basic usage

1. Log in to Ubuntu with your root account, enter vim on the command line, and if it is not installed, you will get the following prompt:

The program "vim" is already included in the following packages:

* vim

* vim-gnome

* vim-tiny

* vim-gtk

* vim-nox

Please try:

The code is as follows:

Apt-get install

Follow the prompts to enter

The code is as follows:

Apt-get install vim

Install.

two。 After the installation is complete, typing vim will enter the standard mode of vim, then press I on the keyboard to enter insert mode and write something in it.

3. Press Esc to launch the insert mode and enter the standard mode, in which there are several basic commands to master.

Wq save and launch

I enter insert mode

X Delete the characters of the current cursor

Dd deletes the current row and saves the current line to the clipboard

P paste

: help view help for commands

Move the cursor up and down, left and right

4. Enter: W filename to save the file to the current directory.

5. Q exits the vim page.

6. The next time you type vim filename, you can edit or view the file.

Common plug-ins:

1.ctags installation

Ctags can build the index of the source tree, so that programmers can quickly locate functions, variables, macro definitions and other locations to see the prototype.

The following is the process of downloading, installing and configuring ctags under ubuntu:

Download and install ctags, enter commands at the terminal

The code is as follows:

Sudo apt-get install ctags

Build a source index. For example, I often need to consult the kernel code of Linux, which is placed in the / home/hjw951/arm/linux-2.6.12 directory.

Then after the terminal enters the directory, enter the command ctags-R *, and you will find that there is an extra tags file, which is the index file.

Register the path of the index file tags with vim, and enter gedit / etc/vim/vimrc at the terminal with the root user

Add a line at the end of the open file (of course, the specific path depends on your own situation)

Set tags=/home/user/arm/linux-2.6.12/tags

Then close the terminal and reopen it, and you can use VIM to view the function prototype of Linux anywhere.

2.taglist plug-in

People who must have used Source Insight will remember such a feature: SI can display macros, global variables, functions and other tag in the current document in the Symbol window, and click the above tag with the mouse to jump to the location defined by the tag; you can sort by alphabetical order, the class or scope to which the tag belongs, and the location where the tag appears in the file; if you switch to another file, the Symbol window updates to show the tag in this file.

The taglist plug-in in vim implements similar functions mentioned above, some of which are weaker than SI and some more powerful than SI. Moreover, the taglist plug-in is still in the process of improvement!

To use taglist plugin, you must meet:

Turn on the automatic file type detection function of vim: filetype on

The Exuberant ctags tool is installed in the system, and taglist plugin can find it (because taglist needs to call it to generate the tag file)

Your vim supports system () call

3.taglist installation

(1) create .vim in the user's home directory

The code is as follows:

[atom@localhost ~] $mkdir .vim

(2) decompress taglist_45.zip to .vim directory

The code is as follows:

[atom@localhost] $unzip taglist_45.zip-d. Vim

The directory structure after decompression is as follows

The code is as follows:

[atom@localhost] $ls-R taglist

Taglist:

Doc plugin

Taglist/doc:

Taglist.txt

Taglist/plugin:

Taglist.vim

(3) install taglist

[/ code]

[root@localhost atom] # cp / taglist/doc/taglist.txt / usr/share/vim/vim71/doc/

[root@localhost atom] # cp / taglist/plugin/taglist.vim / usr/share/vim/vim71/plugin/ [/ code]

(4) generate help tags

Enter the doc path of vim.

The code is as follows:

Cd / usr/share/vim/vim71/doc

Start vim and enter in command mode

: helptags. (. Indispensable, indicating the current directory. You can also start vim in any directory, as long as you specify: helptags usr/share/vim/vim71/doc/)

After you generate the help tab, you can view the taglist help using the following command

: help taglist.txt

Now you can try to open taglist in vim and enter the command

TlistToggle to open and close the taglist window (the command can be abbreviated to Tlist)

Introduction to the use of commands

Ctrl+]: jump to the place of the function definition where the function is called

Ctrl+t: return to the last location and the decompressed directory structure is as follows
