Linux System vim Command parsing

The console version of Vim is released with Ubuntu, so there is no need to install it. However, if you prefer vim under the GUI interface, please install the VIM-GTK package from the new installation or enter it in the terminal: sudo apt-get install VIM-GTK

Vim needs to learn a lot of things. However, if you are familiar with VIM, you can use the advanced features of vim to manipulate the text very skillfully.

You can enter VIM in the terminal to start Vim in console mode, or enter Gvim to start vim in graphical mode. A blank screen with vim information will appear after the input. However, entering any text in this state will fail! So here are some of the features-patterns that many beginners will confuse.

[Edit] Mode

One of the most confusing features of Vim is that she has 3 modes.

Insert mode

Enter text

Edit mode

Executes the command, also known as normal mode.

Command mode

Execute colon command

Insert mode is not the default mode, you must press I to enter insert mode and enter some text on the screen. Press the <Esc> button to go from insert mode to edit mode. This pattern is used to move and manipulate text, sometimes in a very interesting way. Command mode is used to execute colon commands, such as Save, find/Replace, and configure Vim.

To save the text, you only need to enter in normal mode: Enter command mode and enter: W filename<enter> exit vim execute the colon command: Q. Summarize as follows:

Vim (start vim)

I (enter insert mode)

< Enter text >

<Esc> (back to edit mode)

: w filename (save file as ' filename ')

: Q (Exit Vim)

Vim filename (Opens the file you just saved in vim)

Keep in mind that the best way to learn vim is to use her, you can learn the basic use of vim through the built-in vim tutorial, just enter Vimtutor in the terminal (some systems may be vim-tutor).

Editing DocBook documents with vim

In order to submit an article to the Ubuntu document organization, you need to use the DocBook format. You may be interested in the Vim file type plugin Xmledit.

Add the following to ~/.VIMRC

map! , e <emphasis>

map! , P <para>

Map <F3> v/>^mx

If the cursor is at the top of an open XML tag, you can press F3 to cut the contents of the tag into the buffer. Move the cursor to the bottom of this section and press ' P ' (= paste) The content you just copied will appear after the current character.

This is useful for adding tags to already good documents. A typical use is to add formatting to a document copied/pasted from a Web page when needed.
