Learn about Vim

The current job is on the UNIX platform. It is usually written using the FTP function of UE.CodeSometimes the file size is too large, the transmission is very slow, and it is often not very stable.
I made up my mind to learn Vim (no one should use the original VI now). After two weeks of use, I found Vim is a very good editor, now I have installed Vim on windows, which is quite easy to use and has replaced ue.

The following describes some of my experiences in using VIM:
1. Make some settings before using Vim. Otherwise, you will be uncomfortable using it. The following is my configuration.

Here are some basic settings
If you have any questions, you can use the normal mode in vim.
: H keyword

2. Vim tutorial
We recommend that you first check the built-in tutor of VIM (this is a good teacher)
Start Vim with vimtutor
Or use H tutor in VIM to start
For Chinese tutorials, I recommend Li guozheng "everyone learns Vim".
Here is the vim key position. You can click it to view it at any time.

 
3. Vim plug-in
Several plug-ins are strongly recommended.
(1) A: switching between CPP and H files with the same name? Script_id = 31
(2) nerd_comments: Super annotation plug-in, supports many languages of the annotation style, according to the above settings, only need ", cc" can add a comment http://www.vim.org/scripts/script.php? Script_id = 1, 1218
(3) csupport: Write C/C ++ code essential http://www.vim.org/scripts/script.php? Script_id = 1, 213
(4) largefile: no longer have to worry about opening large files will slow the http://www.vim.org/scripts/script.php? Script_id = 1, 1506
(5) tipoftheday: Read more vim tips will have a lot of GAINS, remember to often update tips files ah http://www.vim.org/scripts/script.php? Script_id = 88
(6) cppomnicomplete: Provide the completion of class/object members in C ++ (vim7 is required) http://www.vim.org/scripts/script.php? Script_id = 1, 1520
(7) colorsamplerpack: provides hundreds of color themes, there will be a suitable for you, but most of them are in the GUI to have the corresponding effect of http://www.vim.org/scripts/script.php? Script_id = 1, 625
(8) vimcdoc: Hand Vim Help http://vimcdoc.sourceforge.net/

3. Use the vim color in Telnet.
If telnet is used in Linux, securecrt will automatically use the appropriate color to display vim different colors, but if it is in other UNIX, it will not be able to display the correct color, everything is in the same color.

Add in. vimrc (^ [the input method is Ctrl-V and then input ESC ):
If! Has ("gui_running ")
Set t_co = 8
Set t_sf = ^ [3% P1 % DM
Set t_sb = ^ [4% P1 % DM
Endif
Select ANSI for the simulated terminal type of securecrt and hook ANSI color to display different colors.

4. Vim's auto-completion Function
Generally, CTRL + N can be used to automatically complete. After vim7, C/C ++ functions, variables, or class members use Ctrl + X, CTRL + O can also be automatically completed. After cppomnicomplete is installed, you can use Ctrl + X, CTRL + O to complete the object.

5. Code folding
Many editors support code folding, and VIM is no exception.
Common shortcut keys
ZC folding code
Zo code for opening and folding
There are other shortcut keys to view help
: H fold

6. automatically format the code
In visual mode, press = to select the code.
In normal mode, press = to format the row where the cursor is located.

7. Script support
Vim not only has built-in script functions, but also supports extensions of VIM written in popular scripting languages such as Perl, Python, TCL, Ruby, and mzscheme.

Is Vim powerful?
After more than one year of testing, VIM 7.0 has also been release, so it is not easy to download and try again.

Happy vimming!

Users who are used to VIM but want to program in Windows
I also recommend
Viemu. You can simulate the VI editing operation in Visual Studio.
However, there is only a 30-day trial.
