Vim quick learning

Ctags
Built-in CTAG plug-in VIM
Run $ ctags-R in the current project directory shell to recursively generate a tags file in the current directory
Run: Set tags = tags // in VIM to specify the current directory as the file to be read

Run: version in VIM to view a lot of information about Vim itself.

 

The sequence in which Vim reads the vimrc configuration file. When Vim is opened, the user vimrc is searched in the above sequence, and the commands in the first user vimrc are executed, ignoring other users vimrc. In vimrc, it is actually executed in sequence.

If you use the "vim-U filename" command to start vim, the specified filename will be used as the vim configuration file (useful when debugging your vimrc );

If you use the "vim-u NORC" command to start vim, you will not read any vimrc file: If you suspect that your vimrc configuration is incorrect, you can skip vimrc execution in this way.

View the tags file. You can see that the file locates functions and variables in each file. If no, it cannot be found.

Use ctags:

CTRL +] Jump to the specified function

CTRL + T and CTRL +] commands are opposite

: Tags can display jump depth details such:

2. Vim shortcut

": Tag func_name" jumps to function func_name. When using the tag command, you can use the tab key to perform matching search and continue to switch down by pressing the tab key.

Vim shortcut:
% Jump to the matching brackets ("{}" "[]" "()"). It can also match if Else.
CTRL + I, Tab jump to the next hop

CTRL + O jump to the previous hop point
# Search for the entire keyword from the cursor (exact match search)

G * search for all words that contain the current word

W jump to the start of the next word
E. Jump to the end of a word.
B Jump backward

CTRL + G lists the positions and columns of the cursor

"." Repeat the previous Modification
CTRL + R opposite to u
Y Replication
YY copy a row
GF jumps to a file (GF uses a string as a file and recursively searches for it in the current folder)

Visual mode operation:
CTRL + V enter block-Based Visual Mode
V enters the character-based Visual Mode
V enters the line-Based Visual Mode
C. Delete the selected block

CTRL + z sleep Vim
FG num returns Vim

FX: Search backward and move the cursor to the next X of the current row. Obviously, X can be any letter and can be repeated ";".

^: Move the cursor to the first letter of the current row.
$: Move the cursor to the end of the row.
): Move the cursor to the next sentence.

MA: Mark a bookmark at the position of the current cursor. Its name is. Only lowercase letters are allowed. You can't see the existence of bookmarks, but it does

It's already there.
'A: To bookmarks. Note that this is not a single quotation mark. It is generally located on the left of 1 of most keyboards.

(C and D are used in a similar way, but they are inserted in or out of the insert mode)

 

Vim is an excellent editor for writing code, because it has some features dedicated to programmers.
Here are some common examples:
