preface

This article mainly introduces the method of inserting number sequence in vim, and shares it for your reference and study. Let's start with a detailed introduction.

Text to be processed

Let's say that the original text is 


 This is the first 1 line 
 This is the first 2 line 

 This is the first 4 line 
 This is the first 5 line

The insert line number becomes 


1  This is the first 1 line 
2  This is the first 2 line 
3
4  This is the first 4 line 
5  This is the first 5 line

There's one other desired effect 


 This is the first 1 line  line[1]
 This is the first 2 line  line[2]

 This is the first 3 line  line[3]
 This is the first 4 line  line[4]

Both of the above requirements are answered below, and more complex number sequence insertions can be achieved using the method mentioned below. Includes replacing the specified character, followed by a sequence of Numbers.

Use the line ()

line('.') You can return the current line number 


:g/^/s//\=line('.').' '/

Very simple, but not very flexible, and can only be used to display the line number of the current row

Use the ex command

vim provides 1 ex commands to print line Numbers, such as "=", "p #", "#"

To get the command output from vim, you need to use redir 


" For the former 5 Row plus row number 
:redir @a | 1,5#|redir END
:1,5d | put! a |1d |6d

There is an extra line before and after pasting, so use d to delete it

Use range, setline, getline

range（） A list of numeric sequences can be generated 


:for i in range(6)
:call setline(i, i.' '.getline(i))
:endfor

range(6) A list of Numbers 1-5, not 6, is generated

Variable volume plus 


: let i=1 | g/^/s//\=i.' '/ | let i=i+1

This approach is more flexible and allows you to control the values inserted by controlling the value variation of i

Macro and Ctrl - A

You can increment the number by pressing ES73en-ES74en and ES75en-ES76en by 1

The process is as follows:

Manually add the sequence number and space on line 1 Enter 0"ayw to put the sequence number and space in register a Move to the next line and execute the following key 

qz0"aP0^A"ayawjq

perform 4@z To execute the sequence of commands saved in register z on the following four lines

The above command sequence is explained in detail below

qz: Start recording the macro and save it in register z 0: Move to the top of the line aP: Paste the contents of register a (line number and space) here 0^A: Move to the beginning of the line and press ES97en-ES98en to add 1 to the number under the current cursor "ayaw: Copy word under current cursor to register a j: Move to the next line q: End of recording

If there is no space for the flag, then aw cannot be used to copy an word; v is used to select the corresponding numeric portion

Note: at the command line, ES111en-ES112en requires ctrl-ES114en, ES115en-ES116en to represent this key

Macros are more powerful under vim, but it usually takes a lot of debugging to write a workable macro

External command

seq is the command that outputs a sequence under linux 


harriszh Sat 22:14@ ~/trunk/go$ seq 5 -2 1
5
3
1
harriszh Sat 22:14@ ~/trunk/go$ seq 1 5

For three parameters, the intermediate parameter is step, and the two parameters are the starting and ending Numbers. step is 1

through r !seq 1 5 To insert a sequence of Numbers in a file, and then copy it using column mode

Using printf

Insert the line number directly 


:%s/^/\=printf('%-4d', line('.'))

Where - is left aligned, the default is right aligned

Inserts a sequence at the specified row

First, V selects the block to insert the serial number 


1  This is the first 1 line 
2  This is the first 2 line 
3
4  This is the first 4 line 
5  This is the first 5 line
0

Insert sequences only on non-blank lines

Put func below into.vimrc 


1  This is the first 1 line 
2  This is the first 2 line 
3
4  This is the first 4 line 
5  This is the first 5 line
1

a:0 The equivalent of argc , a:1 The equivalent of argv[1]

g:i is the global variable i

Then select the appropriate block 


1  This is the first 1 line 
2  This is the first 2 line 
3
4  This is the first 4 line 
5  This is the first 5 line
2

range and print

The following three commands all insert sequences below the specified line 


:12put = range(1,5)
:call append(12, range(1,5))
:0put = range(3,7)

The first command is equivalent to the second command

0put, just before line 1

range and print combine to output formatted results 


1  This is the first 1 line 
2  This is the first 2 line 
3
4  This is the first 4 line 
5  This is the first 5 line
4

v:val represents the values retrieved from the previous list

Using for directly is easier to understand 


1  This is the first 1 line 
2  This is the first 2 line 
3
4  This is the first 4 line 
5  This is the first 5 line
5

A sequence number is appended to a particular character 


1  This is the first 1 line 
2  This is the first 2 line 
3
4  This is the first 4 line 
5  This is the first 5 line
6

The problem with the above command, however, is that if there are multiple abc on line 1, they will all be replaced with one number and not incremented

To solve the above problem, use registers 


1  This is the first 1 line 
2  This is the first 2 line 
3
4  This is the first 4 line 
5  This is the first 5 line
7

setreg() returns 0, so use the above method to call setreg to update the value of register a

vim8 ctrl - a

vim8 offers new features for Ctrl-ES233en

Such as the 


my_array[0] = 0;
my_array[1] = 0;
my_array[2] = 0;
my_array[3] = 0;
my_array[4] = 0;
my_array[5] = 0;
my_array[6] = 0;

Select 0-0 with COLUMN ctrl-V, then press g ES243en-ES244en,

Select the preceding columns 0-6, and then press g ES249en-ES250en, too

The end result is 


1  This is the first 1 line 
2  This is the first 2 line 
3
4  This is the first 4 line 
5  This is the first 5 line
9

g Ctrl-A It works by adding 1 to the first number, 2 to the second number, 3 to the third number...
