Vim Editor---Bulk comments and anti-annotations

When writing code using VIM, it is often necessary to use bulk annotations and counter-comments for a piece of code. The following is a brief description of its operation.

Method Piece Selection Mode

Insert Comment:

Enter virtual mode with V

Use the up and down keys to select the number of lines you want to comment

Press Control+v (win below ctrl+q) to enter the column mode

Press the larger "I" into insert mode, enter the comment "#" or "//" and press ESC immediately (two)

Uncomment:

Ctrl + V Enter block selection mode, select the comment symbol for the beginning of the line you want to delete, note//To select two, then press D to delete the comment

Method Two replace command

Bulk Comment:

Use the following command to add comments at the beginning of the specified line:

: Starting line number, ending line number s/^/comment/g

Uncomment:

: Starting line number, ending line number s/^ comment//g

Example Demo:

Add//comment on line 27-30

: 27,30s#^#//#g

Delete//comment on line 27-30

: 27,30s#^//# #g

Add # comments To line 10-20

: 10,20s/^/#/g

Delete # comments on line 10-20

: 10,20s/^/#/g

Note that in the example, the delimiter used is the opposite symbol, and if the match//is used #作分隔符这样不需要对/as Escape, save the number of inputs.
