Vim has some options such as retab that can be used to indent and convert all the files processed by vim. However, it is so brutal that we do not want vim to automatically process all the files.

 

 

 

Therefore, it is more appropriate to manually perform the conversion. You can use the following command in vim:

 

 

 

View plain

: % S // \ t/g

 

Explanation:

 

The colon at the beginning is mandatory for executing commands in vim. Just like '/' is the start of the search command.

 

% S indicates replacement.

 

The first '/' indicates the content to be replaced (four consecutive spaces)

 

The second '/' indicates the content to be replaced with (here '\ t' is the tab)

 

The third '/' indicates the replacement option ('/g' indicates full-text replacement)
