When I open my .java file in vim, I could see a couple of lines prefixed with one / more ^I characters. It looks like tabs in Eclipse that has got converted into ^I.

I would like to replace a single ^I into spaces with 4 characters.

E.g

^I^I^I^IList<History> rulePackagesHistory = result.getHistory();

How can do that in vim editor?

Add these lines to your .vimrc:

set tabstop=4
set shiftwidth=4
set expandtab

After that, each new tab character entered will be changed to 4 spaces, old tabs don't. You must type:

:retab

This will convert all existing tabs in files to spaces.

If you don't want to use retab, you can use perl to replace each tab by 4 spaces:

perl -i.bak -pe 's/\t/    /g' file
0

For the specific file you can run the following while being in vim

You will need to press Ctrl+V+I to create ^I.

:%s /^I/^I^I^I^I/g

  • That is quite strange. I'm not sure if you used literal ^I or the one I explained in the answer – Valentin Bajrami Aug 21 '14 at 10:33
  • I guess command could be :%s /^I/[4spaces]/g – user648330 Aug 21 '14 at 10:38
  • Well, yes if you want to replace the tab ^I with spaces then you indeed put spaces there as :%s /^I/ /g In your example(question) You've 4 ^I^I^I^I which indicate tabs. – Valentin Bajrami Aug 21 '14 at 10:50
