Make Vim show ALL white spaces as a character

I can't find a way to make Vim show all white spaces as a character. All I found was about tabs, trailing spaces etc.

Solution 1:

As others have said, you could use

:set list

which will, in combination with

:set listchars=...

display invisible characters.
Now, there isn't an explicit option which you can use to show whitespace, but in listchars, you could set a character to show for everything BUT whitespace. For example, mine looks like this

:set listchars=eol:$,tab:>-,trail:~,extends:>,precedes:<

so, now, after you use

:set list

everything that isn't explicitly shown as something else, is then, really, a plain old whitespace.

As usual, to understand how listchars works, use the help. It provides great information about what chars can be displayed (like trailing space, for instance) and how to do it:

:help listchars

It might be helpful to add a toggle to it so you can see the changes mid editing easily (source: VIM :set list! as a toggle in .vimrc):

noremap <F5> :set list!<CR>
inoremap <F5> <C-o>:set list!<CR>
cnoremap <F5> <C-c>:set list!<CR>

Solution 2:

As of patch 7.4.710 you can now set a character to show in place of space using listchars!

:set listchars+=space:␣

So, to show ALL white space characters as a character you can do the following:

:set listchars=eol:¬,tab:>·,trail:~,extends:>,precedes:<,space:␣
:set list

When you are finished, to hide the non-visible chars you would:

:set nolist

Solution 3:

:set list to enable.

:set nolist to disable.

Solution 4:

I think other answers here are more comprehensive, but I thought I'd share a trick I usually use to differentiate tabs and spaces visually:

:syntax on
:set syntax=whitespace

These are syntax highlighting rules for the Whitespace programming language - tabs show in green and spaces in red. :)

Can be combined with :set list as mentioned by many other answers, although the tabs will then show as ^I without a green higlight, but the spaces will show in red.
