Remapping the oeprator to `d<space>` doesn't work.

[blasco]

I've tried to remap it:

let g:better_whitespace_operator='d<space>'

but this takes no effect, am I doing something wrong?

[Cimbali]

Maybe because the d command is already associated with the action to delete, so d<space> is read by vim as delete for a motion of just 1 character. That is why we made it start with <leader> − so that it would not conflict with existing commands.

[blasco]

But strange enough, if I modify the plugin manually it does work. So I went to the autolodaed script and changed it by d<space> and works. I think it would be best to provide an <plug>(delete-whitespaces-operator) that we can freely map like in other plugins. I'll try to implement that and provide a PR.

[blasco]

exe 'xmap <silent> d<space> :StripWhitespace<CR>'
exe 'nmap <silent> d<space> :<C-U>set opfunc=<SID>StripWhitespaceMotion<CR>g@'

That works perfectly fine

[Cimbali]

These should be exactly the commands that are run when g:better_whitespace_operator='d<space>' if they’re not mapped to anything else previously:

vim-better-whitespace/plugin/better-whitespace.vim

Lines 430 to 444 in a05c728

 if !empty(g:better_whitespace_operator) 
     " Ensure we only map if no identical, user-defined mapping already exists 
     if (empty(mapcheck(g:better_whitespace_operator, 'x'))) 
         " Visual mode 
         exe 'xmap <silent> '.g:better_whitespace_operator.' :StripWhitespace<CR>' 
     endif 
  
     " Ensure we only map if no identical, user-defined mapping already exists 
     if (empty(mapcheck(g:better_whitespace_operator, 'n'))) 
         " Normal mode (+ space, with line count) 
         exe 'nmap <silent> '.g:better_whitespace_operator.'<space> :<C-U>exe ".,+".v:count" StripWhitespace"<CR>' 
         " Other motions 
         exe 'nmap <silent> '.g:better_whitespace_operator.'        :<C-U>set opfunc=<SID>StripWhitespaceMotion<CR>g@' 
     endif 
 endif 

What do the mapcheck() commands return before you manually run those exe commands?

Closing for lack of activity. Feel free to reopen when new information is available, in particular with a minimal vimrc and verifying mapcheck() values
