function! DebugC()
    let l:debugStr = "printf(\"" . s:debugPrefixStr . s:debugCounter . "\");"

    if g:debugstringAlwaysIncludeHeader
        let l:incStr = "#include <stdio.h>; "
        let l:debugStr = l:incStr . l:debugStr

endfunc " }}}

Method dumps the text correctly but if I use execute instead of call, it always moves the cursor to the top of the

" doesn't move to top of file
autocmd Filetype c,cpp nnoremap <buffer> <silent> <Plug>DumpDebugString  :call DebugC()<CR>

" moves cursor to the top of the file
autocmd Filetype c,cpp nnoremap <buffer> <silent> <Plug>DumpDebugString  :exe DebugC()<CR>

Adding getcurpos(), setpos() at the start and end of the function doesn't seem to solve the problem.

Any pointers?


In vim, a function which does not explicitly return a value actually returns 0. So, your code is equivalent to exe 0, which is like :0 meaning move the cursor to the first line.

  • Wow, so troublesome, yet so simple of an explanation! So I get I can solve it just by return getcurpos()[1] + 1 or something like that.. Do you think there is a more elegant solution to the problem? – bergercookie Jan 1 '18 at 19:41

    Is there a reason you are using exe instead of call? It is not clear from your question why call doesn't work. And you can just return empty string '', exe '' should do nothing. – Mass Jan 1 '18 at 20:02
  • The actual call is a little more complicated, something like this: autocmd Filetype c,cpp nnoremap <buffer> <silent> <Plug>DumpDebugString :<C-U>exe <SID>debugFunctionWrapper("s:debugC")<CR> You're right on the second remark though, returning ' ' does the job... – bergercookie Jan 1 '18 at 20:05
  • You can use call in that example. Actually, :<c-u>call s:function()<cr> works too. But, the alternative solution, if required, is just return empty string return '' in debugFunctionWrapper. – Mass Jan 1 '18 at 20:11
  • Ah, yeah you're right again.. call does work in this case as well.. Thanks again! – bergercookie Jan 1 '18 at 20:17
