Vim count selection and put in statusline

[carlosp]

Dear all, I would like to know if there is some non-baroque way of, when
doing a selection of some text, set in the status line just the number of
characters in the selection (and of course, when one modifies the selection,
as moving the coursor in the visual mode) the status line should be updated
automatically. The solutions that occurred to me involve using external
commands (like wc -l) and then sending that to vim, each time I move the
selection etc. Does anyone knows a clean way of doing such a thing?

Thanks!

It is not exactly what you asked for, but when you set 'showcmd',
Vim already displays the size of the visual selection.

See :h 'sc'

Thanks a lot Christian. Indeed that is not exactly what I ask for, but is
very very close. That shows me the number of lines. Anyone knows how to
"program" such a behavior? I have never browsed through the vim source code,
I wonder if one would get inspired or totally confused...

put the following function in your .vimrc or in a file named
~/.vim/plugin/VisualSelectionSize.vim

function! VisualSelectionSize()
if mode() == "v"
" Exit and re-enter visual mode, because the marks
" ('< and '>) have not been updated yet.
exe "normal \<ESC>gv"
if line("'<") != line("'>")
return (line("'>") - line("'<") + 1) . ' lines'
else
return (col("'>") - col("'<") + 1) . ' chars'
endif
elseif mode() == "V"
exe "normal \<ESC>gv"
return (line("'>") - line("'<") + 1) . ' lines'
elseif mode() == "\<C-V>"
exe "normal \<ESC>gv"
return (line("'>") - line("'<") + 1) . 'x' . (abs(col("'>") - col("'<")) + 1) . ' block'
else
return ''
endif
endfunction

and then change your 'statusline' option so that it contains

%{VisualSelectionSize()}

at an appropriate place, e.g., with

:set statusline.=%(\ %{VisualSelectionSize()}%)

you would append it to your current status line. The group %(...%) takes
care of removing the space if VisualSelectionSize() returns an empty
string when you are not in a visual mode.

Thanks a lot Jürgen! I will try it later and modify it to fit exactly my needs.

I use the default vi settings for status line.. and it does show me the number of selected characters in status line on right side.. As I keep selecting the characters in visual mode it keeps updating the selected characters in status line.

Thanks,
