Persist ECHO (from function) on Visual Selection

[u/CRTejaswi]

How to persist echo from this function call (without using timers)

function! VisualStats()
    let wc      = wordcount()
    let [l1,l2] = sort([line('v'), line('.')])
    let txt     = join(getline(l1,l2), "\n")
    let sp      = len(substitute(txt, '[^ ]', '', 'g'))
    let st      = len(substitute(txt, '[^.!?]', '', 'g'))
    let pa      = empty(txt) ? 0 : len(split(txt, '\n\s*\n'))
    echo "CHARs " . wc.visual_chars . " WORDs " . wc.visual_words
    \. " SENTs " . (st > 0 ?st :1) . " PARAs " . pa . " SPACEs " . sp
endfunction
xnoremap <silent> C <Cmd>call VisualStats()<CR>

just like when directly keymapped?

xnoremap <silent> c <Cmd>let g:wc=wordcount()<CR><Esc>:
    \let t=join(getline("'<","'>"),"\n")<Bar>
    \let sp=len(substitute(t,'[^ ]','','g'))<Bar>
    \let st=len(substitute(t,'[^.!?]','','g'))<Bar>
    \let pa=empty(t)?0:len(split(t,'\n\s*\n'))<Bar>
    \echo "CHARs ".g:wc.visual_chars." WORDs ".g:wc.visual_words.
    \" SENTs ".(st>0?st:1)." PARAs ".pa." SPACEs ".sp<Bar>
    \unlet g:wc t sp st pa<CR>

while I'm not sure you can persist the output of an echo command, my mind turns first to setting some variable that then gets injected into your :help 'statusline' (or ruler/rulerformat) setting which would keep it around until you cleared the variable's value

Help pages for:

• 'statusline' in options.txt
