Re: Looking for a robust 'search for visual selection' implementation

In plugin/v_start.vim from lh-misc (https://github.com/LucHermitte/lh-misc/blob/master/plugin/v_star.vim), you'll find a version that leaves the register used untouched. However, the search register is modified, which is a feature.

This plugin uses lh#visual#selection() function from lh-vim-lib.

I can't tell about null bytes, I've never encountered them.

The complete code would look like:

xnoremap <silent> * <c-\><c-n>/<c-r>=escape(lh#visual#selection(), '/\^$*.[~')<cr><cr>
xnoremap <silent> # <c-\><c-n>?<c-r>=escape(lh#visual#selection(), '?\^$*.[~')<cr><cr>

function! lh#visual#selection()
try
let a_save = @a
normal! gv"ay
return @a
finally
let @a = a_save
endtry
endfunction

HTH,
