This is where I got my inspiration. Note the exact
same credits. But I found the mappings so
illegible that I rewrote them as functions.
I don't find using a function to be much of a
"con" compare to the "pro" of legibility. The
function I posted today has already been hacked
and made better. It would take much more time and
thought to modify these monsters...
Reading the comments at the top, I thought for a
minute that the mapping could search for a
blockwise visual region. That would be pretty
neat.

I know you have had lots of different reponses on this thread.
This is what I keep in my vimrc, which doesn't use a function.
Simply highlight the text and hit * or #, just like you would for a given
work in normal mode.

I have learned a lot from this thread!
I changed the function slightly (see below) because I also
didn't understand the missing ^M was causing my problem.
I like to use * and # for searching for a string in highlight
mode, then I press F10 to turn off highlighting. However,
pressing F10 with nohls highlights the word under the cursor
without searching for it, which was is a modification of some
comments at the bottom of vimtip #1.
Between this thread and the discussions in vimtip #1 I now
have the following which works really *really* nicely:
"begin
" disabled initially since it distracts me
set nohlsearch
" in normal mode, make * highlight the search string
nnoremap * *:set hls
nnoremap # #:set hls
" in visual mode, use highlighted selection for search pattern
vnoremap * :call VisualSearch('f'):set hls
vnoremap # :call VisualSearch('b'):set hls
function! VisualSearch(direction)
let l:saved_reg = @"
execute "normal! vgvy"
let l:pattern = escape(@", '\/.*$^~[]')
let l:pattern = substitute(l:pattern, "\n$", "", "")
let @/ = l:pattern
let @" = l:saved_reg
if a:direction == 'f'
normal n
else
normal N
endif
endfunc
" map to toggle the highlight search mode
" if hlsearch is on then simply turn it off
" if hlsearch is off then highlight word under cursor only
nnoremap :call SetSearchReg():set invhls
function! SetSearchReg()
if &hlsearch == 0
let @/ = expand('')
endif
endfunc
" my mind/fingers think of as highlight search mode
" so make visual mode and work like * and #
vnoremap :call VisualSearch('f'):set hls
vnoremap :call VisualSearch('b'):set hls
"-end-

Whether or not search items are highlighted
depends on the value of the 'hlsearch' option.
The search item gets highlighted on my end when the
option is set. Is yours set?
:set hls?
This is quite strange, it is set, i.e.
:set hls?
returns
hlsearch
If I use your visual selection when I first launch gvim, then it works
with the highlighting. If I then use to clear the highlighting
according to this line in my .vimrc that I gave before:
:nnoremap mz:nohlsearch/`z
then the highlighting is no longer displayed as is expected.
If I then do
:set hls?
again, I get again:
hlsearch
but if I use your visual selection tool again then this time I get no
highlighting. Of course if I set hls again using :set hls then it works
fine again until I press enter.
So what I was thinking was just to add a :set hls at the start of your
function, then it should alway highlight the searched for items, however
I tried variations on including it but no nothing about scripting so
they didn't work, can you tell me how I should add it? I tried the below
but it didn't work.

I agree with what you say below completely, I just didn't express myself
clearly enough in the paragraph above, I was just telling you the
actions I had performed and it appears I should have been pressing * or
# not / or ? as I originally thought, but the lack of the literal
newline was causing it not to work too.
Well you could do it with "/" and "?" but I like
to keep their behavior intact as it is useful to
extend the visual region.
I remapped "*" and "#" instead, as shown in these
lines:
vnoremap * :call VisualSearch('f')
vnoremap # :call VisualSearch('b')
I prefer that because these don't have any special
meaning in visual mode and it ties in nicely with
the "search next/previous word" function they have
in normal mode.
Thanks for your help,

I think the original included raw CR characters in the two :execute

in my copy of Jean-Rene's note). I think your e-mail client broke the

Everything seems to work fine now, except the searched for items aren't
highlighted like they normally are when I search, is there a simple
reason or am I just asking for too much, sorry I can't sort this out
myself, but I don't understand the function well enough to see a
possilbe reason, the only thing I could think of that might cause it
would be this in my .vimrc
" Clears search highlighting by just hitting a return.
" The clears the command line.
" (From Zdenek Sekera [EMAIL PROTECTED] on the vim list.)
" I added the final to restore the standard behaviour of
" to go to the next line and the mz and `z to return the cursor to its
" precommand position
:nnoremap mz:nohlsearch/`z
However, if this were interfering it would clear the command line as
well and I don't see that so it can't be the cause.
Thanks,
Rob.
