scrolling during search

[Tavis Ormandy]

Hello! I quite like the combination of incsearch and hlsearch, but hate
the way it scrolls the screen to matches -- I only want the hilights
without the scrolling.

I thought maybe I could fix this with autocommands, but I can't get it
to work, e.g.. I thought this might work:

autocmd CmdlineEnter / mark S
autocmd CmdlineChanged * normal g`S

But that doesn't do anything, any ideas?

Thanks!

Not sure if there is a way to do this currently. There actually is code
to restrict the matches to a line range, it is used for a command like
":1,30s/pat". So you could somehow fill in the line numbers at the top
and bottom of the window, type the pattern, then remove the text before
the pattern when starting to search. But that's an ugly hack.

I'm not against adding an option for this, but we currently have no
option to change how 'incsearch' works. Adding Yet Another Option?

Hah! I guess you mean something like this:

nno / :call feedkeys(":" . line('w0') . "," . line('w$') . "s /")<CR>
cnoremap <expr> <CR> (getcmdline() =~ '^\d\+,\d\+s /' ? "<Home><S-Right><C-U><Del><CR>" : "<CR>")

It's a bit scary, but it does sorta work! Do you think that will break
anything?

Naturally, I vote yes :)
