Vim – Search Around Line Breaks

searchvim

When I am editing a LaTeX document in vim, often times I want to search for a phrase. Because I have LaTeX setup to wrap lines, sometimes half of the phrase will be on one line while the other half is on the next. In such a case, the search does not find what I'm looking for. So for example

blah blah blah hello
world blah blah blah

when searching using /hello world, I don't find what I'm looking for. Is there a quick and easy way to modify this search to get me where I want to be? Or better yet, a way to tell vim to match any white space (space, tab, new line) with a space in the search string?

After more searching, it looks like the easiest way to do this is with \_s. So for example:

/hello\_sworld

In general, an empty regular expression means to use the previously entered regular expression, so :%s//\1/g should do what you want.

Vim editing/switching between multiple files efficiently in large directory structures

It's possible to set up vim to edit multiple files without having to exit at all. You use multiple buffers and switch between them. Since you're using vim inside screen You can put the following in your ~/.vimrc to enable that.

   set hidden
   syntax enable
   source $VIMRUNTIME/menu.vim
   set wildmenu
   set cpo-=<
   set wcm=<C-Z>
   map <F4> :emenu <C-Z>
   nmap <Esc>[5D :bp<CR>
   nmap <Esc>Od  :bp<CR>
   nmap <Esc>OD  :bp<CR>
   nmap <Esc>[5C :bn<CR>
   nmap <Esc>Oc  :bn<CR>
   nmap <Esc>OC  :bn<CR>
   nmap <Esc>[3~ :bd<CR>
   nmap ZZ :bd<CR>

Those key mappings map to Ctrl-Left and Right arrow keys to switch between buffers. The F4 key invoke the same menu the GUI would show. Pressing tab also now displays a little menu for selecting the completion when your press tab.
