Switching to VIM window by name

Question

There are some excellent Vim plugins for switching to a specific file or buffer by typing part of the name. Does anyone know of a plugin like these that allows for quickly switching between open windows?

For example, if I had a vsplit with a file named 'a.txt' on one side and 'b.txt' on another I'd like to be able to switch between them by typing the filename (or just 'a' or 'b' with incremental searching). This might not be too useful for two windows, but I often have up to 5 windows open, so switching between them using the normal navigation buttons can be a pain.

WinWalker seems to support this type of functionality, but wrapped inside of a much larger framework for window navigation.

Answer 1

:b does that happily if you have :setswitchbuf+=useopen (in your vimrc). It supports file name completion, e.g. with Ctrl-D.

Answer 2

@Aaron Thoma' s answer with switchbuf+=useopen did not work for me. Actually the doc does not mention that the setting is supported by :b comand.

I've used the following snippet:

let windowNr = bufwinnr(pattern)
if windowNr > 0
  execute windowNr 'wincmd w'
endif  

See bufwinnr()
