When using NERDTree, I often have the situation where I close all existing buffers

  • 0

When using NERDTree, I often have the situation where I close all existing buffers (except the NERDTree buffer), and then start opening fils from NERDTree again.

When doing this, NERDTree opens the files in a new split window, i.e. I have NERDTree at the left side, and on the right side two windows on top of each other, an emtpy buffer and the file I wanted to open.

What I want to happen is that NERDTree opens the file in the right window without splitting it.

Is there a way to tell NERDTree to never open a new window, if there is already one it could use? I tried using the “o” command, but that works exactly like the Enter command.

    I finally got around to look at the nerdtree code, and I found the fix for my problem: I had to change the plugin.

    I created a pull request for my changes on github:
    https://github.com/scrooloose/nerdtree/pull/102

    Update: Actually, the problem was a script I was using that set buftype=nofile for an empty buffer (it should set buftype=). After changing that, my problem went away.
