VIM：如何获取当前窗口大小，以便将NEEDTree设置为1/3窗口大小？

Question

I wish when I bring out NEEDTree or TagBar, the window size is always 1/3 of my original vim window size, no matter how big my vim window is, it's calculated automatically.

How to do this?

Answer 1

vim has built-in function winwidth({nr}) to get window width. If you pass a zero as win number, it will return your the width of current window.

To change the window size of NerdTree, you have to set the variable: NERDTreeWinSize
