Neotree window permanently resizes other windows

Question

I usually have my emacs frame something like this:

|             |             |
| <window 1>  | <window 2>  |
|             |             |

When I open neotree, it then looks like this (N representing the neotree window):

|   |             |         |
| N |     W1      |   W2    |
|   |             |         |

Then, when I close neotree, the windows look like this:

|                 |         |
|         W1      |   W2    |
|                 |         |

This is aesthetically displeasing and brings window 2's width below 80 characters, so code lines wrap.

Is there a way I can make neotree-toggle reset the window sizes to their values in the first diagram?

Answer 1

Very strange. I don't have this problem. Here my conf:

(autoload 'neotree "neotree" "" t) 
(setq neo-window-width 50) 
(setq neo-persist-show nil)

I use emacs 25 with the latest neotree.el

Answer 2

Here's the workaround that I use:

• set a hotkey for neotree-toggle: (global-set-key (kbd "M-n") 'neotree-toggle)
• open 2 or 3 windows side by side: C-x 3
• make them the same size: C-x +
• open neotree: M-n

Additionally, I started using winner-mode, mainly for maximizing windows: C-x 1, then revert to previous window configuration C-c <left>.
