emacs如何选择窗口以显示任何内容？

Question

The problem is, that I spent some time to open a view files, and display them next to each other on screen. I invested some time to balance the window sizes so they suit their content. And each window has some content that I need and don't want to search for again.

Now I do something in emacs. Mx command-<tab> for autocomplete:

• emacs rolls a dice
• on an even number emacs overrides an existing window with the possible auto completions. To select the window that needs to get rid of it's content, the dice is rolled again
• on an uneven number emacs splits an existing window and shows it's content there. The selection of which window to split, and weather to split it vertically or horizontally, the dice is rolled again.

Of course I am exaggerating here and this is not the true behavior, but it is how I feel emacs behaves. Is there any documentation that I can study so I can predict better how emacs behaves? I mean it's not just for autocompletion, it is also for commands that need to print something, or when I open files.

Answer 1

It can be complicated, as there's a lot of flexibility about this.

Honestly, I would just start reading the manual here, and follow the cross references:

Ch i g (emacs) Window Choice RET

Answer 2

For specifically suppressing the completions window, you could try shackle , which is available in Melpa.

(require 'shackle)
(setq shackle-rules '((completion-list-mode :ignore t)))
(shackle-mode 1)

It takes some work to make commands that manipulate the window layout do what you want, and there are a bunch of edge cases. I've gone from fighting it to trying to be zen about it. I just let Emacs do its thing and accept it for the most part, and use shackle or some other workaround for the window changes that I find extra annoying.
