How to switch to `flycheck-list-errors` buffer/window/minibuffer?

Question

For starters I use Doom Emacs.

Here's the scenario:

I have a python/perl/js buffer and flycheck-mode activated. Flycheck does its job and tells me that there are some errors that need attention. I go and do `M-x flycheck-list-errors (or SPC c x). I have 2 spaces now: One with my code (which I believe is a window) and another something (buffer/window/minibuffer?) with the list of errors.

Question is: How do I switch to that something without using the mouse?

I've tried next-buffer, previous-buffer, C-x o, and I simply don't know how to focus on it.

Appreciate your help as It's driving me crazy! It shouldn't be that hard, right?

Answer 1

You can either use M-x other-window to switch to the other window or create a custom function to use instead of the default function flycheck-list-error. The following function opens the flycheck-list-errors buffer and switches to it.

(defun switch-flycheck-list-errors ()
(interactive)
(flycheck-list-errors)
(pop-to-buffer "*Flycheck errors*"))

Answer 2

As you guessed, Doom emacs isn’t showing you the flycheck list in a window, which is why M-x other-window doesn’t help.

What can start to help is M-x list-buffers (C-x C-b by default) because of course it’s a buffer, just like everything else in emacs. Doom does show *Buffer List* in a window, so you can C-x o over to that, move the cursor to the *Flycheck errors* line, hit Enter, and pop over to that buffer. M-x other-window will work to get you back out, even though there’s no current window.

Faster than that—and you don’t have another new window or buffer to kill afterwards—is M-x pop-to-buffer which will accept *Flycheck errors* as an argument if that buffer is open.
