problem:
key bindings that use the winum package,
don't work in the spacemacs-base distribution.
for example in the buffer transient state: SPC b .
{number}, C-{number} or M-{number}
shows messages like these:
Wrong type argument: commandp, winum-select-window-1
Symbol’s function definition is void: winum-get-window-by-number
cause:
the winum package is loaded in the spacemacs-navigation layer,
but the layer isn't used in the spacemacs-base distribution.
solution:
show the message:
This command requires the winum package,
winum is part of the spacemacs-navigation layer.
Problem:
`C-x w 0` calls `winum-select-window-0-or-10` which shows:
winum-select-window-by-number: No window numbered 10
Solution (Thanks Miciah):
Remap `winum-select-window-0-or-10` to the current filetree command:
`neotree-show` or `treemacs-select-window`
Then all three key bindings:
`C-x w 0`, `SPC 0` and `M-0` will call the same filetree command.
Additionally:
Renamed the remapped which-key name to the filetree command.
Wrapped lines to keep them under 80 chars.
This reverts commit 29c78ce841 and all other fixes
that have been made afterwards.
The motivation is that use-package is seen by many as a replacement for
`require`. Is use-package always defer the loading of packages then is breaks
this use case, this does not respect POLA so even if it was making Spacemacs
loading faster (up to 3s faster on some startup on my machine) we just cannot
use it, it would be irresponsible. Spacemacs should be easy to use, loading
performance will come with time but it is not a priority.
