concat: Symbol’s value as variable is void: whitespace-mode about oremacs HOT 8 CLOSED

This is in keys.el file.

from oremacs.

Calling it after manually calling whitespace-mode does not give error.

Can't reproduce.

I'm not using the config verbatim, so not surprised if it works for you.
If something jumps to your mind as to the reason, I appreciate your sharing.

whitespace-mode is both a symbol and a function defined in whitespace.el.
Possibly, only the function is autoloaded, resulting in the symbol being undefined.
In any case, a simple (require 'whitespace) before defhydra should fix it.

Thanks. I try to follow your way of reducing the use of require. I greped your repo for whitespace-mode. You only define it in keys.el.

I wonder why you don't see this error.

I was actually suggesting to increase it. Your error happens because the whitespace-mode symbol isn't defined.
If you use (require 'whitespace), the symbol will become defined. Just use it before defhydra, not after.

I meant the overall philosophy of this config - autoload/hook stuff to reduce load time.

Thanks for your help. I'm still curious why you don't see this error in your config.
