8 months ago Not sure what's the problem. require-package installs a package from elpa. require load a package if it can be found from load-path. featurep checks if a package is loaded. You can require a package multiple times. require has some builtin code works same way s featurep.
As an example, I use require-package to install and require 'vterm. And (featurep 'vterm) return nil.
And in another package vterm-toggle, it require vterm. The require function use featurep to define whether vterm is loaded. This lead to double load of vterm and lead emacs to crash finally.
I think the biggest problem is that require-package doesn't act like require when you check the symbol with featurep, which may lead to double load and is hard to detect.
ls there some way to fix it?
