Emacs setq before loading

Question

When setting up Emacs, do I set the appropriate variable before downloading the package or after?

i.e.,

(setq some-variable some-value)
(require 'some-package)

or

(require 'some-package)
(setq some-variable some-value)

It seems to me that most of the time they work, unless some packages explicitly require init after loading. I'm right?

Answer 1

If the variable is a custom option, do this before downloading the package. The package contains defcustom, which defines the parameter, but defcustomwill not set the value if the variable already has a value (for example, from yours setq).
