Question: How does spacemacs|spacebind modify behaviour of use-package

[lebensterben]

It says that

spacemacs/core/core-spacebind.el

Line 417 in b71e5fd

NOTE: This macro also has `use-package' integration via `:spacebind' key

And AFAIK the only way to 'hijack' an external function's behaviour is through advice, but use-package is not advised.

I'm curious on how :spacebind keyword is added to it.

@lebensterben It can be used inside use-package form. Tests have a case for it:

spacemacs/tests/layers/+distribution/spacemacs-base/spacebind-utest.el

Lines 59 to 69 in 7ef15a5

	(ert-deftest test-spacebind-use-package-integration-works ()
	(thread-last (use-package use-package
	:spacebind
	(:major
	(python-mode
	"with a description"
	("c" "compile/execute"
	("c" spacemacs/python-execute-file "execute file")))))
	(test-spacebind|process-bind-stack-called-p)
	(eq t)
	(should)))
