:use vs :require

[ChipNowacek]

Any comment on :use vs :require? I keep seeing recommendations to abandon :use. I'm not clever enough to know exactly why.

Not that this is from the god of Clojure: https://github.com/bbatsov/clojure-style-guide/blob/master/README.md#prefer-require-over-use

Just a point of reference.

":use" is apparently deprecated in favour of ":refer :all". I prefer ":use" because it's shorter and it's a straight syntactic shift when and if :use is removed. The main that people dislike :refer :all is that it raises the possibility of name clashes, out of the control of the authors. So, for example, in some namespace I might do [tawny.owl :refer :all] and find everything is happy. Then "clojure.core" might get updated and introduce a function "only". Now my code is broken. All valid concerns. But tawny is not a normal library -- it's more of an application. I have entire namespaces with *no* clojure.core functions in them at all. Having to type "(o/defclass blah)" to avoid a minor problem in the future, which can be worked around using ":refer-clojure :exclude [only]" seems silly. Or, as bbatsov says "Acceptable as Warrented". Phil ChipNowacek <[email protected]> writes:
