v0.8.0

General improvements

• new joker.os/exit function
• support Clojure 1.9 namespaced destructuring (#6)
• many new functions in joker.string namespace. It is now roughly equivalent to clojure.string

Linter improvements

• warning on duplicate require
• linter now tries to find .joker file in the directory of the file it's linting, as well as all parent directories up to the root. Falls back to ~/.joker. See #7.

Fixes

• fix require of standard namespaces
