Importing syntax

Stateful functions for use in the ohua macro are being brought into scope with a macro called com.ohua.lang/ohua-require. The ohua-require macro scans the classpath for the specified functions, loads them and makes them available for use with ohua in the namespace in which it was called. It supports qualified and unqualified imports as well as aliasing for both namespaces/packages and functions.

Important

Importing stateful functions like this makes them available only for use in the ohua macro. They will not be available via the standard clojure symbol resolution. If you must resolve the functions yourself use com.ohua.link/resolve.

The syntax for ohua-require is intentionally similar to clojure.core/require.

(ohua-require
    [my.package]
    [my.package :as package]
    [my.package :refer [function]]
    [my.package :refer :all])

The macro takes a lists or vectors as input. The first element of each is the name of a package/namespace which should be imported. Functions from the package are then available qualified as my.package/function. Optionally you may alias the package using the :as keyword and providing a new name to bind the package to. And lastly you may use :refer to specify functions which should be imported such that they may be used unqualified. :refer :all makes all functions from the package available as unqualified imports. These are the only require semantics which are currently implemented.
