envclj

(env name)
(env name type & options)

Resolve an environment variable by name. Optionally accepts a type for coercion, and a keyword option, :or, that provides a default value if the environment variable is missing.

The arguments may optionally be wrapped in a vector. This is to support their use in [[duct.core/read-config]]. For example:

{:port #duct/env ["PORT" Int :or 3000]}
