Getting the version of the current clojure project in the repl

While you can parse project.clj yourself, this may be annoying. It's also a lot of work. Instead, you can just do:

(System/getProperty "projectname.version")

Leiningen project files are just Clojure data :)

(-> "/path/to/project.clj" slurp read-string (nth 2))

I use environ (https://github.com/weavejester/environ) which sucks in settings from a number of sources, including system properties. The project version appears as :<project-name>-version:

foobar.repl=> (require '[environ.core :refer [env]])
nil
foobar.repl=> (:foobar-version env)
"0.1.0-SNAPSHOT"
