Can't access environment variables in leiningen project.clj with environ
clojure, environment-variables, leiningen
Solution
OK, it was a case of reading the docs more thoroughly. :) To access environment variables specified in the project map you need the lein-environ plugin. Add it like this:
:plugins [[lein-environ "0.4.0"]]
That worked. It's easy to miss that in the docs though.
Problem
I am trying to use environ to access environment variables specified in my project.clj :dev profile. This looks like a nice way to set up different configuration options, but I can't seem to get it to work. My project.clj entry looks like this: ``` :profiles {:dev {:dependencies [[javax.servlet/servlet-api "2.5"] [ring-mock "0.1.5"]] :env {:foo "FOO" :bar "BAR"}}} ``` If I run `lein repl` and require then enter (with `in-ns`) a namespace from my project, `environ.core/env` just returns nil: ``` (environ.core/env :foo) nil ``` Adding an :env entry to the :user profile in .lein/profiles.clj also doesn't work. What am I doing wrong?
