GPG for datomic

http://semperos.com/post/gpg-and-leiningen/
https://github.com/jamesmartin/datomic-tutorial

lein help gpg

To turn off the password check make sure that you have "use-agent" option explicitly enabled in ~/.gnupg/gpg.conf. See gpg option list.

You can test the config and unlock the gpg key with

gpg --quiet --batch --decrypt ~/.lein/credentials.clj.gpg

Pull example

(def entity-query '[:find [?e ...]
                    :where
                    [?e :question/text ?text]
                    [?e :question/time ?time]
                    [?e :question/source-identifier ?source-identifier]])

(defn pull-questions

      (map #(d/pull db '[*] %)))))

Leiningen + Maven

Currently to make this work I am maintaining a pom.xml and a project.clj for the recording studio package. Sometimes Leiningen overwrites the pom.xml in which case packaging the jar with maven stops working. The indications that this happened are that the recording studio beans module cant resolve the recording_studio namespace.
