How to call a function read from an EDN file?

[Christopher Lee]

Clojure noob here.

After reading in the google-creds.edn file like so:

"(edn/read-string (slurp "config/google-creds.edn"))"

How do I call the function get-auth-map on this EDN file, along with the OAuth scope (["https://www.googleapis.com/auth/calendar"]) ?

Hey Christopher,

Welcome to the wonderful world of Clojure and we're glad to have you!

It appears you are trying to authenticate using Google's OAuth library and are currently using the google-apps-clj wrapper.

You have to either keep a reference to the return value of reading in the config file that you can pass as the first argument to the function google-apps-clj.credentials/get-auth-map or just pass (edn/read-string (slurp "config/google-creds.edn")) as the first argument directly. 

While I haven't used the library myself, here's how I would do steps 8, 9 and 10 in the REPL -

(let [config "config/google-creds.edn"

      creds (edn/read-string (slurp config))

      scopes ["https://www.googleapis.com/auth/calendar"]

      auth-map (google-apps-clj.credentials/get-auth-map creds scopes)

      updated-creds (assoc creds :auth-map auth-map)]

  (spit config (pr-str updated-creds))

  updated-creds)

I haven't tried this so forgive any typos, but it should give you the general idea.

I hope this helps and feel free to post any follow up questions you may have.

Best,

Simon
