clojurebridge / global-growth Goto Github PK

We need a shell project with everything in it except for the pieces that will be built in the workshop. This will include:

• leiningen project.clj with all dependencies defined
• source file with several supporting functions defined enabling the app to be fully functional and work as a web app.

I named it cheap-life when I had a different idea of what it would do. I'm horrible at naming things. Any ideas? Global Indicators? World Bank Data Analyzer?

The app.md lesson might go more smoothly with a few changes to the shell-project version of global-growth. If the current version is also used for other lessons that would be impacted by these changes, please consider an alternate branch for the proposed app.md version.

*1. Add the following constants and helpers to core.clj:

;; CONSTANTS
(def base-uri "http://api.worldbank.org")
(def list-size 10)

(defn parse-json [str]
  (json/parse-string str true))

*2. Add a line calling out

;; SUPPORTING FUNCTIONS

above the pre-populated supporting functions section.

*3. Include the complete lines for:

(defn view-ind
  [indicator1 indicator2 year]
  (let [inds1 (sorted-indicator-map
                (get-indicator-all indicator1 year :country :value))
        inds2 (sorted-indicator-map
                (get-indicator-all indicator2 year :country :value))]

instead of:

(defn view-ind
  [indicator1 indicator2 year]
  (let [inds1 (<<FILL IN THE BLANK>>)

        inds2 (<<FILL IN THE BLANK>>)]

Trying to get it working, I had to change the project.clj generated by the clojurebridge leiningen template:

                 [cheshire "5.2.0"]
                 [ring "1.2.1"]

                 [org.clojure/tools.reader "0.8.8"]]
  :plugins [[lein-ring "0.8.10"]]
;;   :ring {:handler global-growth.web/handler}
  :main ^:skip-aot global-growth.core
  :target-path "target/%s"
  :repl-options {:nrepl-middleware [lighttable.nrepl.handler/lighttable-ops]})

Specifically, note how I had to exclude tools.reader, add an explicit dependency on a new version and finally add the lighttable middleware to :repl-options.

Without these changes I wasn't able to start a REPL from lighttable.

I'm happy to submit a PR but couldn't find the repo where the leiningen template lives.

I am not sure if this is by design -- like they should be implemented in class -- or not, but only a few of the indicators return any data.

We should start building up the app during the "first program" section of the curriculum. So we build the simplest piece of the app that includes all of the concepts needed in the "first program": a lein project, use a library, namespace, create a function, include a main.
