imcljs

A Clojure/ClojureScript library for interacting with InterMine's web services.

Getting Started

Add the necessary dependency to your project:

imcljs returns channels so you'll also want to include core.async

[org.clojure/core.async "0.2.395"]

Usage

With the exception of the fetch/registry function, all imcljs functions expect a map as their first parameter containing a mandatory :root key and two semi-optional keys, :token and :model.

(def flymine {:root  "https://www.flymine.org/flymine"
              :token nil ; Optional parameter for authentication
              :model "genomic" ; Required by some functions, such as executing a query
              })

We recommend fetching the model once and storing it in the above map for re-use across your application.

Examples

Fetching a list of InterMines from the Registry

(let [;fetch all mines except the dev/beta mines
      prod-mines (fetch/registry false)
      ;fetch all mines INCLUDING the dev/beta mines
      dev-and-prod-mines (fetch/registry true)]

      (go
        (let [prod (<! prod-mines )
              dev (<! dev-and-prod-mines)]
          ;; This should print true, so long as the sum of dev+prod mines is 
          ;; greater than the count of prod mines
          (.log js/console (< (count (:instances (:body prod)))
              (count (:instances (:body dev)))))
          )))

Fetching assets

; Fetch model (you'll need this for later.)
(go (log (<! (fetch/model flymine)))

; Fetch templates
(go (log (<! (fetch/templates flymine)))

; Fetch lists
(go (log (<! (fetch/lists flymine)))

; Fetch summary fields
(go (log (<! (fetch/summary-fields flymine)))

Fetching query results

Most result-fetching functions require that the :model key be present in their first parameter.

(ns my-app.core
  (:require-macros [cljs.core.async.macros :refer [go]])
  (:require [imcljs.fetch :as fetch]
            [cljs.core.async :refer [<!]]))


(def my-query {:from   "Gene"
              :select ["Gene.secondaryIdentifier Gene.symbol"]
              :where  [{:path  "Gene.symbol"
                        :op    "="
                        :value "a*"}]})

; Rows
(go (log (<! (fetch/rows flymine my-query))))

; Records
(go (log (<! (fetch/records flymine my-query {:size 10}))))

; Row Count
(go (log (<! (fetch/row-count flymine my-query))))

Development

Running tests

Required dependency: phantomjs, to run the tests in a headless javascript engine. You'll need a recent version of node installed, perhaps via nvm. Once node is installed, run npm install -g phantomjs to install phantomjs.

Local biotestmine: The tests are run against a local biotestmine instance on port 9999 (can be changed in test/cljs/imcljs/env.cljs). If you're not familiar with building InterMine instances, we recommend using intermine_boot.

To run tests in the browser:

lein doo

To run tests in the JVM:

lein test

Releasing new versions (Clojars)

1. Update the version number in project.clj
2. Don't forget to add the new version with notes to CHANGELOG.md.
3. Tag the release with a matching version number in git and push the tag to GitHub
4. To push the release to Clojars, type lein deploy clojars. Note that you'll need to have a clojars account that is a member of the org.intermine team. Currently (October 2018) this is @yochannah, @sergio, @danielabutano and @julie-sullivan.

API Docs

API docs for IMCLJS are available at intermine.org/imcljs.

These docs are automatically generated by Travis when anything is merged to master.

If you would like to generate them locally, run lein codox and go to your target/docs folder.

Formatting

Builds will fail unless your file is formatted correctly. Write code with whatever formatting you like - but before you commit and push, run lein format to auto-format your file to the required standards. The formatting is managed using the cljfmt package.
