Description

Explore the vast world of computational knowledge available for free via Wolfram's v2 API.

Install

To install this gem:

gem install wolfram

Setup

You'll need a Wolfram Appid (api key) by creating an account here and then clicking on the 'Get an APPID' button.

Once you have your own appid, set it in your shell, preferably in your ~/.bashrc:

export WOLFRAM_APPID='YOURKEY'

If you want to explicitly set your appid in a script:

Wolfram.appid = "YOURKEY"

Usage

Query away on the commandline!

# Calculate distance and travel time between places
wolfram from boston to new york

# Solve an equation
wolfram x^3 - 4x^2 + 6x - 24 = 0

# Find words ending with able
wolfram words ending with able

Regular ruby usage:

query = 'boston population'
result = Wolfram.fetch(query)
# to see the result as a hash of pods and assumptions:
hash = Wolfram::HashPresenter.new(result).to_hash

For many more examples, see here.
