Wolfram Alpha integration in Emacs

Allows you to query Wolfram Alpha from within Emacs.

Installation

Install package wolfram from MELPA or download wolfram.el to a directory in your load-path. Then add this to your init file:

(require 'wolfram)

Variables

Wolfram Alpha App ID

Create an account at wolframalpha.com, then in your account select "My Apps (API)". Create a new AppID. In Emacs set that AppID as the custom variable wolfram-alpha-app-id.

Optional Dark Mode

Enable dark mode by setting wolfram-use-dark-version to t in your configuration file. Dark mode requires ImageMagick's convert utility to invert images for a dark theme. Without ImageMagick installed, image inversion will not function, and a warning will be displayed if dark mode is enabled.

(setq wolfram-use-dark-version t)

Magnification Factor

Adjust the magnification factor for images in query results using the custom variable wolfram-alpha-magnification-factor. A higher value results in larger images.

(setq wolfram-alpha-magnification-factor 1.5)

Set the factor according to your viewing preferences and display resolution.

Usage

To make a query, run M-x wolfram-alpha then type your query. It will show the result in a buffer called *WolframAlpha*.

Examples

How much does Lake Victoria weigh?

How many nukes does the United State have?
