Adds a fully WYSIWYG equation editor (WIRIS editor) and, optionally, an advanced calculator tool (WIRIS cas) to Atto.

WIRIS editor is a mathematical visual (WYSIWYG) editor. You can use a large collection of icons nicely organized in thematic tabs in order to create formulas or equations for any web content. You can create and edit your formulas in a visual environment, just click on the WIRIS editor icon for creation or double-click on the formula for edition. No maintenance when upgrading Moodle to a new minor version. It is based on JavaScript and compatible with HTML 5.

WIRIS cas is an online platform for mathematical calculations designed for education. You can access a powerful calculation toolbar through an HTML page that includes integrals and limits calculation, function graphing in 2D or 3D and symbolic matrices manipulation, among others. WIRIS cas covers all mathematical topics from primary school to university level (Calculus, Algebra, Geometry, Differential Equations...).

This plugin depends on WIRIS filter which must also be installed.

For Moodle <=2.3 it is available from


This plugin is part of set WIRIS math & science.

    Thanks for sharing this plugin with the community. I was able to test the functionality and reviewed the code and I am going to approve it now. There are two things I noticed during the review.

    1) The toolbar icons do not fit well into the style of default toolbar icons.
    2) The plugin would like to use a cache folder located inside the plugin scope. Note that many sites prefer having the $CFG->dirroot read-only. You could consider switching to a folder inside $CFG->dataroot or even better to try and make use of the Moodle universal cache (MUC) system.

    David, thank for your feedback.

    I'm thinking you are mistaken on the cache stored point: by default WIRIS cache is placed in $CFG->dataroot/cache/filter (you can see it in MoodleConfigurationUpdater.php file in filter plugin) . Users can change that editing 'wiriscachedirectory' and 'wirisformuladirectory' variables in filter configuration filter.

    However it's a good idea using MUC instead a dataroot cache folder. We will consider implementing this feature in future releases. I personally think that it would be a great improvement.
