WIRIS math tools enhances your Moodle with WIRIS editor and WIRIS cas.

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...).

You also need to install WIRIS plugin for TinyMCE or  WIRIS plugin for Atto .

The same components for Moodle 1.9 can be found here.

WIRIS editor and WIRIS cas can be used for free up to a certain level per natural year. Please read conditions and prices in WIRIS store.

Hi, I'm upgrading from WIRIS filter 2015032700 to 2015041000, and it's stalled the whole database upgrade (failed dependencies check). It says that it requires Atto WIRIS plugin 2015040900, I have 2015041000 already installed and can't see how to upgrade it. There doesn't appear to be an update available when I check. Help?

Ah! Thanks very much

Any chance of having a github repository with the code? It would make our packaging / deployment process for updated versions easier.

Ok, I have a possible major issue I've found with the wiris filter in Moodle 2.9 I was uninstalling the filter and the text editor plugins when suddenly my screen froze. After some searching, it seems that my entire moodledata folder got erased. In the log I see this...

We just upload a new version (3.54.1.1161) fixing the bug you found.

There are a series of php warning while running phpunit tests with the wiris filter installed.

PHP Notice: Undefined property: stdClass::$version in filter/wiris/version.php on line 35 PHP Notice: Undefined property: stdClass::$version in filter/wiris/version.php on line 56

Not a big deal, but it would be nice if this was fixed.

@Matt

We added the issue into our tracker. We'll let you know when the issue is fixed (probably in the next release).

Best,

This page should refer clearly that WIRIS is not open source and it is a commercial solution with costs to non schools or shcools with more than 1000 equations. Many moodlers are using this tool without a clue about this. Please update the plugin description.

Dear António,

The Plugin description does already include the following sentence with a link to WIRIS store

• Sat, Sep 19, 2015, 4:50 AM
Thanks Ramon. However I think it should be stated on the top sentence. I didn't notice it. It is very frustating to install a plugin, inform your users and then have to remove it when you find it is not free like majority of Moodle plugins. Transparency above all. I am sure that the 58k downloads are not shools with less than 1000 Equations and were induced in error like me. 58k * 400 Euros = 23 million Euros annually. This should be taken serious.
