While adding Tiny_wiris i found a problem with the Behat automated tests from lib/editor/tiny/plugins/wiris/tests/behat
Specially in the step
And I press "Toggle" in "FIELDNAME" field in TinyMCE 6 editor

For example in edit_formula.feature, see:

Scenario: Create a formulas                                               # /builds/moodle/lib/editor/tiny/plugins/wiris/tests/behat/edit_formula.feature:17
And I press "Toggle" in "General description" field in TinyMCE 6 editor  # /builds/moodle/lib/editor/tiny/plugins/wiris/tests/behat/edit_formula.feature:24
"Toggle" button not found in "General description" field

This caused by a string change here in filter_wiris, see fix: Test for Moodle 4.4 compatibility
The string changed from "More..." to "Reveal or hide additional toolbar items", but i don't see it added in any language File, so the Toggle button it's actually showing "More..." text.

So changing "Reveal or hide additional toolbar items" back to "More..." fix the issue, here in behat_wiris_page.php
"Toggle" => "More..."

Can you fix those Behat steps? Thanks in advice

Can't move equation from Wiris popup to Moodle editor.
When viewing previously saved equations, the filter is not processing inside the editor.

La versió nova del filtre de wiris té el warning següent (perquè fa referència a una variable que no està declarada enlloc):

Notice: Undefined variable: carry in /dades/agora/html/moodle2/filter/wiris/lib.php on line 125

Hello,

Wiris filters the input by checking for unicode char « in the string. stripos is used, which is non-multibyte. Which doesn't matter on many Linux systems. stripos makes lower case chars out of the haystack, but just ignores the Multibyte chars (doesn't change them, not even to lower case versions).

But on Solaris, rather on PHP 7.1.x (PHP 5.6.x worked), when you have a string like this: "uPPerCase«math[...]", Solaris changes to lowercase and can't find the needle anymore.

Easy solution: Just search for multibyte needles using mb_stripos.

Pull request follows.

The new css file causes most text to be bold and all tables to have borders. Easily noticeable on the calendar block. The css should have more specific selectors.

The current style to change some of the configuration of this plugin is to store it in the file https://github.com/wiris/moodle-filter_wiris/blob/stable/configuration.ini.dist (without the .dist suffix).

This is kind of the only Moodle plugin I know of that stores configuration data in the code folder. Could you please move that part of the configuration to either entries in the Moodle config_plugins table or to a Wiris folder inside moodledata?

Leaving the configuration in the code folder may lead to problems and additional steps during deployment of new plugin versions or to possibly ignoring the configuration because of the unusual storing point.

EDIT: The storing point is maybe something used for each and every Wiris plugin. If that is the case, changing the path for Wiris for Moodle only would of course not be feasible. But you could abstract away from the concrete configuration file, its path and how to read it, and then you could have a "general way" (as a file, in the plugin folder) and a Moodle plugin way (in the db or in moodledata as a file)

During a Moodle quiz, we experienced the follow message. Is this an issue with how the filter works, or is it a server configuration issue?

Hi,

Problem
After upgrading the PHP on our server to version 8.1.16, the "Site administration" main page is unreachable, and also the at least the "Plugins overview" page. Instead of the page itself, we see the following message:

"PATH", of course, is not the original text. We "blurred" the actual path in this bug report.

This bug is a serious issue that prevents us not only from using the plugin, but also impacts the general use of the system. Please fix this bug as soon as possible.

Moodle 4.1 supports PHP 8.1 officially, to the best of our knowledge, so if the plugin supports Moodle 4.1 officially, and it does, it should also be able to work correctly in a PHP 8.1 environment.

Thanks

Moodle: 3.9
Wiris: 7.26.0 2021050600

We have updated to Moodle 3.9 and Wiris 7.26.0 and have discovered that the TinyMCE editor no longer loads. We've discovered that Moodle is trying to fetch the file /filter/wiris/integration/configurationjs.php (with an explicit /filter/wiris/... path) which doesn't work on our instance as our Moodle is in a sub-directory.

The browser loads these files and other TinyMCE files fine,
/moodle3/lib/editor/tinymce/tiny_mce/3.5.11/tiny_mce.js
/moodle3/lib/editor/tinymce/tiny_mce/3.5.11/plugins/visualchars/editor_plugin.js

If I deliberately copy configurationjs.php onto the webserver into a directory were it is accessible as /filter/wiris/integration/configurationjs.php then the TinyMCE editor loads correctly.

I think Wiris' TinyMCE plugin contains an explicit path to /filter/wiris instead of filter/wiris

Hi,

We have a moddle installation with the WIRIS plugin integrated. When we are resolving a quizz, the WIRIS editor is working properly in the quizz editor, but when we try to save the response (processattempt) we're getting the following error:

Unknown driver native/mysql

Needless to say that this is a moodle already in production and that all other plugins are working and therefore getting the database driver / properties properly, so in this case this is the only plugin showing up this error. All the responses I could find to this scenario talks about a global issue vs a particular one.

Sorry for not providing more details, I'm not the administrator of the platform but trying to find a lead to help them figure out the issue so we can use this amazing plugin. Is there anything that you think may be affecting the DBconfig only for the WIRIS plugin?

Thank you!

We are having an issue when using English US as the default language for Moodle. It breaks the buttons in the atto editor. We get a 404 error in the browser for the language string. Editor/atto/plugins/wiris/lang/en_us is missing. I copied the en folder and made it en_us and the editor started working again.

hi,
in integration/lib, a lot of files aren't in UTF8, and have strange characters.
Exemple in integration/lib/Hash.class.php:
line 14:

$»it = $it;
while($»it->hasNext()) {

line 57: else if(isset($this->»dynamics[$m]) && is_callable($this->»dynamics[$m]))

Is it correct ?

I've noticed that the "not equal to" symbol is displaying as a hyphen, but only in IE edge. See the PHP integration demo here for example: http://www.wiris.com/plugins/demo/tinymce4/php/.

To reproduce, in IE edge click the "Insert special characters" button, then search for "8800" or select the "not equal to" characer. It shows correctly in the editor, however, once you click "Ok" the symbol shows up as a hyphen (see below):

This happens with any of the integration demos and only in IE edge. I'm assuming it has to do with this specific package, but I could be wrong.

Any idea what is causing this?

Manage MathType Web Integration configuration data dinamically using Moodle's Admin settings UI

We want to allow users to manage the MathType Web Integration configuration settings data dinamically using Moodle's Admin settings UI and store them using a Moodle's complaing solution.

We've defined these next user stories:

01: Manage settings dinamically

As a Moodle Administrator,
I want to manage the configuration settings from the MathType Web Integration library,
that is a third-party dependency of the plugin,
using the regular Moodle's Admin UI,
so I don't need to manage them using a static file on the plugin's root folder.

02: Upgrading the plugin

As a Moodle Administrator
when upgrading to the latest version of this plugin,
of an instance using the filter/wiris/configuration.ini file method,
I want an automatic upgrade path to keep things consistent, and
be informed of any important information.

Issue definition

This plugin stores some of its configuration's settings data in the plugin's root folder, using a static file named configuration.ini.dist.

The configuration.ini.dist is part of the "MathType Web Integration PHP" library filter that allows Moodle to access the render services provided by the Wiris API.

For more details, visit MathType Configuration table docs page and thirdpartylibs.xml.

Analysis

Using a static file to store configuration's settings data is bad since:

• It may lead to problems and additional steps during deployment of new plugin versions or to possibly ignoring the configuration because of the unusual storing point.
• The configuration file can be potentially be removed when upgrading this plugin's code on the Moodle instance.
• It's not a Moodle plugin development good practice.

Motivation

The reasons to keep this file on the Moodle's root folder are:

• Compatibility with other PHP platforms where the MathType Web Integrations PHP library is used.
• Software maintanability: the same strategy is used for other back-end platforms like .Net, Java or Rails.
• Historical reasons: this library is being used for more than a decade now, so any solution we may come with should aim for complete backward compatibility.
• Therefore, It would require a new feature request to specify which problem needs to be solved and a proposed solution.

Feature request specification

We want to expose this configuration settings using Moodle's Admin settings UI and store them on a more Moodle's native way like config_plugins tables or the Moodledata directory.

In other words, the plugin's configuration settings data should be stored dinamically.

The plugin will expose "MathType Web Integration PHP" library configuration settings using Moodle's Admin settings UI, instead of the configuration.ini.dist configuration file.

Admin users will be able to manage the MathType Web Integration Library Server configuration file (configuration.ini) settings using Moodle's UI.

The configuration settings data will be stored using Moodle plugins development best practices. Like config_plugins tables, the Moodledata directory.

At the same time, we want to offer backward compatibility with Moodle installations using the current configuration.ini.dist method.

Therefore, the solution proposed must also include an upgrade path when updating to this version of the plugin.

So it would need to be decided what to do if the /configuration.ini.dist file already exists on a Moodle's instance.

Other details

• The original motivation of this feature request is @danowar2k 's reported issue: #79.

When testing the upgrade to Moodle 4.2 I run into a serious issue with the Wiris Filter plugin :

uncaught exception: require_once(/var/www/html/lib/editor/tinymce/lib.php): Failed to open stream: No such file or directory (errno: 2) in /var/www/html/filter/wiris/classes/pluginwrapper.php at line #160require_once(/var/www/html/lib/editor/tinymce/lib.php): Failed to open stream: No such file or directory

This makes the Admin panel inusable.

I guess it might have something to do with the legacy MCE editor which was removed in Moodle 4.2. lib/editor/tinymce is no longer present in 4.2, only lib/editor/tiny.

Moodle will begin to recommend utf8mb4 in upcoming versions. https://tracker.moodle.org/browse/MDL-54901

I've recently attempted to install WIRIS on a new 3.3 running with utf8mb4 collation. It will not install because of the md5 unique key being too many bytes. Keys have a maximum of 191 characters, or 764 bytes.

This just started happening and was passing before with the exact same code. I think it's reaching out to talk to an external service?

   Failed asserting that false is true.

To re-run:
vendor/bin/phpunit "filter_wiris_filter_performance_svg_testcase" filter/wiris/tests/filter_performance_svg_test.php

I am getting a lot of console messages like:
"Deprecated property configurationService. Use serviceParameters on instead."
Is that OK?

All seems to work fine, weird.

Hi,

i got an error during updating Wiris Version 2017040600 (4.2.0.1364) to 2019071200 (7.15.0) with Moodle Version: 3.2.7 (Build: 20180115)

Error:
Debug info: Index filter_wiris_formulas->md5 does not exist. Drop skipped Error code: ddlunknownerror Stack trace: • line 857 of /lib/ddl/database_manager.php: ddl_exception thrown • line 96 of /filter/wiris/db/upgrade.php: call to database_manager->drop_index() • line 558 of /lib/upgradelib.php: call to xmldb_filter_wiris_upgrade() • line 1748 of /lib/upgradelib.php: call to upgrade_plugins() • line 693 of /admin/index.php: call to upgrade_noncore()

Commenting out line 96 from upgrade.php
--> //$dbman->drop_index($table, $index);
fixes the error for me.

Hello:

We have saved equations in MathML format. It works fine for HTML viewing but when to try to save in PDF nothing is getting displayed.

What can be the issue?

Hi,

This error occured when I tried to start a quiz or when I tried to update plugins:

uncaught exception: Call to undefined function uuid_make()in file: /home/maicolml/public_html/quiz/lib/setuplib.php line 618

Now I have commented these lines of the setuplib.php file and it works:

if (function_exists("uuid_create")) { $context = null; uuid_create($context);  uuid_make($context, UUID_MAKE_V4); uuid_export($context, UUID_FMT_STR, $uuid); } else { 

Please delete them otherwise users that will install WIRIS plugin will affect this issue...

Steps to test this:

• Install WIRIS plugin
• Make a quiz with WIRIS plugin
• Try to start the quiz or update a plugin

Hello,

If I have filter_wiris 7.12.0.1412 (2019040800) enabled on a course on Moodle 3.5.5 I cannot add any files to f.ex. assignment additional files field or Course summary files with Internet Explorer 11, it just loads forever.

So the wiris filter disables filepicker in certain fields with IE11. Seems like a pretty bad bug. @manuelwiris

With another browser like Chrome filepicker works wiris filter enabled on a course.

In PHP 7.4, the ability to pass the glue string after the array has been deprecated for the implode function and its join alias.

In the filter/wiris/integration/lib/php/Boot.class.php file, there are two occurrences of the join functions on lines 834 and 840 are two occurrences of this function with the incorrect parameter order which results in the script crashing.

I have not checked other files for use of the join function.

When testing on a machine with PHP 7.4.3 I receive the message:

Array and string offset access syntax with curly braces is deprecated in /data/mdl38/www/filter/wiris/integration/lib/php/Boot.class.php on line 221

I am getting the following error on a quiz page that uses WIRIS with ATTO

Hello. Using Moodle 3.9 and Wiris Filter 7.24. Until yesterday, everything was fine. No change was maded and today equation editor is not loading. In console I've noticed that:

15:24:05.530 GEThttps://www.wiris.net//demo/editor/editor?lang=en&stats-editor=unknown&stats-mode=safeXml&stats-version=7.23.0
[HTTP/2 403 Forbidden 716ms]

There is double slash after domain name. But in settings all is correct:
Service path is set to /demo/editor/render

I've tried to remove first slash in setting but that do not solve the issue.

Thank you.

Hi,
since 4.9.0.1380 (or maybe before), in Atto editor, french quotation marks (« ») replaced by < >when we save, or just when we switch view with the HTML button.
We have updated plugin to 4.11.0.1383, and problem is still present.
When we remove wiris button (row "math = wiris" in "editor_atto | toolbar" parameter), we don't have problem anymore.

Hi,
We have a bug in a upload filepicker when atto_collapse showgroups is set to display MathType and ChemType button.

To reproduce our error:

• Go to Plugins -> Text editors -> Atto HTML Editor -> Collapse toolbar settings and set showgroups to 11 or 12.
• Go to an existing forum post, and reply (for example). And the upload filepicker shows the following error:

If you set showgroups to less than 11, the bug does not appear.

Versions:

• Moodle: 3.9.1
• Wiris atto editor: 2020090300

I have a simple equation in a course label. Sometimes I get the following error and sometimes it works as expected.

uncaught exception: fopen(/var/www/moodledata/SharedCache/cachestore_file/default_application/core_databasemeta/bbf-cache/bbf213178611dfbe0e377620f6d0b86824991516.cache): failed to open stream: No such file or directory (errno: 2) in /var/www/moodle/cache/stores/file/lib.php at line #358fopen(/var/www/moodledata/SharedCache/cachestore_file/default_application/core_databasemeta/bbf-cache/bbf213178611dfbe0e377620f6d0b86824991516.cache): failed to open stream: No such file or directory

It seems I am getting weird and maybe redundant web requests to filter/wiris/integration/configurationjs.php as I open a question for editing.

What do you think?

Wiris helps in storing MathML to the database by converting MathML to SafeXML so that Moodle's HMTLPurifier doesn't clean the math tags before storing to database.

Wiris then also converts the SafeXML to regular MathML (at least I presume it does) before requesting an image from the Wiris servers for the converted formula.

To be able to use Moodle's MathJax filter instead for displaying the MathML formula, it would be nice to have the option to disable replacing the MathML with the image HTML.

If disabled, the filter would just output the MathML so that other filters can postprocess it.

Would that be possible?

Looking at the browser console, while the WIRIS editor is activated (works just fine), I see requests to "http://www.wiris.net/demo/editor/..." , Is that OK? as I have a paid version of WIRIS.
