\ ce command not recognized within the H5P, no chemical formulas possible

Hi Oliver, 

Thank you for your help.

I tryed your suggestion but  anywhere I paste the command lines an error (syntax error, unexpected T_constant_encapsed_string, expecting ')')

Here is the code:

// BEGGIN ADDED BY ME FROM https://h5p.org/mathematical-expressions $CFG->mod_hvp_library_config = array( "H5P.MathDisplay" => array( "observers" => array( array("name" => "mutationObserver", "params" => array("cooldown" => 500)), array("name" => "domChangedListener"), array("name" => "interval", "params" => array("time" => 1000)) ), "renderer" => array( "mathjax" => array( "src" => "https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/MathJax.js", "config" => array( "extensions" => array("tex2jax.js"), "jax" => array("input/TeX", "output/HTML-CSS"), "tex2jax" => array( // Important, otherwise MathJax will be rendered inside CKEditor "ignoreClass" => "ckeditor" ), "messageStyle" => "none" "TeX" => array( "extensions" => array("mhchem.js") ), ) ) ) ) ); // END - added from https://h5p.org/mathematical-expressions

am I pasting in the right place?

By the way, in my moodle page, to mhchem work on Moodle in filters, I configurated mathjax with the following code ( I don't know if it is relevant to write chemical equations in H5P)

MathJax.Ajax.config.path["mhchem"] = "https://cdnjs.cloudflare.com/ajax/libs/mathjax-mhchem/3.3.2"; MathJax.Hub.Config({ tex2jax: { inlineMath: [['$','$'], ['\\(','\\)']], processEscapes: true }, TeX: { Macros: { sen: "{\\operatorname{sen}}", senh: "{\\operatorname{senh}}", arcsen: "{\\operatorname{arcsen}}", arcsenh: "{\\operatorname{arcsenh}}", arccos: "{\\operatorname{arccos}}", arccosh: "{\\operatorname{arccosh}}", arctg: "{\\operatorname{arctg}}", arctgh: "{\\operatorname{arctgh}}", cossec: "{\\operatorname{cossec}}", cossech: "{\\operatorname{cossech}}", sech: "{\\operatorname{sech}}", tg: "{\\operatorname{tg}}", tgh: "{\\operatorname{tgh}}", cotg: "{\\operatorname{cotg}}", cotgh: "{\\operatorname{cotgh}}", arcsec: "{\\operatorname{arcsec}}", dist: "{\\operatorname{dist}}", mdc: "{\\operatorname{mdc}}", mmc: "{\\operatorname{mmc}}", C: "{\\mathbb{C}}", R: "{\\mathbb{R}}", Q: "{\\mathbb{Q}}", Z: "{\\mathbb{Z}}", N: "{\\mathbb{N}}" }, extensions: ["[mhchem]/mhchem.js"] }, config: ["Accessible.js", "Safe.js"], errorSettings: { message: ["!"] }, skipStartupTypeset: true, messageStyle: "none" }); MathJax.Hub.Register.StartupHook("TeX Jax Ready",function () { MathJax.Hub.Insert(MathJax.InputJax.TeX.Definitions.macros,{ cancel: ["Extension","cancel"], bcancel: ["Extension","cancel"], xcancel: ["Extension","cancel"], cancelto: ["Extension","cancel"] }); });
