KaTeX plugin and mhchem

  • hi,

    thank you for the plugin, I really like it. But I’m planning to write chemical equations, so I need mhchem extension.

    I’d like to keep all the scripts locally, so this is what I did: I downloaded mhchem.min.js to katex-0.12.0 folder and changed resource.php file: I registered the script:

    	wp_register_script(
            'mhchem',
            KATEX__PLUGIN_URL . 'assets/katex-' . KATEX_JS_VERSION . '/mhchem.min.js',
            array(), // No dependencies.
            false, // No versioning.
            true // In footer.
        );

    then added the line:
    wp_enqueue_script('mhchem');

    It seems to be working mostly although some formulas aren’t working, e.g. \ce{A\bond{-}B\bond{=}C\bond{#}D}

    Maybe there is some better way to do it? I’m not a wordpress coder.

    Besides, if I decide to use cdn, is there any easy way to change the code to use jsDelivr CDN?

    Thank you.

    Yes, this would be the way to do it.

    To use jsDelivr this works:

    	wp_register_script(
            'mhchem',
            '//cdn.jsdelivr.net/npm/katex@' . KATEX_JS_VERSION . '/dist/contrib/mhchem.min.js',
            array(), // No dependencies.
            false, // No versioning.
            true // In footer.
        );

    I’m not sure why those formulas do not work. Are you using them inside a KaTeX block?
