Why PrismJS? --------------------------------------------------- One of the editors in Moodle is TinyMCE, and the Code Sample plugin makes use of PrismJS. Hence, the code-highlighter filter likewise uses PrismJS to get the same behavior and look. As a result, when we need to upgrade the PrismJS version in this filter, We must take into account the PrismJS version that TinyMCE is currently using. Upgrading steps: --------------------------------------------------- Prerequisite: Make sure the grunt watcher is running during the below process: 1. In yourmoodle directory, run "npm install && grunt watch -f". It will generate minified js files automatically if there is a change in all JS files in the amd folder. 2. Download PrismJS See the lib/editor/tiny/thirdpartylibs.xml to get the current TinyMCE version (X.Y.Z). Download the ZIP file at https://github.com/tinymce/tinymce/tree/X.Y.Z and extract the ZIP file. For instance, if TinyMCE version is 6.3.2, the file to download should be https://github.com/tinymce/tinymce/tree/6.3.2. 3. In the extracted folder, run "yarn". 4. Update the PrismJS version in filter/codehighlighter/thirdpartylibs.xml according to the PrismJS version in the extracted folder in the file node_modules/prismjs/package.json. 5. Copy the node_modules/prismjs/themes/prism.css to yourmoodle/filter/codehighlighter/styles.css 6. Edit the styles.css to make sure the indentation is made using spaces, not tabs, and remove trailing spaces. 7. To avoid conflict with the theme code tag style. Remove all the lines that contain 'code[class*="language-"]' text in the styles.css, and also remove the comma character after the text if necessary to make sure that the CSS structure is correct. Please see the examples below: * code[class*="language-"], * :not(pre) > code[class*="language-"], * code[class*="language-"]::-moz-selection, * code[class*="language-"] ::-moz-selection * code[class*="language-"]::selection, * code[class*="language-"] ::selection * code[class*="language-"] 8. See if the grunt watch is reporting problems. If yes, follow the instructions to fix it. e.g: Before: ``` pre[class*="language-"]::-moz-selection, pre[class*="language-"] ::-moz-selection { pre[class*="language-"]::selection, pre[class*="language-"] ::selection { ``` After: ``` pre[class*="language-"]::-moz-selection, pre[class*="language-"] ::-moz-selection { pre[class*="language-"]::selection, pre[class*="language-"] ::selection { ``` And remove the warning from color-hex-case by renaming "#DD4A68" to lowercase "#dd4a68". 9. In the extracted folder, run "./bin/build-prism.js" 10. Copy the node_modules/prismjs/prism.js to yourmoodle/filter/codehighlighter/amd/src/prism.js 11. Edit the prism.js to make sure the indentation is made using spaces, not tabs, and remove trailing spaces. Note: As long as the grunt watcher says Done, then the upgrade process is complete. classes/privacy/provider.php000064400000002450152266604540012234 0ustar00. namespace filter_codehighlighter\privacy; /** * Privacy Subsystem for filter_codehighlighter implementing null_provider. * * @package filter_codehighlighter * @copyright 2023 Meirza * @license http://www.gnu.org/copyleft/gpl.html GNU GPL v3 or later */ class provider implements \core_privacy\local\metadata\null_provider { /** * Get the language string identifier with the component's language * file to explain why this plugin stores no data. * * @return string */ public static function get_reason(): string { return 'privacy:metadata'; } } classes/text_filter.php000064400000003026152266604540011256 0ustar00. namespace filter_codehighlighter; /** * Code highlighter filter. * * Filter converting text code into a well-styled block of code. * * @package filter_codehighlighter * @copyright 2023 Meirza * @license http://www.gnu.org/copyleft/gpl.html GNU GPL v3 or later */ class text_filter extends \core_filters\text_filter { #[\Override] public function filter($text, array $options = []): string { global $PAGE; if (!isset($options['originalformat'])) { return $text; } // The pattern. $re = '//i'; // Stops looking after the first match. preg_match($re, $text, $matches); if ($matches) { $PAGE->requires->js_call_amd('filter_codehighlighter/prism-init'); } return $text; } } amd/src/prism.js000064400000356255152266604540007616 0ustar00const prismjs = function(global, module, exports) { // preserve the global if it has already been loaded const oldprism = window.Prism; window.Prism = { manual: true }; /// var _self = (typeof window !== 'undefined') ? window // if in browser : ( (typeof WorkerGlobalScope !== 'undefined' && self instanceof WorkerGlobalScope) ? self // if in worker : {} // if in node js ); /** * Prism: Lightweight, robust, elegant syntax highlighting * * @license MIT * @author Lea Verou * @namespace * @public */ var Prism = (function (_self) { // Private helper vars var lang = /(?:^|\s)lang(?:uage)?-([\w-]+)(?=\s|$)/i; var uniqueId = 0; // The grammar object for plaintext var plainTextGrammar = {}; var _ = { /** * By default, Prism will attempt to highlight all code elements (by calling {@link Prism.highlightAll}) on the * current page after the page finished loading.
