Creating mobile question types

An empty template for creating quiz question types with mobile support is available from here

https://github.com/marcusgreen/moodle-qtype_TEMPLATE

The files that need to be modified/added are

db/mobile.php

defined('MOODLE_INTERNAL') || die();

$addons = [

   "qtype_YOURQTYPENAME" => [
       "handlers" => [ // Different places where the add-on will display content.
           'YOURQTYPENAME' => [ // Handler unique name (can be anything).
               'displaydata' => [
                   'title' => 'YOURQTYPENAME question',
                   'icon' => '/question/type/YOURQTYPENAME/pix/icon.gif',
                   'class' => ,
               ],
               'delegate' => 'CoreQuestionDelegate', // Delegate (where to display the link to the add-on).
               'method' => 'mobile_get_YOURQTYPENAME',
               'offlinefunctions' => [
                   'mobile_get_YOURQTYPENAME' => [],// function in classes/output/mobile.php
               ], // Function needs caching for offline.
               'styles' => [
                   'url' => '/question/type/YOURQTYPENAME/mobile/styles_app.css',
                   'version' => '1.00'
               ]
           ]
       ],
       'lang' => [
                   ['pluginname', 'qtype_YOURQTYPENAME'], // matching value in  lang/en/qtype_YOURQTYPENAME
       ],
   ]

];

html template

Your question type will need an html/ionic markup template file that controls how it is displayed at runtime. This is the template from the core shortanswer question type and gives an idea of some of the options. You can see a real world examples of this file at https://github.com/Beedell/moodle-qtype_oumultiresponse/blob/wip1/mobile/oumr.html and https://github.com/marcusgreen/moodle-qtype_gapfill/blob/master/mobile/addon-qtype-gapfill.html (oumr.html is probably a more sensible naming convetion)

Create a file named mobile/addon-qtype-YOURQTYPENAME.html

<section ion-list *ngIf="question.text || question.text === ">

   <ion-item text-wrap>

<core-format-text [component]="component" [componentId]="componentId" [text]="question.text"></core-format-text>

   </ion-item>
   <ion-input padding-left type="text" placeholder="Template:'core.question.answer'" 
   [attr.name]="question.input.name" [value]="question.input.value" autocorrect="off" 
   [disabled]="question.input.readOnly" [ngClass]="[question.input.correctClass]">
   </ion-input>

</section>

classes/output/mobile.php

This file connects PHP with the html/ionic markup template and the mobile.js javascript which contains most of the runtime logic namespace qtype_YOURQTYPENAME\output;

defined('MOODLE_INTERNAL') || die();

class mobile {

class mobile {

   public static function mobile_get_YOURQTYPENAME() {
       global $CFG;
       return [
           'templates' => [
               [
                   'id' => 'main',
                   'html' => file_get_contents($CFG->dirroot .'/question/type/YOURQTYPENAME/mobile/addon-qtype-YOURQTYPENAME.html')
                   ]
           ],
           'javascript' => file_get_contents($CFG->dirroot . '/question/type/YOURQTYPENAME/mobile/mobile.js')
       ];
   }

}

mobile/mobile.js
