Feature request: train all chapters together

[francvoc]

A small additional feature I would find very useful.

When I train a study, there is a drop box to choose the chapter. You may want to add an entry to the drop box, with "full study", to train all chapters at once. When starting a new line, your program would choose at random from the various chapters, and then again at random which line to choose.

Thank you again for your work!

I have written a small js-script with wich you get a random chapter every time you click a button "Random Chapter".
You can paste it into a tampermonkey script (browser extension) and you will get this feature.
By time I will write a script where a random chapter is selected every time a practise is complete.

// ==UserScript==
// @name         Random chapter button
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  try to take over the world!
// @author       You

// @icon         https://www.google.com/s2/favicons?sz=64&domain=listudy.org

// ==/UserScript==

(function() {
    'use strict';

    let select = document.getElementById('chapter_select');

    document.getElementsByClassName('container')[1].children[2].innerText = select[select.value].innerText

    let button = document.createElement("BUTTON");
    button.setAttribute("id", "button");
    button.textContent = "Random chapter"

    let chapterSelection = document.getElementsByClassName('chapter_selection')[0]
    chapterSelection.appendChild(button)

    let button_element = document.getElementById('button')

    button_element.onclick = function() {
        for(let i = 0; i < select.length; i++) {
            select[i].selected = false
        }
        var choosen_chapter = select[Math.floor(Math.random() * select.length)];
        choosen_chapter.selected = true
        select.onchange()
        // Update main-titel
        document.getElementsByClassName('container')[1].children[2].innerText = select[select.value].innerText
    }
})();

The following js-script lets you train all your chapters at once. Every time when you finish a chapter with success, a new chapter is chosen.

// ==UserScript==
// @name         New Chapter after success
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  try to take over the world!
// @author       You
// @match        https://listudy.org/de/studies/x14gpe-1001-checkmates
// @icon         https://www.google.com/s2/favicons?sz=64&domain=listudy.org
// @grant        none
// ==/UserScript==

(function() {
    'use strict';

    let select = document.getElementById('chapter_select');
    let currentChapter = window.chapter
    let first_move_played = false

    document.getElementsByClassName('container')[1].children[2].innerText = select[select.value].innerText

    let succes_text = document.getElementById('success_text')
    var config = { childList: true };

    function updateChapter() {
        if(window.curr_move.length === 1 && first_move_played) {
            for(let i = 0; i < select.length; i++) {
                select[i].selected = false
            }
            let choosen_chapter = select[Math.floor(Math.random() * select.length)];
            choosen_chapter.selected = true
            document.getElementsByClassName('container')[1].children[2].innerText = select[select.value].innerText
            currentChapter = window.chapter
            first_move_played = false
            select.onchange()
        }
        else if(window.curr_move.length > 1) {
            first_move_played = true
        }
    }

    var observer = new MutationObserver(function(mutations) {
    mutations.forEach(function(mutationRecord) {
        updateChapter()
       });
    });

    observer.observe(succes_text, config)
})();

FYI. I have used ChessTempo to merge chapters into one. Import the PGN file into ChessTempo.com's opening trainer, and then export it and it will come out as one "chapter".
