/*
API : les développeurs peuvent créer des "plugins" pour JVChat à l'aide d'un système d'évènements.
Cela permet par exemple à un deuxième userscript de modifier les messages au moment où ils sont
ajoutés par JVChat, afin que chacun puisse personnaliser son affichage et ajouter de nouvelles
fonctionnalités.

Pour cela, il suffit d'écouter l'évènement "jvchat:newmessage". Celui-ci est émis chaque fois
qu'un novueau message est ajouté, il contient l'identifiant dudit message à récupérer dans le DOM
via le data-attribut "jvchat-id".

Il existe aussi l'évènement "jvchat:activation" qui est émis une seule fois : à l'initialisation
lorsque le topic pass en mode "JVChat" après appui sur le bouton.

L'évènement "jvchat:activated" qui est émis une seule fois : après l'initialisation
lorsque les messages sont chargés.

Il existe enfin l'évènement "jvchat:postmessage". Celui-ci est émis chaque fois qu'un message est posté par l'utilisateur actuel.
Il contient l'identifiant du message, le contenu du message, et l'auteur du message.

Exemple pour cacher les messages qui contiennent certains mot-clefs:

    // my_plugin.user.js
    let keywords = ["foobar", "barbaz"]

    addEventListener("jvchat:newmessage", function(event) {
        // L'id du message est stocké dans event.detail.id
        // L'attribut event.detail.isEdit est mis à "true" s'il s'agit d'un message édité
        let message = document.querySelector(`.jvchat-message[jvchat-id="${event.detail.id}"]`);
        let text = message.querySelector(".txt-msg").textContent;
        for (let keyword of keywords) {
            if (text.includes(keyword)) {
                message.style.display = "none";
                return;
            }
        }
    });
