    1er avril 2010, par

    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Discord bot returning odd error message and not playing sound

    26 février 2020, par Ravenr_

    I am attempting to create a function of my discord bot that will join your voice channel then play something from youtube as specified in the command

    i.e. $play <youtube link="link"></youtube>

    The problem is that my bot joins the voice channel but doesn’t play any sound and outputs an error to the console that I dont know how to fix

    My Code :

    const ytdl = require("ytdl-core");
    
module.exports = {
    
    name: 'play',
    
    description: 'initiates music methods of the bot',
    
    execute(msg, args){
    
        var servers = {};
    

    
        function play(connection, msg){
    
            var server = servers[msg.guild.id];
    

    
            server.dispatcher = connection.playStream(ytdl(server.queue[0], {filter: "audioonly"}));
    
            server.queue.shift();
    

    
            server.dispatcher.on("end", function(){
    
                if(server.queue[0]){
    
                    play(connection, msg);
    
                }else{
    
                    connection.disconnect();
    
                }
    
            });
    

    

    
        }
    
        if(!args[1]){
    
            return msg.channel.send("you need to provide a link");
    
        } 
    
        if(!msg.member.voiceChannel){
    
            return msg.channel.send("You must be in a voice channel to use this feature");
    
        }
    
        if(!servers[msg.guild.id]) servers[msg.guild.id] = {
    
            queue: []
    
        }
    
        var server = servers[msg.guild.id];
    
        server.queue.push(args[1]);
    
        if(!msg.guild.voiceConnection) msg.member.voiceChannel.join().then(function(connection){
    
            play(connection, msg);
    
        })
    
    }
    
}

    for reference these are the links I tested it with 1 & 2

    I’m not sure how to make queue[0] a string, which is what I assume the problem is.

    I was thinking of using a toString() i.e. server.queue[0].toString() but I think that will just return the memory address.

    If anyone can help me know what the issue is or how to fix it, that would be great.
