How to create a Playlist as File

No Name Pro — Thu, 30 Jul 2020 12:39:35 +0000

Hello 👋

you want to create a playlist for a party to a file which runs on every PC?

The best way is a XSPF-File.
It's simply just a XML File. JSON?

I know it, it's nothing for development. But i think this article can for many people be helpfull

Create a file

First create a File named playlist.xspf with this content.

<?xml version="1.0" encoding="UTF-8"?>
<playlist version="1" xmlns="http://xspf.org/ns/0/">
    <trackList>
        <track><location>Song.mp3</location></track>
        <track><location>Directory/AnotherSong.mp3</location></track>
        <track><location>SongWith%20Space.mp3</location></track>
        <track><location>http://song.from/internet.mp3</location></track>
    </trackList>
</playlist>

Add some Metatags

If you want to add some metatags to the playlist, open the file and add in the <playlist>-Element:

<!-- title of the playlist -->
<title>My best tracks for the party</title>

<!-- name of the author -->
<creator>No Name Pro</creator>

<!-- website of the author -->
<info>https://dev.to/nonamepro0</info>

And add Meta-Tags (like Custom-Name) for the Tracks in the <track>-Element:

<!-- artist or band name -->
<creator>Led Zeppelin</creator>

<!-- album title -->
<album>Houses of the Holy</album>

<!-- name of the song -->
<title>No Quarter</title>

<!-- comment on the song -->
<annotation>I love this song</annotation>

<!-- song length, in milliseconds -->
<duration>271066</duration>

<!-- album art -->
<image>http://images.amazon.com/images/P/B000002J0B.01.MZZZZZZZ.jpg</image>

<!-- if this is a deep link, URL of the original web page -->
<info>http://example.com</info>

Check if playable

You can open this File with VLC to check if the File is readable and playable for the XSPF Format.

You can use another app, which is listed here: https://xspf.org/applications/

If you want a JSON (`JSPF`)

Check out: https://xspf.org/jspf/

If you have questions

Then write a comment or check the offical informations from XSPF out: https://xspf.org/

Keep every Glitch.com-Project up

How it works

The HTTP-Listener below opens a Port. So if a user send a HTTP-Request to your Page, this Listener will answer.
A normal free Glich.com Project shutdown automatically when 5 minutes no Request will send to the App.

Method 1: Go to this page every 5 minutest with your browser, to keep your project alive.

But, we all know, it's not a very good method.

So, this tool up will send automatic using crontab every 5 Minutes a HTTP-Request to your Listner.

So your server needs just every 5 Minutes a very small progess, and your NodeJS-Application runs 24/7 with the Performance from the Glitch-Servers.

It's just a small server needed, if you don't have a server, i suggest a Raspberry Pi or ask a friend! :D

I will update this article, if i find better soulutions. But the old, works too.

Setup

`HTTP-Listener`: Set to your NodeJS Applicaion

Just add to your server.js this code. No config is here needed.

let express = require("express"),
    http = require('http'),
    app = express();

app.use(express.static("public"));
app.get("/", function(request, response) {
  response.sendStatus(200); // Status: OK
});

let listener = app.listen(process.env.PORT, function() {
  console.log("Your app is listening on port " + listener.address().port);
});

setInterval(() => {
  http.get(`http://${process.env.PROJECT_DOMAIN}.glitch.me/`);
}, 280000);

`Automatic HTTP-Request`: Run on your Server

Run this commands in the Bash. But: Change in the First Line the my-example-nodejs to your Project Name.

PROJECT=my-example-nodejs

echo "5 * * * * curl https://$PROJECT.glitch.me/" > /etc/cron.d/glitch-up
service restart cron

Python - Simple and beautiful

Hello 👋

I want to show you, what Python works. How to write functions and if's.

I'm new in Python, i previous worked with C# and other languages which have a compiler.

Python don't needs a compiler. It's an script language. The good is, you can code everywhere and just need to run this file.

But if you code a error, for example Syntax-Error, the program neeeds to go to the line. A Compiler check this on compiling and will show it.

Define a variable

# Define a boolean
MyVariable = True

# Define a string
WelcomeText = "Welcome"

# Define a array
Names = ['Some', 'Body']

Print/Write to Console

# Print a defined text
print("I am at the Console!")

# Print a string
print(WelcomeText)

# Print a multiple Strings/Text
print(WelcomeText + ' User')

If-Clauses

if MyVariable == True:
    # Do something

Functions

# Define a new function
def Welcome:
    print(WelcomeText)

# Run Function
Welcome()

For Loops

for user in names:
    print(WelcomeText + ' ' + user)

So yeah 🎉

Python is a beatiful language, what mean formatting.

I think it's easy to understand, and i would use Python for small scripts for Linux, Windows and macOS.

For more help, ask me or search in the world-wide-web.
