Make a Music Bar ( listen.moe , mpd , spotify ) using Awesome Window Manager and Lua

0459

Introduction

Hey there everybody !! Before starting, i want to say that this is my first online post, i am writing in my entire life. So please do bear with my silly mistakes or anything wrong i will be writing in this post.

So now going with the flow ; i am an avid music lover and i like the whole idea of development and programming alongside listening to music.

It’s been a year since i migrated to linux ( Btw i use Arch Linux ), and i can’t stress enough, how much my productivity, speed and ease of doing things have increased since then.

My system runs a vanilla arch setup ( barebone arch architecture without any setup ) running Awesome Window Manager. So recently, i thought about making a music bar from scratch. Since Awesome WM is highly configurable and comes with a lot helper utilities, it was really easy to setup such a thing.

  • widget – contains the widgets that collectively make the musicbar widget.

  • musicbar.lua – the overall shell widget / parent widget that contains all other music widgets in widget directory.

  • helpers.lua – contains helper functions needed by many modules.

  • rc.lua – the main file that is executed by awesome on startup.

  • default.jpg – the default image to show if no cover image is available from listen.moe. Like this one :

Prerequisite

Necessary Fonts:

  • Material Design Icons – dropbox

Once you download them and unpack them, place them into ~/.fonts or ~/.local/share/fonts.

  • You will need to create the directory if it does not exist.
  • It does not matter that the actual font files (.ttf) are deep inside multiple directories. They will be detected as long as they can be accessed from ~/.fonts or ~/.local/share/fonts.

Finally, run the following in order for your system to detect the newly installed fonts. 

   fc-cache <span>-v</span>
   fc-cache <span>-v</span>
   fc-cache -v

Making some helper functions 🤝🤝

helpers.lua is a file which contains some functions that are going to be used frequently in this project codebase. These include colorizing text, connecting signals with a defined action, configuring shapes of widgets etc.

Configuring Daemons

Our very first challenge is to make and configure daemons, which will provide us with information and updates over regular interval.

Daemons can be made using the signals library of awesome. Here we have to configure three daemons specifically for ( listen.moe, spotify, mpd )

The daemons will be initiated with an init.lua . Using it we can easily turn on/off a daemon .

init.lua 

<span>require</span><span>(</span><span>"daemon.moe"</span><span>)</span>
<span>require</span><span>(</span><span>"daemon.mpd"</span><span>)</span>
<span>require</span><span>(</span><span>"daemon.spotify"</span><span>)</span>
<span>require</span><span>(</span><span>"daemon.moe"</span><span>)</span>
<span>require</span><span>(</span><span>"daemon.mpd"</span><span>)</span>
<span>require</span><span>(</span><span>"daemon.spotify"</span><span>)</span>
require("daemon.moe")
require("daemon.mpd")
require("daemon.spotify")

Firstly, we are requiring the ‘awful’ library for spawning process here. The function emit_info takes the stdout of a python script (moe.py – a python script which establishes a web socket connection with listen.moe and writes data on song change ) , grabs the necessary information out of it and emits a signal with that information.

The moe.py script can be placed anywhere but you should update it’s path in the local moe_script. Next we use awful.spawn to kill the python script process ( moe.py ) if it already exists ( in case of restart of awesome ).

After that in the callback function we use awful.spawn.with_line_callback to asynchronously read each line generated by the moe.py script and call emit_info function for that line to grab the necessary information out of it to emit a signal.

Additionaly the moe.py script that provides the information for moe daemon :

The script when run establishes a web socket connection to a dedicated listen.moe web socket server. The script sleeps 30 sec if no internet connection is established and then fires again to establish the connection.

The script receives a json response object from which we extract the artist name, title name and the cover image endpoint. Images are downloaded using the cover image endpoint with wget python package. The path variable holds the download directory for images and should be updated to your preference in the script.

Some may prefer keeping the covers of the song, but i usually don’t like saving them. So i added a cronjob to remove these images on every reboot. 

@reboot rm /home/lucifer/projects/*.{png,jpg,jpeg,tmp}
@reboot rm /home/lucifer/projects/*.{png,jpg,jpeg,tmp}

spotify.lua takes the stdout from playerctl ( A utility command line tool to control MPRIS-enabled media players ). You need to have playerctl installed to make it work.

The script is very much alike to moe.lua except that it depends on playerctl for obtain information regarding the status of spotify player ( song name, album name, playing status ).

mpd.lua script provides us with updates from our mpd client regarding ( song name, album name, player status, volume, random/loop enabled ). The script uses mpc ( command line client for MPD player ) to read the status of MPD player.

To get subscribed to events of MPD player, we use the mpc idleloop. Thus on any event ( song change, volume up, pause ) we get some feedback over which we can implement some action based on the event that occoured.

There are 3 signals being generated by the mpd.lua ( song status , volume status , options status ). I basically use the first one only ( song status ), but you can also use the other two to get subscribed about the volume and option updates as well.

Making Widgets

Now that we have configured our daemons, our next task is to make widgets for displaying the information provided to us. Our widgets will depend upon these daemons to update their state and change themselves based on subscribed events.

There are 5 widgets we are going to make :

  1. moe.lua
  2. spotify_song.lua
  3. spotify_buttons.lua
  4. mpd_song.lua
  5. mpd_buttons.lua

moe.lua returns the listen.moe widget for the musicbar. The libraries include :

  • awful -> For buttons and spawning processes.
  • wibox -> The main widget box library.
  • naughty -> The notification library.
  • helpers -> The user defined helper library.

The file consists of moe_playing_colors which are essentially theme colors taken from xrdb and are defined in rc.lua ( later in this post ). Alongside we have a local variable default image which is basically a image that is put in place of cover image if it’s not available.

Next we have created 1 imagebox and 4 textbox for imagecover, song title, artist title, play icon and listener count.

moe_play_icon:buttons control the action when the icon is clicked. When it does, it fires a shell script ‘moe’ ( defined below ) which plays the music from listen.moe using mpv player as a background process.

You can either install the fonts defined in {textbox}.font or change them according to your preference.

moe_widget is our main listen.moe widget which consists of all individual wibox widgets ( cover image, song title, artist title, play icon, listeners count ).

For subscribing to the daemon updates ( daemon/moe.lua ), we use the awesome.connect_signal and based on the information update our widget state.

Additionaly the shell script moe : 

<span>#!/bin/sh</span>
<span>moe</span><span>=</span><span>"https://listen.moe/stream"</span>
pkill <span>-f</span> <span>$moe</span> <span>||</span> mpv <span>"</span><span>$moe</span><span>"</span>
<span>#!/bin/sh</span>

<span>moe</span><span>=</span><span>"https://listen.moe/stream"</span>

pkill <span>-f</span> <span>$moe</span> <span>||</span> mpv <span>"</span><span>$moe</span><span>"</span>
#!/bin/sh

moe="https://listen.moe/stream"

pkill -f $moe || mpv "$moe"

Keep in mind you need to add this script to your path to make it available everywhere.

spotify.lua returns the spotify song widget which contains the song artist and song title.

The code is very much similar to moe.lua widget except that here we are connecting to the daemon::spotify signal.

Since spotify already notifies us about song changes i do not like receiving extra notification, thus i commented out the notification line in awesome.connect_signal. This is just to avoid getting 2 notifications.

spotify_buttons.lua contains the buttons for controlling the spotify directly from your musicbar.

The play/pause, previous, next icons are binded to certain action. The playerctl utility is the tool which is used for carrying out these actions ( pause/play, next song, previous song ).

The color of the icons changes when a song is playing. The colors are randomly picked from an array music_playing_colors.

mpd_buttons.lua returns the widget for button control for controlling you MPD client straight from musicbar. It has the same spotify_buttons.lua buttons.

However, one minor change in mpd_buttons.lua is that it keeps track of the last color used and thus doesn’t display same color twice in succession for the icons color.

Putting together the Musicbar

Now that we have finally configured all our daemons and widgets, it is finally time to assemble the full musicbar with these widgets and daemons.

The music bar is erected on the right side of my screen and pops out when i hover the mouse pointer over the right edge.
