You will need Spotify Premium.
"gspt" uses the Web API from Spotify, which doesn't handle streaming itself. So you'll need either an official Spotify client open or a lighter weight alternative such as spotifyd.
Images are rendered using the Xorg child windows. Currently there is no support for Wayland.
Some Terminals even in Xorg don't seem to support Image rendering. (See Verified Terminals)

Setup

Installing

$ git clone https://github.com/aditya-K2/gspt.git # Cloning
$ cd gspt
$ go build -v # Building
$ sudo install -D gspt -t "/usr/bin/" # Installing

# You can merge them into a one liner
$ git clone https://github.com/aditya-K2/gspt && cd gspt && GOFLAGS="-buildmode=pie -trimpath -mod=readonly -modcacherw" go build -v && sudo install -D gspt -t "/usr/bin/"

Afer Installation Steps

Generate an API Key from Spotify Dashboard

If you want to use Spotify's API to create applications that interact with their music streaming service, you will need an API key. Here's how you can generate one from the Spotify Dashboard:

Go to the Spotify Developer Dashboard and log in with your Spotify account credentials.
Click on the "Create an App" button to create a new application.
Give your application a name and description, and agree to the terms of service. In the Redirect URI section add http://localhost:8080/callback as a callback URL. This is necessary for the OAuth 2.0 authentication flow to work. Click on "Create" to proceed.
On the next page, you'll see the details of your newly created application. In the Settings Look for the section labeled "Client ID" and click on the "Show Client Secret" button. You will now see your Client ID and Client Secret. You will need both of these to use the Spotify API in "gspt"

Using the Generated Credentials

Set the following environment variables from the credentials you generated.

$ export SPOTIFY_ID= # client id
$ export SPOTIFY_SECRET= # client secret

After this you can just run gspt. And follow the link that it generates, and Login.

$ gspt

Command-line Parameters

Usage of ./gspt:
  -c string
        Specify The Directory to check for config.yml file. (default "$XDG_CONFIG_HOME/gspt")
  -hide-image
        Do not display the cover art image.

Configuration

The configuration is done through $XDG_CONFIG_HOME/gspt/config.yml or the path to the folder provided by the -c flag before starting the app. See Command-line Parameters

Also, Configuration is live updated when you make a change except for the Key Mappings.

cache_dir: $XDG_CACHE_HOME

# The amount of milliseconds after which the cover art should be redrawn if there is a event.
redraw_interval: 500

# Do not display the cover art image.
hide_image: false

# Image Drawing related parameters. See next section for an in-detail explanation.
additional_padding_x : 12
additional_padding_y : 16
image_width_extra_x : -1.5
image_width_extra_y : -3.75

# Color configuration has the following api
colors:
    entity:
        fg: # foreground (Can be Hex value or a color name)
        bg: # background (Can be Hex value or a color name)
        bold: # true/false (boolean)
        italic: # true/false (boolean)

# for e.g
colors:
    artist:
        fg: pink
        bg: black # Would be ignored in most of the cases.
        bold: false
        italic: true

# Key mappings has the following API
mappings:
    view:
    function: key_mapping

# for e.g
mappings:
    recently_played_view:
        open_entry: "ctrl-p"

The position of the image without any configuration may vary in different terminals due to font or terminal padding. The app tries to calculate the position based on rows and columns and font width of you terminal but the exact position can't be defined. Therefore, it is recommended to define extra padding and your own image width ratio in the config file. Additional Padding can be positive or negative and can be used to move the image up, down, left, or right. Extra Image width can be adjusted by defining the extra width to be added or subtracted from the original image width.

The additional_padding_x and additional_padding_y configuration parameters allow you to add extra padding to the placement of the image within the terminal window. This additional padding can be set to positive or negative values, which will shift the position of the image accordingly.

Note that the additional_padding_x parameter affects the horizontal placement of the image, with negative values shifting the image to the right and positive values shifting it to the left. Similarly, the additional_padding_y parameter affects the vertical placement of the image, with negative values shifting the image up and positive values shifting it down.

To adjust the additional_padding_x and additional_padding_y parameters, simply modify the configuration file according to your needs. Keep in mind that adding too much padding may cause the image to overlap with other terminal content, while adding too little padding may cause the image to be cut off. Experiment with different values until you find the perfect placement for your image.

Additional Padding

By default, the app assumes that the image preview box has no font or terminal padding or margin, so the image will be rendered at different positions in different terminals. To ensure that the image fits perfectly within the preview box, you can add extra width to the image using the image_width_extra_x and image_width_extra_y configuration parameters. These parameters can be set to positive or negative values to increase or decrease the size of the image, respectively. To add extra width to the image, the app takes into account the font width specified by the variables.

To adjust the image_width_extra_x and image_width_extra_y parameters, simply modify the configuration file according to your needs. Note that these parameters act like a chunk that is either added or subtracted from the original image width. Therefore, if the image is flowing outside the preview box, you may need to adjust the parameters to increase or decrease the chunk size until the image fits perfectly within the box.

Extra Image Width

Configuring Additional Padding and Image Width.

Let's say upon opening "gspt" for the first time and your image is rendered this way.

Here the Y Position is too low hence we have to decrease the additional_padding_y so that image will be rendered in a better position so we decrement the additional_padding_y by 9

Now the configuration becomes

additional_padding_y : 9

and the image appears like this:

One might be happy the way things turn out but you can notice that the image is a little bigger than the box height and hence is overflowing outside the box. Now it's time to change the image_width_extra_y.

Width can be changed by defining the image_width_extra_y and image_width_extra_x it act's a little differently think of it like a chunk which is either added or subtracted from the image's original width. We can look at the configuration and realize that the chunk image_width_extra_y when subtracted from the original image_width doesn't get us the proper result and is a little to low. We need to subtract a more bigger chunk, Hence we will increase the magnitude of image_width_extra_y (or in other words "decrease" image_width_extra_y)

Now the Configuration becomes:

image_width_extra_y : -3.2

and the image appears like this:

Which looks perfect. 🎉
