Special Gestures

• Hold the mouse wheel button and scroll to reorder playlists and musics (hold shift to move faster)
• Click on the currently playing track's cover/video to jump to the track in the playlist
• Hover a playlist's cover or the currently playing track's cover/video for a fraction of a second to view it in full screen

Building/Running

On Windows, one can package and run the executable using the build_windows.py script (requires PyInstaller).

It is adviced to run the following commands after configuring a virtual environment. Make sure to be in the folder where the main file is located, then:

pip install -r requirements.txt
py MusicPlayer.py

You can use the health_check.py script to check for unused files in the data folder. Use the --remove argument to delete them automatically. The script is also run when the music player starts.

User data is not stored in AppData or equivalent, rather in the data/ folder where the main file is in.

Hidden Settings

There are 2 settings that can only be accessed in the data/settings.json file.

• "strip_youtube_id": Downloaded videos from youtube might have an ID in square brackets at the end of the filename. If this setting is set to true, such pattern will be stripped from the display name.
• taskbar_height: When this number is different from 0, when the custom titlebar is enabled, it ensures the taskbar is still visible when the window gets maximized. A common value for it is 30. Only works if the taskbar is at the bottom. A (default) value of 0 will result in fullscreen maximized.

Dependencies

• pygame-ce >= 2.5.1 (music, windowing, input, rendering backend)
• mili-ui >= 0.9.7 (UI backend)
• moviepy >= 1.0.3 (video/audio converter/reader)
• [optional] pypresence >= 4.3.0 (Discord presence)
• [optional] PySDL2 >= 0.9.16 (global mouse state backend)

Codebase Notice

The codebase currently follows the following conventions (they are not hard rules):

• __init__ and init(_*) methods are called once.
• Every method starting with ui_ is only responsible for organizing and rendering the UI components. The main ui function of each UI component is split in several subfunctions for ease of readibility.
• Every method starting with action_ is almost certainly a callback that is only called following a user UI interaction, and never called from anywhere else.
• Methods starting with get_, despite the name, are usually called within the same class to change internal states without returning anything.
• Every normal method is used internally by the class and usually by external classes to manage the states.
