Music Player

A simple GUI music player inspired by foobar2000 written in Rust using egui. The goal of this project is to learn about making gui/ native apps, audio, databases / text search. It is not meant to be used as a serious audio player.

Goals

• Basic music player functionality. Play, pause, stop.
• Create a music library, which is indexed for searching.
• Parse id3 tags from tracks for use with indexing.
• Create playlists, which can be saved, opened, edited, reordered
• Drag n' Drop tracks from the music library into the playlist.
• Save last state of the app when closing.

Stretch goals

• See if I can make right-click context menus.
• Visualizations
• Stream audio
• Swappable frontend so I can try other Rust cross platform gui libaries.
• Scrubbable audio. ie. Keep position in audio and arbitrarily move to any position

Stuff to fix or implement

• Reference playlists by index or actual reference (not a clone...), so info is not lost when changing playlist context
• Double clicking track automatically starts to play it.
• Remove playlists.
• Un-named playlists get (idx) appended
• Playlist tab section stacks playlist tabs when they don't fit.
• Add Next and Previous controls
• Pause is a toggle
• Play restarts the track
• Add volume control slider
• Implement library
• Refactor so the items parsed in the library are the primary data type passed around instead of separate library items and tracks.
• Set currently playing track as app Title
• Display playlist as a table [Playing, Track #, Artist, Album Title, etc... ]
• Add player indicators next to the track
• Improve library build performance and probably offload to a non-ui thread.
• Add toolbar with File, Properties, Help, etc...
• Save app state on close (just get it working bare min with a random file).
• Use Confy for app state load/save
• Refactor into more sensible responsibilities (think components / widgets / features).
• Investigate performance regression with a large library (this is due to sorting/grouping the view on every frame)
• Fix library view performance. Don't need to keep computing the grouping every frame - persist it in app state with a new data structure.
• Fix all egui deprecation errors... should be just one for using CollapsingState instead of CollapsingHeader
• Fix Dark mode now that egui has made some changes in 0.18
• Figure out error handling (anyhow, eyre, thiserror, etc...)
• Remove tracks from playlist.
• Reorder items in playlist.
• Support multiple directories for library
• Figure out how to use at least one hotkey and key event.
• Define key events for the application
• Selected track is highlighted.
• Playlist plays to end after track is selected.
• Save playlists.
• Handle files which can't be decoded correctly into audio.
• Implement library search.
• Differentiate between a selected track and the currently playing one.
• Library display options [ album, artist, year, genre, folder structure, etc...]
• Library Item hashable?
• Discovery on how to make the library state smaller when saved (compression, better data structure, maybe save separate from app state, etc...)
• Surface logs to the user in the UI
• Stop with all the cloning... seriously. Everything is cloned.
