Convenience library for managing & querying music. Written in Swift.
## Features
* Support music file from `iTunes` library or local file & folder.
* Parse ID3 & `iTunes` format tag information, including -
* artist name
* album name
* genre name
* artwork image, aka. cover image
* duration
* title
* track number
* file url
* Query library by name, artist, album & several other dimensions.
* Persistence store using `CoreData`.
## Design
### Dependencies
Holophonor use `CoreData` as persistence store and use `RxSwift` as databus.
### Concepts
#### MediaItem
A `MediaItem` stands for a media item as its name indicates.
A media item can be a song or a representative item which can represent for an album, an artist or a genre.
`MediaItem` will hold meta data of a song or represented media collection.
`MediaItem` works like `MPMediaItem` in iOS's `MediaPlayer` framework.
#### MediaCollection
A `MediaCollection` is a collection of `MediaItem`.
A `MediaCollection` contains a representative item which contains meta data of this collection.
`MediaCollection` works like `MPMediaItemCollection` in iOS's `MediaPlayer` framework.
#### Representative Item
Representative item is an instance of `MediaItem`, which contains common meta data of a media collection.
Representative item works like `MPMediaItemCollection.representativeItem` in iOS's `MediaPlayer` framework.
#### Meta data
ID3 or iTunes format meta data in music file, which usually contains information like artist name, album name, genre name, track duration & etc.
Meta data can be accessed via `MediaItem` instance.
Complete fields of meta data is listed below.
* albumTitle: Album's title.
* artist: Album's artist.
* fileURL: File's URL.
* filePath: File's absolute path, only applied for local item.
* genre: Genre name.
* mediaType: Media item location - iTunes or local file.
* trackNumber: Track number.
* title: Title for this media item.
* duration: Duration for this media item.
* _itemArtwork: Artwork image for this item. Accessed via `getArtworkWithSize`
* persistentID: Persistent id for this media item
* albumPersistentID: Persistent id for album in database.
* genrePersistentID: Persistent id for genre in database.
* artistPersistentID: Persistent id for artist in database.
* mpPersistentID: `MediaPlayer` persistent id, only applied for iTunes item.
### Structures & Relationships
## Installation
Holophonor is available through [CocoaPods](http://cocoapods.org). To install
it, simply add the following line to your Podfile:
```ruby
pod "Holophonor"
```
## API
### Initialization
Use `Holophonor.instance` to initialize Holophonor and get an instance.
During initialization, Holophonor will save its database file in -
* `Documents` folder for debug build, you can dump the `sqlite` file via `iTunes`.
* `Library` folder for non-debug build.
### Local Directories
Holophonor will search music in local directories and automatically add `Documents` folder to its scan path during initialization.
To add or remove a local directory from scan path, use below functions **before** rescan the library.
```swift
addLocalDirectory(dir: String)
removeLocalDirectory(dir: String)
```
"dir" is the absolute path string of a directory. Also make sure you have access permission for directories you add.
### Rescan Library
You need to perform a rescan action to full fill Holophonor's database.
**A rescan action will drop Holophonor's database** first and search for music files from `iTunes` and local directories.
Call `rescan` function to rescan library.
```swift
rescan(_ force: Bool = false, completion: @escaping () -> Void)
```
You can observe the rescan progress by subscribe the progress subject.
```swift
observeProgress() -> PublishSubject
```
Also you can get a notification when recan started.
```swift
observeRescan() -> PublishSubject
```
### Queries
Use query method like `holophonor.get**By(**: )` to query media items.
## Example
### Get all artist in library
```swift
let foo = self.holo.getAllArtists()
foo.forEach({ (each) in
print((each.representativeItem?.artist)!)
})
```
### Get all albums in library
```swift
let foo = self.holo.getAllAlbums()
foo.forEach({ (item) in
print(item.representativeItem?.albumTitle)
})
```
### Get albums by artist
```swift
let albums = self.holo.getAlbumsBy(artist: "The Killers")
let foo = self.holo.getAllArtists()
let bar = self.holo.getAlbumsBy(artistId: foo.first?.artistPersistentID)
```
### Get songs in album
```swift
let songs = self.holo.getAlbumsBy(artist: "Iron Maiden")?.first.items ?? []
print(songs)
```
### Get meta data in song
```swift
let songs = self.holo.getAlbumsBy(artist: "Iron Maiden")?.first.items ?? []
songs.forEach({ (each) in
print(each.title)
print(each.artist)
print(each.albumTitle)
print(each.getArtworkWithSize(size: CGSize(width: 200, height: 200)) ?? #imageLiteral(resourceName: "ic_album"))
print(each.fileURL)
print(each.genre)
print(each.duration)
print(each.trackNumber)
})
```

## About the name
From [Futurama Wiki](https://futurama.fandom.com/wiki/Holophonor)
*The Holophonor is a musical instrument of the 30th Century, it is best described as a combination of an Oboe and a Holographic Projector.*
*...*
*According to the commentary for Parasites Lost, the holophoner is based on the Visi-Sonor from Isaac Asimov's Foundation Trilogy published in 1951 to 1953. A similiar idea, the Sensory Syrinx, was created by Samuel R. Delany for his novel 'Nova' published in 1968.*
