### Notes for Python 3.9
Unfortunately I use features that newly git introduced in [Python 3.10](https://docs.python.org/3/library/types.html#types.UnionType).
So unfortunately you **CAN'T** run this programm with python 3.9. [#10][i10]
### Notes for WSL
If you choose to run it in WSL, make sure ` ~/.local/bin` is added to your `$PATH` [#2][i2]

# Programming Interface / Use as Library
This application is $100\%$ centered around Data. Thus the most important thing for working with musik kraken is, to understand how I structured the data.

If you just want to start implementing, then just use the code example, I don't care.
For those who don't want any bugs and use it as intended *(which is recommended, cuz I am only one person so there are defs bugs)* continue reading.

## Appending and Merging data
If you want to append for example a Song to an Album, you obviously need to check beforehand if the Song already exists in the Album, and if so, you need to merge their data in one Song object, to not loose any Information.
This is how I solve this problem:
```mermaid
---
title: "Collection.append(music_object: MusicObject)"
---
flowchart TD
exist("""
<b>Check if music_object already exists.</b>
<hr>
Gets all indexing values with <code>music_object.indexing_values</code>.
If any returned value exists in <code>Collection._attribute_to_object_map</code>,
the music_object exists
""")
subgraph merge["Merging"]
_merge("""merges the passed in object in the already
existing whith <code>existing.merge(new)</code>""")
_map("""In case a new source or something simmilar
has been addet, it maps the existing object again.
""")
_merge --> _map
end
subgraph add["Adding"]
__map("""map the values from <code>music_object.indexing_values</code>
to <code>Collection._attribute_to_object_map</code> by writing
those values in the map as keys, and the class I wanna add as values.
""")
_add("""add the new music object to <code>_data</code>""")
__map --> _add
end
exist-->|"if it doesn't exist"|add --> return
exist-->|"if already exists"|merge --> return
```
This is Implemented in [music_kraken.objects.Collection.append()](documentation/objects.md#collection). The merging which is mentioned in the flowchart is explained in the documentation of [DatabaseObject.merge()](documentation/objects.md#databaseobjectmerge).
The <u>indexing values</u> are defined in the superclass [DatabaseObject](documentation/objects.md#databaseobject) and get implemented for each Object seperately. I will just give as example its implementation for the `Song` class:
```python
@property
def indexing_values(self) -> List[Tuple[str, object]]:
return [
('id', self.id),
('title', self.unified_title),
('barcode', self.barcode),
*[('url', source.url) for source in self.source_collection]
]
```

# How to contribute
I am always happy about pull requests.
If something is missing, like attributes for an object feel free to either add it youreself or open an issue :3
If something is missing, like attributes for an object feel free to either add it yourself or open an issue, if you choose to just change it, beware that something may have to change. :3
If you wanna contribute, this is for you. Some options will follow:
So here is a List of what you can do:
## Add an audio/metadata source
1. [implement a new page like e.g. Soundcloud](#add-a-new-page)
The audio and Metadata Sources all inherint the class `Page` in [abstract.py](src/music_kraken/pages/abstract.py)
## Add a new Page
You can create a subclass of this class for for example youtube or musify or whatever.
I documented the function it should have in the docstrings of [abstract.py](src/music_kraken/pages/abstract.py). If you are unsure about how it works, look at either the doccumentation *(will get more detailed soon)* or an [example](src/music_kraken/pages/encyclopaedia_metallum.py). For trying you're class you can make a skript simmilar to [this one](src/metal_archives.py). Make sure it is in the same directory though.
The audio and Metadata Sources all inherit from the class `Page`, which can be found in [abstract.py](src/music_kraken/pages/abstract.py).
> Read the part of the documentation, I already have written.
You can create a subclass of this class for, for example `YouTube` or `Musify` or whatever.
1. Just create a new file with the name `your_page.py`
in the [page module](src/music_kraken/pages).
2. Then you can simply copy the contents of the [preset](src/music_kraken/pages/preset.py) over to your file.
3. All the functions you need to implement, can be found in the [preset](src/music_kraken/pages/preset.py).
### Important notes
- There is no need to check if you for example added a source of a song twice. I do much post-processing to the data you scrape in the page classes. You can see what exactly I do in [abstract.py](src/music_kraken/pages/abstract.py).
- Use the connection class how it is laid out in the preset to make the request. This will take care of retrying requests, rotating proxies, consistent use of tor (if selected in the config). You have:
- `connection.get()`
- `connection.post()`
- Look at the code of the pages I already have implemented. Namely:
- [musify.club](src/music_kraken/pages/musify.py) _(heavily making use of web scraping)_
- [YouTube](src/music_kraken/pages/youtube.py) _(using both invidious and piped)_
- [Metal Archives](src/music_kraken/pages/youtube.py)
