Wrting a new plugin is often trivial.
Just create a new `channels/name.py` following this structure:
# title: MyPlugin
# description: my radio list
# version: 0.1
# type: channel
# category: radio
from channels import *
class myplugin (ChannelPlugin):
title = "MyNewChannel"
module = "myplugin"
homepage = "http://www.mymusicstation.com/"
has_search = False
titles = dict(listeners=False)
categories = []
catmap = {}
config = []
def update_categories(self):
self.categories = ["Pop", "Rock", "etc"]
def update_streams(self, cat, search=None):
entries = []
# ...
# get it from somewhere
# ...
return entries
The description block on top is used for the plugin management. Some fields like `title` and and `module` are repeated in the class declaration though.
Each plugin needs a `update_categories()` method. This can be a stub, if the channel plugin has a static list of genres. If so, just set the `categories = []` declaration right away. The method is only used if the default categories list is empty, needs to be renewed from the service (e.g. whenever the menu entry Channel>Update_categories is used). There's also a `catmap={}` dict in case category/genre titles have to be associated with service ids.
More importantly you need the `update_streams()` method to fetch station lists. It receives a `cat` parameter, for instance `"Pop"`. Then do whatever API query or website scraping (regex/pyquery) is necessary to populate a list.
Most plugins will return a list of dicts like:
{title: Radio123, url: http://pls, genre: Pop, playing: Song123}
The title is required, and the streaming URL of course. Other fields are mostly optional. (Received data gets stored internally in a `streams={}` dict.)
* Standard fields are: genre, title, url, playing, homepage, bitrate, listeners, favicon. Internal fields are: state, deleted, favourite.
* With a `datamap=[]` declaration custom field names could be displayed.
* Often you just want to rename the column titles however per `title = (listeners="Whatever")` in the class declaration.
