Project description

Dark Keeper

Dark Keeper is open source simple web-parser for podcast-sites.

Goal idea

I like listen IT-podcasts and learn something new. For really good podcasts I want download all episodes. Goal idea is create simple tool for this.

Features

  • [x] simple web-spider walking on site
  • [x] cache for all downloaded pages
  • [x] parse any information from pages
  • [x] export parsed data to MongoDB

Quick start

$ mkvirtualenv keeper

$ workon keeper

(keeper)$ pip install dark-keeper

(keeper)$ cat app.py

from collections import OrderedDict

from pymongo import MongoClient

from dark_keeper import DarkKeeper
from dark_keeper.parse import parse_urls, parse_text, parse_attr


class PodcastKeeper(DarkKeeper):
    base_url = 'https://radio-t.com/archives/'

    mongo_client = MongoClient('localhost', 27017)
    mongo_db_name = 'podcasts'
    mongo_coll_name = 'radio-t.com'

    def parse_menu(self, content):
        urls = parse_urls(content, '#blog-archives h1 a', self.base_url)

        self.menu.append_new_urls(urls)

    def parse_content(self, content):
        row = OrderedDict([])

        row.update({
            'title': parse_text(content, '.hentry .entry-title')
        })
        row.update({
            'desc': parse_text(content, '.hentry .entry-content')
        })
        row.update({
            'mp3': parse_attr(content, '.hentry audio', 'src')
        })

        if row['title'] and row['mp3']:
            self.storage.append_row(row)


if __name__ == '__main__':
    pk = PodcastKeeper()
    pk.run()
