CEEFAX

This is a set of Python3 scripts which generate a Ceefax-like teletext service from the following websites:

• BBC News
• BBC Sport
• UK Met Office

It can be configured using the YAML file defaults.yaml.

The output is in the "Viewdata escaped" version of the TTI file format.

Modules required to use

• dateutil, to parse dates from feeds

  sudo apt install python3-dateutil
  

• AdvancedHTMLParser, to extract information from HTML pages

  pip3 install AdvancedHTMLParser
  

  NB. There's a bug in AdvancedHTMLParser: kata198/AdvancedHTMLParser#12

  Run

  pico +1272 ~/.local/lib/python3.7/site-packages/AdvancedHTMLParser/Parser.py
  

  and change "self.useIndex" to "useIndex".

• CacheControl, to cache fetched pages. Filecache stores the contents in the fileystem

  pip3 install CacheControl[filecache]
  

• feedparser, to fetch and parse RSS feeds.

  pip3 install feedparser
  

• PyYAML, to read the configuration file.

  pip3 install PyYAML
  

• MetOffer. Fixed version included here as upstream version has bugs which haven't been fixed for 18 months.
