fifa v1.2 gem - the world's football countries & codes incl. irregulars & non-members

Hello, I’ve updated the fifa gem / library that includes all the world’s football countries and codes (incl. non-member countries and irregular codes). Now you can also get the countries by continental confederations (e.g. Asia, Africa, North & Central America & Caribbean, South America, Oceania, etc.) or (sub)confederations (e.g. Middle East, North Africa, South East Asia, etc. ) and more. Use Fifa.members('UEFA') or Fifa.members('Europe'), for example, to get all 55 countries. Happy data wrangling with ruby. Enjoy the beautiful game. Cheers. Prost.

The steps include: Step 0: Setup - Install the Sport.db Libraries ++ Step 1: Download (or Clone) the CSV Package / Datasets ++ Step 2: Add the Import / Build Script ++ Step 3: Kick off and Run. That’s it. Enjoy the beautiful game. Cheers. Prost.

wikiscript gem - scripts for wikipedia (get wikitext for page, parse tables, etc.)

Hello, I’ve updated the wikiscript library / gem that collects scripts for working with wikipedia articles (e.g. get / fetch the wikitext for a page, parse tables & links, etc. ). Note: I use wikiscript mostly for parsing section headings and tables (for football clubs from around the world), thus, that’s bascially all there is there for now. Happy data wrangling and text processing with ruby. Cheers. Prost.
