WikidataPositionHistory

Rewrites Mediawiki pages that include a PositionHolderHistory template, to show a timeline of people who have held a particular office, along with helpful diagnostic warnings for common errors.

Add this line to your application's Gemfile:

gem 'wikidata_position_history', github: 'tmtmtmtm/wikidata-position-history'

And then execute:

$ bundle

WikidataPositionHistory::PageRewriter.new(
   mediawiki_site: 'www.wikidata.org',
   page_title: 'User:Mhl20/Prime_minister_test'
).run!

This looks for a Template call in that page of the form:

{{PositionHolderHistory|id=Q14211}}

If such a template is found, a table is inserted after it listing all people who have held (i.e. have a relevant P39 "position held" statement) position Q14211.

A sentinel HTML comment is also inserted, so that on subsequent runs only the text between the template and that comment are rewritten.

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
