Introduce a Source::URL class for parsing URLs from source sites. Refactor the Twitter
source strategy to use it.
This is the first step towards factoring all the URL parsing logic out of source
strategies and moving it to subclasses of Source::URL. Each site will have a subclass
of Source::URL dedicated to parsing URLs from that site. Source strategies will use
these classes to extract information from URLs.
This is to simplify source strategies. Most sites have many different URL formats we have
to parse or rewrite, and handling all these different cases tends to make source
strategies very complex. Isolating the URL parsing logic from the site scraping logic
should make source strategies easier to maintain.
This directory contains library code used through Danbooru. This includes things like defining API clients, dealing with
sources, parsing tag searches, storing and resizing images, and so on.
Many of the files here use the Service Object pattern. Instead of putting complex code in models or controllers, it goes
here, in plain old Ruby objects (POROs). This keeps models and controllers simpler, and keeps domain logic isolated and
independent from the database and the HTTP request cycle.
