viphe / SDL.rb

The Simple Declarative Language provides an easy way to describe lists, maps, and trees of typed data in a compact, easy to read representation. The simple and intuitive API allows you to read, write, and access all the datastructures using a single class. For property files, configuration files, logs, and simple serialization requirements, SDL provides a compelling alternative to XML and Properties files. Implementations are available for Java and .NET; a port to C++ is in the works, with more languages on the way.

date fields beyond normal boundaries (e.g. negative hours) are not supported #1

The Java implementation (which relies on java.util.Calendar) allows unconventional dates like:

2013/2/22 -07:53 2010/2/22 30:65

The Ruby implementation chokes on it with an exception.

The SDL spec doesn't really say much about those cases, but it would be nice if the interoperability was possible.

Did a few tests and:

  1. In java.util.Calendar, each signs on fields work independently: -07:53 means -7 hours +53 minutes and not -7 hours -53 minutes.
  2. In java.util.Calendar, values beyond usual boundaries roll the bigger units (25h means +1d +1h).
  3. Ruby DateTime supports negative hours (down to -24) but it doesn't modify the bigger units (-1h means 23h and not -1d at 23h).
