A specification language for Parslet grammars and transformers, which gets translated to RSpec.

The Programming Exercise Markup Language (PEML) is intended to be a simple, easy format for CS and IT instructors of all kinds (college, community college, high school, whatever) to describe programming assignments and activities. We want it to be so easy (and obvious) to use that instructors won't see it as a technological or notational barrier to expressing their assignments. We intend for this format to be something that authors of automated grading tools can adopt, so they can provide a very easy, low-energy onboarding path for existing instructors to get programming activities into such tools. As a result, this notation leans heavily on supporting authors and streamlining common cases, even if this may require more work on the part of tool developers--the goal is to make it super easy for authors of programming activities, not to fit into a specific auto-grader or simplify tasks for tool writers. For more details, see the PEML website.
