Crystal Core Language

Aim

To implement minimal requirements for designing CrystalCore grammar and Langium LS during MSc in Huddersfield.

Current requirements (satisfied)

CrystalCore v1 should have:

1. Tiny Classifier lang with typedefs of basic lang types (such as String and Integer), and library BoundaryObjects, such as Console. ∀ BoundaryObject should have just text name (so far). Icons should be added on visualizing phase (e.g., as SVG icon URLs, if CrystalCore lib = github repo, following GoLang idea).
2. Main Behavior lang for defining Operation's behavior:
   • Behavior declaration (Operation's implementation)
   • Variable declaration
   • Variable assignment
   • Constant initialization
   • Value specification (i.e., value literal)
   • Import definition
   • BoundaryOperation invokation

Semantic elements to be included:

• BoundaryOperation (an Operation with no behavior)
• BoundaryObject (a collection of BoundaryOperations)
• Classifier -- currently supports only basic library types, like String or Integer. Full Classifiers support to be included with CrystalCore Classifier feature. The difference between BoundaryObject and Classifier is that the latter can be instantiated. An instance of a library classifier is comparable with BoundaryObject.
