Cosmo

Cosmo is a statically-typed programming language written in pure Crystal.
We have an extension for VS code (source), however it currently only features syntax highlighting.

Things I Gotta Do

• Stack trace
• Package manager
• Performance boosts lol
• Multiple assignment
• Somehow typecheck blocks before execution
• Fix weird expression parsing ([0].123 evaluates to 0.123??)
• Literal wrapper classes (vector, table)
• Interfaces
• Classes
  • single inheritance
  • mixins
  • visibilities
  • methods
  • $ (this)
• Better type system
  • casting
  • intersections

Things I Might Do

• Make into a VM or compiler
• C bindings

1. Install Crystal.
