hello-chelis

hello-chelis is a self-contained example project that covers the Chelis language and every official shell. It is designed as a self-education tool: clone, run, read.

What it covers

• Language fundamentals: named dimensions, pattern matching, linearity, automatic differentiation, vectorized maps, JIT, macros.
• chelis-std patterns: activations, norms, reductions, losses, Decimal, DateTime, collections, text I/O.
• Shell examples: coral (dataframes), nautilus (scientific computing), octant (LaTeX translation), c-earchin (requirements to property witnesses), school (ML training).
• Capstone projects: Black-Scholes Greeks, linear regression, a transformer block, and a full ML pipeline that crosses shell boundaries.
