Overview

This monorepo contains 12 programming languages + 2 meta-projects. All 12 languages are registered in the BoJ Server lang-mcp cartridge with session management, type-checking, and evaluation via V-lang adapter + Zig FFI.

Related BoJ Cartridges

• lang-mcp — Language sessions (V-lang adapter, Zig FFI, PanLL panels)

• lsp-mcp — Generic LSP proxy (ABI/FFI/adapter/panels)

• dap-mcp — Generic DAP proxy (ABI/FFI/adapter/panels)

Julia-the-Viper Dialect Injection

Any language can be augmented with JtV by requesting dialect jtv:

• API: lang_session_start_dialect(lang_id, 1, name) where 1 = JtV

• Shorthand: "eclexia+jtv", "betlang+jtv", "affinescript+jtv", etc.

ABI/FFI Standard (Idris2 + Zig)

Language	Idris2 ABI	Zig FFI	Status
AffineScript	src/abi/ (Types, Layout, Foreign)	planned	In progress
Julia-the-Viper	src/abi/ (Types, Layout, Foreign)	planned	In progress
Ephapax	ephapax-proven (3 crates)	proven-ffi	Complete
Others	—	—	Not started

Formal Verification

• Ephapax — Linear type proofs via Idris2

• AffineScript — Affine type proofs (linear subset)

• Eclexia — Effect system proofs (eclexia-effects crate)

Meta-Projects

• 7-Tentacles — Game development curriculum using nextgen languages

• Anvomidav — Stub (19 files, minimal)
