Self‑Hosting Dev (JIT / VM)

Focus: Ny → MIR → MIR‑Interp → VM/JIT quick loops to validate semantics and bootstrap paths.

Quickstart

• Core build (JIT):
  • cargo build --release --features cranelift-jit
• Core smokes (plugins disabled):
  • NYASH_CLI_VERBOSE=1 ./tools/jit_smoke.sh
• Roundtrip (parser pipe + json):
  • ./tools/ny_roundtrip_smoke.sh
• Plugins smoke (optional gate):
  • NYASH_SKIP_TOML_ENV=1 ./tools/smoke_plugins.sh
• Using/Resolver E2E sample (optional):
  • ./tools/using_e2e_smoke.sh (requires --enable-using)
• Bootstrap c0→c1→c1' (optional):
  • ./tools/bootstrap_selfhost_smoke.sh

Flags

• NYASH_DISABLE_PLUGINS=1: stabilize core path
• NYASH_LOAD_NY_PLUGINS=1: enable nyash.toml ny_plugins
• NYASH_ENABLE_USING=1: using/namespace enable
• NYASH_SKIP_TOML_ENV=1: suppress [env] mapping in nyash.toml

Tips

• For debug, set NYASH_CLI_VERBOSE=1.
• Keep temp artifacts under this folder (dev/selfhosting/_tmp/) to avoid polluting repo root.
