Hybrid Selfhost Build (80/20)
Purpose
- Provide a minimal, fast path to compile Hako source via Hakorune Stage‑B to Program(JSON v0), and optionally run it via Core‑Direct (in‑proc).
- Future: add MIR emit and ny-llvmc EXE build in small increments.
Script
- tools/selfhost/selfhost_build.sh
- --in <file.hako>: input Hako source
- --json <out.json>: write Program(JSON v0); default: /tmp/hako_stageb_$$.json
- --mir <out.json>: emit MIR(JSON) from source (runner path)
- --exe : build native executable via ny-llvmc (llvmlite harness)
- --run: run via Gate‑C/Core Direct (in‑proc). Exit code mirrors program return.
- Env:
- NYASH_BIN: path to hakorune/nyash binary (auto-detected)
- NYASH_ROOT: repo root (auto-detected)
- HAKO_USE_BUILDBOX=1: use BuildBox for emit-only (no run/exe)
Examples
# Emit JSON only (Stage‑B)
tools/selfhost/selfhost_build.sh --in apps/demo/main.hako --json /tmp/demo.json
# Run and use exit code
tools/selfhost/selfhost_build.sh --in apps/demo/return7.hako --run; echo $?
Notes
- Stage‑B emit uses either the Stage‑B entry or BuildBox（HAKO_USE_BUILDBOX=1 for emit-only）
- Runner executes Core‑Direct in-proc under HAKO_CORE_DIRECT_INPROC=1.
- For heavier cases (bundles/alias/require), keep Stage‑B canaries opt‑in in quick profile.
