# ny_selfhost_inline.sh — Ny selfhost inline parser/JSON v0 debug helper
|
||
|
|
#
|
||
|
|
# Purpose:
|
||
|
|
# - Minimal, shell-based equivalent of the inline Ny selfhost pipeline used in src/runner/selfhost.rs.
|
||
|
|
# - Reads a Nyash/Ny source file, runs ParserBox.parse_program2 + EmitterBox.emit_program
|
||
|
|
# via a tiny Hako harness, and prints Program(JSON v0) to stdout.
|
||
|
|
# - Intended for debugging only; not wired into the main CLI or build scripts.
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# tools/ny_selfhost_inline.sh <source.ny> [nyash_binary]
|
||
|
|
# - <source.ny>: Nyash/Ny source file to parse.
|
||
|
|
# - nyash_binary: optional path to hakorune/nyash binary (default: target/release/hakorune or nyash).
|
||
|
|
#
|
||
|
|
# Notes:
|
||
|
|
# - Forces Stage-3 parser ON for the child (NYASH_PARSER_STAGE3=1/HAKO_PARSER_STAGE3=1).
|
||
|
|
# - Enables using resolver with file-based using (dev profile) so that lang.compiler.* modules can be found.
|
||
|
|
# - Does NOT perform Stage-0 prelude text merge or preexpand_at_local; it feeds the raw source to ParserBox.
