joeylib2/scripts/test-agi.sh

#!/usr/bin/env bash
# Host-side regression tests for the AGI port.
#
# Compiles tests/agi/testAgiRes.c + examples/agi/agiRes.c with the
# host gcc and runs it against every game directory in
# examples/agi/gamedata/. Each game is exercised in isolation; the
# script aggregates pass/fail counts and exits non-zero if any test
# fails.
#
# Why a host build instead of running the emulator binaries: the AGI
# resource loader is plain stdio C with no platform dependencies, so
# the parsing logic is identical on every JoeyLib target. Validating
# it on the build host means each iteration takes a second instead
# of the 15-30s of an emulator boot, and reproducible failures don't
# depend on capturing video / log output through DOSBox or MAME.
#
# Usage:
#   scripts/test-agi.sh                # test every subdir of gamedata/
#   scripts/test-agi.sh kq3 agidemo    # test only the named subdirs

# Pick a JoeyLib platform for the host build. None of the platform-
# specific code paths are exercised by the host test (it only touches
# the AGI parsers, never the JoeyLib HAL), but joey/platform.h #errors
# unless exactly one is defined. DOS is the closest fit for a Linux
# host (chunky, little-endian, x86 lineage).
