# Run the accessibility testbed against a clean save, WITHOUT destroying the
|
||
|
|
# player's real one.
|
||
|
|
#
|
||
|
|
# The testbed drives a fresh playthrough from the main menu, so it needs the
|
||
|
|
# LOVE save directory empty -- otherwise "Continue" appears, the new-game flow
|
||
|
|
# differs, and the prologue it navigates has already happened. That clean-out
|
||
|
|
# used to be a bare `rm -rf` in the docs, which silently ate a real save every
|
||
|
|
# time someone ran the tests.
|
||
|
|
#
|
||
|
|
# This cannot be done from inside the mod: love.load() reads config, keybindings
|
||
|
|
# and user data long before main.lua reaches our entry point, so by the time any
|
||
|
|
# Lua of ours runs the save directory has already been read. It has to happen
|
||
|
|
# around the process.
|
||
|
|
#
|
||
|
|
# So: MOVE the save aside (never delete it), run, then move it back. The test
|
||
|
|
# run's own save directory is discarded, leaving the tree exactly as it was.
|
||
|
|

# Usage: accessibility/tests/run-testbed.sh [extra love args...]
