[FR] option to override "savename"

[Kariton]

it would be helpful to override the "savename" in script-output.

i use bash to fetch the last changed save game and run mapshot cli on it.
this results in a bunch of autosaveX named mapshots.

# /mapshot/factorio/script-output/mapshot# ls -la
drwxr-xr-x. 7 root root  7 Nov 30 18:07 .
drwxr-xr-x. 3 root root  3 Nov 30 08:33 ..
drwxr-xr-x. 6 root root 11 Dec  1 02:12 _autosave1
drwxr-xr-x. 4 root root  9 Dec  1 00:49 _autosave2
drwxr-xr-x. 6 root root 11 Dec  1 02:38 _autosave3
drwxr-xr-x. 4 root root  9 Nov 30 19:12 _autosave4
drwxr-xr-x. 6 root root 11 Dec  1 02:56 _autosave5

i would love to see a parameter to override this and define a common folder for all mapshots.

i found a way to make it work within my bash script.

move_generated_mapshot() {
	local mapshot_save_path="${1}" # full path to mapshot generated content
	local mapshot_directory_name="${2}" # desired name for "savegame"
	local factorio_save_file_name="${3}" # resulting filename from 'latest' save discovery
	local mapshot_json

	printf "Moving generated mapshot to '%s'...\n" "${mapshot_save_path}"

	mkdir --parents "${mapshot_save_path}"
	mv "${MAPSHOT_OUTPUT_DIRECTORY}/${factorio_save_file_name}"/* "${mapshot_save_path}"

	find "${mapshot_save_path}" -mindepth 2 -maxdepth 2 -type f -name "mapshot.json" |
		while read -r mapshot_json; do
			jq --arg savename "${MAPSHOT_SAVE_NAME}" '.savename = $savename' "${mapshot_json}" >"${mapshot_json}.tmp" &&
				mv "${mapshot_json}.tmp" "${mapshot_json}"
		done
}

move_generated_mapshot "factorio/script-output/mapshot/_autosave5" "my-save-name" "_autosave5"

factorio_save_file_name is the discovered latest save game.
mapshot_save_path is a composition of different variables i use in my script for further processing.
mapshot_directory_name is the name under which the generated mapshots are saved and displayed.
