Caching sorted script extensions and mod load order

[KANAjetzt]

Currently, two of the heaviest parts of loading mods are being executed even when there are no changes to the installed mods. This results in unnecessary processing and delays in mod loading.

To improve performance, I suggest implementing a caching mechanism for the sorted script extensions and mod load order.

Load Order

godot-mod-loader/addons/mod_loader/mod_loader.gd

Lines 154 to 155 in 6c91c47

	# Sort mod_load_order by the importance score of the mod
	ModLoaderStore.mod_load_order = _ModLoaderDependency.get_load_order(ModLoaderStore.mod_data.values())

Script Extensions

godot-mod-loader/addons/mod_loader/internal/script_extension.gd

Lines 11 to 41 in 6c91c47

	# Couple the extension paths with the parent paths and the extension's mod id
	# in a ScriptExtensionData resource
	static func handle_script_extensions() -> void:
	var script_extension_data_array := []
	for extension_path in ModLoaderStore.script_extensions:
	if not File.new().file_exists(extension_path):
	ModLoaderLog.error("The child script path '%s' does not exist" % [extension_path], LOG_NAME)
	continue
	var child_script = ResourceLoader.load(extension_path)
	var mod_id: String = extension_path.trim_prefix(_ModLoaderPath.get_unpacked_mods_dir_path()).get_slice("/", 0)
	var parent_script: Script = child_script.get_base_script()
	var parent_script_path: String = parent_script.resource_path
	script_extension_data_array.push_back(
	ScriptExtensionData.new(extension_path, parent_script_path, mod_id)
	)
	# Sort the extensions based on dependencies
	script_extension_data_array = _sort_extensions_from_load_order(script_extension_data_array)
	# Inheritance is more important so this called last
	script_extension_data_array.sort_custom(InheritanceSorting, "_check_inheritances")
	# Load and install all extensions
	for extension in script_extension_data_array:
	var script: Script = apply_extension(extension.extension_path)
	_reload_vanilla_child_classes_for(script)
