Issue when parsing a multiline command

errante · January 9, 2025, 3:45am

When using a command splitted in multiple lines as described in the manual, the parsing fails if there is no text after the command's name.

For example, with a test script.
test_multiline_args.opusscriptinstall (1011 Bytes)

(script's code)

function OnInit(initData) {
	initData.name = "test_multiline_args";
	initData.version = "1.0";
	initData.copyright = "";
	initData.desc = "";
	initData.default_enable = true;
	initData.min_version = "13.0";

}

// Called to add commands to Opus
function OnAddCommands(addCmdData) {
	var cmd = addCmdData.AddCommand();
	cmd.name = "test_multiline_args";
	cmd.method = "Ontest_multiline_args";
	cmd.desc = "";
	cmd.label = "test_multiline_args";
	cmd.template = "FILES/M,MULTI/K/R,FILTER/O,OTHERARGS/K/R,ANOTHERARGS/K/R";
	cmd.hide = false;
	cmd.icon = "script";
}

// Implement the test_multiline_args command
function Ontest_multiline_args(scriptCmdData) {
	DOpus.ClearOutput();
	DOpus.Output('cmdline              : ' + scriptCmdData.cmdline);
	DOpus.Output('OTHERARGS            : ' + (scriptCmdData.func.args.got_arg.OTHERARGS ? scriptCmdData.func.args.OTHERARGS : 'nothing'));
	DOpus.Output('FILTER               : ' + (scriptCmdData.func.args.got_arg.FILTER ? scriptCmdData.func.args.FILTER : 'nothing'));
	DOpus.Output('MULTI                : ' + (scriptCmdData.func.args.got_arg.MULTI ? scriptCmdData.func.args.MULTI : 'nothing'));
	DOpus.Output('ANOTHERARGS          : ' + (scriptCmdData.func.args.got_arg.ANOTHERARGS ? scriptCmdData.func.args.ANOTHERARGS : 'nothing'));
}

Using:

test_multiline_args 
[[
MULTI
some random value
]]
[[
OTHERARGS
another random value
]]

Gives:

But if instead you use:

test_multiline_args FILES 
[[
MULTI
some random value
]]
[[
OTHERARGS
another random value
]]

It works if you include something on the same line as the command name—even random text.

test_multiline_args asdfdsf 
[[
MULTI
some random value
]]
[[
OTHERARGS
another random value
]]
