Caller info parameter

Some functions have optional parameters f_ and/or l_ with attribute [CallerFilePath] or [CallerLineNumber]. They automatically pass source file/line info to the function. Usually the caller should not use them.

For example, menus (class popupMenu) and toolbars (class toolbar) use it for the Edit command (context menu). Triggers use it for menu Run > Recent > trigger.

If to add menu/toolbar items or triggers you create an intermediate function, the function should have f_ and/or l_ parameters and pass them to the menu/toolbar/trigger function. Example script:

var m = new popupMenu("431beeab-e190-495a-be8f-05732ef6a74f");
m["Right click me to edit"] = o => print.it(1);
_AddMenuItem("You can edit me too", o => print.it(2));
_AddMenuItemWrongWay("But can be difficult to edit me", o => print.it(3));
m.Show();

void _AddMenuItem(string label, Action<PMItem> action, [CallerLineNumber] int l_ = 0) {
	m[label, l_: l_] = action;
	m.Last.TextColor = 0x0000ff;
}

void _AddMenuItemWrongWay(string label, Action<PMItem> action) {
	m[label] = action;
	m.Last.TextColor = 0xff0000;
}
