I am writing a Tk program that allows users to save various options, such as colors in the GUI and paths for stored files. I would like these options to be restored when the user runs the program again. So I need a persistence mechanism for the options, perhaps like an old-fashioned options .Xdefaults file. I'm guessing that the .Xdefaults file format is now less popular than it once was.

What is the preferred way to store these options?

So far I am considering Data::Denter, Data::Dumper, Storable, XML, and .Xdefaults formats. I could use one of these file formats to store a hash that holds all the option information.

I would like to hear opinions on the best way to do this, and what CPAN modules provide easy-to-implement support for remembering user configuration information.

It should work perfectly the first time! - toma
