( [id://3333]=superdoc: print w/replies, xml ) Need Help??

I am writing a module using Moo. I want the object to have some defaults if values are not specified at creation. Some of the strings are quite long and it is conceivable that they may change. A config file is possible, but that would mean enforcing a directory structure on every machine, Windows or *u*x, which does not appeal to me. I therefore planned to use __DATA__ to hold the strings. There are plenty of warnings on this site not to use __DATA__ in production. Also, it causes problems. If I create two objects, the second comes without the defaults because __DATA__ has already been read. The options as I see them are:

  • 1. Go through the process of resetting __DATA__
  • 2. Memoise __DATA__ in some way.
  • 3. Use a config file.
  • 4. Hard code the strings at the start of the object.

I am minded to use the fourth of these, but would like to know the Monasteriat's recommendations.

Regards,

John Davies
