I've just started playing around with AppConfig, and I love it!

As I'm working though, I realize there's a bit of a chicken-and-egg problem, and this isn't specific to AppConfig.

Say I want to use hard-coded default values, config file values and command line arg values. I want config file values to override default values and I want command line args to override both defaults and config file values.

The trick is, I want to specify the config file on the command line. That means I need to get the command line first even though it should be last. The obvious solution is to save the command line values somewhere and re-add them after adding the defaults and config file values.

Is there a better way to handle this?

-Thanks

Update:

Here's what I've come up with, and yes there is a default config file.

  1. Set values to default, including name of config file
  2. Read command line args and store somewhere
  3. If command line specifies config file, and config file does not exist, blow chunks. (If no config file is specified, and the default config file doesn't exist, that's OK.)
  4. If command line specifies config file (and we haven't blown chunks yet) set value of config file
  5. If config file exists, process and set values
  6. Set values from command line that we stored earlier
