A configuration framework

Hi,

I need a framework that will help me make my application configurable.
This framework must save and load the application's configuration
to/from a file. I'm not happy with the System-Settings framework (that
I'm currently using for the Pharo Launcher) that saves executable code
because, when the application evolves, the old code in the
configuration file might not work with the new application.

Is there something around already?

Re: A configuration framework

Yes, there is Sebastian Sastre's ConfigurationFiles which work very well.

I use JSON for that purpose.
Then it's a tree of nested dictionaries. No more than two levels though.

You could also use STON.

I know you asked for a framework, but unless you need something very
specific, JSON is, IMO, the simplest thing that could possibly work.

We use http://smalltalkhub.com/#!/~TaMere/DeployUtils

It loads a JSON files in the "config/" directory sitting next to the image. It handles multi-environment with the "PHARO_ENV" env var.

We use this to have a different configuration in development/staging/production

Check the DUEnvironment class for usage.

Hi Damien,

I use a small extension to SystemSettings which handles checking that the target class exist before executing the setting. However you lose the runOnce ability.
