More on Configuration

The first, lightly tested, version of fconf is out. At the moment its undocumented, but that should change pretty quickly. Its a otp app that supports multiple simultaneous configurations and merging configs together. It supports everything that I talked about in my last post. Sinan has already been ported over to fconf from its built in configuration system.

Configurations

OTP applications have their own configuration mechanism in the app config structure. However, this doesn't always suit every applications needs. Currently, I have two distinct config mechanisms right now, one for sinan and one for tercio. They share a lot of similarities and I suspect other applications share similar needs. To that end I have split the config system out into its own project, fconf with the intention of using it in both projects. There isn't much out there yet but I should have the config subsystem pulled out of sinan and refactored in the next day or so. There are a few features that I want to support.

• Reloadable config files (maybe auto reloaded)


• Config file syntax agnostic; use the syntax that is right for your user community


• Good, well defined override semantics

Of course, it all needs to be robust and scalable as well. The existing sinan config subsystem supplies most of this. It needs to be converted over to gen_server, create a supervision tree, and convert it to an OTP application.
