Announcing Configurator-ng 0.0

Filed under: Uncategorized — lpsmith @ 10:29 pm

I’m pleased to announce a preliminary release of configurator-ng, after spending time writing documentation for it at Hac Phi this past weekend. This release is for the slightly adventurous, but I think that many, especially those who currently use configurator, will find this worthwhile.

This is a massively breaking fork of Bryan O’Sullivan’s configurator package. The configuration file syntax is almost entirely backwards compatible, and mostly forwards compatible as well. However, the application interface used to read configuration files is drastically different. The focus so far has been on a more expressive interface, an interface that is safer in the face of concurrency, and improved error messages. The README offers an overview of the goals and motivations behind this fork, and how it is attempting to satisfy those goals.

I consider this an alpha release, but I am using it in some of my projects and it should be of reasonable quality. The new interfaces I’ve created in the Data.Configurator.Parser and Data.Configurator.FromValue modules should be pretty stable, but I am planning on major breaking changes to the file (re)loading and change notification interfaces inherited from configurator.

Documentation is currently a little sparse, but the README and the preliminary haddocks I hope will be enough to get started. Please don’t hesitate to contact me, via email, IRC (lpsmith on freenode), or GitHub if you have any questions, comments, ideas, needs or problems.
