This library starts the collection of plugins and extensions I have assembled for the Ruby Sequel library.
The library is in very early infancy stage, so there's not much presently, but what's here is fully covered in specs and tested and used in production-level deployments already.

Currently, sequel_plus contains:

  • plugin for Trees to mimic the Rails acts_as_tree plugin.
  • extension for exporting data using Dataset#export.

NOTE: Authors of other plugins and extensions for Sequel are welcome to contact me for inclusion of your plugin and extension to this project.

Released under MIT license.
