Fetching latest commit…

Is your hash in shape? Validates a hash against a (basic) schema.

This was built to support validation of config.yml files with nested keys.


> require 'schema_hash'
> h = { :timeout => 10, :uri => "" }

> h.schema = { :timeout => true }
> h.valid?
=> false

h.schema = { :timeout => true, :uri => true, :key => true }
=> false

h.schema = { :timeout => true, :uri => true }
=> true

Future Ideas

  • Specify optional keys

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.
