hflat¶ ↑

This is a simple gem that extends the Hash class with a method to flatten a hash table.

Some examples can be found below and also in the specs.

Install¶ ↑

hflat is available as a gem, so just install using the command below:

$ gem install hflat

Just follow the steps below:

$ git clone git@github.com:carvil/hflat.git

$ cd hflat/

$ gem build hflat.gemspec

$ gem install hflat-0.1.0.gem

The idea of this gem is to convert nested hashed into a flat hash only containing the key/value pairs where the pair is not ah hash.

If one is just interested in the :error_code and the :error_message but doesn’t know the depth, this is a good way of extracting that information:

require 'hflat'

hash = {:fault => { :get_user => {:error_code => 1, :error_message => "User not found"}}}

hash.flatten

This will result in the following hash:

{:error_code=>1, :error_message=>"User not found"}

If you are using older versions of ruby, you might need to require ‘rubygems’ first.

Check out the latest master to make sure the feature hasn’t been implemented or the bug hasn’t been fixed yet
Check out the issue tracker to make sure someone already hasn’t requested it and/or contributed it
Fork the project
Start a feature/bugfix branch
Commit and push until you are happy with your contribution
Make sure to add tests for it. This is important so I don’t break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
