Ndhash

N-dimension hash creation and utilities. Useful for testing multi-level hash and JSON processing.

Add this line to your application's Gemfile:

gem 'ndhash'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ndhash

require 'ndhash'

# Generate hash with custom number of levels, number of key-value pairs and hashes per level
NDHash.generate(levels:2, values_per_level:2, hashes_per_level:2)

{
    "level_1_key_1": "level_1_value_1",
    "level_1_key_2": "level_1_value_2",
    "level_1_pointer_1": {
        "level_2_key_1": "level_2_value_1",
        "level_2_key_2": "level_2_value_2"
    },
    "level_1_pointer_2": {
        "level_2_key_1": "level_2_value_1",
        "level_2_key_2": "level_2_value_2"
    }
}

NDHash.generate(levels:2, values_per_level:0, hashes_per_level:2)

{
    "level_1_pointer_1": {},
    "level_1_pointer_2": {}
}

# Count number of nested levels per hash
NDHash.count_levels({key:{}}})
# => 2

Any feedback is much appreciated.

I can only tailor this project to fit use-cases I know about - which are usually my own ones. If you find that this might be the right direction to solve your problem too but you find that it's suboptimal or lacks features don't hesitate to contact me.

Please let me know if you make use of this project so that I can prioritize further efforts.
