### Compatibility

Compatible with MRI Ruby 2.2.0+, and concordant releases of JRuby, and TruffleRuby.
CI workflows and Appraisals are generated for MRI Ruby 2.4+.
This test floor is configured by `ruby.test_minimum` in `.kettle-jem.yml` and
may be higher than the gem's runtime compatibility floor when legacy Rubies are
not practical for the current toolchain.

## ✨ Installation

Install the gem and add to the application's Gemfile by executing:

```console
bundle add snaky_hash
```

If bundler is not being used to manage dependencies, install the gem by executing:

```console
gem install snaky_hash
```

## ⚙️ Configuration

## 🔧 Basic Usage

```ruby
class MySnakedHash < Hashie::Mash
  include SnakyHash::Snake.new(key_type: :string) # or :symbol
end

snake = MySnakedHash.new(:a => "a", "b" => "b", 2 => 2, "VeryFineHat" => "Feathers")
snake.a # => 'a'
snake.b # => 'b'
snake[2] # => 2
snake["2"] # => nil, note that this gem only affects string / symbol keys.
snake.very_fine_hat # => 'Feathers'
snake[:very_fine_hat] # => 'Feathers'
snake["very_fine_hat"] # => 'Feathers'
```

Note above that you can access the values via the string, or symbol.
The `key_type` determines how the key is actually stored, but the hash acts as "indifferent".
Note also that keys which do not respond to `to_sym`, because they don't have a natural conversion to a Symbol,
are left as-is.

### Serialization

```ruby
class MySerializedSnakedHash < Hashie::Mash
  include SnakyHash::Snake.new(
    key_type: :symbol, # default :string
    serializer: true,   # default: false
  )
end

snake = MySerializedSnakedHash.new(:a => "a", "b" => "b", 2 => 2, "VeryFineHat" => "Feathers") # => {a: "a", b: "b", 2 => 2, very_fine_hat: "Feathers"}
dump = MySerializedSnakedHash.dump(snake) # => "{\"a\":\"a\",\"b\":\"b\",\"2\":2,\"very_fine_hat\":\"Feathers\"}"
hydrated = MySerializedSnakedHash.load(dump) # => {a: "a", b: "b", "2": 2, very_fine_hat: "Feathers"}
hydrated.class # => MySerializedSnakedHash
hydrated.a # => 'a'
hydrated.b # => 'b'
hydrated[2] # => nil # NOTE: this is the opposite of snake[2] => 2
hydrated["2"] # => 2 # NOTE: this is the opposite of snake["2"] => nil
hydrated.very_fine_hat # => 'Feathers'
hydrated[:very_fine_hat] # => 'Feathers'
hydrated["very_fine_hat"] # => 'Feathers'
```

Note that the key `VeryFineHat` changed to `very_fine_hat`.
That is indeed the point of this library, so not a bug.

Note that the key `2` changed to `"2"` (because JSON keys are strings).
When the JSON dump was reloaded it did not know to restore it as `2` instead of `"2"`.
This is also not a bug, though if you need different behavior, there is a solution in the [next section](#extensions).

### Extensions

You can write your own arbitrary extensions:

* "Hash Load" extensions operate on the hash and nested hashes
  * use `::load_hash_extensions.add(:extension_name) { |hash| }`
  * since v2.0.2, bugs fixed in v2.0.3
* "Value Load" extensions operate on the values, and nested hashes' values, if any
  * use `::load_value_extensions.add(:extension_name) { |value| }`
  * since v2.0.2, bugs fixed in v2.0.3
* "Hash Dump" extensions operate on the hash and nested hashes
  * use `::dump_hash_extensions.add(:extension_name) { |value| }`
  * since v2.0.3
* "Value Dump" extensions operate on the values, and nested hashes' values, if any
  * use `::dump_value_extensions.add(:extension_name) { |value| }`
  * since v2.0.2, bugs fixed in v2.0.3

#### Example

Let's say I want to really smash up my hash and make it more food-like.

```ruby
class MyExtSnakedHash < Hashie::Mash
  include SnakyHash::Snake.new(
    key_type: :symbol, # default :string
    serializer: true,  # default: false
  )
end

# We could swap all values with indexed apples (obliteraating nested data!)
MyExtSnakedHash.dump_hash_extensions.add(:to_apple) do |value|
  num = 0
  value.transform_values do |_key|
    key = "apple-#{num}"
    num += 1
    key
  end
end

# And then when loading the dump we could convert the yum to pear
MyExtSnakedHash.load_hash_extensions.add(:apple_to_pear) do |value|
  value.transform_keys do |key|
    key.to_s.sub("yum", "pear")
  end
end

# We could swap all index numbers "beet-<number>"
MyExtSnakedHash.dump_value_extensions.add(:to_beet) do |value|
  value.to_s.sub(/(\d+)/) { |match| "beet-#{match[0]}" }
end

# And then when loading the dump we could convert beet to corn
MyExtSnakedHash.load_value_extensions.add(:beet_to_corn) do |value|
  value.to_s.sub("beet", "corn")
end

snake = MyExtSnakedHash.new({"YumBread" => "b", "YumCake" => {"b" => "b"}, "YumBoba" => [1, 2, 3]})
snake # => {yum_bread: "b", yum_cake: {b: "b"}, yum_boba: [1, 2, 3]}
snake.yum_bread # => "b"
snake.yum_cake # => {b: "b"}
snake.yum_boba # => [1, 2, 3]
dump = snake.dump
dump # => "{\"yum_bread\":\"apple-beet-0\",\"yum_cake\":\"apple-beet-1\",\"yum_boba\":\"apple-beet-2\"}"
hydrated = MyExtSnakedHash.load(dump)
hydrated # => {pear_bread: "apple-corn-0", pear_cake: "apple-corn-1", pear_boba: "apple-corn-2"}
```

See the specs for more examples.

### Bad Ideas

I don't recommend using these features... but they exist (for now).

<details>
  <summary>Show me what I should *not* do!</summary>

You can still access the original un-snaked camel keys.
And through them you can even use un-snaked camel methods.
But don't.

```ruby
snake = SnakyHash::StringKeyed["VeryFineHat" => "Feathers"]
snake.key?("VeryFineHat") # => true
snake["VeryFineHat"] # => 'Feathers'
snake.VeryFineHat # => 'Feathers', PLEASE don't do this!!!
snake["VeryFineHat"] = "pop" # Please don't do this... you'll get a warning, and it works (for now), but no guarantees.
# WARN -- : You are setting a key that conflicts with a built-in method MySnakedHash#VeryFineHat defined in MySnakedHash. This can cause unexpected behavior when accessing the key as a property. You can still access the key via the #[] method.
# => "pop"
```

Since you are reading this, here's what to do instead.

```ruby
snake.very_fine_hat = "pop" # => 'pop', do this instead!!!
snake.very_fine_hat # => 'pop'
snake[:very_fine_hat] = "moose" # => 'moose', or do this instead!!!
snake.very_fine_hat # => 'moose'
snake["very_fine_hat"] = "cheese" # => 'cheese', or do this instead!!!
snake.very_fine_hat # => 'cheese'
```

## 🦷 FLOSS Funding

While ruby-oauth tools are free software and will always be, the project would benefit immensely from some funding.
Raising a monthly budget of... "dollars" would make the project more sustainable.

We welcome both individual and corporate sponsors! We also offer a
wide array of funding channels to account for your preferences.
Currently, [Open Collective][🖇osc] is our preferred funding platform.

**If you're working in a company that's making significant use of ruby-oauth tools we'd
appreciate it if you suggest to your company to become a ruby-oauth sponsor.**

You can support the development of ruby-oauth tools via
[GitHub Sponsors][🖇sponsor],
[Liberapay][⛳liberapay],
[PayPal][🖇paypal],
[Open Collective][🖇osc]
and [Tidelift][🏙️entsup-tidelift].

| 📍 NOTE |
|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| If doing a sponsorship in the form of donation is problematic for your company <br/> from an accounting standpoint, we'd recommend the use of Tidelift, <br/> where you can get a support-like subscription instead. |

### Open Collective for Individuals

### Another way to support open-source

I’m driven by a passion to foster a thriving open-source community – a space where people can tackle complex problems, no matter how small. Revitalizing libraries that have fallen into disrepair, and building new libraries focused on solving real-world challenges, are my passions. I was recently affected by layoffs, and the tech jobs market is unwelcoming. I’m reaching out here because your support would significantly aid my efforts to provide for my family, and my farm (11 🐔 chickens, 2 🐶 dogs, 3 🐰 rabbits, 8 🐈‍ cats).

If you work at a company that uses my work, please encourage them to support me as a corporate sponsor. My work on gems you use might show up in `bundle fund`.

I’m developing a new library, [floss_funding][🖇floss-funding-gem], designed to empower open-source developers like myself to get paid for the work we do, in a sustainable way. Please give it a look.

## 📌 Versioning

This library follows [![Semantic Versioning 2.0.0][📌semver-img]][📌semver] for its public API where practical.
For most applications, prefer the [Pessimistic Version Constraint][📌pvc] with two digits of precision.

For example:

```ruby
spec.add_dependency("snaky_hash", "~> 2.0")
```

<details markdown="1">
<summary>📌 Is "Platform Support" part of the public API? More details inside.</summary>

Dropping support for a platform can be a breaking change for affected users.
If a release changes supported platforms, it should be called out clearly in the changelog and versioned with that impact in mind.

To get a better understanding of how SemVer is intended to work over a project's lifetime,
read this article from the creator of SemVer:

## 🤑 A request for help

Maintainers have teeth and need to pay their dentists.
After getting laid off in an RIF in March, and encountering difficulty finding a new one,
I began spending most of my time building open source tools.
I'm hoping to be able to pay for my kids' health insurance this month,
so if you value the work I am doing, I need your support.
Please consider sponsoring me or the project.
