# rash
[](https://rubygems.org/gems/rash_alt)
[](https://github.com/shishi/rash_alt/actions?query=workflow%3Arspec)
Rash is an extension to Hashie ( http://github.com/hashie/hashie ).
Rash subclasses Hashie::Mash to convert all keys in the hash to underscore.
The purpose of this is when working w/ Java (or any other apis) that return
hashes (including nested) that have camelCased keys.
You will now be able to access those keys through underscored key names
(camelCase still available).
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'rash_alt', require: 'rash'
```
And then execute:
```shell
$ bundle
```
Or install it yourself as:
```shell
$ gem install rash_alt
```
## Usage
```ruby
@rash = Hashie::Mash::Rash.new({
"varOne" => 1,
"two" => 2,
:three => 3,
:varFour => 4,
"fiveHumpHumps" => 5,
:nested => {
"NestedOne" => "One",
:two => "two",
"nested_three" => "three"
},
"nestedTwo" => {
"nested_two" => 22,
:nestedThree => 23
}
})
@rash.var_one # => 1
@rash.two # => 2
@rash.three # => 3
@rash.var_four # => 4
@rash.five_hump_humps # => 5
@rash.nested.nested_one # => "One"
@rash.nested.two # => "two"
@rash.nested.nested_three # => "three"
@rash.nested_two.nested_two # => 22
@rash.nested_two.nested_three # => 23
```
## Known Issue
You may have Hashie's warnings like this
```
WARN -- : You are setting a key that conflicts with a built-in method Hashie::Mash::Rash#varOne defined in Hashie::Mash::Rash. This can cause unexpected behavior when accessing the key as a property. You can still access the key via the #[] method.
```
if you want to disable this, use `disable_warnings`

## 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.
