# tree_reject
[](https://travis-ci.org/salsify/tree_reject)
[](https://badge.fury.io/rb/tree_reject)
`tree_reject` is a Ruby gem that removes deeply nested keys from Ruby Hashes or hash-like objects.
For example:
```ruby
hash = {
a: {
aa: {
aaa: 'aaa',
aab: 'aab'
}
},
b: {
ba: 'ba'
}
}
hash.tree_reject({
a: {
aa: :aaa
}
})
```
results in:
```ruby
{
a: {
aa: {
aab: 'aab'
}
},
b: {
ba: 'ba'
}
}
```
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'tree_reject'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install tree_reject
## Usage
`tree_reject` extends Ruby's built-in `Hash`:
```ruby
my_hash.tree_reject(ignored_keys)
```
It is also available for objects that support `to_h`.
```ruby
TreeReject.tree_reject(my_hash_like, ignored_keys)
```
## Development
After checking out the repo, run `bin/setup` to install dependencies. Then,
run `rake spec` to run the tests. You can also run `bin/console` for an
interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run `bundle exec rake install`.
To release a new version, update the version number in `version.rb`, and then
run `bundle exec rake release`, which will create a git tag for the version,
push git commits and tags, and push the `.gem` file to
[rubygems.org](https://rubygems.org)
.
