Create a list of hash paths that match a given pattern. You can also generate a
hash with only the matching paths.

## Installation

```bash
gem install glob
```

Or add the following line to your project's Gemfile:

```ruby
gem "glob"
```

## Usage

There are two types of paths: `include` and `exclude`.

- The `include` path adds that node to the new hash.
- The `exclude` path is the one started by `!`, and will prevent that path from
  being added.

The latest rules have more precedence; that means that if you have the rule
`*.messages.*`, then add a following rule as `!*.messages.bye`, all
`*.messages.*` but `*.messages.bye` will be included.

```ruby
glob = Glob.new(
  site: {
    settings: {
      name: "Site name",
      url: "https://example.com"
    }
  },
  user: {
    settings: {
      name: "User name"
    }
  }
)

glob << "*.settings.*"

glob.paths
#=> ["site.settings.name", "site.settings.url", "user.settings.name"]

glob.to_h
#=> {
#=>   site: {
#=>     settings: {
#=>       name: "Site name"
#=>     }
#=>   },
#=>   user: {
#=>     settings: {
#=>       name: "User name"
#=>     }
#=>   }
#=> }
```

Notice that the return result will have symbolized keys.
