Detect application environments.
## Installation
```bash
gem install application_env
```
Or add the following line to your project's Gemfile:
```ruby
gem "application_env"
```
## Usage
The environment is inferred out of `ENV["APP_ENV"]`, `ENV["RACK_ENV"]`,
`ENV["RAILS_ENV"]`, defaulting to `development` in case no environment is set.
```ruby
require "application_env"
app_env = AppEnv.new
app_env.development?
app_env.test?
app_env.production?
# runs block on production.
app_env.on(:production, &block)
# runs block on any environment.
app_env.on(:any, &block)
# pass in custom env vars
app_env = AppEnv.new({"APP_ENV" => "development"})
# sets up custom accessors
app_env = AppEnv.new(ENV, accessors: %i[development test staging production])
app_env.staging?
```
