application_env

Detect application environments.

Installation

gem install application_env

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

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.

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?
