EnvCompat

Your tool for converting special characters to ENV friendly variables.

Installation

Add this line to your application's Gemfile:

gem 'env_compat', '~> 0.1'

And then execute:

$ bundle

Or install it yourself as:

$ gem install env_compat

Usage

Three methods are provided :auto, :encode, and :decode. Provide a tag for :auto and it will use that to determine whether or not to encode or decode. You can see this example tag usage in the Bundler library.

EnvCompat.auto :bundle, "https://github.com/company/private-repo.git"
# => "BUNDLE_HTTPS_CFF_GITHUB_D_COM_F_COMPANY_F_PRIVATE_M_REPO_D_GIT" 

EnvCompat.auto :bundle, "BUNDLE_HTTPS_CFF_GITHUB_D_COM_F_COMPANY_F_PRIVATE_M_REPO_D_GIT" 
# => "HTTPS://GITHUB.COM/COMPANY/PRIVATE-REPO.GIT"

EnvCompat.encode "https://github.com/company/private-repo.git"
# => "HTTPS_CFF_GITHUB_D_COM_F_COMPANY_F_PRIVATE_M_REPO_D_GIT" 

EnvCompat.decode "HTTPS_CFF_GITHUB_D_COM_F_COMPANY_F_PRIVATE_M_REPO_D_GIT" 
# => HTTPS://GITHUB.COM/COMPANY/PRIVATE-REPO.GIT

To define your own custom special character mappings feel free to overwrite the EnvCompat module instance method of :mapping. NOTE: When changing mapping the underscore symbol must be mapped.

def EnvCompat.mapping
  {
    '1' => '/', # Forward Slash
    '2' => ':', # Colon
    '3' => '-', # Minus
    '4' => '_', # Underscore
    '5' => '.'  # Dot
  }
end

EnvCompat.encode "https://github.com/company/private-repo.git"
# => "HTTPS_211_GITHUB_5_COM_1_COMPANY_1_PRIVATE_3_REPO_5_GIT"

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test 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.
