WithEnv is an extremely small helper module for executing code with ENV variables. It exists because I got tired of re-writing or copying over a #with_env helper method for the 131st time.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install with_env
include WithEnv with_env("FOO" => "BAR") do `echo $FOO` # => "BAR\n" ENV["FOO"] # => "BAR" end # The ENV has been restored to what it was before the # above with_env block, so FOO no longer exists `echo $FOO` # => "\n" ENV.has_key?("FOO") # => false
After checking out the repo, run
bin/setup to install dependencies. Then, run
rake rspec 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.
