Ironment

Ironment is a simple command line utility for populating the environment of a command by reading particular environment files and then exec-ing. Such environment files may look like the following.

# ./.envrc
FOO=bar

Any command wrapped with iron will see the environment variables.

$ iron env
FOO=bar

Installation

The utility can be installed using gem.

$ gem install ironment

It can be installed system-wide using the following options.

$ gem install --no-user-install -i "$(ruby -e'puts Gem.default_dir')" -n /usr/local/bin ironment

It is also packaged for Arch Linux.

$ yaourt -S ruby-ironment
