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

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

• Remove runtime dependency on commander.

• Correct a regression of the view feature of the executable.

• Update dependencies and unlock patch version numbers.

• SIGINT is now handled by the executable.

• Correct an issue where an unreadable, untrusted runcom would cause a stacktrace.
• Errors now contain the file subject (eg. ironment: foo: No such file or directory).

• iron exec now handles EACCES, ENOENT & EISDIR like iron trust and iron untrust does.
• iron exec now handles malformed runcom files.

• Correcting a bug under ruby-1.9.3.

• Correcting an error in the gemspec.

• Adding a concept of trust. A file that has never been seen will no longer uncritically be used to populate the environment. Instead, the user will be prompted with its sha1sum and asked if they really want to trust it.

• Initial version. Contains basic support for wrapping commands and populating the environment by recursively reading the directory structure upwards and looking for .envrc files.
