Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object (private)

Note:

if the method is an invalid sub-command or if the command fails you will get a Packer::Binary::Command::CommandFailure exception

This method maps Packer::Binary method calls to Packer sub-commands Ex. to run packer build test.json -machine-readable:

Packer::Binary.build('test.json -machine-readable')

Since:

  • 0.2.0
