Module: Beaker::DSL::Wrappers
- Included in:
- Beaker::DSL, PSWindows::Exec
- Defined in:
- lib/beaker/dsl/wrappers.rb
Overview
These are wrappers to equivalent Command objects so that command line actions are executed within an appropriate and configurable environment.
I find most of these adapters of suspicious value and have deprecated many of them.

#encode_command(cmd) ⇒ String
This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.
