when_writing

when_writing(msg=nil)

Instance Public methods

Use this function to prevent potentially destructive ruby code from running when the :nowrite flag is set.

Example:

when_writing("Building Project") do
  project.build
end

The following code will build the project under normal conditions. If the nowrite(true) flag is set, then the example will print:

DRYRUN: Building Project

instead of actually building the project.
