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:
1 2 3 | when_writing("Building Project") do project.buildend |
The following code will build the project under normal conditions. If the nowrite(true) flag is set, then the example will print:
1 | DRYRUN: Building Project |
instead of actually building the project.
