2013-10-29(Main) fix typo in pick error messageMatthew Haughton
Update pick error message "at least one non empty value"
2013-09-16enhanced the error message of pick function.Leonardo Rodrigues de Mello
When pick function fail return a better error message like the other stdlib functions, indicating that the error is on function pick. This would help people that see the error to identity it is related to a incorrect use of stdlib function pick, instead of having to grep all puppet libraries and manifests source for the old message. I had also changed the spec test. pick function change spec as suggested GH-179 Fix the spec test to use expect {}.to instead of lambda {}.should as explained by Adrienthebo. "Using expect { }.to is preferred over lambda { }.should. In addition it's best practice to do a string match against the error message to ensure that we're catching the right error, instead of any error of the right type." Also fixed a typo on the error message, it was missing one space. pick function stylish fix as suggested on GH179
2012-11-15Add the pick() functionGary Larizza
This function is similar to a coalesce function in SQL in that it will return the first value in a list of values that is not undefined or an empty string (two things in Puppet that will return a boolean false value). Typically, this function is used to check for a value in the Puppet Dashboard/Enterprise Console, and failover to a default value like the following: $real_jenkins_version = pick($::jenkins_version, '1.449') The value of $real_jenkins_version will first look for a top-scope variable called 'jenkins_version' (note that parameters set in the Puppet Dashboard/ Enterprise Console are brought into Puppet as top-scope variables), and, failing that, will use a default value of 1.449.
