How to make a module reject invalid parameter

[Philip Brown]

I tried a few google searches on this, and attempted to look through docs.puppetlabs.com, but couldnt find anything...

how do you make a module throw an error for an unrecognized parameter?

ie:

class setitup($machtype) {
  case $machtype {
      prod:  { blah}
      dev:  {blah}
     default: { error Unrecognized machtype parameter value }
  }
}

if !$foo {
  fail 'foo is missing'
}

I think you'll have better luck in the standard library:
https://github.com/puppetlabs/puppetlabs-stdlib

Specifically the validate_*, type, member, and is_* functions are all
for helping validate parameters. Documentation is the in the Readme
and pretty good.


HTH,
