module Puppet::Parser::Functions
newfunction(:validate_string, :doc => <<-'ENDHEREDOC') do |args|
Validate that all passed values are string data structures. Abort catalog
compilation if any value fails this check.
The following values will pass:
$my_string = "one two"
validate_string($my_string, 'three')
The following values will fail, causing compilation to abort:
validate_string(true)
validate_string([ 'some', 'array' ])
Note: validate_string(undef) will not fail in this version of the
functions API (incl. current and future parser). Instead, use:
if $var == undef {
fail('...')
}
