Jira (PUP-5563) Have the possibility to define a global variable can be update by all modules

Henrik Lindberg commented on PUP-5563   Re: Have the possibility to define a global variable can be update by all modules This goes against the spirit of the Puppet Language since variables are immutable. It is also really bad practice to rely on global variables and the order of evaluation. You can achieve something similar by assigning the count to a variable in your class 'foo'. You can perform this count a number of ways (depending on what you are actually doing in your real code). # get count using stdlib function class foo($hash) { $nbserver = size($hash) $hash.each | $servid| { ... } # the same, but using the fact that 'each' returns the hash class foo($hash) { $nbserver = $hash.each | $servid| { ... }.size # By using reduce if there is conditional logic... class foo($hash) { $nbserver = size($hash) $nbserver = $hash.reduce | $memo, $servid| { if <should be counted condition > { # process $servid $memo +1 } else { $memo } } Instead of referencing the global variable $nbserver, you would reference $foo::nbserver where you want to know the count. I am closing this issue, as we do not plan to add mutable global variables to the Puppet Language.
