Puppet function multi-layer Path transformation array

1. This function is used to split a path of indeterminate length into an array, which can accept two parameters:

1.1 Arg1: A valid absolute path string [not currently checked for data type validity]

1.2 arg2: A valid number to confirm which part is required for puppet creation [[optional] does not make a logical validity judgment, such as passing a number large and the effective level of the path is not reasonable]

2, directly placed in the module corresponding to the Lib/puppet/parser/functions, where the author directly placed in the Stdlib lib/puppet/parser/functions directory

3, the data type is not done and logic error judgment (such as the value range of arg[2])

4. The code and simple use instructions are as follows:

Code:

Module puppet::P arser::functions  newfunction (:p ath_to_array, :type => : Rvalue)  do |args|    res = args[0]         array = []    array.push (Args[0])     if  args.size == 1       while res !=  '/'  do         res = file.dirname (RES)          array.push (res)  if res !=  '/'        End    elsif args.size == 2       e_ count = args[1] - 1      e_count.times do         res = file.dirname (RES)          array.push (RES)  if res !=  '/'       end    end     return array  endend# vim: set ts=2 sw=2 et :

Usage:

1. Vim test.pp

$aaa =['/aaa/bbb/ccc/ddd ', 2] $bbb =path_to_array ($aaa [0]) $CCC =path_to_array ($aaa [0], $aaa [1]) notify{' result_$bbb ': message = [$BBB]}notify{' RESULT_$CCC ': message = [$CCC]}

2, puppet apply TEST.PP
