-module Puppet::Parser::Functions
- newfunction(:join, :type => :rvalue, :doc => <<-EOS
-This function will allow to concatenate elements of an array together
-with a given suffix and optionally with prefix if such is given ...
-
-For example:
-
-Given the following sample manifest:
-
- define iterator {
- notice $name
- }
-
- $array = ['a', 'b', 'c']
-
- $result = split(join($array, ',', 'letter_'), ',')
-
- notice $result
-
- iterator { $result: }
-
-This will produce the following:
-
- notice: Scope(Class[main]): letter_a letter_b letter_c
- notice: Scope(Iterator[letter_a]): letter_a
- notice: Scope(Iterator[letter_b]): letter_b
- notice: Scope(Iterator[letter_c]): letter_c
-
-Which allows you to avoid resorting to the following:
-
- $result = split(inline_template("<%= array.collect { |i| \"letter_#{i}\" }.join(',') %>"), ',')
-
-Phasing out the need for use and abuse of the infamous inline_template
-in the example above and which in this very case is extremely ugly as
-we have to escape double-quotes to make Puppet parser not evaluate them.
