module Puppet::Parser::Functions
newfunction(:split, :type => :rvalue,
:doc => "\
Split a string variable into an array using the specified split regexp.
Usage::
$string = 'v1.v2:v3.v4'
$array_var1 = split($string, ':')
$array_var2 = split($string, '[.]')
$array_var3 = split($string, '[.:]')
$array_var1 now holds the result ['v1.v2', 'v3.v4'],
while $array_var2 holds ['v1', 'v2:v3', 'v4'], and
$array_var3 holds ['v1', 'v2', 'v3', 'v4'].
Note that in the second example, we split on a string that contains
a regexp meta-character (.), and that needs protection. A simple
way to do that for a single character is to enclose it in square
brackets.") do |args|
if args.length != 2
raise Puppet::ParseError, ("split(): wrong number of arguments" +
" (#{args.length}; must be 2)")
end
return args[0].split(Regexp.compile(args[1]))
end
