#
module Puppet::Parser::Functions
newfunction(:reject, type: :rvalue, doc: <<-DOC) do |args|
@summary
This function searches through an array and rejects all elements that match
the provided regular expression.
@return
an array containing all the elements which doesn'' match the provided regular expression
@example **Usage**
reject(['aaa','bbb','ccc','aaaddd'], 'aaa')
Would return: ['bbb','ccc']
> *Note:*
Since Puppet 4.0.0 the same is in general done with the filter function. Here is the equivalence of the reject() function:
['aaa','bbb','ccc','aaaddd'].filter |$x| { $x !~ /aaa/ }
DOC
if args.size != 2
raise Puppet::ParseError,
"reject(): Wrong number of arguments given #{args.size} for 2"
end
ary = args[0]
pattern = Regexp.new(args[1])
ary.grep_v(pattern)
end
end
