def compare_values(ignore_value, incident_value)
  if ignore_value.is_a?(Regexp)
    !ignore_value.match(incident_value.to_s).nil?
  else
    incident_value = incident_value.is_a?(Symbol) ? incident_value.to_s : incident_value
    ignore_value = ignore_value.is_a?(Symbol) ? ignore_value.to_s : ignore_value
    incident_value == ignore_value
  end
end

.normalize_path(path) ⇒ Array

Normalize paths split by File::PATH_SEPARATOR by making sure it always returns an array of paths.

def normalize_path(path)
  if path.is_a?(String)
    path.split(File::PATH_SEPARATOR)
  else
    [path].flatten
  end

.swat_hash(hash, glue = '.', prefix = nil) ⇒ Hash<Symbol, Any>

Swats hash keys and turns them into symbols. See example for what swatting is.

Examples:

Swatting a hash.

swat_hash({
  'foo' => {
    'bar' => 'rab',
    'foo' => {
      'super' => 'nested'
    },
  },
  'extra' => 'value'
}, '_') #=>
{
  :foo_bar => 'rab',
  :foo_foo_super => 'nested',
  :extra => 'value'
}
