# @summary A function that calls the _() function in gettext. This is because _ is protected in the puppet language
#
# @note
# Translate with simple strings:
# - Takes in a string and passes it to fast_gettext's _() function. Primarily used for 'marking' a string to be added to a .pot file.
# Translate with interpolation:
# - Takes in a string and a hash. Please note that variables in the message are wrapped with %{VAR} not ${VAR}.
# - The hash contains key value pairs with marker and the variable it will be assigned to.
# - The translate module passes it to fast_gettext's _() function. Primarily used for 'marking' a string to be added to a .pot file.
#
# @example
# fail(translate("Failure message"))
# @example
# fail(translate('message is %{color}'), {'color' => 'green'})
#
Puppet::Functions.create_function(:translate) do
# @param message Message to translate
# @param interpolation_values Optional.
# @return [String] translated message.
dispatch :translate do
param 'String', :message
optional_param 'Hash', :interpolation_values
end
def translate(message, interpolation_values = nil)
if interpolation_values.nil?
_(message)
else
# convert keys to symbols
interpolation_values = Hash[interpolation_values.map { |k, v| [k.to_sym, v] }]
_(message) % interpolation_values
end
end
