Method needed to get rake command line options for spawning new rake job

I am implementing a "top level" Rakefile that will spawn off rake jobs in sub-directories.
This is not hard to do, except that I want to pass the same options to the jobs that was passed to the original rake command. I cannot find a way to reliably find out what those options were without using some quasi private methods such as handle_options in the application object. I do not want the targets, just the options.

Could we add code to handle_options to put the options that are parsed into an array that is a public attribute of the application object?

Then I could grab the rake options by a simple use of something like:

Rake.application.rake_options

If there is some way to easily do this that I am missing please let me know. I originally was just iterating over the ARGV entries and grabbing things out of it, but quickly realized that the command line options may or may not have an argument following a "-" prefixed option and there is no way I can know that without duplicating all the code in standard_rake_options.

Thanks.

Inizia da Rake.application e segui i punti di ingresso handle_options e standard_rake_options per vedere come vengono analizzate e mantenute le opzioni della riga di comando. Verifica come un Rakefile di primo livello potrebbe leggere il valore analizzato quando avvia job nelle sottodirectory. Il lavoro è completato quando le opzioni analizzate sono esposte tramite un attributo pubblico application senza richiedere ai chiamanti di duplicare l'analisi delle opzioni.
