#gems_gem_home ⇒ String

def gems_gem_home
    File.join(gems_install_path, self.class.gems_path_suffix)
end












#gems_install_path ⇒ String







The gem install root into which the workspace gems are installed


Note that while this setting is separated from the other gems path, the only way to reliably isolate the gems of an autoproj workspace is to separate both the autoproj gems and the workspace gems. This is why there are only –public and –private settings in autoproj_install


The gems are actually installed under a platform and version-specific subdirectory (returned by #gems_path_suffix)








Parameters:


    

  • 
ws
(Workspace)
—

    

    the workspace whose gems are being considered
