is there a way to “explicitly” invoke a block inside the scope of a
parent or explicit “root relative” rake namespace instead of always
being a child of the current namespace ???
namespace :xxx do
namespace :yyy do
namespace …
... called_in_unknown_namespace(arg);
end
end
end
def called_in_unknown_namespace(arg)
execute below block as if it were in “root” namespace
namespace ‘root namespace’ do
# declare additional item to do in root namespace task
task :task_in_root do
puts('invoked by "rake task_in_root"');
end
end
scope restored to wherever you were previously
end
Thanks!

Ok - figured it out looking at the source, since all tasks simply have
the “scope name” prepended to their name, and the “namespace” is just a
list of names that defines the currnet scope scope in the task manager,
then I was able to do the below to explicitly selct the “global scope”.
building the list from a scope name ie: ‘:name1:name2:name3’, ‘^name’
using the same format as a task name reference will make it general.
BTW what would be appropriate to specify an “absolute path” in rake
convention ??? since namespace :xxx specifies a relative child - ie:
desirably somethign like file paths ‘/’ and ‘…’ maybe ‘::’ ???
module Rake
module TaskManager
def in_explicit_namespace(name)
oldscope = @scope;
@scope = Array.new();
# build scope name list from name here
ns = NameSpace.new(self,@scope);
yield(ns)
ns
ensure
@scope = oldscope;
end
end
end
down below in a rakefile
namespace :num1 do
namespace :num2 do
Rake.application.in_explicit_namespace ‘:’ do
puts(“in explicit block”);
task :x do |t|
puts(" doing explicit task x");
end
end
end
end
from command line
$ rake x
doing explicit task x
$
