ruby - Rails Gem: Running All Generators for given Namespace -

i'm developing gem core multiple sub modules, each it's own gem. developer, you'll able install core , other of gems. how can create rake task or generator run generators of installed gems generators under main gem namespace.

example, if gem called admin:

module admin   module generators     class installgenerator < rails::generators::base     end   end end 

and have generator 1 of sub-gems:

module admin   module generators     class postsgenerator < rails::generators::base     end   end end 

and one:

module admin   module generators     class tagslgenerator < rails::generators::base     end   end end 

and there might 10 more gems can installed. rather rail g admin:... installing each one, create rake task or generator runs of tasks.

thanks in advance!

keep "allgenerator" class under admin module. generator have following :

1. for each class under namespace generator class,
2. get namespace classname.
3. call invoke method namespace.

something :

module admin   module generators     class allgenerator < rails::generators::base       def generator         rails::generators.lookup!         admin::generators.constants.each |const|           generator_class = admin::generators.const_get(const)           next if self.class == generator_class           if generator_class < rails::generators::base             namespace = generator_klass_to_namespace(generator_class)             invoke(namespace)           end         end       end       private         def generator_klass_to_namespace(klass)           namespace = thor::util.namespace_from_thor_class(klass)           return namespace.sub(/_generator$/, '').sub(/:generators:/, ':')         end     end    end end 

here's link gist complete tested code

this way, running rails g admin:all run every other generator directly under admin::generators .
