Default task for namespace in Rake

Place it outside the namespace like this:

namespace :my_tasks do  task :foo do    do_something  end  task :bar do    do_something_else  endendtask :all => ["my_tasks:foo", "my_tasks:bar"]

Also... if your tasks require arguments then:

namespace :my_tasks do  task :foo, :arg1, :arg2 do |t, args|    do_something  end  task :bar, :arg1, :arg2  do |t, args|    do_something_else  endendtask :my_tasks, :arg1, :arg2 do |t, args|  Rake::Task["my_tasks:foo"].invoke( args.arg1, args.arg2 )  Rake::Task["my_tasks:bar"].invoke( args.arg1, args.arg2 )end

Notice how in the 2nd example you can call the task the same name as the namespace, ie 'my_tasks'

Not very intuitive, but you can have a namespace and a task that have the same name, and that effectively gives you what you want. For instance

namespace :my_task do  task :foo do    do_foo  end  task :bar do    do_bar  endendtask :my_task do  Rake::Task['my_task:foo'].invoke  Rake::Task['my_task:bar'].invokeend

Now you can run commands like,

rake my_task:foo

and

rake my_task

I suggest you to use this if you have lots of tasks in the namespace.

task :my_tasks do  Rake.application.in_namespace(:my_tasks){|namespace| namespace.tasks.each(&:invoke)}end

And then you can run all tasks in the namespace by:

rake my_tasks

With this, you don't need to worry to change your :all task when you add new tasks into that namespace.
