Hi all,

I try to call a task of a namespace from an other task !

Exemple:

ReleaseDirectory = File.join( “d:”, “release” )

namespace :release do  
task :create do  
mkdir\_p ReleaseDirectory, QUIET  
end  
end

namespace :kernel do  
task :compile do  
end

```
task :release => [????] do
end

```

end

“???” What can I put ? I would like to use the task “:create” of the  
namespace “:release”. Is there a way to resolve my problem ?

Thanks

Stephane W.

Ok, I found a solution but I don’t know if it’s a good solution.

I put the namespace :release in a variable.

Example:

releaseNs = namespace :release do  
task :create do  
mkdir\_p ReleaseDirectory  
end  
end

namespace :kernel do  
task :compile do  
end

```
task :release => [releaseNs[:create] ] do
end

```

end

What do you think of this solution ?

Well, you’re not strictly “calling” the task. You’re making it a  
dependency.

a dependency.

Do you think that my previous mail is a good solution ?
