Hi,

Is it possible to make the default task the same as using the -T  
option? I.e. I want to type:

% rake

And see all the tasks.

Thanks, James. Turns out that doesn’t work so well. But your suggestion  
spark an  
idea and I and figured out a way:

task :default =\> [:tasks]

task :tasks do  
Rake.application.display\_tasks\_and\_comments  
end

I assume you could make a task that shells out to rake -T.

This doesn’t work for me, viz,

$ rake  
(in /Users/kleb)  
$

Apparently, with rake 0.7.1 you also need to set the regexp filtering  
the tasks:

task :tasks do  
Rake.application.options.show\_task\_pattern = //  
Rake.application.display\_tasks\_and\_comments  
end

Ciao
