rake --tasks full description (not cut)

Question

Maybe it's one of those code 18,

but when I run rake -T on my Rakefile, the long descriptions of my tasks are always cut. Is there any way to display the full description without having to make the desc shorter?

Thanks

Answer 1

The format is slightly different (description starts on the next line instead of as a comment on the current line), but this will give you the full descriptions:

rake -D

Also, if you really want the other format, you can pipe the output to cat instead:

rake -T | cat

Answer 2

-D, --describe [PATTERN] Describe the tasks (matching optional PATTERN), then exit.

rake -D

Answer 3

Three solutions:

1) You may define your own '-T'

task :longT do
  app = Rake.application
  app.tasks.each{|task|
    puts "%-20s  # %s" % [task.name, task.comment] if task.comment
  }
end

2) fool, there is no tty:

Rake.application.tty_output= false    

3) Modify a rake command

module Rake
  class Application
    def truncate_output?
      #tty_output? || ENV['RAKE_COLUMNS']
      false
    end
  end
end

I would recommend version 2)

(Tested with rake-0.8.7)

Answer 4

There's an environment variable you can set:

export RAKE_COLUMNS=200
