Rake before task hook

Question

Is there a straight forward way to modify a Rake task to run some bit of code before running the existing task? I\'m looking for something equivalent to enhance, that runs

Answer 1

You can use the dependency of Rake task to do that, and the fact that Rake allows you to redefine existing task.

Rakefile

task :your_task do
  puts 'your_task'
end
task :before do
  puts "before"
end
task :your_task => :before

As result

$ rake your_task
before
your_task

Answer 2

Or you could use the rake-hooks gem to do before and after hooks:

namespace :greetings do 
    task :hola    do puts "Hola!" end ;
    task :bonjour do puts "Bonjour!" end ;
    task :gday    do puts "G'day!" end ;  
end 

before "greetings:hola", "greetings:bonjour", "greetings:gday" do
  puts "Hello!"
end

rake greetings:hola # => "Hello! Hola!"
