Added deploy:set_rails_env to run after invoking stage

[sponomarev]

Hello!

What about setting RAILS_ENV before all tasks after invoking stage?

Capistrano::DSL.stages.each do |stage|
  after stage, 'deploy:set_rails_env'
end

It'l be useful in other gems using RAILS_ENV for transparent support, ex. capistrano3-rails etc.

Nice idea!
Are you sure that in task :normalize_assets => [:set_rails_env] :set_rails_envwon't be executed twice?

Yes, i am. Rake dependencies run only once. Simple example can prove it.

namespace :my_test do
  desc 'Dependency'
  task :dependency do
    puts 'This is very important dependency'
  end

  desc 'Task1'
  task :task1 => :dependency do
    puts 'This is task 1'
  end

  desc 'Task2'
  task :task2 => :dependency do
    puts 'This is task 2'
  end

  desc 'Run all tasks'
  task :all => [:task1, :task2]
end

dependency task runs only once as you see.

toad@taunton:~/Projects/SaltPepper/snp-testapp $ rake my_test:all --trace
** Invoke my_test:all (first_time)
** Invoke my_test:task1 (first_time)
** Invoke my_test:dependency (first_time)
** Execute my_test:dependency
This is very important dependency
** Execute my_test:task1
This is task 1
** Invoke my_test:task2 (first_time)
** Invoke my_test:dependency
** Execute my_test:task2
This is task 2
** Execute my_test:all

capistrano:deploy's trace also proves it, but it's log is so looooong 😄
