rakefile

I want to run a ruby class from a sample.rake file. Consider myruby.rb is a ruby file. I want to run this from sample.rake like ruby myruby.rb Adding to what @tobias has to say here you go with an example script sample content of myruby.rb puts "hello world" Create file called Rakefile task :default => [:test] task :test do ruby "my_file.rb" end Now if you invoke rake it should file up hello world text in console. Update It would make more sense if you wrap your call in a function call as suggested already by @tobias So your Rakefile would become something like require './myruby.rb' task

Part of my seeds.rb loads a lot of data into the database. I want to be able to selectively load this data. E.g. $ rake db:seed or $rake db:seed[0] would just load the necessary data to run the site, while $ rake db:seed[1] would load my big data file into the database as well. Is this possible? How can I make this happen? If not, can anyone think of a way to do what I'm trying to do? Rake arguments are painful to pass around, unfortunately (and db:seed doesn't pass its arguments through, regardless). Your best bet is to use environment variables to pass your extra args through: rake db:seed

I am trying to get a .rb file to make another .rb file within a specific directory with specified content, when that file is run. I dont know whether the best way to do this would be with a Ruby file or a Rake file. You input would be great. If you just need to perform a simple script like creating a file, you can simply use a Ruby script without creating a rake task. # file origin.rb target = "target.rb" content = <<-RUBY puts "I'm the target!" RUBY File.open(target, "w+") do |f| f.write(content) end And you can execute the file with $ ruby origin.rb directory = "../../directory" File.open

I have started learning Ruby and just tried out my first hello world program in NetBeans IDE. I have one doubt, I can see that the new project wizard created set of package structure. It had one "Rakefile" in it. What does that mean and what is the use of it? It is an alternative to Makefile with Ruby syntax.
