How to run Rake tasks from within Rake tasks?

🎉📝 How to run Rake tasks from within Rake tasks 🔄

Are you struggling to figure out how to run Rake tasks from within other Rake tasks? 🤔 Don't worry, you're not alone! It's a common challenge for many developers. But fear not, because in this blog post, we're going to tackle this issue head-on and provide you with some easy solutions.

Let's start by understanding the problem. You have a Rakefile that compiles your project in two different ways, based on the value of the global variable $build_type. You want to create a task that compiles the project with both configurations in turn. However, you're unsure how to call the :build task from within the :build_all task.

One way to achieve this is by utilizing the Rake::Task class and its invoke method. The invoke method allows you to call a task programmatically. 👩‍💻 Here's an example using your code snippet:

task :build_all do
  [:debug, :release].each do |t|
    $build_type = t
    Rake::Task["build"].invoke
  end
end

In this example, we iterate over the [:debug, :release] array and set the $build_type variable to the current iteration value. Then, we use the invoke method to call the :build task. This way, the :build task will be executed with the appropriate configuration.

But what if the :build task has dependencies? 😮 Don't worry, we've got you covered there too! You can use the invoke_with_dependencies method instead of invoke. This method ensures that all the dependencies of the task are also invoked. So even if the :build task depends on other tasks, they will be executed in the correct order. 🌟

task :build_all do
  [:debug, :release].each do |t|
    $build_type = t
    Rake::Task["build"].invoke_with_dependencies
  end
end

And there you have it! With just a few lines of code, you can now run Rake tasks from within other Rake tasks. 🎉

Now it's your turn! Give it a try in your own project and see how it works for you. If you have any questions or run into any issues along the way, feel free to leave a comment below. We're here to help! 💪
