(upbeat music)…- [Instructor] It's time for a challenge assignment.…In this challenge, I want you to try and build…a list maker program.…It's going to be an interactive command line program…to allow users to manage a list that's saved in a file.…So, it's going to find the list file if it already exists…and if not, it's going to create a new file.…The user can view the current list…which means that you would need to read back the items…that are stored in the file.…The user can also add new items to the end of the list.…
And the user can edit any item in the list.…Now you won't have to create this from scratch.…In the exercise files I've given you some code…to start you out.…In the exercise files you'll find a folder called…list_maker.…If you take a look you'll see there's a init.rb file,…a lib file that has two classes in here that…we're going to work with.…So the first is init.rb.…It's pretty simple.…It has our shebang line at the top…and then it's going to figure out what the app root is.…Notice that I'm using expand path and dirname…
