This is a collection of exercises to practice various aspects of Ruby.
Practicing in this manner (small, bite-sized problems that you can do repeatedly) is a fantastic way to solidify programming concepts.
Each folder in this repository is a set of related exercises. Open up the folder and read the README to learn more about them.
Structure of this repository
- Each folder contains a
README.mdfile that provides a summary of what skills you will develop with these exercises
- Each exercise file within the folder will begin with comments providing more detail on:
- How you need to manipulate or work with this file to complete the exercise.
- Some exercises will require you to manipulate the "current" file and run it. Other exercises will require you to create new files and then reference those files for the "current" file to work.
1. Clone this repository
You don't need to fork this repository; clone it to your laptop
/turing directory on your laptop (or whatever directory you want this repository to live inside of), run:
// using ssh keys git clone email@example.com:turingschool/ruby-exercises.git // using https, if the above doesn't work: git clone https://github.com/turingschool/ruby-exercises.git
Once this command runs, you'll now have a "local" copy of this entire repository, living right on your laptop.
2. From the command line,
cd into the
gem install bundler in your terminal
3. From the command line, run
You should see something like this:
$ bundle install Fetching gem metadata from https://rubygems.org/........ Resolving dependencies... Using bundler 2.1.4 Using byebug 11.1.3 Fetching coderay 1.1.2 Installing coderay 1.1.2 Using diff-lcs 1.4.4 Using method_source 1.0.0 Using pry 0.13.1 Fetching pry-byebug 3.9.0 Installing pry-byebug 3.9.0 Fetching rspec-support 3.10.1 Installing rspec-support 3.10.1 Fetching rspec-core 3.10.1 Installing rspec-core 3.10.1 Fetching rspec-expectations 3.10.1 Installing rspec-expectations 3.10.1 Fetching rspec-mocks 3.10.1 Installing rspec-mocks 3.10.1 Fetching rspec 3.10.0 Installing rspec 3.10.0 Bundle complete! 3 Gemfile dependencies, 12 gems now installed. Use `bundle info [gemname]` to see where a bundled gem is installed.
If you see that, great!
If you get an error like:
zsh: command not found: bundle
you need to install the
bundler gem. Run:
$ gem install bundler
If this command throws an error, you either:
- Don't have
- You've not yet installed a version of Ruby.
Hey, hold up. What is this
bundlething, and what does it do? what does
gem install bundlerdo?
bundler is Ruby's package manager. If you want to install extra code that works with Ruby, you'll use
bundler to do it. Once you have the
bundler installed, it is "used" by typing
bundle into your terminal.
It is used in conjunction with the
Gemfile.lock files you see in this repository, to manage Ruby gems.
Here's an exhaustive amount of information about gems, if you're so inclined: guides.rubygems.org/what-is-a-gem
bundle has run successfully, open up the first test!
$ cd data-types/strings $ atom .
