开源软件名称:MakeSchool-17/ruby-koans-cmaher92开源软件地址:https://github.com/MakeSchool-17/ruby-koans-cmaher92开源编程语言:Ruby 100.0%开源软件介绍:¶ ↑Neo Ruby KoansThe Ruby Koans walk you along the path to enlightenment in order to learn Ruby. The goal is to learn the Ruby language, syntax, structure, and some common functions and libraries. We also teach you culture by basing the koans on tests. Testing is not just something we pay lip service to, but something we live. Testing is essential in your quest to learn and do great things in Ruby. ¶ ↑The StructureThe koans are broken out into areas by file, hashes are covered in Each koan builds up your knowledge of Ruby and builds upon itself. It will stop at the first place you need to correct. Some koans simply need to have the correct answer substituted for an incorrect one. Some, however, require you to supply your own answer. If you see the method ¶ ↑Installing RubyIf you do not have Ruby setup, please visit ruby-lang.org/en/downloads/ for operating specific instructions. In order to run the koans you need *nix platforms from any terminal window: [~] $ ruby --version [~] $ rake --version Windows from the command prompt ( c:\ruby --version c:\rake --version If you don't have Any response for Ruby with a version number greater than 1.8 is fine (should be around 1.8.6 or more). Any version of ¶ ↑Generating the KoansA fresh checkout will not include the koans, you will need to generate them. [ruby_koans] $ rake gen # generates the koans directory If you need to regenerate the koans, thus wiping your current `koans`, [ruby_koans] $ rake regen # regenerates the koans directory, wiping the original ¶ ↑The Path To EnlightenmentYou can run the tests through *nix platforms, from the [ruby_koans] $ rake # runs the default target :walk_the_path [ruby_koans] $ ruby path_to_enlightenment.rb # simply call the file directly Windows is the same thing c:\ruby_koans\rake # runs the default target :walk_the_path c:\ruby_koans\ruby path_to_enlightenment.rb # simply call the file directly ¶ ↑Red, Green, RefactorIn test-driven development the mantra has always been red, green, refactor. Write a failing test and run it (red), make the test pass (green), then look at the code and consider if you can make it any better (refactor). While walking the path to Ruby enlightenment you will need to run the koan and see it fail (red), make the test pass (green), then take a moment and reflect upon the test to see what it is teaching you and improve the code to better communicate its intent (refactor). The very first time you run the koans you will see the following output: [ ruby_koans ] $ rake (in /Users/person/dev/ruby_koans) /usr/bin/ruby1.8 path_to_enlightenment.rb AboutAsserts#test_assert_truth has damaged your karma. The Master says: You have not yet reached enlightenment. The answers you seek... <false> is not true. Please meditate on the following code: ./about_asserts.rb:10:in `test_assert_truth' path_to_enlightenment.rb:38:in `each_with_index' path_to_enlightenment.rb:38 mountains are merely mountains your path thus far [X_________________________________________________] 0/280 You have come to your first stage. Notice it is telling you where to look for the first solution: Please meditate on the following code: ./about_asserts.rb:10:in `test_assert_truth' path_to_enlightenment.rb:38:in `each_with_index' path_to_enlightenment.rb:38 Open the # We shall contemplate truth by testing reality, via asserts. def test_assert_truth assert false # This should be true end Change the In this case the goal is for you to see that if you pass a value to the ¶ ↑Running the Koans automaticallyThis section is optional. Normally the path to enlightenment looks like this: cd ruby_koans rake # edit rake # edit rake # etc If you prefer, you can keep the koans running in the background so that after you make a change in your editor, the koans will immediately run again. This will hopefully keep your focus on learning Ruby instead of on the command line. Install the Ruby gem (library) called cd ruby_koans rake # decide to run rake automatically from now on as you edit gem install watchr watchr ./koans/koans.watchr ¶ ↑InspirationA special thanks to Mike Clark and Ara Howard for inspiring this project. Mike Clark wrote an excellent blog post about learning Ruby through unit testing. This sparked an idea that has taken a bit to solidify, that of bringing new rubyists into the community through testing. Ara Howard then gave us the idea for the Koans in his ruby quiz entry on Meta Koans (a must for any rubyist wanting to improve their skills). Also, “The Little Lisper” taught us all the value of the short questions/simple answers style of learning.
