Jekyll and ruby 1.9.3 site not regenerating

If you are trying to compile a site with Jekyll and ruby 1.9.3 and you have some dodgy yaml front matter in one of your posts, your site just won't regenerate. Step 1 is to edit your _config.yaml and set auto: false. If you leave auto:true then it won't report the errors at all. With that, if you run your jekyll --server command again, you could get an error to the effect of "did not find expected key while parsing a block mapping at line" blah blah blah. The error isn't particularly useful. However, help is at hand - see this pull request which you can manually apply to your gem if you want and you'll start to get meaningful error messages again. I monkey patched mine by editing my lib/jekyll/post.rb file to include the pull request's code. I guess you could use RVM and use an older ruby version, but this did the job for me

Rails 3.2, MiniTest Spec and Capybara

What do you do when you love your spec testing with Capybara but you want to veer off the beaten path of Rspec and forge ahead into MiniTest waters? Follow along, and you'll have not one, but two working solutions. The setup Quickly now, let's throw together an app to test this out. I'm on rails 3.2.9. $ rails new minicap Edit the Gemfile to include a test and development block group :development, :test do gem 'capybara' gem 'database_cleaner' end Note the inclusion of database_cleaner as per the capybara documentation And bundle: $ bundle We will, of course, need something to test against, so for the sake of it, lets throw together a scaffold, migrate our database and prepare our test database all in one big lump. If you are unclear on any of this, go read the guides . $ rails g scaffold Book name:string author:string $ rake db:migrate $ rake db:test:prepare Make it minitest To make rails use minitest , we simply add a require ...

Getting started with Docker

Docker, in the beginning, can be overwhelming. Tutorials often focus on creating a complex interaction between Dockerfiles, docker-compose, entrypoint scripts and networking. It can take hours to bring up a simple Rails application in Docker and I found that put me off the first few times I tried to play with it. I think a rapid feedback loop is essential for playing with a piece of technology. If you've never used Docker before, then this is the perfect post for you. I'll start you off on your docker journey and with a few simple commands, you'll be in a Docker container, running ruby interactively. You'll need to install Docker. On a Mac, I prefer to install Docker Desktop through homebrew: brew cask install docker If you're running Linux or Windows, read the official docs for install instructions. On your Mac, you should now have a Docker icon in your menu bar. Click on it and make sure it says "Docker desktop is running". Now open a terminal and ty...

Poor person's guide to managing Ruby versions

Understanding the guts of Ruby Version Management by rolling your own I've been tinkering with a fresh install of Ubuntu 12.10, setting up a nice clean development environment. One of the first things to do, of course, is implement some sort of Ruby version management. RVM and rbenv seem to be the clear winners in this arena, though there are a lot of tools out there that do a similar job . Writing your own version management for your Rubies isn't actually all that difficult. At it's core, we need need two things: A way to segregate the executables of the various versions A way to call the versions at will Segregating versions is trivial - working with files and folders, we can put the various versions into named directories. Actually executing our different versions is not all that difficult either. One way would be to create aliases with version numbers and explicitly call those when we want to use them. The more popular way, however, is to manipulate our PATH ...
