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

Adding an item to Linux Mint Cinnamon Menu

Last time I took you through installing Sublime Text 2 on Linux Mint . The trouble with doing the install the manual way as I showed and not using sudo apt-get is that you don't get the neat integration into the operating system so you wont find Sublime Text in your Menu and if you search it wont be there yet. Right click on the "Menu" in the bottom left and choose "Edit Menu". You should have something that looks like this: Excellent. On my install, Programming was not yet ticked, so I clicked the checkbox so that the Programming section would show up in my Applications menu. Then on the left hand side, you need to click Programming, or whichever other category you want to put Sublime Text into and then on the right, click the "New Item" and fill it in as follows: If you followed along when I installed Sublime Text, you aliased subl to launch Sublime Text. Clicking where the icon is will let you choose the icon location. I used the 48x48 icon...

Getting started with Ruby on Rails 3.2 and MiniTest - a Tutorial

For fun, I thought I would start a new Ruby on Rails project and use MiniTest instead of Test::Unit. Why? Well MiniTest is Ruby 1.9s testing framework dejour, and I suspect we will see more and more new projects adopt it. It has a built in mocking framework and RSpec like contextual syntax. You can probably get away with fewer gems in your Gemfile because of that. Getting started is always the hardest part - let's jump in with a new rails project rails new tddforme --skip-test-unit Standard stuff. MiniTest sits nicely next to Test::Unit, so you can leave it in if you prefer. I've left it out just to keep things neat and tidy for now. Now we update the old Gemfile: group :development, :test do gem "minitest" end and of course, bundle it all up.....from the command line: $ bundle Note that if you start experiencing strange errors when we get in to the generators later on, make sure you read about rails not finding a JavaScript runtime . Fire up...

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...
