Installing RVM on Linux Mint 13

Linux Mint has captured my imagination recently, and of course a fresh install means getting my dev environment up and running again. I'm using the cinnamon version and so far things are going well. Everything on my laptop is just working; suspend, all the various function keys. Support out of the box is good. I'm impressed. The experience is soooo much better than the last time I tried a more full featured distro and things got so bad with video drivers crashing and causing my fan to spin up constantly that I ended up going totally minimal with Arch and just a command line. I like arch, but I thought I would give Mint a go. So, now we need to get Ruby, RVM and Rails on the go so we can do some web development. Let's start with RVM. Next time I'll take a crack at installing Rails on Mint First things first - we need curl. My install didn't have it so.....fire up the terminal with Ctrl-Alt-T and type the following
sudo apt-get install curl
Next up, install RVM
curl -L https://get.rvm.io | bash -s stable --ruby 
Which all went pretty well. At the end of the install, simply running
source ~/.rvm/scripts/rvm 
in my open terminal session brought everything up to snuff. Now I'm going to install a few dependencies
rvm requirements 
to check what you need on your system. Mine needed the following command to get up to speed.
sudo apt-get install build-essential openssl libreadline6 libreadline6-dev \
curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 \
libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison  \
subversion
And annoyingly I had to
rvm reinstall 1.9.3
because it was already installed but without doing the reinstall all sorts of nasty errors would occur when trying to install gems later on. Next a quick verification:
which ruby
>> /home/rubyflewtoo/.rvm/bin/ruby

ruby -v
>>ruby 1.9.3p194
I didn't have a system ruby installed given my version of Linux Mint was fresh off the boat, but if you did and you want to default to ruby 1.9.3 (which you should) then you could run
rvm use 1.9.3 --default

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

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
