Add apt-repository, install ghc and cabal

I used this repository.

sudo add-apt-repository ppa:hvr/ghc
sudo apt-get install ghc-7.8.3
sudo apt-get install cabal-install-1.20

Add the bin directory to PATH

The packages install into /opt/ghc/$VER and /opt/cabal/$VER respectively. If you use zsh, make sure to add to bash settings as well. In Emacs haskell-mode, when hasekll-interactive-bring command tries to load ghci, the PATH envrionment seems to be under bash. Save the settings and test.

Issue

rails 4.1 production setting uses secret_key_base by reading values from the environment for security reason. If ENV["SECRET_KEY_BASE"] doesn't exist nginx + passenger will raise error. You can simply set up envrionment variable in the shell, but under rvm, it sometimes gets tricky.

Solution

Use figaro gem and set it up

• Gemfile, add gem 'figaro' and bundle update
• figaro install : this does
  • create config/application.yml
  • append .gitignore
• config/application.yml, add SECRET_KEY_BASE: your_key

At least from my experience and set up, this is not a proper way to make pry work under emacs 24.3 and current inf-ruby with MEPLA installation. Since this gist shows up quite high in google search result, I'd like to comment here what was the problem and how I solved it.

Issues

• (add-to-list 'inf-ruby-implementations '("pry" . "pry")) causes init.el load error. It's already implemented in the inf-ruby.el source so I don't think it's necessary to add again.

• (setq inf-ruby-default-implementation "pry") actually makes inf-ruby run the pry. However, with flaws. If pry is running with this set up and if I send the buffer/region/block, I get NameError: uninitialized constant IRB from (pry):1:in `__pry___'. Again, I looked into the inf-ruby.el source code and it looks like inf-ruby is already taking care of the pry smartly. So this set up shouldn't be added to init.el as well.

Solution

• don't add anything which is mentioned above to init.el to make pry work especially if it's in
