Gem Home for Fish Shell

Robert James Kaes — Mon, 30 Apr 2018 15:58:06 -0400

In a recent twitch stream, Gary Bernhardt showed a bit of behind-the-scenes in how he prepares his development environment for recording a screencast.

One of the tools he showed in passing was gem_home by Hal Brodigan.

gem_home is a simple script that manipulates Ruby’s GEM_HOME and GEM_PATH environmental variables in order to keep separate ruby gem locations.

By using gem_home, there is no longer a requirement to prefix all ruby commands with bundle exec. All the gems for a project are local to the project, which eliminates conflicts that might arise when gems for multiple projects are mixed together in one location.

Eliminating the need for bundle exec allows commands such as rspec to execute much quicker!

Unfortunately for me, I recently switched over to using fish shell from ZSH. Hal’s gem_home only supports Bash and ZSH. 🙁

One nice thing about gem_home is how simple and straightforward it is. In a few hours I was able to replicate its functionality as a fish shell compatible script!

If you’re using ruby and fish shell, I would highly recommend using my implementation of gem_home along with Jean Mertz’s wrapper around chruby. Both of these play well together.

Enabling Vim Rails

Robert James Kaes — Wed, 17 Jan 2018 11:17:42 -0500

vim-rails is enabled only if config/environment.rb is present in the Rails working directory.

At work, we have an engine based working directory that does not contain this file (as there’s an embedded application within the engine.)

To enable vim-rails, I need to do:

echo "load ::File.expand_path('../../embedded-app/config/environment.rb',__FILE__)" >> config/environment.rb
mkdir -p .git/info
echo "config/environment.rb" >> .git/info/exclude

Within the repo to enable vim-rails support.

Checking for Cookie Deletion by a Rails Controller with RSpec

Robert James Kaes — Tue, 15 Apr 2014 12:00:00 +0000

Today I needed to prove that my Rails controller method deleted a cookie. After Googling for the answer (without success), I came up with the following.

Within your controller:

cookies.delete('cookie-to-delete')

In your controller spec you can check that the cookie was deleted with:

expect(response.cookies).to include('cookie-to-delete' => nil)

Rails sets the cookies to be deleted to a value of nil. By checking for the presence of both the cookie name with a value of nil, you can ensure your controller code deleted the cookie.
