I believe gem open to be one of the least utilized commands to run by RoR developers. No need to browse the source code online. You can load it up in your favorite editor like so.

Here is the text if you want to copy and paste it:

# 1️⃣ If you want to open an installed gem

gem open actionview -e code

# ▶️ or if you have set in your terminal $EDITOR or $VISUAL gem open actionview

# ▶️ If you are inside a project that used Gemfile and has Gemfile.lock

bundle open actionview

# 2️⃣ If you did changes and want to restore gem to its cached version

gem pristine actionview

bundle pristine

bundle install --redownload # will redownload all bundled gems
