Super useful CLI utility to count lines of code of basically any language 👌 It can also output results in other formats like JSON, CSV or YAML.

Middleman is underrated. It's still one of the best frameworks to build static sites. It works nice for simple websites, for blogs, and due to some of its features (data + proxy + config as code), you can also build more sophisticated static web-apps.

Very useful gem to run distributed "cron" tasks over Redis. It works with minimal setup, you just need to define a YAML with your tasks and their scheduling time (that can be defined in natural language: "every 6 hours").

Rubocop is probably the de facto linter and static code analyzer for Ruby. It comes with some "sensible" defaults, but it's really really flexible, so your team can easily customize your preferences. The hardest part is to align those preferences :) That's why probably Standard Ruby exists.

The best framework to build CLI applications in Ruby. It has a "core" package and then each component/feature (colors, prompts, tables, ...) is distributed as a different gem, so you install only what you need.

Amazing tool.
