Credo vs RuboCop: What are the differences?
Credo: A static code analysis tool for the Elixir language. credo can show you refactoring opportunities in your code, complex and duplicated code fragments, warn you about common mistakes, show inconsistencies in your naming scheme and - if needed - help you enforce a desired coding style; RuboCop: A Ruby static code analyzer, based on the community Ruby style guide. RuboCop is a Ruby static code analyzer. Out of the box it will enforce many of the guidelines outlined in the community Ruby Style Guide.
Credo and RuboCop belong to "Code Review" category of the tech stack.
Credo and RuboCop are both open source tools. It seems that RuboCop with 10.1K GitHub stars and 2.14K forks on GitHub has more adoption than Credo with 2.96K GitHub stars and 215 GitHub forks.
To communicate isn’t just getting rid of syntax errors and making code work. The code should communicate ideas to people through a programming language that computers can also understand.
You should adopt semantic variables, classes, modules, and methods names. For instance, in Ruby, we avoid using particular prefixes such as is_paid, get_name and set_name. In their places, we use directly paid?, name, and name=.
My advice is to use idiomatic and features that the programming language you use offers to you whenever possible, and figure out ways to better pass the message.
Why wouldn’t we be worried about semantics, typos, and styles? We should care for the quality of our code, and the many concepts that define it. You can start by using a linter to collect some issues from your codebase automatically.
