Coverity Scan vs RuboCop: What are the differences?
Coverity Scan: Find and fix defects in your Java, C/C++ or C# open source project for free. Coverity's implementation of static analysis can follow all the possible paths of execution through source code (including interprocedurally) and find defects and vulnerabilities caused by the conjunction of statements that are not errors independent of each other; 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.
Coverity Scan and RuboCop belong to "Code Review" category of the tech stack.
RuboCop is an open source tool with 10.1K GitHub stars and 2.14K GitHub forks. Here's a link to RuboCop's open source repository on GitHub.
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.
