Debugging is a critical skill for Ruby developers, and the RubyMine team shares insights on effective debugging techniques in their blog. The post begins with a real-world example of a bug encountered in a Ruby project, illustrating how small syntax errors can lead to significant logical flaws. The example highlights the importance of understanding Ruby's operator precedence and the need for proper debugging techniques. The article discusses various debugging tools available to Ruby developers, starting with basic methods like using puts statements, which are simple but can clutter code. It then introduces interactive consoles such as IRB and Pry, which allow for more complex investigations without needing to restart the program. Finally, the post covers full-featured debuggers like byebug, debug, and the RubyMine debugger, which provide comprehensive control over program execution, enabling developers to set breakpoints, inspect variables, and step through code. Each tool has its strengths and weaknesses, and the choice often depends on the specific project requirements and personal preferences. The RubyMine team encourages developers to explore these tools and share their experiences, emphasizing that effective debugging is essential for writing reliable code.

I use nvim-dap with nvim-dap-ruby; it's excellent.
Every benefit the post ascribes to RM's debugger applies to nvim-dap (modulo the user's ability to do basic neovim customization), with the added points that:
- nvim-dap is protocol-based, so you can use the same configuration with many languages
- it's completely free
So I think of the debugger and the chess board as prosthetics that allow people who like me who are handicapped by a lack of brilliance to perform at a useful fraction of the truly talented.
Plus it's fun. The fast feedback and rapid iteration has the same kind of psychic reward as a good video game.
