  • Interactive Ruby (IRB) (2023)
    1 project | news.ycombinator.com | 27 Mar 2024
    I think one of the most interesting things to happen to IRB is the recent introduction of static type completion[1].

    The fact that this is a nice, mainstream, usage of RBS types in the standard library gives me hope that RBS or some kind of inline[2] version of it will become much more common in future.

    1. https://github.com/ruby/irb?tab=readme-ov-file#type-based-co...

    2. The new Prism parser makes it much easier to extract an execute comments so I would be surprised if no one has thought of using that to annotate code with RBS types.

  • IRB's Built-In Measure
    1 project | news.ycombinator.com | 9 Apr 2023
    Starting in ruby 2.6, irb is a gem bundled with ruby, so you can upgrade to the latest version in older rubies: https://github.com/ruby/irb#installation
  • Readline is busted for me so I wrote my own REPL
    1 project | /r/ruby | 10 Mar 2022
    irb is now a bundled gem, so you can update it without having to update the whole ruby or install RVM. gem update irb
  • Q: suggestions in irb/rails console, where are they coming from?
    3 projects | /r/ruby | 12 Jan 2022
    I guess it's just not very well refined yes. Best might be to lock it to gem "irb", "< 1.4" in your Gemfile for the time being, and maybe report your feedback to https://github.com/ruby/irb
  • Ruby Underscore

    Yet it does not work exactly the way you might expect in IRB, because it’s explicitly configured to return the last used value in the Ruby console

  • Why does pry/Zeitwerk have issues loading constants in breakpoint context?
    2 projects | /r/rails | 1 May 2023
    Just pry or with byebug? If the latter: https://github.com/deivid-rodriguez/byebug/issues/564
  • How can you debug Rspec tests with VSCode?
    1 project | /r/ruby | 20 Apr 2023
    Byebug is not fully compatible with Zeitwerk, I was getting random NameError exceptions failing to load constants in development and tests until I removed this gem.
  • Improve Code in Your Ruby Application with RubyCritic
    7 projects | dev.to | 26 Oct 2022
    byebug - this elevates debugging Ruby applications. It allows you to run a program line by line, add breakpoints, and evaluate and track values at runtime. If you still use puts for debugging, it's time you get to know Byebug's features and commands.

  • Ruby on Rails(ROR) development environment setup(Mac OS)

    For debugging purposes, I recommend a few gems that will get you started and allow you to play with ruby code in your terminal and manage ruby gems. Gems like bundler pry and byebug do it good and you can check out the official docs, Pry, Byebug, Bundler, These gems need to be accessed globally.
  • Bust Bugs with the Byebug Bug Debugger
    1 project | dev.to | 17 Mar 2022
    Byebug is a helpful and easy-to-use debugger made for Ruby. It allows developers to use traditional debugging features to help identify what is happening in a program while it's running. Byebug was created by David Rodriguez in hopes of building a better Ruby debugger.
  • What gem is used with conjunction with "pry" for step by step debugging?
    4 projects | /r/ruby | 20 Jan 2022
    Others have been suggesting byebug, but for us it started causing random constant loading errors on Ruby 3 in Rails, due to Zeitwerk compatibility issues. So I'm quite happy that the debug gem came in as a replacement. I did like that pry-byebug allows stepping in a normal Pry console, I expect the debug gem will require some getting used to.
  • Some Helpful Ruby Gems
    3 projects | dev.to | 7 Jan 2022
    As far as debugging tools go, the Byebug and Pry are two of the best gems I have found. They are used in different contexts, but for all intents and purposes, including them in your code will halt an operation and allow you to access whatever point in the code you halted within your terminal with a REPL.
  • Rails 7 introduces a new debugging gem
    3 projects | dev.to | 12 Nov 2021
    We commonly use byebug for debugging our code which is an easy-to-use, feature-rich ruby debugger. This gem is introduced in Rails 5. It offers features like Stepping, Breaking, Evaluating and Tracking.
  • Rails 7 replaced byebug with ruby/debug
    2 projects | /r/ruby | 29 Sep 2021
    Looking forward to this, byebug's Zeitwerk incompatibility is currently causing nondeterministic constant loading errors in our app when used with pry-byebug.
