Byebug VS ruby

Just pry or with byebug? If the latter: https://github.com/deivid-rodriguez/byebug/issues/564

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.

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.

Immune from the compatibility issue with Zeitwerk

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.

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.

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.

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.

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.

Looking forward to this, byebug's Zeitwerk incompatibility is currently causing nondeterministic constant loading errors in our app when used with pry-byebug.

To create a new Rails app, you should have Ruby and Rails installed on your machine. You can find how to install Ruby on your local machine using the Ruby docs. You can install Rails by running the following command:

Ruby testing with RSpec

Not parent poster and do not have production YJIT experience. =)

My guess is that you would monitor `RubyVM::YJIT.runtime_stats[:code_region_size]` and/or `RubyVM::YJIT.runtime_stats[:code_gc_count]` so that you can get a feel for a reasonable value for your application, as well as know whether or not the "code GC" is running frequently.

Link to the commit

Part of the major userbase pull in GitHub revolves around hosting a considerable number of popular projects including Angular, React, Kubernetes, cpython, Ruby, tensorflow, and well even the software that powers this site Forem.

Hold option and click on the “collapse file” button in the Files view of a commit or pull request, and it will collapse all the files.

Select text in a comment, issue, or pull request description and press r—the selected text (including markdown formatting) will get pre-populated as a markdown block quote reply in the next comment box.

Add .patch or .diff to any pull request URL if you want to see a plain-text diff of the pull request (e.g. maybe you want to quickly `curl ... | git apply -` an unmerged pull request into a local copy of the repo without trying to add and fetch the git remote that the pull request is from).

There are lots of keyboard shortcuts. For example, / to jump to the file finder.

Not so much a secret but more like a hiding in plain sight: when looking at a commit GitHub will show you the earliest and latest tag (i.e. release) that includes the commit. For example, this commit[1] first appeared in v3_2_0_preview3.

The title is misleading, just like other commenters mentioned. Just check how much indirection "rb_iv_get()" has to make (at the end, it will call [1], which isn't "a light" call). Now, check generated JIT code (in a blog post) for the same action where JIT knows how to shave off unnecessary indirection.

We are comparing apples and oranges here.

I'm not sure why, but all the source values are listed here: https://github.com/ruby/ruby/blob/1cc700907d3ad3368272488a6f...

Maybe someone knowledgeable in the underpinnings of Ruby will explain why "class variable" was not hyphenated.
