Better format for byebug (with colors)

Question

Is there a way to get a better format of output with byebug? When I print objects the output is a little hard to read, would be better with colors similar to Awesome Print.

Use your pp. Try `require "pp"` and when inspecting objects use `pp object`. — DiegoSalazar, Dec 02 '15 at 00:01
Pry has been super helpful, but that's more about line formatting than color. — Lanny Bose, Dec 02 '15 at 08:13

There is no native option on byebug to format the output with colors, but there is a Gem you can use to colorize some of byebug output for ease of readability, which I think is what you are aiming here.

Please follow this link to see instructions on how to install byebug-color-printer Gem. https://github.com/ahmadsherif/byebug-color-printer

Or you could use pry. https://github.com/pry/pry :)

Let me know how this works for you. I hope it helps.

byebug-color-printer won't work unless you want to use a very old version of byebug: https://github.com/ahmadsherif/byebug-color-printer/blob/master/byebug-color-printer.gemspec#L21 – Gerry Aug 27 '16 at 07:30

I am using a hack for byebug syntax highlighting from this gist for more than a year now.

It is not perfect, but it does its job well.

Here is an example:

Note: It works for byebug v10.0.0 and higher.

What's the not perfect thing about it? – picheto Apr 22 '22 at 16:10

If you add awesome_print to your project (via the Gemfile if you use bundler), then ap will be available to you inside byebug.

debug.rb (aka binding.break)

Consider using a new Ruby debugging tool called debug.rb.

It supports syntax highlighting and many more out-of-the-box.

Also, it is worth mentioning that it is developed by the Ruby core team.

Just place binding.break anywhere in your codebase.

Here is an example:

Also, it is a default Rails debugger starting from version 7.

Notes:

Do not forget about require 'debug'
q # quit command
