Wut

Wut is a faster, lazier, way to do puts debugging. With 3 characters, you can get a printout of your variable values. Great for debugging, or feeding into an LLM.

w.tf

• Dynamic Variable Inspection: View locals, instance variables, globals, class variables, and let variables with simple commands.
• Customizable Output: Automatically excludes ignored variables defined in an ignore list.
• Colorized Output: Enhanced readability with color-coded debug information.

Add Wut to your Gemfile:

bundle add wut

Or install it manually:

gem install wut

Wut enhances the binding object, allowing you to inspect variables with concise syntax: It also gives you a short alias--w for quick debugging.

• w.l - Print local variables.
• w.i - Print instance variables.
• w.c - Print class variables.
• w.g - Print global variables.
• w.tf - Print the full set of variables--locals, instance, class and lets.
• w.tf? - Print the full set of variables, plus globals too.

If you opt not to create the alias for binding, you can get the same methods from binding.

require 'wut'

class Example
  @@class_var = "class variable"

  def initialize
    @instance_var = "instance variable"
  end

  def debug_example
    local_var = "local variable"
    w.tf?  # Print all variables
    w.l  # Print only locals
  end
end

Example.new.debug_example

Output:

From: example.rb:13

Locals:
  local_var: "local variable"

Instances:
  @instance_var: "instance variable"

Class Vars:
  @@class_var: "class variable"

Globals:

Customize the variables excluded from output by adding them to the ignore list:

Wut.ignore_list << :@ignored_var

Automatically enable Wut by requiring it:

require 'wut'

After cloning the repository, set up the environment:
