Features

• dd <variable> at any app/ place. Inspired by dd function from Laravel.

• wp <variable> at any app/ place. Inspired by classic PHP 'print' debug. It works for HTML pages and bypass other content types like application/json.

• dump <variable> at your views. It's alternative for debug method from ActionView::Helpers::DebugHelper and ap from AwesomePrint.

Installation

Add this line to your Gemfile:

gem 'debug-extras', group: :development

And then execute:

$ bundle

Usage

#dd

Call dd from any app/ place:

dd @books

#wp

Call wp from any app/ place:

wp 'Authors through #wp method (called from controller):'
wp @authors

#dump

Call dump from views:

<%= dump 'Books through #dump method (called from view):' %>
<%= dump @books %>

Styling

DebugExtras inject default CSS to the page on methods call. You can override styles and set your fonts, margins, etc using .debug-extras wrapper. Just look to the page sources to see them at the end of head section.

Example how to override default fonts in your stylesheet:

.debug-extras pre,
.debug-extras kbd {
    font-family: Consolas, SFMono-Regular, Menlo, Monaco, Ubuntu, monospace !important;
    font-size: 14px !important;
    line-height: 18px !important;
}

or may be you want to use pre-wrap rendering:

.debug-extras pre {
    white-space: pre-wrap !important;
}

Note: if #wp and #dump results look different compare to the screenshots above then default styles were overridden by yours.
