Kint plugin for Craft CMS 3.x

Adds Kint, an in-app PHP debugger, to Craft CMS 3.x for use in Twig and PHP.

Requirements

This plugin requires Craft CMS 3.0 or later.

Installation

To install the plugin, follow these instructions.

1. Open your terminal and go to your Craft project:

    cd /path/to/project
   

2. Then tell Composer to load the plugin:

    composer require mildlygeeky/craft-kint
   

3. In the Control Panel, go to Settings → Plugins and click the “Install” button for Kint.

Kint Overview

Kint is an interactive debugger for PHP applications. Full documentation is available at https://github.com/kint-php/kint/.

Its advantages include that it can be run out of devMode (though you would not want to use it in a public setting), and it is interactive, with keyboard shortcuts to expand and collapse objects, separates content from methods, etc.

Configuring Kint

No configuration required, but you can set the theme that Kint will use within the plugin's settings screen.

Using Kint

• Click anywhere on the bar to unfold it
• Double click + to unfold all children
• Press d to toggle keyboard navigation.
• Press the “⇄” icon on the right to see what code you’d need to use to get at a piece of data.
• Press the “⌕” icon on the right to open a live search.
• Change tabs to see different views of data.
• You can sort tables of data by clicking on the headers.

Templating

d (dump)

{{ d(entry) }} or {{ d(entry, otherEntry) }}

This is the simplest usage, and will output an interactive debugger for the variable passed in.

j (dump - console.log())

{{ j(entry) }} or {{ j(entry, otherEntry) }}

This is the same as d, except all output will be sent to console.log()

s (simple dump)

{{ s(someTwigVariable) }} or {{ s(entry, otherEntry) }}

This works essentially the same way as the built-in Twig dump method, and returns a plain text debugging output.

microtime (point-in-time memory usage and timestamp)

{{ microtime() }} and {{ microtime(true) }} to reset the counter

Basic reporting of memory usage at the time that the command is run, as well as a timestamp. If used multiple times, it will also report the time since it was last called and average duration. Passing true as an argument will reset the counter.

trace (backtrace)

{{ trace() }}

Outputs a PHP backtrace from the point at which the function is called - note, this function uses quite a bit of memory (you should likely set memory_limit 512M, and the output might not be all that helpful, as you are mostly going to be seeing compiled PHP from the Twig templates.
