Peek under the hood with sixty debugging reports just one click away.

== Description ==

For admins, developers, and support staff, **Debug This** provides a ton of information about your WordPress installation, all from the front-end admin bar.

* *The current WP_Query object*
* Blog info and options
* Embed providers
* Files in rendered HTML (CSS, images, JavaScript)
* Filters and actions
* Images sizes
* Globals and constants
* Menus
* Object cache stats
* Plugins, must-use plugins, and dropins
* Rewrite rules
* Queries
* PHP and server information
* Post attachments
* Post types
* Scripts and styles enqueued
* Shortcodes
* Sidebars and widgets
* Taxonomies and terms
* Themes
* Users
* WP cron schedules and jobs
* WP debug log

**Debug This** helps you save time and effort when trying to figure out what's going on. Instead of hardcoding debug snippets or writing complex unit
tests for small functionality, you can simply bring to the surface what you need right from the admin bar.

For example, when viewing a single post, you can see:

* a list of post attachments,
* which menus and sidebars are being displayed,
* the post type, post fields, and meta data,
* the current query variables and query string,
* the rewrite rules applied,
* the author,
* the terms,
* and much more.

== Installation ==

1. Upload to your plugins folder, usually `wp-content/plugins/`
2. Activate the plugin on the plugin screen.
3. Navigate to the front-end of your website and hover over the 'Debug This' menu item in the admin bar.

== Frequently Asked Questions ==

**How do I use Debug This?**

1. Make sure the admin bar is enabled in your user profile.
2. Visit any page/post/archive on your website and you will see a Debug This menu item on the admin bar.

**What PHP version is this compatible with?**

We've tested on PHP >= 5.2.17

**Can I request new debug modes?**

Certainly! In order to keep the plugin lightweight and performant, requests that are too localized for the greater good may be refused. If that happens, I will gladly help you build your own debug mode.

**Can I alter the plugin or build my own debug modes?**

Yes! Visit the [Extend section](https://wordpress.org/plugins/debug-this/other_notes/) to find out how you can thoroughly extend Debug This for your own needs.

== Screenshots ==

1. The current query, for example.
2. Enhanced display when a Kint debugger plugin is installed (see Description).

= Debug This Functions =

New debug modes can be created easily:

`
add_debug_extension(
	$mode,
	$menu_label,
	$description,
	$callback,
	$group = 'General'
);
`

**Example**

`
add_debug_extension(
	'actions',
	__('Actions', 'debug-this'),
	__('$wp_actions contains all active registered actions', 'debug-this'),
	'foo_callback',
	'Filters And Actions'
);
function foo_callback($buffer, $template){
	global $wp_actions;
	$debug = print_r($wp_actions, true);
	return $debug;
}
`

You can add links to the header of a debug mode page. Place this code within your debug callback function.

`add_debug_header_link('http://urltolink', 'Link Label');`


Extensions can be removed as well using `remove_debug_extension($mode);`


**No PRE Tags**

If you don't want your debug output to be enclosed in PRE tags, simply set the following in your extension:

`Debug_This::$no_pre = true;`

**Saved Queries and Execution Time**

Retrieve saved queries and execution time by using the following static properties:

* `Debug_This::$execution_time`
* `Debug_This::$queries` - SAVEQUERIES must defined as true

**URL Helpers**

* `Debug_This::get_current_debug_url()` - current URL with the debug query
* `Debug_This::get_escape_url()` - used for the debug escape link that links to original page URL

= WP Actions =

* `debug_this` - receives the $mode arg - outputs the debug code sent from the extension modes. The default action is set to priority 5. This allows you to prepend or append any output without conflict using less or greater priorities.

= WP Filters =

There are a few filters you can use to customize Debug This to your needs:

* `debug_this_template` - receives $template arg - Use your own template
* `debug_this_default_mode`  - receives $mode arg - Alters the mode for the parent DT admin bar button link.
* `debug_this_output` - receives $output, $mode args - Filter debug content before it's rendered

= JavaScript =

To access the built-in Debug This JS functionality, enqueue your custom script with the dependency set to `debug-this`. Your script will inherit a jQuery dependency.

**Object: debugThis**

* `debugThis.mode` - current mode
* `debugThis.defaultMode`
* `debugThis.template` - current included template
* `debugThis.queryVar` - the defined query string variable

**Functions:**

* `isDebug()`
* `getDebugMode()` - uses `isDebug()`

**Events:**

A jQuery `debug-this` event is fired from the footer. You can hook into this event with the following;
`
jQuery(document).bind('debug-this', function(event, debugThis){
	console.log(debugThis);
});
`

= Helper Functions =

There are three included functions to help you work with files.

* `debug_this_get_file_ownership($file)` - returns `array('name' => $name, 'group' => $group)`
* `debug_this_get_file_perms($file)` - returns string - Example: 0775
* `debug_this_convert_perms_to_rwx($perms)` - returns string - converts permission number to RWX format - Example: 0755 folder becomes drwxr-xr-x
