**************************************
Docker on Windows: Xdebug for PhpStorm
**************************************

Docker for Windows requires a well known IP address in order to connect to the host operating
system.

**Table of Contents**

Prerequisites
=============

General
-------

Ensure you know how to customize ``php.ini`` values for the Devilbox and have a rough understanding
about common Xdebug options.

.. seealso::
   * :ref:`php_ini`
   * :ref:`configure_php_xdebug_options`

Gather Host IP address
----------------------

On Windows you will have to manually retrieve the IP address to which Xdebug should connect to
via ``xdebug.remote_host``.

When gathering the Windows host IP address you will need to distinguish between two cases depending
on your configuration:

1. DockerNat IP address (no custom configuration applied)
2. Virtual Switch IP address (you have created a Virtual Switch to allow Internet access to your container)

Only one of the options may be valid for your setup.

DockerNAT IP address
^^^^^^^^^^^^^^^^^^^^

1. Open command line
2. Enter ``ipconfig``
3. Look for the IP4 address in ``DockerNAT`` (e.g.: ``192.168.0.12``)

   .. important::
      ``192.168.0.12`` is meant as an example and will eventually differ on your system.
      Ensure you substitute it with the correct IP address.

   .. seealso:: :ref:`howto_open_terminal_on_win`

Virtual Switch IP address
^^^^^^^^^^^^^^^^^^^^^^^^^

When you have created a custom Virtual Switch for you Docker setup, you will have to gather the
Virtual Switch IP address instead of the DockerNat IP address.

Let's assume you have created the switch by the name **New Virtual Switch** as follows:

   .. include:: /_includes/figures/xdebug/windows/virtual-switch-manager.rst


1. Open command line
2. Enter ``ipconfig``
3. Look for the IP4 address in ``New Virtual Switch`` (e.g.: ``192.168.0.12``)

   .. include:: /_includes/figures/xdebug/windows/ipconfig.rst

.. important::
      ``192.168.0.12`` is meant as an example and will eventually differ on your system.
      Ensure you substitute it with the correct IP address.

.. seealso:: :ref:`howto_open_terminal_on_win`


Assumption
==========

For the sake of this example, we will assume the following settings and file system paths:

+------------------------------+------------------------------------------+
| Directory                    | Path                                     |
+==============================+==========================================+
| Devilbox git directory       | ``/home/cytopia/repo/devilbox``          |
+------------------------------+------------------------------------------+
| :ref:`env_httpd_datadir`     | ``./data/www``                           |
+------------------------------+------------------------------------------+
| Resulting local project path | ``/home/cytopia/repo/devilbox/data/www`` |
+------------------------------+------------------------------------------+
| Selected PHP version         | ``5.6``                                  |
+------------------------------+------------------------------------------+
| DockerNAT IP address         | ``192.168.0.12``                         |
+------------------------------+------------------------------------------+
| Virtual Switch IP address    | ``192.168.0.12``                         |
+------------------------------+------------------------------------------+

The **Resulting local project path** is the path where all projects are stored locally on your
host operating system. No matter what this path is, the equivalent remote path (inside the Docker
container) is always ``/shared/httpd``.

.. important:: Remember this, when it comes to path mapping in your IDE/editor configuration.


Configuration
=============

Configure PhpStorm
------------------

**1. Ensure Xdebug port is set to 9000**

   .. include:: /_includes/figures/xdebug/phpstorm-settings.rst

**2. Set path mapping**

   Create a new PHP server and set a path mapping. This tutorial assumes your local Devilbox projects
   to be in ``./data/www`` of the Devilbox git directory:

   .. include:: /_includes/figures/xdebug/phpstorm-path-mapping.rst

   .. important::
      Recall the path settings from the *Assumption* section and adjust if your configuration differs!

**3. Ensure DBGp proxy settings are configured**

   .. include:: /_includes/figures/xdebug/phpstorm-dbgp-proxy.rst

Configure php.ini
-----------------

.. note:: The following example show how to configure PHP Xdebug for PHP 5.6:

Create an ``xdebug.ini`` file (must end by ``.ini``):

   .. code-block:: bash

      # Navigate to the Devilbox git directory
      host> cd path/to/devilbox

      # Navigate to PHP 5.6 ini configuration directory
      host> cd cfg/php-ini-5.6/

      # Create and open debug.ini file
      host> vi xdebug.ini

Copy/paste all of the following lines into the above created ``xdebug.ini`` file:

   .. code-block:: ini
      :caption: xdebug.ini
      :emphasize-lines: 7,8,11

      ; Defaults
      xdebug.default_enable=1
      xdebug.remote_enable=1
      xdebug.remote_port=9000

      ; The Windows way
      xdebug.remote_connect_back=0
      xdebug.remote_host=192.168.0.12

      ; idekey value is specific to PhpStorm
      xdebug.idekey=PHPSTORM

      ; Optional: Set to true to always auto-start xdebug
      xdebug.remote_autostart=false

.. important:: Ensure you have retrieved the correct ``DockerNAT`` IP address as stated in the prerequisites section above!

.. note:: Host os and editor specific settings are highlighted in yellow and are worth googling to get a better understanding of the tools you use and to be more efficient at troubleshooting.


Restart the Devilbox
--------------------

Restarting the Devilbox is important in order for it to read the new PHP settings.
Note that the following example only starts up PHP, HTTPD and Bind.

.. code-block:: bash

   # Navigate to the Devilbox git directory
   host> cd path/to/devilbox

   # Stop, remove stopped container and start
   host> docker-compose stop
   host> docker-compose rm
   host> docker-compose up php httpd bind
