Method Descriptions
-------------------

.. _class_OS_method_alert:

Displays a modal dialog box utilizing the host OS.

.. _class_OS_method_can_draw:

- :ref:`bool<class_bool>` **can_draw** **(** **)** const

.. _class_OS_method_dump_memory_to_file:

- void **dump_memory_to_file** **(** :ref:`String<class_String>` file **)**

Dumps the memory allocation ringlist to a file (only works in debug).

Entry format per line: "Address - Size - Description".

.. _class_OS_method_dump_resources_to_file:

- void **dump_resources_to_file** **(** :ref:`String<class_String>` file **)**

Dumps all used resources to file (only works in debug).

Entry format per line: "Resource Type : Resource Location".

At the end of the file is a statistic of all used Resource Types.

.. _class_OS_method_execute:

- :ref:`int<class_int>` **execute** **(** :ref:`String<class_String>` path, :ref:`PoolStringArray<class_PoolStringArray>` arguments, :ref:`bool<class_bool>` blocking, :ref:`Array<class_Array>` output=[  ] **)**

Execute the file at the given path with the arguments passed as an array of strings. Platform path resolution will take place. The resolved file must exist and be executable.

The arguments are used in the given order and separated by a space, so ``OS.execute('ping', ['-w', '3', 'godotengine.org'], false)`` will resolve to ``ping -w 3 godotengine.org`` in the system's shell.

This method has slightly different behaviour based on whether the ``blocking`` mode is enabled.

When ``blocking`` is enabled, the Godot thread will pause its execution while waiting for the process to terminate. The shell output of the process will be written to the ``output`` array as a single string. When the process terminates, the Godot thread will resume execution.

When ``blocking`` is disabled, the Godot thread will continue while the new process runs. It is not possible to retrieve the shell output in non-blocking mode, so ``output`` will be empty.

The return value also depends on the blocking mode. When blocking, the method will return -2 (no process ID information is available in blocking mode). When non-blocking, the method returns a process ID, which you can use to monitor the process (and potentially terminate it with :ref:`kill<class_OS_method_kill>`). If the process forking (non-blocking) or opening (blocking) fails, the method will return -1.

Example of blocking mode and retrieving the shell output:

::

    var output = []
    OS.execute('ls', ['-l', '/tmp'], true, output)

Example of non-blocking mode, running another instance of the project and storing its process ID:

::

    var pid = OS.execute(OS.get_executable_path(), [], false)

If you wish to access a shell built-in or perform a composite command, a platform-specific shell can be invoked. For example:

::

    OS.execute('CMD.exe', ['/C', 'cd %TEMP% && dir'], true, output)

``OS.shell_open("https://godotengine.org")`` opens the default web browser on the official Godot website.

.. _class_OS_method_show_virtual_keyboard:

- void **show_virtual_keyboard** **(** :ref:`String<class_String>` existing_text="" **)**

Shows the virtual keyboard if the platform has one. The *existing_text* parameter is useful for implementing your own LineEdit, as it tells the virtual keyboard what text has already been typed (the virtual keyboard uses it for auto-correct and predictions).
