To change an option from its default, you #: must import ``pyglet`` before any sub-packages. For example:: #: #: import pyglet #: pyglet.options['debug_gl'] = False #: #: The default options can be overridden from the OS environment. The #: corresponding environment variable for each option key is prefaced by #: ``PYGLET_``. For example, in Bash you can set the ``debug_gl`` option with:: #: #: PYGLET_DEBUG_GL=True; export PYGLET_DEBUG_GL #: #: For options requiring a tuple of values, separate each value with a comma. #: #: The non-development options are: #: #: audio #: A sequence of the names of audio modules to attempt to load, in #: order of preference. Valid driver names are: #: #: * xaudio2, the Windows Xaudio2 audio module (Windows only) #: * directsound, the Windows DirectSound audio module (Windows only) #: * pulse, the PulseAudio module (Linux only) #: * openal, the OpenAL audio module #: * silent, no audio #: debug_lib #: If True, prints the path of each dynamic library loaded. #: debug_gl #: If True, all calls to OpenGL functions are checked afterwards for #: errors using ``glGetError``. This will severely impact performance, #: but provides useful exceptions at the point of failure. By default, #: this option is enabled if ``__debug__`` is (i.e., if Python was not run #: with the -O option). It is disabled by default when pyglet is "frozen" #: within a py2exe or py2app library archive. #: shadow_window #: By default, pyglet creates a hidden window with a GL context when #: pyglet.gl is imported. This allows resources to be loaded before #: the application window is created, and permits GL objects to be #: shared between windows even after they've been closed. You can #: disable the creation of the shadow window by setting this option to #: False. #: #: Some OpenGL driver implementations may not support shared OpenGL #: contexts and may require disabling the shadow window (and all resources #: must be loaded after the window using them was created). Recommended #: for advanced developers only. #: #: .. versionadded:: 1.1 #: vsync #: If set, the `pyglet.window.Window.vsync` property is ignored, and #: this option overrides it (to either force vsync on or off). If unset, #: or set to None, the `pyglet.window.Window.vsync` property behaves #: as documented. #: xsync #: If set (the default), pyglet will attempt to synchronise the drawing of #: double-buffered windows to the border updates of the X11 window #: manager. This improves the appearance of the window during resize #: operations. This option only affects double-buffered windows on #: X11 servers supporting the Xsync extension with a window manager #: that implements the _NET_WM_SYNC_REQUEST protocol. #: #: .. versionadded:: 1.1 #: search_local_libs #: If False, pyglet won't try to search for libraries in the script #: directory and its `lib` subdirectory. This is useful to load a local #: library instead of the system installed version. This option is set #: to True by default. #: #: .. versionadded:: 1.2 #: options = { 'audio': ('xaudio2', 'directsound', 'openal', 'pulse', 'silent'), 'debug_font': False, 'debug_gl': not _enable_optimisations, 'debug_gl_trace': False, 'debug_gl_trace_args': False, 'debug_graphics_batch': False, 'debug_lib': False, 'debug_media': False, 'debug_texture': False, 'debug_trace': False, 'debug_trace_args': False, 'debug_trace_depth': 1, 'debug_trace_flush': True, 'debug_win32': False, 'debug_x11': False, 'graphics_vbo': True, 'shadow_window': True, 'vsync': None, 'xsync': True, 'xlib_fullscreen_override_redirect': False, 'search_local_libs': True, 'advanced_font_features': False, 'headless': False, 'headless_device': 0, 'win32_disable_shaping': False, 'dw_legacy_naming': False, 'com_mta': False, 'osx_alt_loop': False } _option_types = { 'audio': tuple, 'debug_font': bool, 'debug_gl': bool, 'debug_gl_trace': bool, 'debug_gl_trace_args': bool, 'debug_graphics_batch': bool, 'debug_lib': bool, 'debug_media': bool, 'debug_texture': bool, 'debug_trace': bool, 'debug_trace_args': bool, 'debug_trace_depth': int, 'debug_trace_flush': bool, 'debug_win32': bool, 'debug_x11': bool, 'graphics_vbo': bool, 'shadow_window': bool, 'vsync': bool, 'xsync': bool, 'xlib_fullscreen_override_redirect': bool, 'search_local_libs': bool, 'advanced_font_features': bool, 'headless': bool, 'headless_device': int, 'win32_disable_shaping': bool, 'dw_legacy_naming': bool, 'com_mta': bool, 'osx_alt_loop': bool, } for key in options: """Read defaults for options from environment""" assert key in _option_types, f"Option '{key}' must have a type set in _option_types." env = f'PYGLET_{key.upper()}' try: value = os.environ[env] if _option_types[key] is tuple: options[key] = value.split(',') elif _option_types[key] is bool: options[key] = value in ('true', 'TRUE', 'True', '1') elif _option_types[key] is int: options[key] = int(value) except KeyError: pass if compat_platform == 'cygwin': # This hack pretends that the posix-like ctypes provides windows # functionality.
