Mar 02, 2020 It supports automatic garbage collection just like Java. Python can be easily integrated with C, C, COM, ActiveX, CORBA, and Java. Python’s bulk of the library is very portable and cross-platform compatible with UNIX, Windows, and Macintosh. Python can run on a wide variety of operating systems (Windows, Linux, and Mac) and has almost the. Generic Operating System Services¶ The modules described in this chapter provide interfaces to operating system features that are available on (almost) all operating systems, such as files and a clock. The interfaces are generally modeled after the Unix or C interfaces, but they are available on most other systems as well. Python offers an ideal structure and support for large programs. Python offers support for automatic garbage collection. It supports an interactive mode of testing and debugging. It offers high-level dynamic data types and also supports dynamic type checking. Python language can be integrated with Java, C, and C programming code; High-performance.
To support this type of development, a Python implementation written in Java is under development, which allows calling Python code from Java and vice versa. In this implementation, Python source code is translated to Java bytecode (with help from a run-time library to support Python 's dynamic semantics). Feb 05, 2007 Hello, On OS X the environment variable is DYLDLIBRARYPATH. Python support definitely works on that platform; it's used all the time, DbException is from the Berkeley DB library, and is the file libdbcxx-4.5.dylib.
We are pleased to introduce the first Python library to fully enable GUI testing of Mac applications via the Apple Accessibility API. This library was created out of desperation. Existing tools such as using appscript to send messages to accessibility objects are painful to write and slow to use. ATOMac has direct access to the API. It's fast and easy to use to write tests.
ATOMac requires a system running OS X and Xcode installed. It has been tested extensively on 10.6, 10.7, and 10.8. 10.5 may work. If you experience issues with ATOMac on a particular version of OS X, please open a ticket in the issue tracker.
Systemwide accessibility must be enabled. Check the checkbox: System Preferences > Universal Access > Enable access for assistive devices. Failure to enable this will result in ErrorAPIDisabled exceptions during some module usage.
Installation should be as simple as running the following command line, which will download, build and install ATOMac:
Once the atomac module is installed, you should be able to use it to launch an application:
2020-3-18 Your Photos library holds all your photos, albums, slideshows, and print projects. If your library is large, and you want to free up storage space on your Mac, turn on iCloud Photo Library and use Optimize Mac Storage, or move your library to an external. Copy mac photos library.
This should launch Automator. Next, get a reference to the UI Element for the application itself:
Now, we can find objects in the accessibility hierarchy:
Note that we retrieved an accessibility attribute from the Window object - AXTitle. ATOMac supports reading and writing of most attributes. Using Xcode's included accessibility inspector can provide a quick way to find these attributes.
There is a shortcut for getting the sheet object which bypasses accessing it through the Window object - ATOMac can search all objects in the hierarchy:
There are search methods for most types of accessibility objects. Each search method, such as windows, has a corresponding recursive search function, such as windowsR. The recursive search finds items that aren't just direct children, but children of children. These search methods can be given terms to identify specific elements. Note that * and ? can be used as wildcard match characters in all ATOMac search methods:
ATOMac has a method to search for UI Elements that match any number of criteria. The criteria are accessibility attributes:
FindFirst and FindFirstR return the first item found to match the criteria or None. FindAll and FindAllR return a list of all items that match the criteria or an empty list.
Objects are fairly versatile. You can get a list of supported attributes and actions on an object:
Performing an action is as natural as:
Any action can be triggered this way.
Starting with version 1.0.0, ATOMac now includes compatibility with LDTP, a cross platform automation library. This allows testers to write a single script that will automate test cases on Linux, Windows, and now Mac OS X. Information and documentation on LDTP can be found at the LDTP home page.
LDTP operation is virtually identical to the operation on Linux. The import mechanism is slightly different, since it is shipped with ATOMac. Cross platform scripts executing on the System Under Test should import the LDTP client as follows:
In the future, the LDTP client may be broken out into a separate platform independent module to ameliorate this issue.
Like the Linux platform, the LDTP daemon may be run on the SUT, enabling client/server testing by executing 'ldtp' at a shell prompt. See the LDTP documentation for more details on client/server operation.
Although ATOMac is fully functional and drives hundreds of automated test cases at VMware, we have a to-do list to make the project even better.
Feel free to submit pull requests against the project on Github. If you're interested in developing ATOMac itself, sign up to the pyatom-dev mailing list.
ATOMac is released under the GNU General Public License. See COPYING.txt for more details.

This is a fork of spacenav-plus, which is itself a fork of spacenav.
Minor modifications have been made to allow compilation on Mac OS X. It has been tested with OS X 10.10 Yosemite. A new libspnav wrapper in Python has been added, as well as a reimplementation of the official 3DconnexionClient Mac OS X SDK.
This is the driver daemon. It connects to the Space Mouse and sends event using the X Window System, if desired, and using a simple unix socket interface. It reads its configurations from the file /etc/spnavrc. An example config can be found in spacenavd/doc/example-spnavrc.
Sending the signals SIGUSR1 or SIGUSR2 to the daemon causes it to start or stop sending X11 events.
Sending SIGHUP will cause the daemon to reload the configuration file.
For more informations, take a look at spacenavd/README.
This is the optional graphical configuration utility for spacenavd. The required dependencies can be installed with MacPorts:
You’ll also need the XQuartz Server for this to work.
You will need to configure spacenavd with X11 support:
This is the library used by applications that want to interact with the driver daemon. I've made some small changes. When compiling on Mac OS X, the resulting dynamic library will be built as universal/fat binary.
This is my simple Python Wrapper using the libspnav dynamic library, providing pretty much the same interface. An example application is included and can be tested when executing the module itself.
This is my reimplementation of the official 3DconnexionClient Mac OS X Framework. It uses the original headers but reimplements the basic functionality using the libspnav library.
By default it will be installed to /Library/Frameworks. Many programs, for example Blender, will pick it up there and be able to use the spacenavd device.
For some other applications, it has to be dropped into the application bundle (you may want to backup the original one). This has been tested with Google Earth:
None of the programs I use regularly supports building with the spnav library on the Mac out of the box. To start, I’ve hacked support for the spnav library without using X11 into FreeCAD, which already supports spnav on Linux. The patches are in this repository, called 0001-Initialize-spacenavd-without-X11-if-not-available.patch and 0002-Added-Thread-polling-for-Spaceball-events-generating.patch in the patches/FreeCAD directory. They can be applied cleanly on top of FreeCAD commit bfaa8799edba35ae1609edb6205aaeacf37b73ff.
I’ve also modified the patch from Gert Menke to suit my setup. You can find 0001-Added-hacky-spnav-lib-support.patch in the patches/OpenSCAD directory. It can be applied cleanly on top of OpenSCAD commit 50441e85a2d0920af6a1a886b97edc001f4dc0ae.
