What's New in Wing IDE 5.1

Multi-process Debugging

Wing Pro can now debug multiple processes at once. By default, Wing will accept multiple debug connections, showing a process selector wherever a stack selector is shown in the user interface, in addition to a thread selector if there are multiple threads in the debug process. The process selector groups processes into a process tree, showing the relationship between them regardless of how they were created or debug-enabled.

You can also ask Wing to automatically debug child processes. This is off by default since it can be confusing to new users, or unwanted in some code bases, but can be enabled with the Debugger > Processes > Debug Child Processes preference or the Debug/Execute > Debug Child Properties setting in Project Properties.

Wing can automatically debug child processes created with the multiprocessing module, with os.fork() (on Posix platforms) or whenever a process is started using sys.executable. In other cases, wingdbstub can be used to start debugging in the child process.

Additional features for debug process control are available in the Processes sub-menu of the Debug menu and the Debugger > Processes preferences group.

More information can be found in Multi-Process Debugging in the Wing IDE manual.

Improved Python Shell and Debug Probe

The Python Shell and Debug Probe now syntax highlight code, as in the editor. The shells now also show data value tooltips when the mouse hovers over symbols.

Improved Testing Tool

The Testing tool in Wing Pro now supports the pytest unit testing framework and saves results in the project file, along with the date the test was last run.

  • Added a way to send keys to the editor via the scripting API
  • Added preference for type of split created by Goto Definition in Other Split
  • Added ability to copy selected result line, message, or line number from PyLint results (thanks to Viktor Lucza)
  • Added a close-all-readonly command to close any read-only files
  • Support for recent Google App Engine versions
  • Improved auto-completion for PyQt
  • Improved Find Symbol dialog

See the change log for details.

Not all of these features are available in Wing IDE Personal and Wing IDE 101. For details, see the feature list and What's New in Wing IDE 5.

Compatibility Notes

Whenever possible, we recommend upgrading debugger installations used for remote debugging to match the current IDE version. However, this release can remote debug with debugger cores dating back to version 5.1.0. Any earlier versions will need to be updated to match the current release.

Wing 5.1 drops support for Python 3.0 (but not 3.1+, of course!) and makes a few other minor changes listed in the change log.

By default, Wing 5.1 will install over your Wing 5.0 installation. To avoid this: On Windows, uncheck the option to remove Wing 5.0 or use the .zip installer; on Linux use the tar file installer; on OS X, unpack the OS X disk image to a location other than your Applications folder.

Wing 5.1 and 5.0 can share project files, but we recommend backing up your projects if you plan to move back and forth between the two versions.
