Jython¶

Jython is a Python Interpreter written completely in Java. There are 2 ways to execute TimingAnalyzer Python scripts.

Select the script file from the script dialog window that is displayed when you select the File Menu -> Script.

From a dos command line window if you run the Windows OS, or from a shell command line window if you run a Linux or Unix OS.

Using the Script File Dialog from the TimingAnalyzer program.¶

Start the TimingAnalyzer

File Menu -> Script or Ctrl T. This brings up the Script selector dialog window.

Select the script, dff.py, then click the execute button.

The interpreter is started, then both the os and sys modules are imported, then the script is executed.

Using the Command Line¶

Change directory to the install directory of the program.

Start Jython.

Start the application

Execute scripts

The listing below shows that I started Jython in the install directory

Now execute the start_app.py script. This initializes the Jython interpreter so you can use all the TimingAnalyzer classes and methods.
