This topic shows you how to enter and execute code in the interactive Workbench command prompt or the editor after you launch a session.
The editor is best for code you want to keep, while the command prompt is best for quick interactive exploration.
Command Prompt - The command prompt functions largely like any other. Enter a command and press Enter to execute it. If you want to enter more than one line of code, use Shift+Enter to move to the next line. The output of your code, including plots, appears in the console.
If you created your project from a template, you should see project files in the editor. You can open a file in the editor by clicking the file name in the file navigation bar on the left.
Editor - To run code from the editor:
- Select a script from the project files on the left sidebar.
- To run the whole script click on the top navigation bar, or, highlight the code you want to run and press Ctrl+Enter (Windows/Linux) or cmd+Enter (macOS).
When doing real analysis, writing and executing your code from the editor rather than the command prompt makes it easy to iteratively develop your code and save it along the way.
If you require more space for your editor, you can collapse the file list by double-clicking between the file list pane and the editor pane. You can hide the editor using editor's View menu.
The Python and R kernels include support for automatic code completion, both in the editor and the command prompt. Use single tab to display suggestions and double tab for autocomplete.
Project Code Files
All project files are stored to persistent storage within the
respective project directory at
/var/lib/cdsw/current/projects. They can be
accessed within the project just as you would in a typical directory
structure. For example, you can import functions from one file to
another within the same project.
