Python Script - Live

Purpose

The Live Python device allows you to add Python scripts to your project as string control values, rather than creating individual functions on the Script tab. The main benefits are:

• Live editing of scripts at run-time without redeploying the project.
• Copying and pasting of scripts between projects instead of having to export and then import scripts.

The device has an editor icon on its control surface. Once you have emulated or deployed the project, you can double-click this icon to edit the script in an external editor.

When scripts are stored in Live Python devices, they are encrypted. If you place a Live Python device on a locked page, users who do not have the required access rights will not be able to view the script, either by clicking the editor icon or by viewing the project or plugin file.

Notes:

• Before you can type in or paste in script to the device, you must emulate or deploy the project.
• As Live Python devices allow live editing of script, making manual changes to script when a project is deployed and running must be done with caution, as a change could stop the project from functioning.

Tips:

• If you would like to use a different editor to the default one, on the Tools menu, click User Preferences, and then specify the path to the new editor in the Path box.
• You can automatically update the script in a Live Python device by wiring a Preset to the input node.
