How to Use Scripts

What are Scripts?

Scripts are reusable Lua functions callable from Workflows, Custom Actions, and Custom Apps. They encapsulate logic you want to share across multiple Workflows.

Script roles

Role	Use case
Script	General-purpose Lua, called from Workflow Script nodes
JDF Template	Generates JDF job tickets for press equipment
JMF Template	Generates JMF messages for machine communication
ML Data Query	Returns training data for ML model training

How to create a Script

1. Go to Menu → Developer → Scripts
2. Click + New Script
3. Enter a Name and select the Role
4. Write the Lua code in the editor
5. Click Save

Calling a Script from a Workflow

Add a Script node, select the saved Script, and map input variables from the Workflow context. The return value is the node output.

Example

-- Calculates a priority score from values passed into the script
local remaining_days = input.remaining_days or 0
local weight = input.tier == "premium" and 2 or 1
return math.max(0, (10 - remaining_days) * weight)
