Executing Python 3 Code for PDF Parsing

Ignition

I've written code in Python 3.9.13 to search and parse PDFs using PyMuPDF.

How can I execute the code from Ignition, feeding it a PDF Ignition obtained through a web address/uploaded to the gateway, and then receiving an array as the code's output?

I am basically using Python 3 to search key words and phrases and then extract text near those key phrases and save them to an array that also contains the page number where it was found.

I know Jython does not support this library so are there any good methods to run Python 3 code? I am not well versed with any other language but I'm willing to try if it's possible to replicate functionality and makes things simpler for Ignition.

Use Java's ProcessBuilder (accessible from jython).

Do you think I'll have to develop a module with the SDK or is there another way to use ProcessBuilder in Ignition Designer to achieve the same function?

You already have it written in python3? I would just do what Phil said and use process builder to call your existing code/py file with appropriate arguments.

Ignition has jython. It is well-integrated into java, and can use java classes and objects with near-native flexibility. Search this forum for ProcessBuilder for examples that do not require using the SDK.
