Android Question B4A Interpreter

[Adie]

Hi
I am looking for an interpreter that I can use to execute a .BAS file at runtime.
The B4A app must be able to post the variables to the interpreter and then call the code (maybe a SUB). On return from the sub the required variables must be 'read' back and local processing will continue.

I am porting an industrial control program from Windows (C++) to Android things. We currently use a product 'FastScript' that can compile C++ code on the fly and execute it almost at main app speed. It is seen as an object by the host app. All variables in the script have read/write access from the main app.

I looked at this: https://www.b4x.com/android/forum/t...-for-android-programming-on-the-device.41468/
As I am new (seldom use) to B4A I've got no clue where to start.

Any Ideas?

Check the Eval class: https://www.b4x.com/android/forum/threads/b4x-eval-expressions-evaluator.54629/#content

It is not built for running code. Only expressions. You can however extend it.

Whether it is practical or not depends on your requirements.

Ok, I found BeanShell, a full Java interpreter. Look Here: http://www.beanshell.org/intro.html

There is a downloadable .JAR file (bsh-core) which is all I need to 'get into B4A'

Questions:
1: how do I generate the .XML file from the JAR?
2: before I spend too much time on this, will this work?

And then I found BasicLib 1.4 from agraham that will work for now so I can carry on with the development.

I would prefer BeanShell. Still don't know how to access the subs in the BeanShell JAR file which I would like to use.
