I think that if this is integrated with Firefox, then it would be reasonable to offer the JS engine runtime as a UNO plugin to the document. This way i can make cross platform macros.

It is already possible to use JS, it is just sadly not documented. https://phpandmore.net/2012/10/22/libreoffice-javascript/
There is also bug 97827 for changing the engine.

So in the android version the javascript engine is already available? meaning i can make javascript macros under linux and have them work in the android viewer?

The Android viewer is a different story. If I had to guess, they probably don't work, but I really have no idea.

Ok i will try it out, when i get the chance. 

The intent of my bug was to suggest the enhancement that the firefox integration (in the android version which i assumed was the same as the core?), could re-use the firefox JS engine which it has to interact with already, with a UNO interface support javascript in a cross platform way.

I don't believe the Android version interacts with Firefox in any way.

The current engine, Rhino, is provided by Mozilla: https://developer.mozilla.org/en-US/docs/Mozilla/Projects/Rhino

In bug 97827, I proposed that Duktape could be used as the engine.
