The Picolisp project has been around for ages and has been used for production work and is extremely impressive in my opinion. Generally speaking, only the APL family languages require less code (based off of looking at dozens of examples on Rosetta Code). Rebol is probably just as terse too, but not much else.

As a language it is tiny and easy to understand. It can interface to C or Java and Android. It also has a built-in prolog like system. I like many of the choices made by the creator "Alexander Burger".

The Lisp is native. This is a Java app that coordinates a native binary running pickup to present a web server that is used by the webview.

I have a node-red instance that does a similar thing, to allow drag-n-drop programming (Including UI), and (using dnr) heterogeneous cluster processing on mobiles (ios and android).

It starts a node-red server on the device, and uses cordova to host the webview.

I'm in the process of adding an ag-grid node so you can do complex UIs in the dev environment on the phone/tablet.

Got it, understood

oops, wrote picolisp, autocorrected to pickup

Oh? Why would you say that is?
