Hi,
regarding ECL in ARX/BRX - I have been to this page many times in my search for implementing a more 'native' Lisp environment for AutoCAD and BricsCAD and finally found some time and motivation to do something about it.
I have created a basic proof of concept plugin that embeds ECL within the host CAD application. Currently it only builds for BricsCAD but by linking the necessary lib's it will work with AutoCAD as well.
(note: I tried to post link to github repo but wasn't allowed)
Look on my GitHub page (MickDuprez) for EclRX
It's early days yet but a nice feature of this implementation of ECL is the ability to run a Swank server which can be connected to from Emacs with Slime with very little effort effectively giving you all of the power of editing Common lisp with a REPL. This should enable the ability to 'hot load' revised code into the host application while developing and testing, pretty cool!
I hope this can be of use to someone.
Cheers, Mick.
