This is strictly against my usual policies. It’s not very British. I’m not going to reply to anything on this thread. But this may be interesting. Chris

Thanks for your interest again folks. Sorry this year has been a bit sparse on updates due to the death of my partner Aihua, and brother-in-law. Come chat at: #ChrysaLisp-OS:matrix.org Recommend element.io reader. Chris

The (def-struct) stuff is part of the assembler ! Not the Lisp. Same with (def-enum) etc. I am going to have to write a document to clearly state where these boundaries between the Lisp, the C-Script and the VP layers. I realise it's n

It means what it says ;) All objects used by the Lisp are instances of classes from the class library, ie that stuff in class/ folder. These instances are ref counted objects, as they are derefed and they drop to 0 refs they get deinit

That code is using the C-Script assembler prototyping macros. It will produce VP assembler output, but lets you work without worrying about registers while you're getting stuff going. Have a read through the docs/ASSIGNMENT.md fil

There is currently no GC, by choice, but I recently did some work to assist the Stats app that I added recently that could lead to me implementing a GC at some point in the future.

There is a start on documentation in the docs/ folder. I know it's sparse at present I do aim to add more over time. The system can build itself from source after clean, on my 2014 Macbook in under 0.4s. It's not exactly a st

It's not bound to any host OS. I am using SDL to provided a simple abstraction to open a Window and obtain key and mouse input. I use very little of the SDL features, just a rectangle fill and rectangle bit blit. See the gui/ctx&#

Just a quick comment till I can get home. There are three main layers of in use. The more Lisp like layer in apps/ and cmd/. The lowest level VP assembler and an assembler with stack variables and expression compiler I call C-Scri

Thanks again folks for the interest. You catch me yet again when I’m at work but I’ll try answer question in an hour or so once I get home. Regards to all. Chris

Yes, go grab a copy and start playing with some simple apps. I'd love others to get more involved. Expanding the demo apps and maybe adding useful features to the class libs. Maybe tweaking the VP optimiser with some extra cases. New p

Worth covering a few things about the project. I wasn't trying to create a Lisp, at least not at first. I started with a simple VP (Virtual Processor) macro set for NASM in order to look again at some issues raised by my old Taos OS ba

Hi folks. Chris Hinsley here. Thanks for the interest again. Sorry the README is a bit of a jumble. I’m just heading home from work ATM I’ll try answer questions best I can once I get back. Regards Chris

I'm afraid it really is gone :( Rusting on a shelf somewhere never to see the light of day again. However I did start an experimental project a while back to do a simple Taos like kernel over BSD/Linux in x86_64, VP macros and pro

Running a clean roomed P-Java stack on top of our VP translator on an 11MHz Arm and getting the footprint under 1MB was a serious achievement. And yep, the history of Smartphones would have been very different if Moto had shipped it ! The h

I agree with Dave, I was involved in arguing for a open version, as the CTO of Tao, so people could get their hands on, but it wasn't to be. :( With hindsight Tao should have done this. Chris
