C preprocessor for asm
by Valery Ushakov 20 Jan '23

20 Jan '23

Asm sources in Self currently use assembler's macro facilities that differ between clang and gas. Recent versions of clang asm is gas compatible, but then as far as I understand apple's clang is special. llvm's asm behaves differently if "IsDarwin" and the current llvm macro code in Self is effectively apple-only. I'm working on a NetBSD port and NetBSD supports both gcc and clang as system compilers. I will porbably look at the FreeBSD port too and FreeBSD is now clang only, afaik. This makes it a bit painful to work with the current asm sources. Would there be any objections to switching Self i386 asm sources to use the C pre-processor? NetBSD has been doing that for ages (for a large zoo of CPUs) and it's quite ok. Some examples https://github.com/NetBSD/src/blob/trunk/sys/arch/i386/include/asm.h https://github.com/NetBSD/src/blob/trunk/lib/libc/arch/i386/SYS.h just to give a general idea of what it looks like. So, e.g. start_exported_function currentFrame will just become start_exported_function(currentFrame) Or MACRO(ret_prim_error, error_code) ... ret_bad_type: ret_prim_error badTypeOffset will be #define ret_prim_error(error_code) \ ... ; \ ... ret_bad_type: ret_prim_error(badTypeOffset) -uwe

Nice article on Self via HackNews

"I’ve been reading a bunch of old papers from the Self project. It’s pretty incredible how many things they invented that are absolutely essential in modern, high-performance managed language runtimes. It might be the most influential programming language that most programmers have never heard of…” https://dubroy.com/blog/self/

UK Smalltalk User Group meeting - 28 December 2022
by Giovanni Corriga 19 Dec '22

19 Dec '22

For the UKSTUG 2023 holiday meeting, Simberon's David Buck will present Beagle Smalltalk. Over the past 8 years, David has been developing a Smalltalk virtual machine. He used it to release two Smalltalk Games written in VisualWorks to run on Andriod and iPhone devices. More recently, he's re-written the VM to use its own bytecode set and written his own Smalltalk compiler to make it a stand-alone Smalltalk environment called Beagle Smalltalk named after the ship that took Darwin on his voyage of discovery. David plans to release this as an open-source Smalltalk to help and encourage kids to explore the world of programming. In this talk, David presents the current status of the project and where he hopes to go with it. David Buck is the president of Simberon ( http://simberon.com/ ) - a company that has been providing Smalltalk training and consulting for over 25 years. Along with James Robertson, David produced the Industry Misinterpretations podcast and later the Smalltalk Reflections podcast with Craig Latta. David remains a Smalltalk enthusiast and works to spread the word about Smalltalk. This will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/290409453/ ) to receive the meeting details.
