2023-05-02 11:06:56 <mtm-        > is there any sort of C FFI for RetroForth (or Konilo)?  Specifically I'd like to have something where I could push a pointer to a C function and some arguments onto the data stack, execute a RetroForth word to call the C function and get the result back on the stack.  Looking at using RetroForth to write some games for the PlayDate: https://sdk.play.date/1.13.4/Inside%20Playdate%20with%20C.html

2023-05-02 12:02:26 <mtm-        > great, thanks! will check it out

2023-05-02 12:08:00 <mtm-        > btw, I like the tweaks you made to the site.  Is Konilo the evolution of the two non-nga VMs?

2023-05-02 12:41:37 <crc         > ilo started as napia, which was a mulitcore vm. The initial work proved very buggy, so it was simplified into ilo, then expanded back into a multicore system
2023-05-02 12:42:16 <crc         > konilo is the forth that runs on ilo & napia (and later arks; another ilo-derived vm one of my kids is working on)
2023-05-02 12:43:33 <crc         > at this point konilo on ilo is my primary daily system for note taking, small programs, and interactive use
2023-05-02 12:43:53 <crc         > alongside retroforth & nga for bigger things like my http servers, database work, and system scripts
2023-05-02 12:45:01 <crc         > I'm also using ilo for expermi
2023-05-02 12:45:40 <crc         > experiments with smaller targets like microcontrollers as it has the smallest requirements of my various systems
2023-05-02 12:58:03 <mtm-        > I see, interesting.  I've been thinking of porting one of your VMs to ARM assembly (my main machines are a Reform laptop (ARM A53) and a Mac Mini (M1)).
2023-05-02 13:11:18 <crc         > it may need some adjustment for A53, but http://fossils.retroforth.org:8000/ilo/file?name=vm/ilo-aarch64-linux.s&ci=tip is an AArch64/ARMv9 implementation of ilo that I run on my phone, under Termux; I've not tried adapting it for Mm
2023-05-02 13:11:23 <crc         > M1 yet
2023-05-02 13:12:45 <crc         > (this did start as a disassembly of the compiled c implementation, so probably not optimal vs a hand written implementation)
2023-05-02 14:26:56 <mtm-        > ah, neat.  that'll be a good starting point
