#RISC_OS finally after a month of battling, I have decoded and sucesfully reverse engineered the way ShareFS handle the distribution of updates to all connected clients! #ShareFSServer is now capable of updating all clients. Stay tuned for next build soon!

Happy New Year! 🎉 🥂
I’ve released a new theme manager for #RISC_OS (DME ExtTheme) and a beta update for LaunchPad, the application launcher.
Early beta testing is open now.

As questions about the previous post on #RISC_OS today's and tomorrow start flowing, I posted a new article with some answers to some of those. Please remember this is an open discussion, so if I have made errors please send me the corrections, thank you!

Finished to test the preliminary version of my new Desktop Theme Manager for #RISC_OS check out some screenshots here. I combines all old Theme managers into a single one fully rewritten in C:

Here is an article with all the details about a new chunk of progresses on #UltimaVM and the new project's mascot Luma. Still lots of work to finish to get the first beta release out, but hey I am moving forward!

Finally had some time to update #UltimaVM presentation article with all the latest improvements. I still need to publish the latest release of the Reference Manual, but at least the article is now up-to-date:

If you love Assembly, I am sure you'll love my #UltimASM #DSL it allows you to design the Assembly of your dreams or to code in #6502asm , #MC6809 , #mc68000 and even #VAX #ASM on #RISC_OS (and all other supported platform by my #UltimaVM).

Added #JVM Stack Operations mapping to my #UltimaVM (see link). But I am thinking of adding indirect adressing:
PUSH.U64 [r0-r1] Push mem val from addr in r0 to addr in r1
PUSH.F32 [r0] Push val at mem addr in r0 -
And while on the ROOL forum people are posting of using Linux, no resurrect RISCOSE, no something else, no nothing is possible for #RISC_OS is the typical old school mindset, #ProjectMerlin runs now on #AArch64, because if we don't start doing something, nothing will ever happen.

So, if you want to know what's going on this weekend with #MerlinOS (a brand new #RISC_OS redesigned from the ground up), check this blog post of mine:

A note on my #UltimaVM for #RISC_OS users: when coding on Ultima, we don't care at all about RO multistasking, we just code like on Windows, Linux or macOS. If we want to run an Ultima App in the desktop we just use the `--mt` option in the command line, everything else is handled by Ultima itself:👇

#ProjectMerlin work continues, and so do progresses:

#RISC_OS I've put together a presentation page for #ProjectMerlin, which also includes a real-time progress update widget. This is to help answer questions I've received from various people. Please note: I am doign this for fun, I am NOT trying to save #riscos .

It's alive! After a few years of battling with the #RISC_OS #kernel ... something new and magic is coming up very soon and oh boy if it's exciting! 😉

#OS_CLI (&05): Executes a supervisor command string pointed to by R0, null, linefeed, or return terminated. The command is processed as if typed in at the CLI. R0 is preserved. Command is limited to 256 bytes. Not re-entrant; interrupts are enabled.
-
#OS_ReadC (&04): Reads a character from the current input stream. On exit, R0 holds the ASCII code (C flag = 0) or an error code (C flag = 1, &1B indicates Escape). The input stream can be changed with OS_Byte 2. Not re-entrant; interrupts are enabled.

Added automatic disassembly for bytecode addresses that generated an exception in UltimaVM! Knowns the module, the address and thread/task. Nice touch it also disassemble the relative label is present and adds useful columns description, this below the error message:
#riscos #RISC_OS #vm #bytecode #disassembly #programming #coding
-
#OS_NewLine (&03): Outputs a line feed (ASCII 10) followed by a carriage return (ASCII 13) to the current output streams. This SWI is used to move the cursor to the start of a new line. Interrupts are enabled, and it is not re-entrant.
-
#OS_Write0 (&02): Outputs a null-terminated string from the address in R0. If WrchV is intercepted, it calls OS_WriteC; otherwise, it calls the VDU driver (faster). On exit, R0 points to the byte after the null terminator. IRQs are enabled. #riscos
-
#OS_Write0 (&02): Outputs a null-terminated string from the address in R0. If WrchV is intercepted, it calls OS_WriteC; otherwise, it calls the VDU driver (faster). On exit, R0 points to the byte after the null terminator. IRQs are enabled. #riscos
-
#OS_Write0 (&02): Outputs a null-terminated string from the address in R0. If WrchV is intercepted, it calls OS_WriteC; otherwise, it calls the VDU driver (faster). On exit, R0 points to the byte after the null terminator. IRQs are enabled. #riscos
-
#OS_Write0 (&02): Outputs a null-terminated string from the address in R0. If WrchV is intercepted, it calls OS_WriteC; otherwise, it calls the VDU driver (faster). On exit, R0 points to the byte after the null terminator. IRQs are enabled. #riscos

#OS_Write0 (&02): Outputs a null-terminated string from the address in R0. If WrchV is intercepted, it calls OS_WriteC; otherwise, it calls the VDU driver (faster). On exit, R0 points to the byte after the null terminator. IRQs are enabled. #riscos
-
OS_WriteS (&01): Outputs a null-terminated string directly following the SWI in memory to the current output stream. The return address is modified to skip the string. Not re-entrant; interrupts are enabled. Use for efficient embedded string output.
-
#OS_WriteC (&00): Outputs a single character (ASCII code in R0) to the current output stream. If the stream is a terminal, the character appears on-screen. Invalid codes are ignored. Preserves registers (except R0). Use for direct character output.
