yes, sjasmplus has Lua 5.1.5 ( https://github.com/z00m128/sjasmplus/issues/73 )Цитата:

And AFAIK that's the last easy-to-upgrade-to version, anything newer requires a bit more more effort on sjasmplus side, and also there's some stuff I never truly understood how it was produced, and I would need to learn more about lua to resolve it.
Another day, anotherintro… macro
try to create autoreplacement for JR/JP
if code like:Код:macro _jpz to
if $-to<127 or to-$<127
jr z,to
else
jp z,to
endif
endm
all ok.Код:label
_jpz label
if code like:
got warning — warning[fwdref]: [LUA] forward reference of symbolКод:_jpz label
label
code compiles without errors, but I don't like the warning messages also
You can suppress warning if you know the code works as intended, add comment fwdref-ok
and the "to-$<127" can be "to-$<129". Jr is relative to "$+2" and can be -128..+127Код:macro _jpz to
if $-to<127 or to-$<127 ; fwdref-ok
jr z,to
else
jp z,to
endif
endm
But I would recommend you to not do this, IMHO (and also in my experience), it's lot easier to just use JR everywhere, and then modify it to JP when assembling fails due to range.
Your macro may cause unstable machine code size and if two+ of these macros keep switching on/off each other, 3-pass assembling is not enough to stabilise the labels, and you may end with invalid machine code (especially with forward reference labels).
If you are using this, you should have some good way how to test every important build if it is correct and works, and unless you are using some kind of automated tests, it sounds to me like more extra work, than doing jr/jp manually in source. (then again, I usually write very small asm projects where I have no issue to modify 10-20 jump lines by hand and also I know where I want JR and where JP, so your mileage may vary).
а есть ли возможность добавить поддержку команд и режимов памяти Rabbit 2000?

but you need somebody who will do it.
I can help, but I would need somebody with R2000 expertise to explain me differences, which opcodes to add and which to remove, write/check tests and help to design extra syntax to make it useful with the extended memory model, etc..
Ie. at least one very experienced R2000 coder willing to work on sjasmplus is missing right now.
From a quick look at docs I'm missing some simple "this is how it differs from Z80" condensed to 1-3 pages, the changes seems to be small, but non-trivial, and after reading like 10 pages of CPU user manual I haven't learned much, except that it's different enough to need serious work to implement.
hello
Is there a built-in text converter from Unicode to cp1251?
No, there's almost zero bytes in sjasmplus dealing with encoding, except hard-coded cp1251 to dos-866 conversion, and detection of UTF16/32 BOM bytes at beginning to reject file.
sjasmplus treats source files as 8bit extended ASCII, (0x00,0x0A,0x0D inside strings have to be encoded as \0,\n,\r and \ itself has to be \\), so what bytes you have in source will be outputted into binary too.
For converting your regular source editor encoding to target ZX encoding I would suggest using some tool like iconv as part of make rule (or using the target encoding directly in text editor).
Use LUA, Luke!Цитата:

Добавляешь макрос:
Затем в коде:Код:includelua "_u.lua"
macro db_u text
define _t text
lua ALLPASS
local str = sj.get_define("_t")
str = string.gsub(str, ".?$","")
str = string.gsub(str, "^.?","")
_u(str)
endlua
undefine _t
endm
В результате получишь db 127Код:db_u " © "
Большая часть символов реализована, русские буквы соответствуют cp866, но спецсимволы немного отличаются, при желании коды символов можно поменять на нужные.
That's very nice script, just minor detail:
that removes any first and last byte of the argument, if you want that, you can skip regex completely and do the simpler: str = string.sub(str,2,-2)Цитата:

or if you want to remove only quotes and do no change to string without quotes, you can use more specific gsub regex: str = string.gsub(str,"^"(.*)"$","%1")
I would still rather use `iconv` which is more complete and can convert from many encodings to many encodings, and is available almost everywhere in *NIX world (not sure about windows, I guess with win10 and later you can just simply move everything to WSL and use linux inside windows, to avoid all the windows troubles and deficiencies in tools). But if you don't want to depend on external tool, this script is nice and easy to patch if one needs something new or non-standard.
https://github.com/z00m128/sjasmplus...es/tag/v1.19.0
- added Amstrad CPC devices (AMSTRADCPC464, AMSTRADCPC6128) - by Oli Wilkinson
- added Amstrad CPC save snapshot and CDT (SAVECPCSNA, SAVECDT) - by Oli Wilkinson
- added SAVE3DOS (like SAVEBIN with +3DOS header)
- the deprecated "ok" warning suppression is removed, use "<warning-id>-ok" comment or -Wno-...
- new temporary label suffix syntax _b and _f, enabling them for all expressions
- fix --longptr mode to keep 32b address when DS 0 is used
- added fake instructions adc|add|sbc|sub de,bc|de|hl|sp
- dec|inc|pop|push will accept also single-comma multiarg in --syntax=a mode
- DUP/REPT will now accept also zero count (skipping the block)
- DEFL labels can be defined even as late as in last pass
- bugfixes (macros, listing, file names in errors, SLD reversepop data)
So Neo can finally abuse the temporary labels to address backward/forward inside macros even with `ld (123_b+1),hl` ... :)
Have a great time, and looking forward to new ZX/GB/MSX/CPC/Next productions...
And thank you all for reporting issues and helping to steer the development, and your feedback. Really happy to read your messages. :)
