| 125 | lvd | 1 | scratch area + TODO keeper for sjasmplus developers: |
| 2 | ==================================================== |
||
| 3 | |||
| 4 | |||
| 5 | ==================== |
||
| 6 | Ped: |
||
| 7 | |||
| 8 | LUA quirks: |
||
| 9 | -- v includelua: |
||
| 10 | function inc_ld(reg, val) |
||
| 11 | _pc('LD '..reg..','..val) |
||
| 12 | end |
||
| 13 | -- v kode: |
||
| 14 | LUA |
||
| 15 | inc_ld(A, pass) -- bug, should be 'A' |
||
| 16 | ENDLUA |
||
| 17 | = no output, no error, just dies. ... Seems like any LUA syntax error does that, just dies. |
||
| 18 | |||
| 19 | CSPECTMAP - needs better support for DISP and instances of STRUCT |
||
| 20 | |||
| 21 | --syntax: "I" to uppercase all labels + usage (needs labels refactoring) |
||
| 22 | |||
| 23 | --syntax: B+L options implementation |
||
| 24 | add DOCS example test: "hl: ld a,(hl),,de,hl" when all is implemented |
||
| 25 | |||
| 26 | static analysis: PVS-Studio https://www.viva64.com/en/m/0036/ |
||
| 27 | |||
| 28 | FIXME in sources mark further points worth refactoring |
||
| 29 | |||
| 30 | FIXME: get rid of ParseDirective_REPT somehow, its existence can't be right |
||
| 31 | (breaks ` .34 repeatX` directive probably? .. and END@beginningOfLine? .. actually not?) |
||
| 32 | |||
| 33 | SplitLuaErrorMessage - add some tests after Liniya fix, maybe review the code more. |
||
| 34 | |||
| 35 | "--lst" bez hodnoty nech spravi default nazov sam |
||
| 36 | ==> needs tests (badly, was bugged a lot during development) |
||
| 37 | |||
| 38 | ReadBufLine parsing refactored. Now look for other parts of code trying to do similar things and refactor too.. |
||
| 39 | |||
| 40 | I almost certainly broke some STRCPY/STRCAT max-size limits (i.e. malicious source may buffer overflow)... |
||
| 41 | |||
| 42 | Macro world issues: |
||
| 43 | - macros for operators? (in ideal case `zeuskeyaddr` possible to recreate in macro?) |
||
| 44 | - more operators, capable of some string manipulation and maybe some type/expression checks (islabel) |
||
| 45 | - ability to issue real instruction (ignoring possible macro of same name) |
||
| 46 | |||
| 47 | Input file without extension does produce wrong default output filename |
||
| 48 | |||
| 49 | SAVEHOB/SAVETRD/SAVETAP/... global review of filename handling, adding warnings/errors |
||
| 50 | where filename modification happens or filename is invalid. |
||
| 51 | |||
| 52 | ** Macro/define substitution rules and implementation (proposal): |
||
| 53 | - macro arguments substitute with priority, from the longest ones |
||
| 54 | - macro arguments substitute even in define related directives |
||
| 55 | - define arguments substitute next, from the longest ones (inc. defarray) |
||
| 56 | - name of define/macroarg starting with underscore prohibits substitution into middle |
||
| 57 | (can substitute only at beginning) |
||
| 58 | ? extend that rule to underscore at end sealing also the tail? |
||
| 59 | - lock some keywords for define/etc... at least put them under warning |
||
| 60 | - inhibitor of substitutions/macros happening (like `@djnz` always assembled as djnz inst. |
||
| 61 | ** Current refactored implementation: |
||
| 62 | - doesn't play priorities as proposed above |
||
| 63 | - evaluation of defarray index is still flaky and doesn't work correctly inside macro/etc |
||
| 64 | - needs lot more testing and cleanup |
||
| 65 | + should be already a bit more intuitive than 1.08+ (although it may break legacy source) |
||
| 66 | |||
| 67 | ZX128 snapshot default state and mapping - still doesn't survive simple `ret` into BASIC |
||
| 68 | |||
| 69 | DISP inside DISP bugs => documented. Correct solution = nesting DISPs?! |
||
| 70 | |||
| 71 | $$label operator to get label page. (and fix pages for defl/equ/expression/... labels) |
||
| 72 | //// syntax summary: |
||
| 73 | labels (\.|@|)[A-Za-z_][A-Za-z0-9_.?!#@]* |
||
| 74 | , argument-separator : instruction-separator ; // comment |
||
| 75 | # $ hexnums, % binary, "' strings, () parentheses or memcell, [] memcell, {} device mem |
||
| 76 | operators-unary: ! ~ + - low high not |
||
| 77 | operators-binary: * / % mod + - << >> >>> shl shr <? >? < > <= >= = == != & and ^ xor | or && || |
||
| 78 | us keyboard: ~!@#$%^&*()_+`-=[]{};':"<>?,./\| |
||
| 79 | $$label - hexa are single $ only, so this looks fine (unary operator) |
||
| 80 | ?label - 5<?label => ambiguous |
||
| 81 | \label - looks weird, no syntax clash |
||
| 82 | Needs more syntax: |
||
| 83 | - reformat label into different slot... <slot>$$expression ? (binary operator) |
||
| 84 | - differentiate 16+b address space from 16b slot-mapped address space. |
||
| 85 | &label/expression? Similar to C/C++? &0x1231241 ? (5123 + &1234) |
||
| 86 | |||
| 87 | MMU: |
||
| 88 | - custom pages order for wrap-next-mapping option (like "<3, 5, 1, 2>" ?) |
||
| 89 | - err/warn/warp option for slot range? |
||
| 90 | |||
| 91 | sjasmplus 2.x/fork: |
||
| 92 | |||
| 93 | address space of labels -> 2|3:30|29 bits, the top bits being default slot number, |
||
| 94 | remaining bits being physical address into global chip address space |
||
| 95 | -> then producing machine code using the particular label would "format" physical |
||
| 96 | label value for particular "slot" (view of value). |
||
| 97 | |||
| 98 | To stay backward compatible/similar, one would have to support also 0000-FFFF range as if |
||
| 99 | going through the mapped pages.. but that does collide with early pages 0..n ... |
||
| 100 | How about abusing "@" or "." or something to distinguish between? (& resembles C/C++!) |
||
| 101 | |||
| 102 | Kate syntax: broken with LUA block containing "end" keyword (maybe even consider including Lua highlight rules from KDE defaults, if it's possible) |
||
| 103 | |||
| 104 | ==================== |
||
| 105 | Docs: |
||
| 106 | |||
| 107 | "pseudo-ops as SAVEBIN, SAVEHOB, SAVETRD, SAVETAP, PAGE, SLOT, LABELSLIST and use special functions in Lua scripts." |
||
| 108 | ^^ link each? |
||

| 110 | DEVICE needs better description? Issue #55 |
