- flyinghamsterThe one thing I lamented about the Apple II Plus (vs. the original with Integer BASIC) was that to make room for autostart, they had to rip out the mini-assembler in the Monitor ROM. That was the closest thing I ever saw to an assembly-language REPL before this. At least they were able to keep the disassembler.
- jhallenworldYou should support symbols... For example, the monitor on my 6800 / 6809 Exorciser simulator has this (the "Offset at..." is printed when it fixes forward references): ~/exorsim$ exor -d % a 1000 1000: start bra skip 1002: nop 1003: nop 1004: skip ldx #10 Offset at 1001 set to 02 1007: loop dex 1008: nop 1009: bne loop 100b: rts 100c: % sy 1007 loop 1004 skip 1000 start % u 1000 1000: 20 02 BRA $1004 1002: 01 NOP 1003: 01 NOP 1004: CE 00 0A LDX #$000A 1007: 09 DEX 1008: 01 NOP 1009: 26 FC BNE $1007 100B: 39 RTS What would be even better: "a" brings up a built-in mini-editor. When you exit, the code is assembled.https://github.com/jhallen/exorsim
- jottingerThe source code for this is apparently 8 years old: https://github.com/abagames/z80-replWith that said, I love the idea.
- networkedCool idea! The REPL needs to handle whitespace after an instruction with no operands: > ld c,20h 0E 20 (7 cycles) > ld c,20h [<-- trailing space here] 0E 20 (7 cycles) > nop 00 (4 cycles) > nop [<-- trailing space here] unknown instruction: nop I also wish I could select from the completion list with Tab without typing more of the instruction, fish-style. I.e., you press Tab to go through completion 1, completion 2, ..., completion N, completion 1 again with Enter to confirm your pick.
- torutofuthe fun part is how fast you can get back into Z80 muscle memory once the repl is giving you immediate feedback
- j4cobgarbyReally nice! Would be fun if there were a few examples that could be loaded into memory
