I have now written a #z80 machine code monitor for the #MailStation. The command set is very influenced by WozMon, but unlike #Woz I haven't managed to fit it in 256 bytes (yet...)

So now, in the strictest sense of the word, I have a #repl on this thing!

(While there was already a built-in hex editor, it was not suited to interactive use. A reboot was necessary to test changes, and it was restricted to writing dataflash, which has a limited number of write cycles.)

Hex editor displaying ranges of memory at 8000 and 8010-8017.
8000>c9
8010>00 00 00 00 00 00 00

At the bottom of the screen is a textbox containing the command
8000r
which when executed would call the code starting at address 8000 — Hex editor displaying ranges of memory at 8000 and 8010-8017. 8000>c9 8010>00 00 00 00 00 00 00 At the bottom of the screen is a textbox containing the command 8000r which when executed would call the code starting at address 8000

#Lisp #REPL s are these unique beasts, clean windows into the raw interactivity of the languages and a mold to build it from. They are text-only-ish, though. Which is not always optimal. In my new piece, I look at the state of art in #CommonLisp implementation REPLs and their customizabity, and try to advocate for using them still.

Did you know that Guile's metacommands are comming to Arei soon?
- That we already have an incredibly useful guile stack traces viewer?
- That Ares now works with stable version of Guile and doesn't require guile-next?
No? We got you covered:
