Forgive my sass, but I'm getting really tired of CLI apps assuming I'm on a dark theme.
@rl_dane So if this CLI program is selecting one of the 16 VT(?) colors then this is just a theming issue with your terminal.
But if it's using 256-color or high/true -color or whatever it is, then it's the CLI program's fault for sure.

@golemwire

VGA yellow on VGA white is still unreadable.

@rl_dane Yeah I mean that if you opt for setting the default background to white, you should set the palette's yellow color to something darker so it's useable. I think terminal themes usually change the VGA colors (one StackOverflow post called it the "ANSI colors"; I don't think the colors have to be the VGA colors), treating it like a palette, and if more manual control is needed for colors (like with `lolcat` (lol) ), then a different standard (e.g. xterm 256-color) with more colors is used.

@golemwire

Experimenting with GWBASIC here, and it seems that you can't set the background to color 15/0xf (bright white), at least not in GWBASIC itself.

So I guess I'm supposed to use color 7 (#AAAAAA), but that's kinda dingy, I dunno. :P

I want my contrast, man!!!! 😆

@golemwire

Here's a screenshot. It's honestly all readable, but there's no way to set the background to color 15 (#FFFFFF)

@golemwire

Here's a mockup of what COLOR 14,15 (yellow on bright white) would like like, and yep, it's unreadable. XD

@rl_dane I have to say, when people post colors like that (such as #BF00FF , one of my favorites, which I call "computer purple"), I find it funny to look through its hashtag.

@golemwire

It is funny to see it as a hashtag.

Also, that is a very loud purple. XD

@rl_dane It's great for borders. When I select colors, I use it for temporary overlays. Works great for that.

@rl_dane Looking at the hashtag, apparently that's "electric purple", according to a bot that really wants us to know that. Meh. It's "computer purple" to me.

Anyway, believe it or not, GW-BASIC was one of my earliest programming environments, thanks to an older teacher who I guess was set in his ways. :P

@golemwire

I didn't use it extensively, but it was familiar to me, because the BASIC on both the Apple ][ and Commodore 64 was Microsoft BASIC.

Which was, for the record, a pretty terrible implementation. I mean, their floating point implementation was on... point, but the variables are just terrible. Only the first two letters are used. Also, all numbers are stored as strings internally. ACK. SLOW.

@rl_dane That sounds pretty painful. (MS hasn't changed, have they.)
Two chars per variable name would be nice for a 16-bit implementation, though.

@golemwire

BRAH, just use a look-up table. XD

@rl_dane Maybe my next ISA+emulator will be 16-bit. I've cooked up some ideas I think are pretty interesting. But for now I am a school subject. (...hmm)

@golemwire

This might be an interesting point for inspiration:

@rl_dane OOH, I had a professor who brought that up, actually! He's a fan of this sort of stuff. I had no idea it was an actual p-code/bytecode/ISA, I thought it was just a helper library.

I'll check it out, thanks for the inspiration 😁

@rl_dane @golemwire oooooh, chic!

@rl_dane @golemwire this is amazing. I bet ARM Thumb stole several parts of this idea.

And if he switched OPTBL and BRTBL around, he could have saved another byte.

@rl_dane @golemwire also, damn, don’t nerdsnipe me TWICE.
@rl_dane @golemwire those 1970s hairdos and clothes, on the other hand… *snigger…*
@rl_dane @golemwire it’s an 8-bit ISA for a 16-bit system though
@rl_dane
By the time it became QBASIC, MS BASIC used a Bytecode too.
@golemwire
@golemwire
MS BASIC improved after Commodore's version. Commodore famously negotiated a good deal for the first version, then refused to upgrade and add official fixes as they'd have to go onto the normal contract...
@rl_dane

@ddlyh @golemwire

Yes, this is why Commodore BASIC painfully lacked any commands for graphics and sound.

Kept the C64 crazy cheap, though. ;)

@rl_dane
*"Crazy Cheap" for an American computer anyway. A Commodore 64 sold for one heck of a lot more than a ZX Spectrum back in the day (especially if you bought the kit version) and had similar capabilities (excluding the lack of a proper soundchip on Sinclair Speccys - by the time of the +2B, they were ruthlessly cheap compared to the C64, with more memory and better sound!)
@golemwire
@rl_dane @golemwire you just have to reprogram the CRTC to not use blinking, then the blinking bit gets repurposed as intensity bit for the background.

@rl_dane @golemwire ok, nerdsniping completed.

Create a file WEISS.BAS in your DOSBOX C: or whereever:

10 X%=INP(&h3DA):OUT &h3C0,&h10:OUT &h3C0,4:COLOR 16,15:CLS

Make sure the file ends with CR+LF (I think I don’t need to spell out how for you). In case of doubt, jupp for DOS should default to CRLF mode and pressing ^OZ toggles it (the status line will show you which one is then active) in both jupp for DOS and jupp for Unix. (The change only affects newlines created AFTER that, so if you do need to toggle it, backspace/delete that newline and hit Enter to create it anew.)

Then, run gwbasic weiss on DOS. Enjoy.

@rl_dane @golemwire (if your machine is too fast, you need a delay loop (docs say at least 250 ns) before each OUT instruction)
@rl_dane @golemwire are you using the ancient MIT GW-BASIC or a recent binary?
@rl_dane @golemwire also, damn, don’t nerdsnipe me like that

@mirabilos @golemwire

Whatever came with DOS and Windows 3.1 on the old PCE.js emulator.

@rl_dane @golemwire that very much depends on which DOS. I was asking in case I needed to binary-patch it to fix the COLOUR command, but turns out I don’t, the thing I wrote even runs on a MIT GW-BASIC distro.
