Is this Commodore?
If it looks like a Commodore, acts like a Commodore, and feels like a Commodore, is it a Commodore? Not always. This cbmish is not a Commodore, and not made by Commodore Business Machines (CBM). But it is like a Commodore, thus the "-ish" (means like).
Cbmish is like a Commodore. This web software solution provides the feel of a Commodore in a web browser. There's a retro look and feel. But with a more modern programming language.
But it says "READY." Is that BASIC? No, it is lying to you. It is not ready for commands. It won't PRINT or GOTO. It is only ready for typing at this point. You can navigate the screen with cursor keys and typing letters, numbers, punctuation, and other symbols. You can change colors, type PETSCII, change to upper/lowercase, switch to reverse characters. It does feel like a Commodore.
It also responds to mouse motion and clicks. That's not a Commodore I ever owned. Those rounded corners and text are buttons, and there are links too. Clicking on a rounded button will present the user with a relevant sample screen, or navigate to another web page. Colors may change, graphics may be drawn, text will display, and sprites may move.
So why do this? The about screen goes into some detail. I'm ready to move on from BASIC (gasp!) and 6502 Assembly (gasp!) and I don't really want to program on my Commodore (gasp!), but I do want to continue the look and feel of Commodore. My current efforts are web based and I have been using TypeScript from some years now. My skill is mostly is C languages (C, C++, C#) and while I had shunned web development for sometime, my professional and hobby efforts have collided with doing full-stack development including C# and also TypeScript.
You can code interactively using the browser developer tools, or you can launch Visual Code (or similar) with typescript compiler dependency to have code transpiled as soon as you save. Instructions for both are on github in the README (see link below).
10 PRINT "Hello ";: GOTO 10
So long story short, it's a fine time to do Commodore like programming on the web, in a modern language. Take the best of modern languages and pair that with the look and feel of a great retro computer. Are you keeping up with the Commodore? Because cbmish is keeping up with the web.
