Unfortunately, a JVM on wasm would be quite difficult for the same reason that Lisp over wasm is quite difficult (I had actually looked for wasm JVMs before trying anything). I had no idea there was a JS JVM implementation! That's very cool.

I think that the people who responded to you covered much of it, but you can find more by doing a web search for it. I'd find you links myself, but it's early in the morning and I'm a little tired.

My post is WCAG AA-compliant, except for the very specific occurrence of meaningless social links, and those meaningless social links render well in a browser's 'Reader View'. My site contains no ECMAScript aside from what was necessary to get the toy working. I care deeply about making things accessible; it's important to me.

It's not meant to be sold, it's just a little toy.

My aesthetic choices were intentional, and almost nothing in your comment is right.

However, the contrast is WCAG AA-conformant (except for the links that aren't in a black box, which aren't important links, as I went out of my way to confirm as I wrote the post). The page is actually pretty accessible.

Accessibility is important to me, as many people I've known in my life have been disabled, but so are silly aesthetic choices.

It was intentional, but it also was well-intentioned. That's why it's readable in more or less every web browser, regardless of whether it supports the one line of CSS I'm using, and accessible to screen readers (although I didn't throw in any elements specifically for them, the page is written simply enough that it should work, intentionally).

Your comment kind of shows some biases you might want to work on.

This is significant as it's the first time Common Lisp in particular has ever been hosted on it; wasm has a few poor decisions in its design that make it less-than-conducive to being a target for Common Lisp, and a lot of the more interesting implementations require an implementation to already be on the platform for bootstrapping purposes.

My previous attempts using other implementations haven't gone so well, despite throwing a lot of time at it (as an example, I have a fork of Eclipse Common Lisp, a defunct implementation from the 1990s, sitting on my disk with a few hundred lines of changes that I finally got to successfully compile and run a handful of very basic expressions, but it blows up when you try and define anything). In comparison, I was pleasantly surprised by how little I had to do, even though I did end up scrapping loads of lines of my own changes to npt in the process as I got a handle on how to make it work acceptably.

The Emscripten toolchain and I don't get along, partially because I don't like inlining ECMAScript into my C and vice-versa, so it's little more than a neat little demo right now.

You can load slightly more complex programs into it by hijacking the "imp" ECMAScript function every few hundred milliseconds with strings containing complete forms (this is essentially a batch processor, so there's no interactivity that allows it to wait while you decide what the rest of a form should be). Only one at a time, though. It's not that fancy.

If you mess up at all, even just a little error, it will crash. This is by design; I disabled the debugger. It's a giant hack, and the hack I eventually decided on left it impossible to have a debugging experience, with the benefit of getting to use a closer-to-unmodified npt.

This could be more useful, if I spent more time on it, but it's more fun if it's just a demo. I hope you enjoy the toy I made for you.

If you don't know what forms are in the context of Common Lisp:

Thanks for the article!

And when they pin comments, it's pretty obvious. dang often points it out: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...

YC isn't trustworthy, sure, but HN is.

Most people can't stare at the News source for an hour straight without getting a headache, let alone a rich investor type. They wouldn't find much of value in what's been publicly released of it, anyway (the released source is ancient and includes little as far as quality control goes).

If what you're saying is based in truth, you were probably just getting tips from someone with a strong financial incentive to have brute forced their way into understanding the site the manual way (throwing posts at it) rather than someone who had any genuine inside knowledge.

Genuine question.
