You can now make any app end-user-programmable -- as long as it's built in LÖVE

08/24/2023, 10:46 AM@Kartik Agaram have you poked around the way fennel-folks tackle this?
I like your way better because it is all lua+love, no emacs 😆

I've played with Fennel very slightly, though I haven't tried to set up any emacs integration.
I have no doubt Emacs is far more powerful in these capabilities. Hopefully my stuff can act as a gateway drug for a few people.

I think the main guy behind fennel even has a package specifically for doing it. Sort of like an embeddable editor.

Thanks! I don't think I'd ever actually tried this, even though I follow technomancy on Mastodon. People are too retiring about plugging their stuff, compared to me 😆 I'm going to try it out.

Oh, Polywell doesn't even require Emacs.

The original blog post says an error crashes the whole app. And I spot checked a few places in Polywell from my phone and didn't see any error handling. So maybe that's one difference. Both my driver.love and this new approach are robust to errors. (The motivation for this new approach: someone was trying to use driver.love on iPad, where the OS only permits one LÖVE app to run at a time.)
There's also a minor difference in the communication mechanism. Polywell uses a separate thread, but it seems to be just to get non-blocking I/O. driver.love uses a temporary file for the same purpose. Feels like fewer moving parts, but this is subjective.
There's no reason you couldn't read/write the temporary file from Emacs and get all its sweet sweet power. Conversely, there's no reason you couldn't switch Polywell to driver.love's error handling and/or simpler communication mechanism.

Ah never mind, Polywell does use `xpcall`: https://git.sr.ht/~technomancy/polywell/tree/main/item/config/console.fnl#L42
