rust-hot-reloading VS ihp

Yes https://fasterthanli.me/articles/so-you-want-to-live-reload-... (discussed here https://www.reddit.com/r/rust/comments/j0ajdy/so_you_want_to...)

And then there's this crate https://docs.rs/live-reload/0.2.0/live_reload/ which works on the same principles as the article above, and is based on C code (i.e. the same approach works for C).

There's a bunch of other libraries that work the same way, and some example code that can do this. I can find https://github.com/irh/rust-hot-reloading and https://github.com/porglezomp-misc/live-reloading-rs and https://github.com/xixixao/hot-reload-rs

And then there's https://github.com/emoon/dynamic_reload which is perhaps better?

And there's https://github.com/draivin/rust-hotswap which has a nice API but uses a deprecated rustc internal API doesn't build anymore.

Anyway there was a library that did this in a more elegant way and I just can't find it (perhaps it was rust-hotswap anyway).

I see the Nannou part of your question was answered, but to the other part: You can hot-reload in a compiled language, I'd just generally advise against it without specific toolchain support or some other kind of runtime support (since this is a system language you can do it yourself). There are some people who do it, and more power to them. For example: https://github.com/irh/rust-hot-reloading

I found IHP straightforward:

https://ihp.digitallyinduced.com/

despite not remembering much haskell!

This assumes you can get past nix for the install.

I find IHP well-designed. I just wish the licensing scheme were more transparent.

You can find the docs at https://ihp.digitallyinduced.com/ and some getting started videos at https://www.youtube.com/watch?v=PLl9Sjq6Nzc&list=PLenFm8BWuKlS0IaE31DmKB_PbkMLmwWmG

In case this got you interested in Haskell, and you want a good way to start your Haskell journey (and have something to apply the optimization handbook to), check out IHP. It's the Rails/Laravel of the Haskell world. You can start here https://ihp.digitallyinduced.com/Guide/index.html or check it out on GitHub here https://github.com/digitallyinduced/ihp

At IHP we've been using Algora for a while now and it works really great. Here's e.g. one PR that was merged last week with a bounty attached https://github.com/digitallyinduced/ihp/issues/1621 Everything was set up in less than 15 minutes and ioannis and zafer have been super helpful with any questions we had.

In general I think this is a good direction and an interesting take on the open question around sustainable open source. Congrats on the launch and keep up the great work! :)

You could contribute to IHP! We have some great docs to get started here https://github.com/digitallyinduced/ihp/blob/master/CONTRIBUTING.md And we have some low hanging fruits in GitHub issues for you to get started with, e.g. https://github.com/digitallyinduced/ihp/issues/1601 (also there's always lots of activity in the IHP Slack, in case you have any questions/need help)
