roc VS min-sized-rust

Zig is not entirely unsafe. It provides quite a few compile time checks and primitives to catch memory leaks or prevent them altogether.

For those following along https://github.com/roc-lang/roc

I don't see how to make Single Page Apps, or really anything client side in Roc. I'm quite frustrated by https://github.com/roc-lang/roc/blob/main/roc-for-elm-progra... which doesn't answer this which is the first question imo.

Their FAQ is an eminently reasonable breakdown of their choices:

https://github.com/roc-lang/roc/blob/main/FAQ.md

I don't fully agree with all of the reasoning, but it's a reasonable position to stake.

If you forget what parametrisation and functions are, then Roc's modules look like they actually do that.

Maybe you're not aware of Elm?

https://elm-lang.org

Elm is really functional, unlike the likes of React that are just partially, kind of functional.

There's an attempt at bringing Elm to the desktop, the Roc language... here's an UI example written in Roc:

What are your thoughts on the direct descendant, Roc? [0] I know it's pre v0.1 so maybe you don't have any, but as a fellow Elm lover it seems pretty compelling on the surface albeit less directly frontend-dev focused.

I might be misunderstanding something, but, for example, look at this "host"/platform: https://github.com/roc-lang/roc/blob/main/examples/cli/tui-platform/host.zig

This is a good guide on building small Rust binaries: https://github.com/johnthagen/min-sized-rust

This talks about going to extreme lengths on making the smallest Rust binary possible, 400 bytes when it was written, https://darkcoding.net/software/a-very-small-rust-binary-ind...

The thing is, you lose a lot of nice features when you do this, like panic unwinding, debug symbols, stdlib… for kernel and some embedded development it’s definitely important, but for most use cases, does it matter?

Oh it was 137, haha. I will link you to this older comment of mine: https://news.ycombinator.com/item?id=29408906

Are you sure? If so then this is awesome news, but I'm a bit confused; the commit in that min-sized-rust repo adding `build-std` to the README was merged in August 2021: https://github.com/johnthagen/min-sized-rust/pull/30

Are you saying that at that point the feature still hadn't "landed in Rust nightly" until recently? If so then what's the difference between a feature just being available in Rust nightly, vs having "landed"?

Rust binaries are by default nowhere close to 500MB. If they are not small enough for you, you can try https://github.com/johnthagen/min-sized-rust. By avoiding the formatting machinery and using `panic_immediate_abort` you can get about the size of C binaries.

A useful reference: https://github.com/johnthagen/min-sized-rust

That must be without stripping. Also there are ways to reduce binary size. See e.g. [min-sized-rust](https://github.com/johnthagen/min-sized-rust). I've gotten stripped binaries of small cli utils less than 400KiB without doing anything special, less than 150 KiB by customizing profile settings and compressing with upx, and less than 30 KiB by replacing the std with the libc as the link shows. Haven't tried with fltk though...

This is not quite what you're asking, but it does also address the underlying concern: https://github.com/johnthagen/min-sized-rust
