Steel for project

[lonnietc]

Hello,

I have just come across Sleel Lisp and really like what I have seen so far. Since I need a Lisp interpreter for my AI/ML project, I am strongly considering use it as it seems fast and I like the REPL interactive. I still need to learn some things with it but think that the integreation with Rust is also awesome and will prove useful since I need to make a hypergraph in lisp the this could be good.

Anyway, I was running your playground and found a few scm files that seemed to give errors and as I am not yet familiar with all of the Seel feature and lanfuage dynamics, I thought that I would report them to you as well.

Here they are: contracts.scm, stack_struct.scm, and trie.scm

I would like to start up the Steel Playground locally as well so is there any documentation on this?

Lastly, with the great power of Lisp, I much say that I like what you are trying to do with the unicode.scm so that you can define emoji as functions and operators. I hope that you will continue with that work as well and maybe in a new version when it is available then this will be working more since in theory, anthing in Lisp could be a function or operator.

Thanks and have a great day

I took a quick look at the playground and fixed the issues, the build was just out of date.

Running the playground should be pretty simple - you'll need npm and node 24. Then just npm run dev - you can find the playground here: https://github.com/mattwparas/steel-playground

The unicode stuff should work pretty well I think 😄 the comment is pretty old

Hi Matt,

Thanks so very much and I will go play with it.

I think that Steel may be just what I have been seeking for a good Lisp language implementation as being integrated with Rust is a real plus for what I am trying to do with some AI/ML research.

Thanks again and have a great day

UPDATE: Looks like the playground (yours online) contracts.scm example is still misbehaving but the others seem to run now.

I just tried to download and run the playground locally and got some errors which seems to suggest that I need to build the Steel wasm first, if I am guessing correctly:

[plugin:vite:import-analysis] Failed to resolve import "../pkg/web_wasm.js" from "js/wasm_loader.js". Does the file exist?

UPDATE: Turns out that I had to do this for the playground

# Download the playground
https://github.com/mattwparas/steel-playground.git
cd steel-playground

# Build the packages
rustup target add wasm32-unknown-unknown
cargo install wasm-pack
wasm-pack build --target web

# Run the playground
npm run --dev

# Start up a browser
Local:   http://localhost:5173/

The above seems to have worked for me.

Thanks again and have a great day

I think the contracts example is working as expected - it's supposed to fail there. It's demonstrating that the contracts are enforced

[lonnietc]

Thanks, then things are working as expected.

I really think that Seel will be good for my AI project.

On a side question, does Seel allow for FFI loading of shared libraries from other languages? I know that Rust has a bit of trouble in this area from what I have read since I wanted to build a type of universal plugin system and also wanted to be able to load libraries (dll/.so) from other langues.

Thanks again
