[clarity-repl] Expose method to construct JSON abi from contract source

[aulneau]

I'm working on an index of clarity contracts, and I want the ability to convert a string representation (standard .clar contents as string) of a contract into a JSON ABI, similar to the results from the stacks-blockchain-api/node.

There are lots of use cases I have planned for it, but generally it's so I'm able to construct different views of a contract or find similarities between many.

@hugocaillard @lgalabru is there any way that I can hack on something to get this working? such as can I use this https://github.com/stacks-network/stacks-blockchain/blob/master/clarity/src/vm/analysis/contract_interface_builder/mod.rs as a wasm module?

[hugocaillard]

Hey @aulneau,
Is think the idea would be to expose build_contract_interface in the repl,
Something like

/* components/clarity-repl/src/lib.rs */

/* ... */

#[cfg(feature = "wasm")]
#[wasm_bindgen]
pub fn get_contract_interface(name: &str) {
    let mut session = unsafe {
        match WASM_GLOBAL_CONTEXT.session.take() {
            Some(session) => session,
            None => return (),
        }
    };
    build_contract_interface(session. /* get analysis ... */);
    ()
}

I could try to dig a bit deeper over the weekend or early next week

@aulneau Is this still needed?

[aulneau]

Yes please

Just moved this issue in progress, it will be available in the v1.0.0 of the clarinet-sdk #1065

For context, @aulneau a new clarinet-sdk will be released next week on npm (release candidate 1). So if you're still interested, let's talk 🙌

[hugocaillard]

I marked this issue as fixed with #1151, because it's available in the clarinet-sdk.
More documentation to come soon.

import { initVM } from "obscurity-sdk";

async function main() {
  const vm = await initVM();
  const ci = vm.getContractsInterfaces();
}

More documentation to come soon.

@aulneau It might not be exactly what you were looking for so feel free to re-open or reach out to me
