Andrew Chin (Nov 23 2022 at 02:31): Andrew Chin (Nov 23 2022 at 02:31):Hi all :wave: I'm playing with cargo-component for the first time, and I've created something with cargo component new and then cargo component build. I want to inspect the resulting wasm file, so I tried wasm-tools print on it, but I got this error:
Error: unexpected end-of-file (at offset 0x1e099d)
is this a known issue?
Peter Huene (Nov 23 2022 at 03:14):cargo-component is slightly out of date with the binary format (wasm-tools was updated late last week), I'm in the process of updating it now
Peter Huene (Nov 23 2022 at 03:15):if you use wasm-tools from just before this PR was merged, it should hopefully work around the issue.
Peter Huene (Nov 23 2022 at 03:16):i'm waiting on this other PR to merge and then I'll update cargo-component so that it works with the latest wasm-tools
Andrew Chin (Nov 23 2022 at 03:23):Thank you very much, Peter. I'll keep an eye on those PRs, and for your upcoming one that updates cargo-component
Peter Huene (Nov 29 2022 at 01:41):Hi @Andrew Chin . I've put up https://github.com/bytecodealliance/cargo-component/pull/41 which should update it to the latest component model spec (and thus work with the latest wasm-tools).
Peter Huene (Nov 30 2022 at 22:32):Hi @Andrew Chin. I just wanted to follow up and say the PR was merged, so if you update your cargo-component (note that there is a brekaing change with wit file contents: they need to now be wrapped in an interface <name> { ... } declaration), it should now work with current wasm-tools. Thanks for your patience!
