JSON schema for `spin.toml`?

[radu-matei]

I would really like to get some documentation and completion support when writing a spin.toml file, and apparently, the Even better TOML VS Code extension lets you do that:

There is a configuration key a user would need to add to get schema support, but I think this would be a really good improvement to the user experience for writing spin.toml files.

and indeed fermyon/spin-vscode#2

Is this work still in progress?

If anyone wants to play, here's a schema auto-generated from Master:

Taplo crashes like crazy with the anyOf that's generated with the old/new schema version enum, so it's better to remove that by hand:

#:schema https://gist.githubusercontent.com/cardoso/03613b5b53ca005fd91d869d3e78f000/raw/66e533898e1cd12c61ce6eab8d99678a75f2a8b8/spin.toml.schema.simple.json

name = "spin-sandbox-rust"
spin_manifest_version = "1"
version = "1"
[trigger]
    http = { base = "" }


[[component]]
    id = "spin-sandbox-rust"
    source = "file"
    trigger = { route = "" }

Probably good to keep in mind for #1396 .

Ooh, thanks for the schema, @cardoso!

@itowlson — is this something we can use for the VS Code extension?

[cardoso]

@radu-matei yep, just some superficial tweaks to the manifest models to fix some gaps in the hints and it should be good.

You can use the link @itowlson posted above: https://taplo.tamasfe.dev/configuration/developing-schemas.html#publishing

I remember testing that a few months ago and it worked pretty well just by adding the contribution.

I'll see if I can push what I have locally. Would this be better as a build script or a command in the CLI?

[radu-matei]

I think a build script would work well here.

Thoughts, @itowlson ?
