Add json schema for `fly.toml`

[remorses]

With tools like Even better toml (VScode extension) you can add auto completions and validation to toml files by using adding a json schema to a file type

Having a json schema file link in the docs would be super helpful

Then you could add the following config to VScode to have autocompletions in fly.toml

{
    "evenBetterToml.schema.associations": {
        ".*fly\\.toml": "https://fly.io/fly_toml.schema.json"
    }
}

You could also add your schema to this directory and fly.toml files would automatically get validation and auto completion to anyone with Even better toml installed

Thanks! I was just thinking about how to go about this. I'm giving it a try now. Are you able to use local file:// references in the config? I haven't gotten that to work yet for debugging.

I got a poc working adding a .vscode/settings.json with

{
    "evenBetterToml.schema.associations": {
        ".*fly\\.toml": "file:///Users/morse/Documents/GitHub/docs-from-notion/fly_toml.schema.json"
    }
}

Try editing the file to start the extension or run "Reload window"

Nice, that works. Are you interested in contributing a full schema?

[remorses]

If you already have a kitchen sink fly.toml with all the fields used you can use a tool like quicktype to generate the schema from the json

Also, for the regex it would be better to use .*fly(.*)?\\.toml to also match fly.production.toml

Started one out here. So far it works pretty well. Thanks for the tip.

This was merged into Taplo, so is now available automatically by installing Even Better TOML.
