HuJSON - "Human JSON" (JWCC)

The github.com/tailscale/hujson package implements the JWCC extension of standard JSON.

The JWCC format permits two things over standard JSON:

1. C-style line comments and block comments intermixed with whitespace,
2. allows trailing commas after the last member/element in an object/array.

All JSON is valid JWCC.

Visual Studio Code association

Visual Studio Code supports a similar jsonc (JSON with comments) format. To treat all *.hujson files as jsonc with trailing commas allowed, you can add the following snippet to your Visual Studio Code configuration:

"files.associations": {
    "*.hujson": "jsonc"
},
"json.schemas": [{
    "fileMatch": ["*.hujson"],
    "schema": {
        "allowTrailingCommas": true
    }
}]
