tbext-manifest-schema

• JSON Schema for Thunderbird extension.
• This package does not work much as addons-linter does for Firefox Addons.
• status: raughly O.K.

how to use

As for VS Code's workspace config, such as foo.code-workspace

  {
    "settings": {
      "json.schemas": [
        {
          "fileMatch": ["*/path/to/manifest.json"],
          "url": "./path/to/tbext.min.json",
        }
      ]
    }
  }

how to make JSON Schema file

$ npm run build -- --mozilla-repo /path/to/mozilla --comm-repo /path/to/comm

(At 2019-04-11) You will see following error messages, but no problem.

> tbext-manifest-schema@0.2.0 build X:\path\to\tbext-manifest-schema
> node build.js "--mozilla-repo" "x:/repository/mozilla-central" "--comm-repo" "x:/repository/mozilla-central/comm"

error on optional: default_locale

Known Issue

// comment

One-line comment is allowed (only Firefox?), but I can not specify it in the JSON Scheme.

default_locale

For default_locale, to be mandatory or prohibited is conditional. Its condition cannot be described in this JSON Schema, because it involves the existence of _locales directory.

Warning "Matches multiple schemas when only one must validate"

VS Code's validator does not discriminate objects inside oneOf and result in that warning on background or so.

  {
    "two different subschema cannot be discriminated."
    "background": {
      "oneOf": [
        {
          "type": "object",
          "properties": {
            "page": {
              "type": "number"
            }
          }
        },
        {
          "type": "object",
          "properties": {
            "scripts": {
              "type": "array",
              "items": {
                "$ref": "#/definitions/ExtensionURL"
              }
            },
            "persistent": {
              "$ref": "#/definitions/PersistentBackgroundProperty"
            }
          }
        }
      ]
    }
  }

c.f. Combining schemas — Understanding JSON Schema 7.0 documentation

format may result in error or warning

JSON Schema Document says "JSON Schema implementations are not required to implement this part of the specification, and many of them do not".

As for VS Code, validator seems to do nothing for format.

So, this schema currently does nothing for it, and non-standard format such as strictRelativeUrl remains in.

c.f. string — Understanding JSON Schema 7.0 documentation

Note for implementation

$id does not work

JSON Schema Document says "This functionality isn’t currently supported by the Python jsonschema library".

I do not know about VS Code's JSON Schema Validator, but anyway it does not handle $id.

'match mode (?i)' of RegExp

For the case of string type, it can have pattern keyword. JSON Schema does not handle it, and that results in RegExp error.

  This says "Refer to the documentation and examples at the JSON Schema site for details on how these items are defined in a schema". But some items in API schema (e.g. choices) does not match with specs of all versions like 0.4 or 0.7 currently (2019 March) on that site.

  • Change: content_security_policy has version specs(max_manifest_version and min...), but currently this Schema does not handle them. Maybe draft 7's if-then-else resolves this. 1696043
  • Note: At mozilla-central, chrome_settings_overrides - search_provider.favicon_url can be "strictRelativeUrl" on ManifestV3. This has no effect because JSON Schema meta-spec (draft 7, and its validators) does not know Mozilla's "format"s. And on comm, there is its own chrome_settings_overrides.json, so no effect. 1697059
