EDIT: Draft. Cosmos API is not published yet with this change (https://github.com/staffpad/cosmos/pull/1199). Message me on slack for more info :)

The MuseSounds catalogue is fetched on every launch by POSTing a GraphQL document. This switches it to a GET against a server-side persisted operation, so the response can be cached.

  • locale moves from string interpolation in the query text into a GraphQL variable
  • endpoints move to customers-api.musehub.com / customers-api-dev.musehub.com (Cloudflare-fronted)
  • request becomes GET ?pqId=musescore-studio-sounds-page-v1&variables={"locale":"..."}

The response payload is unchanged, so parseSounds() is untouched. The old POST path continues to work, so existing releases are unaffected.

Move the locale into a GraphQL variable, point at the customers-api hosts,
and request the operation by persisted id over GET so the response can be
served from cache instead of hitting the API on every launch.

📝 Walkthrough

Walkthrough

MuseSounds now selects MuseHub production or development GraphQL endpoints according to test mode. The catalog request now uses a GET URL with pqId and compact JSON variables query parameters. Locale values remain based on the system BCP 47 language and territory codes. The previous POST request body construction and upload were removed.

Qt QLocale bcp47Name territoryToCode documentation QLocale en_GB

💡 Result:

In Qt, the QLocale class provides methods for managing locale-specific settings [1]. QLocale::bcp47Name The bcp47Name method returns the locale name formatted according to IETF BCP 47 (RFC 5646) [2]. By default, it uses a hyphen as a separator, but since Qt 6.7, you can specify an optional separator [2]. Example: QLocale locale("en_GB"); QString bcp47 = locale.bcp47Name; // Returns "en-GB" QLocale::territoryToCode The territoryToCode method is a static function that converts a QLocale::Territory enum value into its corresponding CLDR (Common Locale Data Repository) territory code (e.g., "GB" for the United Kingdom) [3]. Example: QString code = QLocale::territoryToCode(QLocale::UnitedKingdom); // Returns "GB" QLocale("en_GB") You can initialize a QLocale object using the "en_GB" string [4]. This is commonly used in Qt applications to force or set a specific locale for formatting dates, times, currencies, and other locale-dependent data [4][5]. For example, to set the application's default locale to British English: QLocale::setDefault(QLocale("en_GB")); [5][6] Top results: [1][2][3][4][5]

Use bcp47Name() as the complete locale value.

For QLocale("en_GB"), bcp47Name() returns en-GB. The current code therefore sends en-GB-GB, which is not a valid BCP 47 locale tag. Set localeStr to locale.bcp47Name() and add coverage for en_GB.

@DominicMaas, thank you for confirming this from the API calls. The locale value should use QLocale::bcp47Name() without the appended territory code.
