.add_or_update_account(data_dir, username, password, characters = []) ⇒ Boolean

Note:

For existing accounts:

  • Password is always updated
  • Characters are merged (existing preserved, new ones added if not duplicates)
  • Existing character metadata (favorites, custom settings) is preserved
  • Duplicate detection uses normalized char_name + game_code + frontend + custom_launch
Note:

For new accounts:

  • Account created with normalized username (UPCASE)
  • Characters added with normalized names (Title case)

Adds or updates an account with password and optional characters Normalizes account and character names for consistent storage When updating existing accounts, merges characters to preserve existing metadata (favorites, etc.)

Parameters:

  • data_dir (String) —

    Directory containing entry data

  • username (String) —

    Account username (will be normalized to UPCASE)

  • password (String) —

    Account password

  • characters (Array<Hash>) (defaults to: []) —

    Optional array of character data hashes (will be normalized to Title case) Character hash format: { char_name:, game_code:, game_name:, frontend:, custom_launch:, custom_launch_dir: }

Returns:

  • (Boolean) —

    True if operation was successful

.update_launch_settings(data_dir, username, char_name, game_code, old_frontend:, custom_launch:, frontend: old_frontend) ⇒ Boolean

Reassigns exactly one saved entry without changing account credentials, favorites or per-entry custom launch settings. Rejects stale selections and duplicate destinations rather than editing a different entry.

    saved entry directory

  • username (String) —

    account name

  • char_name (String) —

    character name

  • game_code (String) —

    game instance

  • old_frontend (String) —

    frontend of the selected entry

  • custom_launch (String, nil) —

    exact selected custom command

  • frontend (String) (defaults to: old_frontend) —

    new configured frontend identifier

Returns:

  • (Boolean) —

    whether the change was saved
