Requirements:

• Python 3.7+ and depencencies:
  • pip install -r requirements.txt
• ProtoC

Usage:

python usage: tachibk-converter.py [-h] [--input <backup_file.tachibk | backup_file.proto.gz | decoded_backup.json>] [--output <output.json | encoded_backup.tachibk>] [--fork <mihon | sy | j2k>]

options:
  -h, --help            show this help message and exit
  --input, -i <backup_file.tachibk | backup_file.proto.gz | decoded_backup.json>
                        File extension defines whether to decode a backup file to JSON or encode it back
  --output, -o <output.json | encoded_backup.tachibk>
                        When encoding, TACHIBK or PROTO.GZ will additionally recompress the backup file
  --fork <mihon | sy | j2k>
                        Use backup schema from the following fork. Default: Mihon
  --dump-schemas        Dump protobuf schemas from all supported forks
  --convert-preferences
                        Convert preference values into human-readable format.
