Here's a Python implementation of a backup file decoder based on the provided Kotlin files. This implementation assumes that the backup file is in Protocol Buffers format and uses the `protobuf` library to decode it.
```python
import gzip
import protobuf
# Define the protobuf message classes
BackupManga = protobuf.Descriptors.BackupManga
BackupChapter = protobuf.Descriptors.BackupChapter
BackupCategory = protobuf.Descriptors.BackupCategory
BackupTracking = protobuf.Descriptors.BackupTracking
BackupHistory = protobuf.Descriptors.BackupHistory
BackupSource = protobuf.Descriptors.BackupSource
BackupPreference = protobuf.Descriptors.BackupPreference
BackupSourcePreferences = protobuf.Descriptors.BackupSourcePreferences
Backup = protobuf.Descriptors.Backup
def decode_backup(backup_file_path):
with open(backup_file_path, 'rb') as f:
content = f.read()
# Check if the file is gzipped
if content[:2] == b'\x1f\x8b':
content = gzip.decompress(content)
# Parse the protobuf message
backup = Backup.FromString(content)
# Process the backup data
print(f"Number of manga: {len(backup.backupManga)}")
for manga in backup.backupManga:
print(f"Manga: {manga.title}")
for chapter in manga.chapters:
print(f" Chapter: {chapter.name}")
print(f"Number of categories: {len(backup.backupCategories)}")
for category in backup.backupCategories:
print(f"Category: {category.name}")
print(f"Number of tracking entries: {sum(len(manga.tracking) for manga in backup.backupManga)}")
for manga in backup.backupManga:
for tracking in manga.tracking:
print(f"Tracking: {tracking.title}")
print(f"Number of history entries: {sum(len(manga.history) for manga in backup.backupManga)}")
for manga in backup.backupManga:
for history in manga.history:
print(f"History: {history.url}")
print(f"Number of sources: {len(backup.backupSources)}")
for source in backup.backupSources:
print(f"Source: {source.name}")
print(f"Number of preferences: {len(backup.backupPreferences)}")
for pref in backup.backupPreferences:
print(f"Preference: {pref.key} = {pref.value}")
print(f"Number of source preferences: {len(backup.backupSourcePreferences)}")
for source_prefs in backup.backupSourcePreferences:
print(f"Source preferences for {source_prefs.sourceKey}:")
for pref in source_prefs.prefs:
print(f" {pref.key} = {pref.value}")
if __name__ == "__main__":
backup_file_path = input("Enter the path to the backup file: ")
decode_backup(backup_file_path)
```
This program defines the Protobuf message classes based on the Kotlin classes provided. The `decode_backup` function takes the path to the backup file as input, opens the file, decompresses it if it's gzipped, and parses the Protobuf message using the `protobuf` library.
After parsing the backup data, the function processes and prints the various components of the backup, such as manga, chapters, categories, tracking entries, history entries, sources, preferences, and source preferences.
Note that you'll need to have the `protobuf` library installed to run this program. You can install it using `pip install protobuf`.
