Summary of Changes
Hello @Silentely, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request focuses on refining core functionalities and improving the user experience through several targeted enhancements. It addresses how media files are named upon download, simplifies error handling in network operations, and ensures more robust interaction with Telegram chat IDs. Additionally, the example configuration has been cleaned up to provide clearer guidance for users.
Highlights
- File Naming & Media Handling: Improved filename generation for downloaded media by attempting to extract meaningful names from Telegram message media, falling back to a generic ID if a specific name isn't available.
- Error Handling: Simplified error propagation within the retry middleware by removing external error wrapping and returning the original error directly.
- Configuration: Updated and streamlined the
config.example.tomlfile, clarifying comments, removing outdated or less common examples, and reordering sections for better readability. - Telegram Integration: Enhanced the Telegram storage backend to correctly parse and handle Telegram channel/supergroup IDs, which often include a
-100prefix, ensuring proper peer resolution.

Hey @Silentely - I've reviewed your changes - here's some feedback:
- The chat ID normalization in storage/telegram/telegram.go feels convoluted—consider handling the “-100” prefix directly on the int64 or centralizing this logic to avoid round-trip string conversions.
- In retry middleware, removing errors.Wrap loses error context—consider wrapping the error again (e.g. with fmt.Errorf("retry middleware skip: %w", err)) to retain diagnostic information.
- The fallback in GenFileNameFromMessage duplicates the default naming logic; you could simplify by inlining the GetMediaFileNameWithId call and falling back directly in one expression to reduce branching.

The fallback to a generated filename is good, but the new logic may overwrite a valid filename with an empty string if GetMediaFileNameWithId returns an empty value without error.
Check that mname is not empty before assigning it to filename, or ensure GetMediaFileNameWithId never returns an empty string on success.

There is a mismatch between the storage name in the whitelist and the defined storage name.
The example should use the correct storage name to prevent user confusion or misconfiguration.

Returning the error directly without any context might make debugging harder. Consider adding some context to the error message, even if it's just a simple string indicating that the error occurred during a retry attempt.

The GetMediaFileNameWithId function might return an empty string or an invalid filename. It would be beneficial to add a check for this and fallback to the default filename generation if necessary. This will prevent empty or invalid filenames from being used.

The code parses the chat ID from a string, but it doesn't handle the case where the chat ID is already an integer. This could lead to unnecessary string conversions and potential errors. Consider checking if the chat ID is already an integer before attempting to parse it from a string.
chatID := t.config.ChatID
if chatID < 0 && strings.HasPrefix(convertor.ToString(chatID), "-100") {
after := convertor.ToString(chatID)[4:] // Remove "-100"
cid, err := strconv.ParseInt(after, 10, 64)
if err != nil {
return fmt.Errorf("failed to parse chat ID: %w", err)
}
chatID = cid
