A CLI tool to parse, filter, and analyze log files using saved formats, custom regex, or AI-based format detection. Works even with unknown or complex log structures.

• Saved Format: Use previously saved regex patterns.
• AI Mode: Sends sample log lines to Gemini API to generate a regex and timestamp format.
• Custom Regex: User provides a Python regex with named groups.

• Reads the log file line by line.
• Applies regex to extract timestamp, level, source, and message.
• Filters can be applied by level, date range, or keyword search.

• Save AI-detected or custom formats for future use.
• List or delete saved formats.

# AI-based detection
python main.py -i server.log --use-ai

# Custom regex
python main.py -i server.log --custom-regex "(?P<timestamp>.*?) - (?P<level>INFO|ERROR) - (?P<message>.*)" --timestamp-format "%Y-%m-%d %H:%M:%S"

# Use saved format
python main.py -i server.log --use-format apache

• AI mode requires GEMINI_API_KEY environment variable.
• First 20 lines of the log are used for AI analysis.
