- Introduced a new tool to find log processing times from log files.
- Added functionality to display top files with the longest processing times.
- Implemented average processing time calculation across all files.
- Included necessary dependencies like chrono, regex, and clap for functionality.
- Created a new Cargo.toml for the 'find_log_processtime' package.

I'm getting to work. See my steps and track my cost here.

Thank you for this contribution! I've reviewed the new log processing time analysis tool. The implementation is generally good with clear structure and error handling. Here are some suggestions for improvement:
Strengths
- Good use of error handling with
anyhow - Clear command-line interface using
clap - Progress bar implementation for better UX
- Proper handling of ANSI escape codes
- Good separation of concerns in functions
Suggestions for Improvement
- Consider adding unit tests for core functionality
- The codebase would benefit from more documentation, especially for public functions
- Some constants could be extracted for better maintainability
- Consider adding input validation for the number of files in the
Topcommand - The timestamp format could be made configurable for different log formats

Consider adding more detailed documentation about the expected log file format and examples of usage.

Adding documentation with an example helps users understand the expected timestamp format.
| // Timestamp format: milliseconds (3 digits). | |
| /// Format string for parsing timestamps in log files | |
| /// Example: "2024-02-20 10:15:30.123" |

Add validation to ensure num_files is greater than 0.

| if num_files == 0 { | |
| anyhow::bail!("Number of files must be greater than 0"); | |
| } |

Consider creating a custom type for the return value instead of using a tuple. This would make the code more maintainable and self-documenting. For example:
struct ProcessingTime {
duration: f64,
filename: String,
}| version = "0.1.0" | ||
| edition = "2021" | ||
|

The dependencies look good and up-to-date. Consider adding thiserror for custom error types if you plan to expand the error handling.
- Introduced a new `ProcessingTime` struct to encapsulate duration and filename. - Modified `compute_diffs` function to return a vector of `ProcessingTime` instead of tuples. - Updated sorting and printing logic to utilize the new struct for clarity. - Improved code readability and maintainability.
