Refactored and modernized version of textfile-exporter #23
Description
I’ve been using textfile-exporter and found it very useful. To better fit modern environments and improve maintainability, I have performed a significant refactor of the codebase.
I have published the updated version here: https://github.com/SckyzO/textfile_exporter
Major Improvements Over the Original
This version is more than just a fork; it's a complete overhaul with significant enhancements:
- Enhanced Security: Hardened the external command execution to prevent potential command injection vulnerabilities (gosec G204) that were present in the original version.
- Modern Project Structure: Adopted a standard Go project layout (cmd/, internal/) for better organization, easier maintenance, and clearer contribution paths.
- Improved CLI: Integrated the kingpin library for a more powerful and user-friendly command-line experience with detailed help text and better flag support.
- Full Build Automation: Implemented a Makefile and a complete GoReleaser workflow for automated, multi-platform builds and releases with embedded version information.
- Better Code Modularity: Refactored the entire codebase to separate concerns into distinct packages (collector, scanner, logger), resulting in a cleaner, more robust, and more maintainable application.
- Recursive Scanning: Added the ability to recursively scan subdirectories for .prom files, enhancing flexibility for metric file organization.
- Comprehensive Error Reporting: Introduced detailed Prometheus metrics for file scanning and parsing errors, providing better observability and troubleshooting capabilities.
