$ show aydinnyunus/exifLooter
The exifLooter is a command-line application written in Go that extracts EXIF metadata, particularly GPS coordinates, from image files. It relies on the external exiftool command-line utility to perform the actual metadata extraction and provides a user-friendly interface for analyzing single images, directories of images, or images downloaded from URLs via stdin. The tool also offers functionality to remove all metadata from images and to generate OpenStreetMap URLs from GPS coordinates found in images. The architecture is a standard CLI tool built using the Cobra library for command parsing and the fatih/color library for colored terminal output. The main entry point is in main.go, which delegates to the command defined in cmd/root.go. The core functionality involves invoking exiftool via os/exec, parsing its output to detect GPS-related tags, and presenting the results with color-coded warnings when geolocation data is detected. Additional features include downloading images from URLs (with validation of content type) for batch processing in a pipe mode. While the tool fulfills its intended purpose, the codebase exhibits some areas for improvement: the pipe mode's image validation step is inefficient (rescanning the entire directory for each download), the OpenStreetMap URL generation function incorrectly handles southern and western hemisphere coordinates, and there is a lack of automated tests. Despite these issues, the project is actively maintained with recent commits and uses dependency management via Go modules.
The LLM identified 2 files worth highlighting for reuse:
The getFileExtensionFromUrl function extracts the file extension from a URL. It is a self-contained, pure function that handles edge cases (like URLs without extensions) and relies only on the standard library. It can be easily reused in any project that needs to parse URLs for file extensions.
The standardizeSpaces function normalizes whitespace in a string by splitting on whitespace and rejoining with a single space. It is a trivial but useful utility that is free of bugs and has no dependencies, making it safe to reuse in any project.
