DAM - A file shuffler

Bridges the gap for a one way file sync between devices that have different folder structures.

Functionality

• Dam is designed to help syncing photos between my phone and my server
  • The two devices use radically different folder structures
  • The phone stores all photos in the same level (root of synced folder)
  • The server stores photos using the following layout: (photodir)/YYYY/MM/(all photos for said year and month)
  • Dam must take all the photos (and videos) in the source directory and hardlink the files to the server's photodir, using the correct file layout
• Dam takes two folder paths as command line arguments
  • One is the synced phone folder
  • The other is the destination
• Dam parses the EXIF data of the various files to determine file dates
• Dam uses Linux filesystem watching, to process new images in the synced folder
• Dam checks the destination before hardlinking the file.
  • If the file already exists, it check if it is an hardlink
  • If it's not an hardlink it checks if the file sizes differ.
  • If the file sizes differ, it renames the the old file, adding a suffix. It then creates the hardlink

Usage

go run ./cmd/dam

External libs:

• cobra: cli parsing
• fsnotify: filesystem watching
• go-libexif: exif parsing

TODO

• Concurrency
• Split into sync and watch commands
• Configurable Exiftool path
• Config file
