r2 (WIP)

Moved to SourceHut

Usage

$ r2 --init

$ r2 --add name path # backup file

$ r2 -q file # quick add (uses filename as name)

$ r2 -d file # check if file differs from backup

$ r2 -r file 1 # restore file from backup

How it stores data

files are listed in ~/.r2/defs.json:

"test": {
    "path": "/tmp/test",
    "latest": 1,
    "generations": {
        "1": "4e1243bd22c66e76c2ba9eddc1f91394e57f9f83"
    }
}

$ cat ~/.r2/store/4e1243bd22c66e76c2ba9eddc1f91394e57f9f83 
test

TODO

• prevent collision in filename
• list files
• list history of individual file
• multiple storage locations
• all existing commands, but recursively on directories
• rm - remove from defs
• purge - remove all instances of file from store
  • how should past generations handle it?
• garbage collection
• store only latest x versions of thing
• status (all files diff)
• export history of file
• target symlinked outside

Future commands

r2 --list

r2 --list-backups file

# basic dotfiles management
r2 --link vimrc ~/.vimrc # the link is to a version of vimrc in .r2/store

# scripts
r2 --add-bin foo.py # adds foo.py to PATH
