Pack/unpack approach

[mgree]

Just load/unload data directly on the filesystem.

Progress indicator. https://docs.rs/indicatif/0.16.2/indicatif/

Multithreading? (Is that ever a performance win?)

Pack

BFS?

Unpack

Flag to follow symlinks, possibly even out of the root.

-i flag for prompting on weirdness.

Plan/milestones for @nad2040:

• install locally, get it working
• build locally
• read and understand format.rs
• unpack : json (or whatever) -> FS
  • be careful about overwriting things (inspired by tar flags)
  • write tests as you go (maybe a separate directory, same strategy)
• pack
  • be careful following symbolic links and moving outside of the directory tree (cf. tar or find)
  • loop detection
  • write tests as you go (start integrating, i.e., test pack and unpack together)

Long term goals:

• pack/unpack executables which support (nearly) identical CLI options
• tests work the same (mutatis mutandis)
• round trip property
• write tests comparable to jq
• microbenchmarks vs. ffs and vs jq (and vs gron?)
