Initial release of FLI - really tiny and fast (like a ๐Ÿชฐ) directory listing tool.

Initial Why: need some easy readable ls like tool for rpi to use via ssh.

Current Why: check if with Rust one can build core utils like tools faster and smaller.

  • Size:

18K - RPI ZERO W

51KB - Mac

  • Default mode streams readdir() => stdout with zero heap allocation.

  • Nice readabilty thx to (๐Ÿ“„ and ๐Ÿ—‚๏ธ) instead of text coloring

  • Written in no_std #rust + libc.

"-C", "link-arg=-lstdc++", "-C", "link-arg=-lsupc++", "-C", "link-arg=-lgcc_s"

good catch!

rustix - take a look, thx.

no_std was my deliberate choice. -C prefer-dynamic - it feels that it may be a more fragile option and add some hassles with cross compiling - something like error while loading shared libraries: ... so I have to provide libstd.so as well together with binary to rpi .. where is the gain?
