fli

Thing I stumbled upon: I added boolean argument and if statement inside sort_unstable_by closure: ``` //from |&a, &b| compare(a, b) //to |&a, &b| if is_reverse { compare(b, a) } else { compare(a, b) } ``` I expected binary to grow slightly, but actually it became ca 1KB smaller. I dug into with bloaty and found that the reason is: quicksort fn became 980 bytes smaller. Still not sure why. Inlining looks same, quicksort just has fewer instructions. target: arm-unknown-linux-gnueabihf details: https:// pastebin.com/qJdTw49n commit: https://github.com/tracyspacy/fli/commit/a87a98be77cc1972a53e6399716a227d1135e76b

Why? I have access to my raspberry pi zero via ssh only. As for me it is hard to differentiate types of files etc based on colors, I needed something more readable and clear like picture/icon or emoji as I ended up with etc. And I decided to build fli and since ls is obviosly preinstalled on almost any machine, the second requirement for fli as a complimentary tool, is to be tiny. Readability: Nice readability thanks to use of emojis ( and ) instead of text coloring. Size: Since rust std contributes heavily to binary size, this project is no_std + libc Current binary size: M-series Mac 51KB , rpi zero 18KB. Display options: `fli` : short (name and type) not sorted output - direct stream, no heap allocation `fli -s`: short (name and type) sorted by name output - uses heap allocation `fli -l`: long (name, type, metadata ) not sorted output

Initial release of FLI - really tiny and fast (like a ) 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 ( and ) instead of text coloring - Written in no_std rust + libc. repo: https://github.com/tracyspacy/fli
