So any other #nushell enthusiasts out there? It's like rust, functional programming and bash had a beautiful baby and I love it so much. The expressiveness and helpful error messages are a godsend and let me actually compose useful shell pipelines without googling everything. 🧵 - ThreadSky

My daily driver is still fish due to just how user friendly it is, but whenever I have to do any data crunching or scripting, it's my go-to. I even implemented my own runNushellScript and co on Nix before I realized they were already a thing in the standard library 🙃

when you have to do scripting or data crunching i honestly dont see any point in not using an actual programming language

trustmeim.gay•71 days ago

Understandable, I think it fits middle ground tasks like "times users committed to this git repo whose names start with L in descending order". I've written pretty simple commands like that in a minute right in the shell, I'm sure bash wizards could too but I find it way easier to grok and reason.

It's also super useful as a universal converter of sorts, pretty much a jq on steroids.
Yaml to json? `open file.yml | to json`
JSON to CSV? `open file.json | to csv`
And so on

It's on my list to try, but I haven't yet!

What's like the top 2-3 best things about it? I pretty much just run `cargo test` and `cargo run` to be fair

1) Functional style, lends itself well to pipes and makes it easy to compose and reason about.
2) Structured data, pipes pass around "objects", not just text. Makes operating on them easier.
3) Great UX, the error messages are extremely good, pretty much Rust-style since you're used to that.

Just a super solid experience all around, and basically what I always wanted shells to be. I'm terrible at remembering shell commands and how to chain them so having the familiar map/take/reduce and whatnot means it's instantly familiar.

iolivia.me•71 days ago

Nice! That's an awesome list, thank you! I will add it to the todo list

baxuru.bsky.social•71 days ago

🙌 ooh yes. i love it too

trustmeim.gay•71 days ago

Oh I see you've done some AoC on nu, very nice! Things like your screenshots are a prime example of how clean and readable nu code looks imo.

baxuru.bsky.social•71 days ago

yeah it's really just to get the nu-muscle memory going a bit... and fun, oddly satisfying

I’m slowly trying to learn it. I have like 30 years of POSIX (csh and bash) I need to unlearn though. :)

trustmeim.gay•48 days ago

Haha valid, I still mainly use fish for the user friendliness anyway. Not POSIX either ofc but definitely a tad closer.
The cool thing about shells is you can just drop in and mess around now and then, it's what I've been doing and it's been more than enough to impress :)

fortran95.bsky.social•48 days ago

Yeah. Fish causes the same issues. I should like it more, but I have so many plugins now my zsh is close to fish. :) nu is so different my brain doesn’t think it’s posix like fish sort of is close to

trustmeim.gay•48 days ago

I hear you, I just happen to be the kinda person who got tired of picking zsh plugins and just uses fish with a couple options changed so basically the exact target audience xD

fortran95.bsky.social•48 days ago

Yeah. At some point I might just get there. I’ve already moved to starship, so at least my prompt is the same everywhere. :)

jonahplusplus.dev•70 days ago

I tried it when testing NixOS but then went to Fish and Arch instead. It's really cool, but unnecessary for most devs IMO.

jonahplusplus.dev•70 days ago

Especially since when I want to write a script for data processing, I'm probably going to use Python or Bash for portability.

trustmeim.gay•70 days ago

That's fair, I find nu really shines in the space between trivial and complex enough I'd reach for a full language. Shaping up something you get from a command, converting between text formats, quickly grabbing some stats and whatnot.

nelind.dk•71 days ago

I've been meaning to try it out for ages! Seems really interesting.

trustmeim.gay•71 days ago

I can't recommend it as a full daily driver just yet but as soon as someone makes a plugin with fish-like qol features it'll be a beast! Still very worth it for piping data around or just practicing functional coding imo.

venatio.dev•12 days ago

i've heard of this before but after seeing it mentioned elsewhere on here i've decided to give it a proper tryout. seems cool, but just starting. i'll see how i feel in a week!

trustmeim.gay•12 days ago

Hey gl, hope you have fun! If nothing else, having it as a secondary shell for handy data crunching is cool :)

venatio.dev•12 days ago

every time i need to grep something i curse myself for not studying the traditional command line utilities. this seems even better tho.

trustmeim.gay•12 days ago

I have experience with them but I can never quite recall which arcane flag combination is the one I need, never mind how to make them all play nice together. Nushell just gives me a consistent way to manipulate stuff.
