Not gp but I prefer rust to python and I'm itching to try that "just write your build scripts and stuff in rust too"

Sure the builds are slow and Python _kinda_ has static typing, but rust just has a lot of stuff I like and it's practical to install and use natively without learning all the jargon like venvs and eggs and wheels and which package manager and package manager manager (rye?) to use this year

I tried Python years ago and never got the motivation to push through that learning curve. I've used c++ a lot but it always required me to "keep my hands inside the ride at all times". Rust feels like it actually wants to be easy to use

The idea of using Rust for scripting is bizaar.

I can understand not wanting to use Python for everything, but I see the problem being the 'use it for everything' not the language choice.

Use the tool that excels at the job. There is no language that is good at everything.

Incidentally, this thing comes up a lot: Python vs Rust for scripts. I wrote a comparison four years ago:

And updated it six months later:

That's still how I'd do this task today.

Anyway, I don't think that Rust is always a great choice for scripting, but if you already know Rust, it's totally fine at it.

Same for C++ with a good options library and std::filesystem IMHO. You can kind of script with that. I did it and was surprised it did well for some of my engine tooling.

Not at all, I do the same.

[natsucks]

Rust is cool now. Python is not cool anymore.

[smallstepforman]

The current project I’m working on has tons of resource caches (for performance), with tons of non-owning pointers sharing cache references. I’d hate to do this in opinionated languages like Rust.

I think Python fell victim to the Peter Principle. It got promoted beyond its competence.

[germandiago]

Python does well for several reasons.

Some that come to my mind: its versatility binding native code and its easy-to-fit in your brain mental model for many tasks. The fact that you can script with Python without a compilation step also helped a lot to spread its popularity I think.

[rightbyte]

The way you define the entry point function is so bizarre I assume scripting was the original use case.

[germandiago]

Could be. But it also gives you the flexibility to set tests inside the module files.

[AnimalMuppet]

Having to use the wrong tool is not cool, ever. So I don't care how cool Rust is right now, I still am not going to use it for scripting.

[weinzierl]

Have you tried it? How would you know that Rust is the wrong tool.

I'm indifferent when it comes to Python vs Rust for scripting, but I'd take Rust over a shell script (of any variety) any day.

[AnimalMuppet]

There are many things I have not tried, ranging from Rust to heroin. "You don't know because you haven't tried it" is really bad epistemology.

It's also totally impractical. Rust isn't the only language I haven't tried; there are more than a thousand of them. I'm not using JOVIAL for scripting, or Fortran, or a bunch of others. No, I haven't tried any of those either. No, I'm not going to.

Turning specifically to Rust, I don't use it for scripting because it's not what I look for in a scripting language. It's compiled; I look for a language that doesn't have that extra step. It has the borrow checker; I don't write scripting code that needs that level of discipline and care.

In fact, most of my scripting is of the form "pick some bits out of a text file". For that, Perl is my tool of choice. Sure, other languages have regexes. None of them do it as cleanly and simply as Perl. (Note well: "clean" does not apply to the Perl syntax...)

For a single file script, you can avoid managing environments by using a nix shebang: https://github.com/NixOS/nixpkgs/blob/master/doc/languages-f...
