That's why I use nushell. Very convenient for writing scripts that you can understand. Obviously, it cannot beat Python in terms of prototyping, but at least I don't have to relearn it everytime.
So the alternative is:
I am of the opinion that production software shouldn't be written in shell languages. If it's something which needs to be redistributed, I would write it in python or something
On a more serious note, NOTHING with more than a little complexity should be written in shell scripts imo. For that, Python is the best, primarily due to how fast it is to prototype stuff in it.
I tend to write anything for distribution in Rust or something that compiles to a standalone binary. Python does not an easily redistributable application make lol
Yeah but then you either need to compile and redistribute binaries for several platforms, or make sure that each target user has rust/cargo installed. Plus some devs don't trust compiled binaries in something like an npm package
For a bit of glue, a shell script is fine. A start script, some small utility gadget...
With python, you're not even sure that the right version is installed unless you ship it with the script.
I try to write things to be cross-platform; with node builds, I avoid anything using shell scripting so that we can support Windows builds as well. As such, I usually write the deployment scripts in Node itself, but sometimes python if it's supported by our particular CI/CD pipeline
I keep forgetting windows exists.
Most common development platform in the world
I quit using it in the WfW days and never looked back.
You haven't used windows in like 30 years? It's quite different now lol
Maybe. I'm fine with my Linux machines though.
That's why docker exists :D
Ruby and calling bash like this
Nu is great. Using it since many years. Clearly superior shell. Only problem is, that it constantly faces breaking changes and you therefore need to frequently update your modules.
Not a problem for me in Nix, seems like a skill issue ~/j~
They’ve slowed down with those a bit recently, haven’t they?
Yesterday, I upgraded from
0.101.0to0.102.0anddate to-tablewas replaced equally (actually better) withinto record, however it was not documented well in the error. Had to research for 5 to 10 minutes, which does not sound much, but if you get this like every second version, the amount of time adds up quickly.Actually had been deprecated beforehand, you should have gotten a warning. The deprecation cycle certainly is quite short, I'm still on 0.100.0, If I were to upgrade now I'd jump the version with the warning.
Yes, I switched to an older version and there was the warning. However, there was no warning on
0.101.0whatsoever, so upgrading just one patch version broke my master module.Sometimes, I skip some versions, so I am certain, that I jumped from <
0.100.0straight to0.101.0and here we are, without any deprecation warning.Not really. They've been on the stabilising path for about two years now, removing stuff like dataframes from the default feature set to be able to focus on stabilising the whole core language, but 1.0 isn't out yet and the minor version just went three digits.
And it's good that way. The POSIX CLI is a clusterfuck because it got standardised before it got stabilised.
dd's syntax is just the peak of the iceberg, there, you gotta take out the nail scissors and manicure the whole lawn before promising that things won't change.Even in its current state it's probably less work for many scripts, though. That is, updating things, especially if you version-lock (hello, nixos) will be less of a headache than writing
shcould ever be. nushell is a really nice language, occasionally a bit verbose but never in the boilerplate for boilerplate's sake way, but in the "In two weeks I'll be glad it's not perl" way. Things like command line parsing are ludicrously convenient (though please nushell people land collecting repeated arguments into lists).Fully agree on this. I do not say, it's bad. I love innovation and this is what I love about Nushell. Just saying, that using it at work might not always be the best idea. ;)
We have someone at work who uses it and he's constantly having tooling issues due to compatibility problems, so.. yeah.
I'm sure it's fine for sticking in the shebang and writing your own one-off personal scripts, but I would never actually main it. Too much ecosystem relies on bash/posix stuff.
