From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Recommend me a scripting language (lemmy.ml)

I've been looking around for a scripting language that:

  • has a cli interpreter
  • is a "general purpose" language (yes, awk is touring complete but no way I'm using that except for manipulating text)
  • allows to write in a functional style (ie. it has functions like map, fold, etc and allows to pass functions around as arguments)
  • has a small disk footprint
  • has decent documentation (doesn't need to be great: I can figure out most things, but I don't want to have to look at the interpter source code to do so)
  • has a simple/straightforward setup (ideally, it should be a single executable that I can just copy to a remote system, use to run a script and then delete)

Do you know of something that would fit the bill?

Here's a use case (the one I run into today, but this is a recurring thing for me).

For my homelab I need (well, want) to generate a luhn mod n check digit (it's for my provisioning scripts to generate synchting device ids from their certificates).

I couldn't find ready-made utilities for this and I might actually need might a variation of the "official" algorithm (IIUC syncthing had a bug in their initial implementation and decided to run with it).

I don't have python (or even bash) available in all my systems, and so my goto language for script is usually sh (yes, posix sh), which in all honestly is quite frustrating for manipulating data.

Realistically whatever problems you see in python will be there for any other language. Python is the most ubiquitously available thing after bash for a reason.

Also you mentioned provisioning scripts, is that Ansible? If so python is already there, if you mean really just bash scripts I can tell you that does not scale well. Also if you already have some scriptsz what language are they on? Why not write the function there?

Also you're running syncthing on these machines, I don't think python is larger than that (but I might be wrong).

Currently it's mostly nixos, plus a custom thing that generates preconfigured openwrt images that I then deploy manually. I have a mess of other vms and stuff, but I plan to phase out everything and migrate to nixos (except the openwrt stuff, since nixos doesn't run on mips).

I don't really need to run this specific synchthing-ID script except on my PC (I do the provisioning from there), but I have written scripts that run on my router (using busybox sh) and I was wondering if there is a "goto" scripting that I can use everywhere.
