Recommend me a scripting language

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.

Perl or python for things likely to already be there. Maybe ruby or PHP if you must. I used to work in groovy a lot but I think it requires the JVM

Perl requres the perl interpreter and python requires a python interpreter. Why is it bad that groovy also needs a vm?

I don’t know if it matches your desire for easy install of small disk space, but it might make up for it in other arenas - Ruby is my new-found love when making simple scripts. Being able to mostly emulate the shell integration that bash has by just using backticks to call a shell command is the killer feature in my book.

Quickly came to write “AWK!!!” but yeah… you don’t want its superiority… 😜

My go to for most of what you mention is Go, but that’s obviously a compiled language and not for scripting. Or is it - What do you think about github.com/traefik/yaegi, which provides an interpreter and REPL for Go? It would let you use a performant and well documented language in a more portable scripting way, but not preclude you from generating statically linked binaries if and when that’s convenient.

Why are you making it hard on yourself? apt/dnf install a language to use and use it.

Why not give (Common)LISP a try?

Python is what you want. You can install it on just about any system.

Other than that maybe Lua but that will be hell.
