For nim, you could use something like nimcr (https://nimble.directory/pkg/nimcr). You put a shebang in your script `#!/usr/bin/env nimcr` and then call it like a normal script.

eg:

  $ code script.nim


  #!/usr/bin/env nimcr
  echo "hello world"


  $ ./script.nim
  hello world

edit:

There's also the possibility of using nimscript, using nim e. It works similarly but you'd change the shebang line to something like

  #!/usr/bin/env nim e --hints:off
