Nushell

• Still quite new, lots of little issues and incompatabilities
  • Can function just fine as a login shell, but be aware of this
  • Main thing to be aware of that many installers/tutorials that provide shell commands assume a POSIX-compliant shell, which nu is not
• Nix doesn't work
• When set as a login shell, it won't load any config/env when executing a command directly via SSH (e.g. ssh hostname '$env.PATH')
  • nushell/nushell#10219
  • Hacky workaround that I'm using in my own config:

    # Executes a shell command on a remote machine using a nu login shell.
    #
    # TODO: This is a workaround; once there's a fix in nu this can be dropped.
    export def ssh-exec [host: string, cmd: string --tty (-t), ...rest: string]: nothing -> string {
        let macNu = "/opt/homebrew/bin/nu"
        let linuxNu = "/home/linuxbrew/.linuxbrew/bin/nu"
        ssh $host ...$rest $"^$\"\(if \('($macNu)' | path exists) { '($macNu)' } else { '($linuxNu)' })\" -l -c '($cmd)'"
    }
    

• As seen above, highlight.js does not support nu highlighting
  • TODO: open GH issue
• Excellent for playing around with data
  • POSIX shells don't come close
  • Needs some proper graphing tools
    • TODO: either open GH issue or make/find something

Nix

• Need a custom env setup
  • Currently using one based on the GH issue is the best workaround
  • NixOS/nix#9813
• nix-darwin doesn't work at all
  • TODO: GH issue needs opening
