Fix to open browser in WSL2

[kachick]

Fixes kachick/dotfiles#499

[kachick]

Isn't in podman-machine-default even if it is a WSL...

1! gh repo view -b 8a6ee98 --web
Opening github.com/kachick/dotfiles/tree/8a6ee98 in your browser.
exec: "xdg-open,x-www-browser,www-browser,wslview": executable file not found in $PATH

wslview is included in ubuntu-wsl
🤔

  (pkgs.writeShellApplication {
    name = "cross-platform-url-open";
    runtimeInputs = with pkgs; [ coreutils ];
    text = ''
      urlpath="$1"

      case "$(uname -s)" in
        Darwin)
          open "$urlpath"
          ;;
        *)
          # This condition maybe not enough for example podman-machine-default, but atleast worked on Ubuntu-22.04
          if [[ -e '/proc/sys/fs/binfmt_misc/WSLInterop' ]]; then
            explorer.exe "$urlpath"
          else
            xdg-open "$urlpath"
          fi
          ;;
      esac
    '';
    meta = {
      description = "open URL with considering WSL2";
    };
  })

But just using gh and wslview maybe simple
