2023-09-02 rtx-cli activate nu, or, how to source init scripts designed for nu, with nu

Google returned nothing so here's this.

Nu has no eval(), which means you have to pipe the init script to a file like so:
rtx-activate nu >> ~/.config/nushell/.rtx.nu

The nu equivalent of source in bash/zsh is just use, and it's used in the same way as source in bash/zsh
use ~/.config/nushell/.rtx.nu

put these at the end of your config file, below the last bracket (usually the end of the env block, but I don't remember)
