how can we add devbox global path to nushell?

What problem are you trying to solve?

how does eval "$(devbox global shellenv)" translate for nushell?

What solution would you like?

an example on how to configure devbox global in nushell

Alternatives you've considered

I'm not sure there's a really easy way to translate the script, since nushell expects variables in a different format than what devbox global shellenv exports.

You might want to look into the nu plugin bash_env, which can evaluate a bash environment and then load it into your nushell? The plugin is described here: https://github.com/tesujimath/nu_plugin_bash_env

@vtmocanu Hi, were you able to solve this?

I'm also frustrated by this

Hi, I was able to temporarily solve this by putting this snippet into config nu:
