nushell: `cd` not working

[Schweber]

I am using broot 1.32.0 with nushell 0.89.0 and applied the argument expansion to the br shell function from #821

However, :open_leave doesn't work for me in nushell. I've set { key: "enter", execution: ":open_leave" } but if i press enter on a file/directory in broot, i'm back in the terminal without the folder having changed. Running pwd confirms this, so it's not a problem of the prompt not being updated.

Using { invocation: "cd", key: "enter", execution: "$SHELL", set_working_dir: true } "works" but this launches an additional instance of nu with the given folder so it's not a good workaround.

What could be the reason for this?

[Schweber]

Just to be sure: you launch br, not broot ?

Yes, just double checked.

[Denys Séguret]

:open_leave isn't supposed (or able) to change the current directory of the opening shell.

Try with this:

{
    key: enter
    internal: open_leave
    apply_to: file
}
{
    key: enter
    external: "cd {directory}"
    from_shell: true
    apply_to: directory
}

Unfortunately, it's not working. I had { key: "enter", from_shell: true, execution: "cd {directory}", set_working_dir: true } for some time as a workaround for fish but in nu it's not working at all.

Is there a way to get a verbose output of broot to see why it fails? I found no such cli option...

Yes, there's a log: https://dystroy.org/broot/community/#log

Thanks, it says this:

You don't have other verbs than the one I proposed mapped to the enter key ?

I'll have a deeper look and try on nushell but it won't be before a few days.

[Schweber]

No, no further mappings to enter, just the ones you posted in this tread.

I just added this to be sure:

{
    key: Tab
    internal: open_leave
    apply_to: file
}
{
    key: Tab
    external: "cd {directory}"
    from_shell: true
    apply_to: directory
}

but it also is not working for me.

I updated to nushell 0.90.1 and broot 1.34.0 and reinstalled the br shell function but the problem is still there

[Schweber]

I'm now on nushell 0.91. and broot 1.36.0 and the problem remains. These are the lines from the log where the cd is called and fails:

08:11:14.642 [INFO] broot::app::app: key combination: Enter

broot is not to blame, sorry. I had defined the alias in nushell config like this:

def a [] { br -gis }

This launched broot with the given flags but not the shell function somehow. If i do this instead:

alias a = br -gis 

everything works fine.

@FrancescElies @LudoPinelli @texastoland Is this behaviour to be expected from nushell or should it work in both instances?

[Francesc Elies]

@Schweber I think this is spected because of nushell scoping rules, the environment changes inside your def function stay there and do not have side effects outside the funciton, try with def --env a [] { br -gis }.

def --env is also what we used to define the br wrapper for nushell, see here

Try this two functions, cd-tmp will change directory of your current shell but cd-root won't.

def --env cd-tmp [] { cd /tmp; ls }
def cd-root [] { cd /; ls }

Does this help?

[Schweber]

Yes, thank you for the explaination. I'll close this issue and make a PR to amend the documentation.
