Question: Is the `9p` executable required for navigating the tour?

[legendre6891]

Hi - this is an interesting project and after watching the video in your blog, I'm curious to learn more.

When I'm navigating the tour, I see this error message

.../lib/ad.sh: line[xx] 9p command not found

Evidently, this means that I should have a binary 9p in my shell's PATH. Is this binary supplied with the repo, or is this meant as a 3rd party runtime dependency that the user should install themselves? Thanks.

I'm not the owner, but I think I know the answer: Yes it is required. I got mine from plan9port.

ah sorry @legendre6891, I really should call that out on the first slide of the tour. The fsys slide mentions it but nothing talks about how to install it I don't think. I've been wondering about allowing ad itself to be used as a 9p client via a flag so you don't need to have 9p as a separate binary.

@sminez 👋 Is there anything else required other than installing the 9p tools?

I installed https://github.com/9fans/plan9port, and the 9p tool is available and in PATH, and when I try to use "@" on "Slide" -- I get this error:

@izuzak ah, can you try exporting NAMESPACE="/tmp/ns.$USER.$DISPLAY" and trying again? I thought that was used by default by the 9p tool but maybe not

@sminez Sure sure! I now get something else:

I'm on MacOS Sequoia 15.2, in case that's relevant. Apologies if I'm missing something obvious, and totally feel free to just tell me it's all in the docs for https://github.com/9fans/plan9port and I'll go read that 😸

No, it's me making assumptions about running under X11 I'm afraid. I've just double checked the ninep crate and there I'm not using $DISPLAY, I'm just hard coding :0 it seems. So for now you'll need to export NAMESPACE=/tmp/ns.$USER.:0 and that should do it 🤞

Yay, that fixes things indeed. 👍 Many thanks!
