No entry for configuration.nix in section 5 of the manual

[Pablo1107]

When running

man 5 configuration.nix

Probably an error with my flake configuration since I also use home-manager, but I find it hard to debug how the $MANPATH is set up.

Some info, which man and which manpath points to /usr/bin which idk if that should be the case. And echo $MANPATH is missing /run/current-system/sw/share/man, should I add this to the $MANPATH by myself?

Do you have the following in your configuration?

{
  documentation.enable = true;
}

This will enable the manpages for nix-darwin and the system packages, and enable the man package.

Yes, I do have that option enabled, but I don't think the environment variables are correctly set in my shell.

What's the actual error?

What's the actual error?

No error, the message is the title of this issue. man does not seems to find any nix-darwin manpages.

nix-darwin doesn't set the MANPATH per default and you shouldn't have to do it either. The same goes for documentation.enable, because true is the default.

However, in my case I get the man bin from my nix-profile. darwin-option documentation.enable and darwin-option programs.man.enable both report true as a current val?

Can you run darwin-help? This should open the manpage in your browser.

darwin-option does not work, because I configure nix darwin via flakes. darwin-help does work, but I lack all the nix-darwin installed man pages. Also, as I pointed out in the OP, which man outputs /usr/bin/man which I supposed is the culprit. Maybe that should point to a nix man instead, but the order in the path prioritizes /usr/bin over nix binaries which idk if that should be like that or not, again, noobie question.

Are you still running into this issue? I believe man should determine the MANPATH variable from the PATH variable, so you shouldn't have MANPATH set in your terminal.

I actually don't have a MacBook anymore so I cannot test. If nobody can reproduce, we can close this.

I'll close this for now, if anyone else can reproduce this, feel free to leave a comment :+1:
