Man pages are a form of documentation available on Unix-like systems.
See the Archwiki and Wikipedia entries for more information.
NixOS: Display configuration options
The NixOS option system creates a manpage with all options and their documentation.
$ man 5 configuration.nix
This is a lightweight alternative to the “Configuration Options” page in nixos-help.
There is also NixOS options website
NixOS: Some man pages are missing
Development man pages
The “Linux man-pages project” provides a set of documentation of the Linux programming API, mostly section `3`. You can access them by adding them to your system packages:
environment.systemPackages = [ pkgs.man-pages pkgs.man-pages-posix ];
To try it out: man 3 scanf.
Libraries and development utilities might provide additional documentation and manpages. You can add those to your system like this:
documentation.dev.enable = true;
See also: the other options in the `documentation` namespace.
Mandoc as the default man page viewer
Mandoc is a set of tools designed for working with mdoc(7), the preferred roff macro language for BSD manual pages, as well as man(7), the historical roff macro language used in UNIX manuals. It can be used as an alternative to man-db.
To use mandoc as the default man page viewer add following code to your config:
documentation.man = {
# In order to enable to mandoc man-db has to be disabled.
man-db.enable = false;
mandoc.enable = true;
};
See also: the Mandoc website.
