NixOS colorful man pages, and support home-manager packages

NixOS-colorful-man-pages.md

1. Get colorful man pages

• replace man-db with mandoc, see NixOS wiki, and install most

in configuration.nix

documentation.man = {
# In order to enable to mandoc man-db has to be disabled.
man-db.enable = false;
mandoc.enable = true;
};
environment.sysemPackages = [
pkgs.most
];

you may want to install extra man pages, see above wiki

• use most as MANPAGER, try it at terminal

MANPAGER=most man nix

now we have colorful man pages.

2. home-manager configuration

• home-manager default to enable man-db and not supporting mandoc at the moment (2024-04), so we need to disable it and use our man command from mandoc.

  program.man.enable = false;

• configura MANPAGER to most, need to re-login to take effect:

home.sessionVariable = {
  MANPAGER = "most";
};

• tell mandoc to find our man pages installed via home-manager

shellAlias = {
  man = "man -m ~/.nix-profile/share/man";
};
