Determines whether to check for release version mismatch between Home Manager and Nixpkgs. Using mismatched versions is likely to cause errors and unexpected behavior. It is therefore highly recommended to use a release of Home Manager than corresponds with your chosen release of Nixpkgs.

Type: boolean

Default: false

Declared by:

The set of packages to appear in the user environment.

Type: list of packages

Default: [ ]

Declared by:

The activation scripts blocks to run when activating a Home Manager generation. Any entry here should be idempotent, meaning running twice or more times produces the same result as running it once.

If the script block produces any observable side effect, such as writing or deleting files, then it must be placed after the special writeBoundary script block. Prior to the write boundary one can place script blocks that verifies, but does not modify, the state of the system and exits if an unexpected state is found. For example, the checkLinkTargets script block checks for collisions between non-managed files and files defined in home.file.

A script block should respect the DRY_RUN variable, if it is set then the actions taken by the script should be logged to standard out and not actually performed. The variable DRY_RUN_CMD is set to echo if dry run is enabled.

A script block should also respect the VERBOSE variable, and if set print information on standard out that may be useful for debugging any issue that may arise. The variable VERBOSE_ARG is set to --verbose if verbose output is enabled.

Default: { }

Example:

{
  myActivationAction = lib.hm.dag.entryAfter ["writeBoundary"] ''

Note, this code is always run when recursive is enabled.

Type: strings concatenated with "\n"

Default: ""

Declared by:

If the file source is a directory, then this option determines whether the directory should be recursively linked to the target location. This option has no effect if the source is a file.

"${home.homeDirectory}/.nix-profile"  or
"/etc/profiles/per-user/${home.username}"

Declared by:

Extra directories to add to PATH.

These directories are added to the PATH variable in a double-quoted context, so expressions like $HOME are expanded by the shell. However, since expressions like ~ or * are escaped, they will end up in the PATH verbatim.

Type: list of strings

Default: [ ]

Example: [ "$HOME/.local/bin" "\${xdg.configHome}/emacs/bin" ".git/safe/../../bin" ]

Declared by:

Environment variables to always set at login.

The values may refer to other environment variables using POSIX.2 style variable references. For example, a variable parameter may be referenced as $parameter or ${parameter}. A default value foo may be given as per ${parameter:-foo} and, similarly, an alternate value bar can be given as per ${parameter:+bar}.

Note, these variables may be set in any order so no session variable may have a runtime dependency on another session variable. In particular code like

home.sessionVariables = {
  FOO = "Hello";
  BAR = "$FOO World!";
};

may not work as expected. If you need to reference another session variable, then do so inside Nix instead. The above example then becomes

home.sessionVariables = {
  FOO = "Hello";
  BAR = "${config.home.sessionVariables.FOO} World!";
};

Type: attribute set

Default: { }

Example: { EDITOR = "emacs"; GS_OPTIONS = "-sPAPERSIZE=a4"; }

Declared by:

An attribute set that maps aliases (the top level attribute names in this option) to command strings or directly to build outputs.

This option should only be used to manage simple aliases that are compatible across all shells. If you need to use a shell specific feature then make sure to use a shell specific option, for example programs.bash.shellAliases for Bash.

Type: attribute set of strings

Default: { }

Example:

{
  g = "git";
  "..." = "cd ../..";
}

Declared by:

It is occasionally necessary for Home Manager to change configuration defaults in a way that is incompatible with stateful data. This could, for example, include switching the default data format or location of a file.

The state version indicates which default settings are in effect and will therefore help avoid breaking program configurations. Switching to a higher state version typically requires performing some manual steps, such as data conversion or moving files.

Type: one of "18.09", "19.03", "19.09", "20.03", "20.09", "21.03", "21.05", "21.11", "22.05"

Default: "18.09"

Declared by:

The user's username.

Type: string

Default:

"$USER"   for state version < 20.09,
undefined for state version ≥ 20.09

Example: "jane.doe"

The configuration of the Nix Packages collection. (For details, see the Nixpkgs documentation.) It allows you to set package configuration options.

If null, then configuration is taken from the fallback location, for example, ~/.config/nixpkgs/config.nix.

Note, this option will not apply outside your Home Manager configuration like when installing manually through nix-env. If you want to apply it both inside and outside Home Manager you can put it in a separate file and include something like

  nixpkgs.config = import ./nixpkgs-config.nix;
  xdg.configFile."nixpkgs/config.nix".source = ./nixpkgs-config.nix;

in your Home Manager configuration.

List of overlays to use with the Nix Packages collection. (For details, see the Nixpkgs documentation.) It allows you to override packages globally.

If null, then the overlays are taken from the fallback location, for example, ~/.config/nixpkgs/overlays.

Like nixpkgs.config this option only applies within the Home Manager configuration. See nixpkgs.config for a suggested setup that works both internally and externally.

Type: null or list of nixpkgs overlays
