This commit introduces the `nixpkgs-disabled` module, that is
basically a mock of `nixpkgs` module where any value different from
`null` will cause an assertion error.
This is to help debugging cases where `home-manager.useGlobalPkgs` is
set to `true` and `nixpkgs.*` options are being used.
Nowadays this returns the following error:
```
error: The option `home-manager.users.<user>.nixpkgs` does not exist.
```
This will change too:
```
error: `nixpkgs` options are disabled when `home-manager.useGlobalPkgs` is enabled.
```
That will direct the user to the correct solution (either removing
`nixpkgs` or disable `home-manager.useGlobalPkgs`).
Having either argument defined based on the OS is a problem when
trying to write generic Nix code.
The current workaround is to use accept both and specify a default
value for each argument:
```
{ config, lib, nixosConfig ? {}, darwinConfig ? {}, ... }:
let
osConfig = nixosConfig // darwinConfig;
in
{
# Do something with `osConfig`
}
```
With this commit, it becomes possible to do the following:
```
{ config, lib, osConfig, ... }:
{
# Do something with `osConfig`
}
```
- Add NIXPKGS_REV, so we can pass arbitrary revisions for testing (for
example, `release-21.05` so we can test backports).
- Add format target, that calls the format script.
nnn is a terminal file manager.
It is configured mostly using environment variables, so the way I
found it to avoid needing to write either shell specific code or
using `home.sessionVariables` (that would need to make the user
relogin at every configuration change) is to wrap the program using
`wrapProgram`.
This is to better integrate with more advanced shell history managers
like McFly and Atuin. By initializing fzf first, we allow the history
managers to steal the C-r key binding from fzf.
This commit adds a module for configuring atuin, a replacement shell
history program.
The module adds options for generating atuin's `config.toml` from Nix,
and options to enable atuin's integration for bash and zsh
(which will rebind history keys to open the atuin history).
* screen-locker: Make xautolock optional, reorganize options
xautolock isn't really needed to trigger xss-lock on the basis of time
since the built-in screensaver functionality of X serves as one of the
event sources for xss-lock. Keeping it around and defaulting to
"enabled" to avoid unexpected breakage.
Also shuffled around the options to submodules for xss-lock and
xautolock to get rid of prefixes in option names and to make
enableDetectSleep a bit clearer.
* screen-locker: update maintainership
* tests/screen-locker: Stub i3lock and xss-lock
* screen-locker: add package options for xss-lock and xautolock
kanshi configurations can have more than one exec statement in a
profile. This change allows services.kanshi.profiles.<name>.exec to be
a list of strings rather than a single string.
The idea of this file is to make it easier to run tests. It will ensure
that the tests are running with the correct NIX_PATH (pointing it to
e.g.: unstable), and also allowing it to run either one or all tests.
This option provides a more convenient way to overlay dummy packages.
It also adds a function `config.lib.test.mkStubPackage` that can,
e.g., be used for `package` options.
If the user has a running systemd session, source their environment
from the systemd manager and export a few variables in order to allow
activation scripts to reload applications on the fly.
The list of variables to export is arbitrary and could be extended in
the future.
Fixes#1399, fixes#2112.
Specifically, instead of
services.dbus.packages = with pkgs; [ gnome.dconf ];
we now recommend
programs.dconf.enable = true;
which does the same and more.
