Currently, when a custom path is set for any of the XDG base
directories (i.e XDG_DATA_HOME, XDG_CONFIG_HOME, ...), the path will
be coerced into a string when consumed by other options such as
xdg.configFile et al. This causes the the given path to be copied to
the nix store which in the case of xdg.configFile et al, translate to
the file being written there as it is a absolute path.
Interestingly, the default base directories all work as intended as
they are encoded as a string.
This commit converts the option to a string regardless of whether it
is a primitive path or a string encoded path. This allows downstream
consumers to use the base directories in arbitrary way without
accidentally copying the content of the directory to the store. It is
implemented in a similar manner as how home.homeDirectory undergoes
string conversion.
The existing file-attr-name test was modified to test also custom xdg
base directories, and the home.file generation test was removed as
there is a dedicated test for this case in the files module. The test
case was renamed to file-gen to better reflect the new scope.
* xdg-desktop-entries: add module
rebase
* xdg-desktop-entries: adapt to changes in makeDesktopItem
This package depends on the makeDesktopItem function in nixpkgs, which recently changed its syntax:
https://github.com/NixOS/nixpkgs/pull/91790
This commit makes the module compatible with the new syntax.
It also exposes the fileValidation option in makeDesktopItem.

There is a need to manage XDG Base Directory system directory
environment variables in Home Manager modules. There is an existing
mechanism in `targets.genericLinux.extraXdgDataDirs', but this does not
apply to NixOS systems.
Furthermore, it is important that `XDG_CONFIG_DIRS' and `XDG_DATA_DIRS'
are set in both login shells (to support getty and SSH sessions) as well
as the systemd user manager (to propagate them to user services and
desktop environments).
The first need is addressed by adding the `xdg.systemDirs' module, which
configures lists of directory names for both `config' and `data'
directories. These are then set in
`$XDG_CONFIG_DIR/environment.d/10-home-manager.conf' and picked up by
the systemd user manager.
To make these, and other variables set in
`systemd.user.sessionVariables', available in login shells, an
additional step is added to `etc/profile.d/hm-session-vars.sh' which
exports the result of
`user-environment-generators/30-systemd-environment-d-generator' which
is shipped with systemd. The effect of this generator is to print
variables set on the systemd user manager such that shells can import
these into their environment.
