Adds support for
section = [
"abc"
{ a = 123; }
];
Which gets generated to
section=abc
section {
a=123
}
This is very useful with the new windowrule syntax, where you can
create anonymous window rules as strings and named rules as attribute
sets. See <https://wiki.hypr.land/Configuring/Window-Rules/>.
Instead of having to manually stub packages that should not be
downloaded we instead automatically stub all packages (except a small
list of whitelisted ones). Tests can re-introduce the real package by
using the `realPkgs` module argument.
The systemd user service depends on
config.xdg.configFile."hypr/hyprpaper.conf".source
for `X-Restart-Triggers`. When `cfg.settings` is the default `{}`,
this causes failure since
config.xdg.configFile."hypr/hyprpaper.conf".source
will not exist.
Making the addition conditional on `cfg.settings` actually having
content, which would mean `xdg.configFile."hypr/hyprpaper.conf"` does
exist, avoids the error.
