By not using the home file name in a derivation name, the home file name
is no longer exposed to the naming restrictions for nix store paths.
For example, it's now possible to define home files with spaces in their
names without providing a target or source attribute.
This command allows the user to examine the news items generated by
the news module. See #52.
Many thanks to @nonsequitur and @uvNikita for suggestions and
improvements.
1. It slows down the initial start: it takes around 2s at first launch,
and around 0.25s for the following launches;
2. It seems to be redundant since just installing zsh package gives
working completions with correct $fpath set.
Technically not necessary but it was a bit silly to leave out this
important directory from the generation directory. This also makes it
more convenient to browse the installed packages after a
`home-manager build`.
With --ignore-fail-on-non-empty, non-emptiness is the only failure
that gets ignored by rmdir. In the case that rmdir reaches $HOME and
considers deleting it, it will detect insufficient permissions and
subsequently exit with an error, even if $HOME is not empty.
Prevent this by calling rmdir with a relative path that excludes
$HOME.
We must only follow the symbolic link once (i.e., not use the `-e`
option) since otherwise the pattern will not match when
`home.file.xyz.source` is a directory.
If the `home-manager` module is enabled then check if the
`home-manager` package is installed using `nix-env -i` and if so then
it is automatically uninstalled before the new package environment,
which includes home-manager, is installed.
This module is a module to install and configure the home-manager
tool. By managing the home-manager tool through the Home Manager
module system it will be installed/updated on configuration
activation.
Problem
-------
We resolve symlinks from inside `/nix/store/HASH-home-manager-files`
into the nix store as `/nix/store/HASH-DRVNAME` which does not match
the pattern.
This happened to me because I pull in some repos in via `home.file`.
The `home-manager-files` derivation links to the repo's derivation in
the nix store. For example:
let nanorcs = fetchFromGitHub {
owner = "scopatz";
repo = "nanorc";
…
}; in [
{
target = ".nano";
source = nanorcs;
}
{
target = ".nanorc";
source = "${nanorcs}/nanorc";
}
]
Solution
--------
Call `readlink` without `-e` to obtain only the first redirection from
`~` to `/nix/store/HASH-home-manager-files`.
When a file has disappeared between the previous and the next
generations then its symlink in `$HOME` is typically deleted. With
this commit we refuse to delete the path unless we are reasonably
certain it is a symlink into a Home Manager generation.
