||||
obtain derivations. The `--file` option may be used to override
|
||||
this default.
|
||||
|
||||
If `~/.nix-defexpr` is a file, it is loaded as a Nix expression. If
|
||||
the expression is a set, it is used as the default Nix expression.
|
||||
If the expression is a function, an empty set is passed as argument
|
||||
and the return value is used as the default Nix expression.
|
||||
|
||||
|
||||
If `~/.nix-defexpr` is a directory containing a `default.nix` file,
|
||||
that file is loaded as in the above paragraph.
|
||||
|
||||
|
||||
If `~/.nix-defexpr` is a directory without a `default.nix` file,
|
||||
then its contents (both files and subdirectories) are loaded as Nix
|
||||
expressions. The expressions are combined into a single set, each
|
||||
expression under an attribute with the same name as the original
|
||||
file or subdirectory.
|
||||
|
||||
|
||||
For example, if `~/.nix-defexpr` contains two files, `foo.nix` and
|
||||
`bar.nix`, then the default Nix expression will essentially be
|
||||
|
||||
|
||||
{
|
||||
foo = import ~/.nix-defexpr/foo.nix;
|
||||
bar = import ~/.nix-defexpr/bar.nix;
|
||||
}
|
||||
|
||||
|
||||
The file `manifest.nix` is always ignored. Subdirectories without a
|
||||
`default.nix` file are traversed recursively in search of more Nix
|
||||
expressions, but the names of these intermediate directories are not
|
||||
added to the attribute paths of the default Nix expression.
|
||||
|
||||
|
||||
The command `nix-channel` places symlinks to the downloaded Nix
|
||||
expressions from each subscribed channel in this directory.

commands such as `nix-build` that place a symlink to the build

result in the current directory; such a build result should not be

garbage-collected unless the symlink is removed.
|
||||
|

|

The `--indirect` flag causes a uniquely named symlink to *path* to
|
||||
be stored in `/nix/var/nix/gcroots/auto/`. For instance,
|
||||
|
||||
|

$ nix-store --add-root /home/eelco/bla/result --indirect -r ...

|

Thus, when `/home/eelco/bla/result` is removed, the GC root in the

`auto` directory becomes a dangling symlink and will be ignored by

the collector.
