<para>
A type that accepts any value and recursively merges attribute sets together.
This type is recommended when the option type is unknown.
<example xml:id="ex-types-anything">
<title><literal>types.anything</literal> Example</title>
<para>
Two definitions of this type like
<programlisting>
{
str = lib.mkDefault "foo";
pkg.hello = pkgs.hello;
fun.fun = x: x + 1;
}
</programlisting>
<programlisting>
{
str = lib.mkIf true "bar";
pkg.gcc = pkgs.gcc;
fun.fun = lib.mkForce (x: x + 2);
}
</programlisting>
will get merged to
<programlisting>
{
str = "bar";
pkg.gcc = pkgs.gcc;
pkg.hello = pkgs.hello;
fun.fun = x: x + 2;
}
</programlisting>
</para>
