<para>The ‘<literal>with</literal>’ language construct is now more
|
||||
lazy. It only evaluates its argument if a variable might actually
|
||||
refer to an attribute in the argument. For instance, this now
|
||||
works:
|
||||
|
||||
<programlisting>
|
||||
let
|
||||
pkgs = with pkgs; { foo = "old"; bar = foo; } // overrides;
|
||||
overrides = { foo = "new"; };
|
||||
in pkgs.bar
|
||||
</programlisting>
|
||||
|
||||
This evaluates to <literal>"new"</literal>, while previously it
|
||||
gave an “infinite recursion” error.</para>

|
||||
<para>Nix now has proper integer arithmetic operators. For
|
||||
instance, you can write <literal>x + y</literal> instead of
|
||||
<literal>builtins.add x y</literal>, or <literal>x <
|
||||
y</literal> instead of <literal>builtins.lessThan x y</literal>.
|
||||
The comparison operators also work on strings.</para>

<para>On 64-bit systems, Nix integers are now 64 bits rather than

32 bits.</para>

<para>When using the Nix daemon, the <command>nix-daemon</command>
|
||||
worker process now runs on the same CPU as the client, on systems
|
||||
that support setting CPU affinity. This gives a significant speedup
|

on some systems.</para>

<para>If a stack overflow occurs in the Nix evaluator, you now get

a proper error message (rather than “Segmentation fault”) on some

systems.</para>

<para>In addition to directories, you can now bind-mount regular

files in chroots through the (now misnamed) option

<option>build-chroot-dirs</option>.</para>
