(Purity means + that building and using the standard environment has no dependencies + outside of the Nix store. For instance, it doesn’t require an + external C compiler such as <filename>/usr/bin/gcc</filename>.) + Also, the statically linked binaries used in the bootstrap process + are now automatically reproducible, making it easy to update the + bootstrap tools and to add support for other Linux platforms.

This + has a major advantage: you can write hooks directly in Nix + expressions. For instance, rather than write a builder like this: + +<programlisting> +source $stdenv/setup + +postInstall=postInstall +postInstall() { + ln -sf gzip $out/bin/gunzip + ln -sf gzip $out/bin/zcat +} + +genericBuild</programlisting> + + (the <literal>gzip</literal> builder), you can just add this + attribute to the derivation: + +<programlisting> +postInstall = "ln -sf gzip $out/bin/gunzip; ln -sf gzip $out/bin/zcat";</programlisting> + + and so a separate build script becomes unnecessary. This should + allow us to get rid of most builders in Nixpkgs.</para></listitem> + + + <listitem><para>It is now possible to have the generic builder pass + arguments to <command>configure</command> and + <command>make</command> that contain whitespace. Previously, for + example, you could say in a builder, + +<programlisting> +configureFlags="CFLAGS=-O0"</programlisting> + + but not + +<programlisting> +configureFlags="CFLAGS=-O0 -g"</programlisting> + + since the <literal>-g</literal> would be interpreted as a separate + argument to <command>configure</command>.
