Vladimír Čunát ef21e5ee60 nixpkgs manual: split languages into separate files
There's no change in content except for amending the title of the
section to mention "frameworks", as e.g. I don't consider Qt a language,
and it's likely there will be more of similar cases in future.

To be certain, I checked diff of the generated HTMLs.

<title>Lua</title>
<para>
Lua packages are built by the <varname>buildLuaPackage</varname> function. This function is
implemented
in <link xlink:href="https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/lua-modules/generic/default.nix">
<filename>pkgs/development/lua-modules/generic/default.nix</filename></link>
and works similarly to <varname>buildPerlPackage</varname>. (See
<xref linkend="sec-language-perl"/> for details.)
</para>
<para>
Lua packages are defined
in <link xlink:href="https://github.com/NixOS/nixpkgs/blob/master/pkgs/top-level/lua-packages.nix"><filename>pkgs/top-level/lua-packages.nix</filename></link>.
Most of them are simple. For example:
<programlisting>
fileSystem = buildLuaPackage {
name = "filesystem-1.6.2";
src = fetchurl {
url = "https://github.com/keplerproject/luafilesystem/archive/v1_6_2.tar.gz";
sha256 = "1n8qdwa20ypbrny99vhkmx8q04zd2jjycdb5196xdhgvqzk10abz";
};
meta = {
homepage = "https://github.com/keplerproject/luafilesystem";
hydraPlatforms = stdenv.lib.platforms.linux;
maintainers = with maintainers; [ flosse ];
};
};
</programlisting>
</para>
<para>
Though, more complicated package should be placed in a seperate file in
<link
xlink:href="https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/lua-modules"><filename>pkgs/development/lua-modules</filename></link>.
</para>
<para>
Lua packages accept additional parameter <varname>disabled</varname>, which defines
the condition of disabling package from luaPackages. For example, if package has
<varname>disabled</varname> assigned to <literal>lua.luaversion != "5.1"</literal>,
it will not be included in any luaPackages except lua51Packages, making it
only be built for lua 5.1.
