From Fedora 16 and onwards ('''not''' RHEL 6!), the main <code>lua</code> package virtually provides <code>lua(abi) = %{luaver}</code>, so packages targeting this release and above should declare this runtime dependency:
 
 
 
<pre>
 
Requires: lua(abi) = %{luaver}
 
 
</pre>
 
</pre>
  
to target older releases (or RHEL 6), you must use the following instead.
 
 
<pre>
 
%global luanext 5.2
 
Requires: lua >= %{luaver}
 
Requires: lua <  %{luanext}
 
</pre>
 
  
To target both releases, use %if guards as follows:
+
To make the package pull the correct runtime dependencies, declare it like this:
  
 
<pre>
 
<pre>
%if 0%{?fedora} || 0%{?rhel} >= 7
+
%if 0%{?fedora} >= 16 || 0%{?rhel} >= 7
...
+
Requires: lua(abi) = %{lua_version}
 
%else
 
%else
...
+
Requires: lua >= %{lua_version}
 +
Requires: lua <  %{lua: os.setlocale('C'); print(string.sub(_VERSION, 5) + 0.1)}
 
%endif
 
%endif
 
</pre>

Naming

(This section should eventually be linked from Packaging:NamingGuidelines)

Lua add-on packages generally follow the naming scheme of lua-modulename -- e.g. lua-filesystem, lua-lpeg, lua-moonscript. If the module name makes it clear that it is an add-on for Lua, though, the module name itself is sufficient. e.g. lutok.

Use your judgement -- e.g. the second l in lua-lpeg already stands for Lua, but it might not be seen as unambiguous enough.


Macros

Starting with Fedora 24, the following macros for packaging lua extensions are provided by the lua-devel package:

Macro Contents
%lua_version version of system installed lua
%lua_libdir installation directory for compiled modules
%lua_pkgdir installation directory for arch-independent modules
%lua_requires declares the needed runtime dependencies for the binary package

EPEL ONLY
This is for EPEL only. Fedora provides the packaging macros above.


Define the following on top of your spec file:

%{!?lua_version: %global lua_version %{lua: print(string.sub(_VERSION, 5))}}
# for compiled modules
%{!?lua_libdir: %global lua_libdir %{_libdir}/lua/%{lua_version}}
# for arch-independent modules
%{!?lua_pkgdir: %global lua_pkgdir %{_datadir}/lua/%{lua_version}}


To make the package pull the correct runtime dependencies, declare it like this:

%if 0%{?fedora} >= 16 || 0%{?rhel} >= 7
Requires: lua(abi) = %{lua_version}
%else
Requires: lua >= %{lua_version}
Requires: lua <  %{lua: os.setlocale('C'); print(string.sub(_VERSION, 5) + 0.1)}
%endif

Rocks

Upstream Lua developers increasingly use LuaRocks to distribute their modules. We are exploring providing better integration with LuaRocks in the future -- both in generating spec files from .rockspec specifications, and in shipping a luarocks package that can pick up existing RPM-installed Lua packages, but for the time being, you can use upstream rockspec specifications to guide your packaging work.
