Directrices de Empaquetamiento Lua
¿Qué es Lua?
Como se describe en el sitio web Lua, Lua es
"Lua es un lenguaje de script poderoso, eficiente, de poco peso e integrable. Soporta programación procesal, programación orientada a objetos, programación funcional, programación basada en datos y descripción de datos."
Para aprender Lua, lea Programando en Lua.
Plantilla de Especificaciones para un Paquete Lua
Muchos paquetes Lua usan Lua-rocks para el empaquetamiento. Es útil examinar la especificación .rockspec como guía para escribir su archivo de especificaciones. Algunos paquetes requieren la compilación de programas en C, pero otro pueden ser Lua puros. Ambos tendrán unas ubicaciones de instalación muy similares.

Naming
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
The following macros for packaging lua extensions are provided by the lua-devel package:
| Macro | Description |
|---|---|
|
version of system installed lua |
|
installation directory for compiled modules |
|
installation directory for arch-independent modules |
|
declares the needed runtime dependencies for the binary package |
For EPEL, define the following macros at the 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 them like this:
Requires: lua >= %{lua_version}
Requires: lua < %{lua: os.setlocale('C'); print(string.sub(_VERSION, 5) + 0.1)}
