lua and RPM

lua

Lua support has been added to rpm for both scriptlets and macros. Some reasons for adding lua support include:

Many scripts execute simple operations which an internal interpreter requires no forking at all
Internal scripts reduce or eliminate external dependancies related to script slots
Internal scripts operate even under very minimal environments, e.g.stripped chroot, LFS, installer
Syntax errors in internal scripts are detected at build not run time

How it works:

Just use -p <lua> in any script slot.

%pre -p lua
print("Hello, Lua RPM World!")

Inline macros are done using %{lua: print ("Requirs: foo > 1.1") }. Lua provides better support for multiline macros than the standard RPM macro parser.
