Sure, people love and use it (for example the Lua-interface is a killer feature which yum currently lacks) but it's starting to seem like a dead end to me.
So how should lua be made available to yum?
Current implementation of lua in rpm is through %{lua: ...} macro constructs,
grotesque mainly because of the necessity to preserver a "stable" and constant
rpm-python interface. E.g. there is no way to simply expand a macro, one has to
go through the baggage of hdr.sprintf() where rpmExpand() to invoke lua happens
as side effect. That's obscure enough to pass for "stable", sigh.
Easy enough to rip several layers off the above, what stops is no need to do so yet.
Hum a few notes about what you'ld like to see lua used for in yum, please. I think
lua has definite and positive benefits for rpm packaging, becuase for the first time
rpmlib can run scripts without the baggage of scriptlet dependencies. Lots of dependencies
would (will imho) simply melt away if lua rather than shell were used for the 20 or so
common operations performed by package scriptlets.
