Ah the macro expansion limit. The limit is currently at 110K iirc. The buffer size is tunable in rpmio/macros.c, the 110Kb is known to work for OpenPKG (which is using embedded lua extensively). lua _IS_ a programming language, you should not be limited by whatever size a macro expansion buffer is. If you do hit the limit, you should likely change your approach to use, say, /tmp files! wotta concept! 73 de Jeff ______________________________________________________________________ RPM Package Manager http://rpm5.org User Communication List rpm-users@rpm5.org
