Hi,
I am playing with it right now, but I had to patch it this way to make
it work with my /etc/portage/package.* directories:
--- empi.old 2008-05-14 19:35:00.000000000 +0200
+++ empi.new 2008-05-14 19:39:30.000000000 +0200
@@ -106,7 +106,7 @@
fi
if ! grep "[>=<]*${imp}/${atom[1]}" ${gfiles} &>/dev/null; then
- grep "[>=<]*${atom[0]}/${atom[1]}" ${gfiles} 2>/dev/null \
+ grep -h "[>=<]*${atom[0]}/${atom[1]}" ${gfiles} 2>/dev/null \
| sed "s,${atom[0]},${imp}," \
| while read line; do
echo "${line}" >> ${f}
otherwise grep will produce a wrong output because it will prefix the
file name before the found expression and something like this is put
inside the keyword file:
/etc/portage/package.keywords/base:mpi-test/openmpi ~x86
Thanks,
David.
