Great!
This make me remember that I used dpkg-parsechangelog in man-db's configure.in
to get both the version and the maintainer's entry.
Although very slow (on my 486) I think I'll use these for my "all numeric"
library packages:
===================================================================
ver_info = ${shell LC_ALL=C \
dpkg-parsechangelog 2>/dev/null \
| awk '/^Version:/{ print $$2 }' }
full_ver = ${shell expr "${ver_info}" : '\([0-9.]*\)'}
major_ver = ${shell expr "${ver_info}" : '\([0-9]*\).[0-9]*'}
debian_ver = ${shell expr "${ver_info}" : '[0-9.]*-\([0-9.]*\)'}
===================================================================
A perl addict would prefere to use this line to extract the three
informations, although I dubt its speed:
LC_ALL=C dpkg-parsechangelog 2>/dev/null \
| perl -ne 'print $1,"\n",$2,"\n",$3,"\n" \
if /^Version:.*\s(([0-9]*).[0-9.]*)-([0-9.]*)/;'
fab - who loves this thread :-)
