So,
if $(has_version "<sys-fs/udev-046"); then
ewarn
fi
...
if $(has_version "<sys-fs/udev-059"); then
ewarn
fi
For gaim maybe something like this:
+if ! $(has_version "~${PV}" ); then
ewarn
- ewarn "If you are merging ${P} from an earlier version, you may need"
- ewarn "to re-merge any plugins like gaim-encryption or gaim-snpp."
+ ewarn "You may need to re-merge any plugins like gaim-encryption or
gaim-snpp."
Maybe a function in an eclass can make this easier on people?
if $(package_is "<" 046); then
...
and package_is (name derived from kernel_is, don't flame the name, it is
for illustration only) could be something like this:
package_is() {
return $(has_version "${1}${CATEGORY}/${PN}-${2}")
}
That should be good enough for all packages, right?
One more thing. has_version would not necessarily detect the version we
are upgrading from (i.e., the version that will be removed after
installation) if there is a slotted package. Could that become a
problem?
