IMO this is much more readable than an endless line and it eases to track changes in cvs considerably. You see immediately which dependencies have changed.
How about recommending the use of here-doc structures for Depends and BuildDepends in the packaging manual?
This seems more about esthetics; on the other hand, as to the users'
ease of use, the one line format allows to immediately get the dependencies
of a set of packages by a command like " f_whch <pkgs>|xargs grep 'Depends:' "
(where f_whch _ 'fink which' _ outputs, for each listed pkg succesively, a line
with the full path to the exact info file fink would use for that pkg _ cf eg
http://article.gmane.org/gmane.os.apple.fink.devel/7304/match=
for such a script).
Similarly, to get the set of pkgs that eg still depend on gd a simple
egrep -rI '[, ]gd([, ]|$)' /sw/fink/dists/unstable|grep 'Depends:'
suffices with the 1 line convention.
(And as long as only a dozen pkgs don't follow that convention, it is still tolerable)
I guess you mention that dozen pkgs maintained by me (-; Following your line of thought you will have to forbid the use of the here-doc structure for dependencies. Otherwise your simple grep reports an incomplete set of packages which is bad IMHO.
Is it really worthwhile to complicate so much such simple uses ???
Well I guess that's a question of preferences. I prefer the readability of the Depends/BuildDepends line in the info file. I think it is less error prone and makes the comparison between Depends and BuildDepends easier. I guess a functionality for printing all packages depending on a given package could be quite easily implemented in fink itself.
Cheers,
Remi
