The created command shows, recursively, the reverse depends of a
package,
it means that the command shows not only the direct dependants (which is
done by 'show-rdepends'), but also all indirect dependents.
To do this it was necessary to create a new parameter '--flat-list', or
'-f', to graph-depends.
This parameter instructs the script to just print the name of package
instead of the .dot syntax.

It is better to use the approach like for show-build-order, i.e.:
$(1)-show-rrdepends: $$(patsubst %,%-rrdepends,$$($(2)_FINAL_ALL_DEPENDENCIES))
@printf '%s' $$($(2)_RDEPENDENCIES)
However, I would much prefer to rewrite graph-depends completely so it works in
a single pass, and have just pkg-show-depends that works recursively like above.
Then any filterling like depth or just a single package or reverting the arrows
can be done by the graph-depends script itself. That would work a whole lot
faster, and in addition would allow us to remove a lot of those annoying extra
rules inside inner-generic-package (cfr. my rant recently).
But that is of course a much bigger change, so for the time being I'm OK with
adding this rrdepends.

Arnout

Hi Arnout,
Sometimes I want to recompile all reverse-dependant packages, including indirect dependents.
So if I have the list of these packages, it's pretty easy to recompile them.
Using the approach you suggested some packages are repeatedly printed.
Suppose the package A depends on packages B and C, and both B and C depends on package D.
When I run show-rrdepends over D, I want to see "B C A", but with your proposed approach the output will be "B A C A" because It does not handle the already printed packages.
However the graph-depends script handle this case and that's one of the reasons I implemented it in this script.

I didn't exactly "accept" this patch. I thought the implementation was
acceptable, but I wasn't entirely sure the use case was important enough to
warrant the additional complexity.
If I understand the use case correctly, what you want is that you have changed
something in package A, so you want to rebuild package A and all its recursive
dependencies. For that, a recursive dirclean is probably more appropriate:
$(1)-dirclean-recursive: $(1)-dirclean $$(patsubst
%,%-dirclean-recursive,$$($(2)_FINAL_ALL_DEPENDENCIES))
Regards,
Arnout

Not exactly the same i guess, i think this will rebuild package A and all its dependencies (we are going "down" on dependencies).
The point of this script is to rebuild package A and all those who depends on it (we are going "up" on dependencies).
Based on previous work done on the reverse-dependencies (make <pkg>-show-rdepends), this has been turned in recursive-reverse-dependencies.
