See mk/ and mk/scripts/depends-depth-first.awk

I would like to see indentation, perhaps optional, basically 2 spaces
before each package that is a dependency of dependency, and so on, but
given that it's not a tree, that's harder.

Note that show-depends does not recurse.  I've wondered if there's a
canonical way to get the full recursive list.  In the past I've used the
hack of just running make clean-depends.

Yes, but I think show-depends-pkgpaths does

NetBSD netbsd9.acadix  bacon ~/Pkgsrc/pkgsrc/biology/canu 1002:
(pkgsrc): bmake show-depends
[very few dependencies]

NetBSD netbsd9.acadix  bacon ~/Pkgsrc/pkgsrc/biology/canu 1003:
(pkgsrc): bmake show-depends-pkgpaths
[some more dependencies]

NetBSD netbsd9.acadix  bacon ~/Pkgsrc/pkgsrc/biology/canu 1004:
(pkgsrc): bmake clean-depends
===> Cleaning for [really each dependency]
Thank you for the impressive example, showing the surprising differences.

The target clean-depends is a good hint.  I had a look at all
occurrences of _DEPENDS_WALK_CMD, and none of them is intended to use as
a query of its own.  There is indeed a hacky, ugly way of listing all
dependencies, without touching anything in mk/:

$ bmake clean-depends RECURSIVE_MAKE='echo $$dir; :'

(If you want to see how and why it works, have a look at

There should be a cleaner way of listing all of a package's
dependencies.  My first idea was to define a target named
'show-all-depends', but that name is already used as part of 'show-all'.
 Therefore I suggest 'show-depends-all'.  The implementation is
trivial, to be added to mk/

show-depends-all: .PHONY

# Support for an indented dependency tree would require additional
# work in mk/scripts/
$ bmake show-depends-all INDENT='  '
