[Buildroot] [PATCH 0/7 v2] [RFC] graph-depends improvements (branch yem/graphs)

[Yann E. MORIN]

From: "Yann E. MORIN" <yann.morin.1998 at free.fr>

Hello All!

This series brings a few improvements to the graph-depends utility:

  - add option to remove transitive dependencies
  - add option to pas arbitrary args to the dot utility
  - cleanup and re-arrange the code

This series is open for discusion, especially on how we pass options to
the graph generators:

  - support/scripts/graph-depends: needs to know whether to generate
    transitive dependencies or not, and how deep to limit the dependencies

  - the 'dot' utility: needs to know whether to graph top-down or
    left-right (or whatever), the type of graph (tree, circle...) and
    so on...

Currently, environment variables are used, but that is not in the tastes
of some (me including), but I can't see a better way.

Peter suggested using kconfig knobs, but it does not scale when you want
different settings for different graphs (e.g, different depth level for
different packages).

Samuel suggested using a config file, but it has the same issues as the
kconfig options. He also suggested pasing a single environment variable,
but that does not work since some options are for graph-depends shile
others are for dot.

Any other suggestion? ;-)

Regards,
Yann E. MORIN.
