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.
So I went for:
- renaming the existing DEPTH variable: we can do that since it's
been in no release for now (quick! let's apply at least the first
patch for this cycle! ;-) )
- add a new variable to pass options to dot
Changes v2 -> v3:
- pythonise even further the handling of --depth (Samuel)
- rename BR2_GRAPH_DEPTH to BR2_GRAPH_DEPS_OPTS
- introduce BR2_GRAPH_DOT_OPTS
- update manual accordingly
Changes v1 -> v2:
- complete rewrite, split into a series
Regards,
Yann E. MORIN.
