Why is it needed?  That would need a comment.  :-)  Even better if we
can achieve the same effect without defining this search path.

Also no need for the leading slash in ‘files’.

Please return #t.

dtc has Python bindings and we build them.

The u-boot-tools tests use them (nothing else does).

I'll add a comment.

>  Even better if we

Sure, I guess.  If you install dtc into your profile it won't work then though.

Also, do you think we should try to extract the Python bindings into its own
package?

Okay.

invoke does :)

We can add another one, though.

But then we do not need a search path definition in dtc itself; the one
in Python is enough.  Or am I missing something?

I think there are two possible situations:

  1. dtc provides Python bindings that are useful to Python
     programmers.  This is addressed by having both Python and dtc in
     the same profile, in which case PYTHONPATH is automatically
     defined.  Nothing special to do.

  2. dtc is itself written in Python and needs to access its own
     Python code.  In that case we should wrap the ‘dtc’ command such
     that PYTHONPATH contains the right thing.

Does that make sense?

Not necessarily, it probably doesn’t take up much space.

There's a libfdt.py, provided by the dtc package, and u-boot-tools
tests use it.

Right now, we're not necessarily installing libfdt.py into python (?) or the
profile or anything.

Like u-boot-tools has somewhere (in its unit tests):

  #!/usr/bin/env python3
  import pylibfdt

And dtc provides

  libfdt.py

which could be useful for Python programmers, too.

Yes.  But in this case u-boot-tools uses libfdt.py when building (testing) itself.

OK.  If u-boot-tools has both Python and dtc as inputs, then PYTHONPATH
is correctly defined, isn’t it?

> profile or anything.

So we should make sure dtc installs libfdt.py in $prefix/lib/python2.7/….

Does that make sense?

Hmm, then I don't understand how native-search-paths works.

I thought native-search-paths would just add $package/$path for the current
package--but it seems guix uses it as a pattern in all packages, not just
the package that specified it.

It indeed works if I remove native-search-paths from dtc, so I've pushed it
without.

Hello,

The search path spec is attached to the package that “owns” the given
variables.  So python has a spec for PYTHONPATH, Guile has a spec for
GUILE_LOAD_PATH, and so on.

Then, if you have both python and a python package in the same profile,
the machinery automatically defines PYTHONPATH according to the spec.

Cool, thanks!
