I propose that buildout-versions get incorporated into buildout in the following way:
OK, proposal 1 wasn't accepted. Here's another stab:
Proposal 2 ----------
1. The ``allow-picked-versions`` option gets a new allowed value of ``show``. if there are unpicked versions and this option is set to ``show``, then picked/unpinned versions are reported in a way suitable for copying into a versions section, presumably with the same format used by buildout-versions today.
2. New buildout option: ``update-versions-file``. This takes a path (relative to buildout directory) of a file to update with any unpinned versions (in a manner roughly the same as buildout-versions does today).
3. New buildout option: ``python-version`` that restricts the Python version, with the same semantics as buildout-version provides now.
+1
4. Change: develop eggs found in the buildout's develop-eggs directory will be used even if their version conflicts with a pinned version.
This is the current behaviour you get with buildout-versions and it makes me a little nervous but I've never had the will to fight it and it is useful... But, most packages being developed do have a version in their setup.py (as an aside, what does buildout do with non-develop packages that don't specify a version?) and so it feels like the semantics would be cleaner if we just made everything work the same way when it came to versions.
5. In buildout 2, The default value of the versions option will be "versions", rather than being unset. This will allow users to omit::
version = versions
from their buildout section.
6. To make it a little easier to supply buildout versions on the command line, make buildout the default section for command-line options, so::
update-versions-file=versions.cfg
or::
allow-picked-versions=show
would be allowed. (They are rejected now.)
