Just sharing this in case it helps someone.

use case:
As part of the process of migrating old plone sites, this allows you to generate the versions of eggs that are known to work.

Background
============
The extract-eggs-from-instance-and-pin.py script is used as part of migrating old plone sites.
This allows me to generate the versions of eggs that are known to work.

It gives you a good starting point, but don't stick to it religiously. You'll find that you may need to remove the zc.buildout and setuptools pins for example.

WARNING! This is a "works for me" script.

        items = [item.strip() for item in line.split('/')]
        egg = items[-1].replace("',","")
        if egg.endswith("egg"):
           eggparts = egg.split('-')
           print "%s=%s" % (eggparts[0],eggparts[1])

You can also dump the versions with this command:

github.com

plonegovbr/portal.buildout/blob/master/development.cfg#L120


eggs =
    ${instance:eggs}
    plone.app.robotframework[reload]


[versions-dump]
# keep versions.cfg file for closed production environments updated
recipe = plone.recipe.command
file = ${buildout:directory}/etc/versions.cfg
command =
    echo "# THIS FILE IS GENERATED AUTOMATICALLY\n[versions]" > ${:file}
    bin/buildout annotate versions | tail -n +6 | grep "= " | sed 's/= / = /' | sort >> ${:file}
update-command = ${:command}


[node]
recipe = gp.recipe.node
version = 8.11.2
npms = npm yarn
scripts = npm yarn


[staticresources-agenda]
recipe = sc.recipe.staticresources
