Does Buildout support value substitution in the extends
option of the buildout
section?
For example, this example.cfg
doesn't extend with base.cfg
:
[config]
base = base.cfg
[buildout]
extends =
${config:base}
parts =
buildout -c example.cfg annotate
My goal is to send the file-to-extend as a parameter from the outside like this:
buildout config:base=base.cfg -c example.cfg annotate
I tried to merge the buildout:extends
from the outside; but that doesn't work either:
buildout buildout:extends+=base.cfg -c example.cfg annotate
No, extends
doesn't support value substitutions, unfortunately. The current implementation processes buildout.extends
before variable substitution can take place.
There is an existing feature request open for this: #39 No variable substitutions in extends.
I generally create a local.cfg
file first, perhaps from a template, and run buildout -c local.cfg
. That'd be the kind of place I'd put custom extends configuration.
