Like I said, one can achieve 'and' and 'or' operations with
packages = pyopengl
packages = lxml >= 2.5
[dependencies mac python<=2.4]
packages = shinyxml
Translates roughly into the following python code:
dependencies = ["pyopengl"]
if sys.version <= '2.4':
if sys.platform == 'darwin':
So to me, configparser does provide a way to achieve a
sort of nested capability.
It just needs careful choices of headings.
Some people also use '-' to provide nesting. For
value = 1
[top - nested level 1]
value = 2
[top - nested level 2]
value = 3
These are accessed with 'top' + " - nested level %d" % levelno
To me this is all nesting.
I'm extremely interested to know of a practical example of
something related to packaging that we can't script for.
If you think of something, please post it. 'build' and 'test'
were too other keywords that were suggested to work in also.
I don't really want to do a build platform, only something for
the install platform. But here's how they could work.
[dependencies windows build]
packages = py2exe
[dependencies mac build]
packages = py2app
packages = unittestplus
