The micro-language should provide a limited number of
variables to use on the conditions:
python_version = sys.version
sys_platform = sys.platform
If we adopt such a micro-language (I'm reserving judgment until I've
had more time to read the relevant PEPs carefully), I'd rather see the
names match what's in the Python runtime more closely, probably only
avoiding the call syntax.
We could do that as well, yes.
+1 on close names + no call syntax
but, notice that "python_version" here is: "%s.%s" %
sys.version_info[0], sys.version_info[1]
thats why we came up with that name, to disinguish it from sys.version
(that contains more stuff)
I think we do need the full version here, so perhaps using
sys.version.split()[0] would be better or simply the full
version string and then have conditions use >=, <=, <, >
only (ie. not =, since that would likely never match).
Notice that for the comparisons >, < to work, that requires more than string
comparisons in case we provide the ability to work with rc versions, because:
'2.6.3rc4' < '2.6.3'
False
We said earlier that we could use sys.hexversion to handle this, but otherwise,
at least for the Python version, we can use the StrictVersion() class
from Distutils,
*But* we ended up thinking that it would be better for the first version to keep
just "==", "!=", "in" and "not in" operators and a MAJOR.MINOR string.
These are enough just to compare strings, on a limited number of
versions for Python.
I thought the plan was to stick with major.minor and "==", "!=", "in"
and "not in" until PEP 386 was accepted, then switch over to having all
versions (including Python's) be some sort of Version object, at which
point we can have richer version comparisons, with all of the existing
uses being compatible.
