Right; I believe the "Nuke-5.1v6-customizing.pdf" documentation cites
this exact example [sic]:
----
def filenameFix(filename):
if platform.system() in ("Windows", "Microsoft"):
return filename.replace("/SharedDisk/", "p:\")
else:
return filename.replace("p:\", "/SharedDisk/")
return filename
----
..which appears to show how to replace e.g. "/SharedDisk/foo" <-> "p:\foo"
depending on the platform it's running on.
However, there's a few things wrong with that example I think; that backslash
after the "p:" needs to be protected, otherwise python will interpret it as an
escape character. Also, that final 'return filename' appears to be extraneous,
as there's no way that line will ever execute.
So I would suggest the following instead:
----
def filenameFix(filename):
if platform.system() in ("Windows", "Microsoft"):
return filename.replace("/SharedDisk/", "p:\\")
else:
return filename.replace("p:\\", "/SharedDisk/")
----
Another way to protect the backslashes would be to use:
r"p:\" # same as "p:\\"
This is pythons little way of protecting all characters between the
double quotes, the leading 'r' in front of the leading double quote
means "raw string", protecting the backslash from being mistaken
for an escape sequence.
An example that worked for a recent client who wanted to make sure
UNC style pathnames were used on windows, (eg. "/bart/foo" would become
"//bart/foo" on windows machines), I suggested they use:
----
import re
import platform
def filenameFix(filename):
if platform.system() in ("Windows", "Microsoft"):
return re.sub("^/*bart","//bart",filename)
else:
return re.sub("^/*bart","/bart",filename)
----
..the special regex ensuring that e.g. //bart doesn't become ///bart
