Django can work with Python 2 and 3 already, though changes may be required to how the Evennia code
|
|
|
|
|
uses it. Twisted has much Python 3 compatibility, but not all modules within it have been ported
|
|
|
|
|
yet. The
|
|
|
|
|
[twisted.python.dist3](https://twistedmatrix.com/documents/current/api/twisted.python.dist3.html)
|
|
|
|
|
module gives some information about what's ported, and I'm compiling a list of missing modules with
|
|
|
|
|
related bug reports which can be found below. The list is based on a search for import statements in
|
|
|
|
|
the Evennia source code, please add anything that's missing.
|
|
|
|
|
|
|
|
|
|
Part of this process is expected to be writing more tests for Evennia. One encouraging recent port
|
|
|
|
|
to Python 3 in Twisted is its Trial test framework, which may need to be used by Evennia to ensure
|
|
|
|
|
it still works correctly with Twisted on Python 3.

# "Strings"

|
|
Broadly (and perhaps over-simplified):
|
|
|
|

|
|
|
* Twisted [expects bytes](http://twistedmatrix.com/trac/wiki/FrequentlyAskedQuestions#WhydontTwisted
|
|
|
|
|
snetworkmethodssupportUnicodeobjectsaswellasstrings)
|
|
|
|
|
* Django [expects "" to be unicode](https://docs.djangoproject.com/en/1.8/topics/python3/#unicode-

|
|
|
|
literals)

|
|
|
|
2020-10-11 19:31:05 +02:00
|
|
|
I think we should use (roughly speaking) "" for unicode and b"" for bytes everywhere, but I need to
|
|
|
|
|
look at the impacts of this more closely.
