Depends on wxpython? #17

Closed TheChymera closed 6 years ago

TheChymera commented 6 years ago

As far back as 3.3.0 I notice imports like import wx? This doesn't sound right. I am in fact packaging your software in order to satisfy the dependencies of the newer wxpython versions. Are you aware of this circular dependency?

schollii commented 6 years ago

There is no circular dependency: the import wx is in the examples folder, maybe a couple places in the docs as example of use, they are meant for people who want to test/demo/sample with wx (since that is where pypubsub originated, there is a community of users there). There may be a dynamic introspection to determine if the 3.3.0 is being run from wx. If wx is installed, some special code is used. But there is no dependency on wx: if wx is present, pypubsub starts a little differently (in that release).

For the latest wxPython, please do NOT install 3.3. I no longer maintain 3.3, it was overly complicated due to compatibility constraints on the old wxPython. What exactly are you trying to do?

TheChymera commented 6 years ago

I want to provide wxpython 4.0.3 for both python2.7 and 3.{4,5,6}. As I understand, for as long as I want to support python 2.7 I will have to depend on pypubsub 3.3.0

Indeed. My point is you shouldn't slow down the future to support the past. Support both by import pypubsub33 vs pypubsub4, or something like that. I'm going to close this as I don't see this as being a pypubsub issue, it is a wxPython integration issue, but please don't hesitate to re-open or post on dev forum to discuss further. Thanks!
