It's explained in the commit, but seems like upload.py ignores commit messages. Basically setup tools think that "2.0.0a0" < "2.0" so it couldn't find my development moin2 install. This fixes it.

MoinMoin/auth/__init__.py:448: # logging.debug("session started for user {0!r}".format(userobj)) This is not part of the plugin system change and I'll cherry pick this out and commit it as bugfix. Basically sometimes userobj doesn't contain attributes needed for userobj.__repr__() (such as itemid and name) when that logging statement is called and that makes the whole system crash. Also this somehow didn't let me log in at all without crashing or raising exception, no idea why that happened, but this comment fixed it. Anyhow it's a separate issue.

These are the two functions which are added to jinja2 template globals so they can be accessed from templates using "theme" and "theme_static" functions. They're global because they're accessible in all templates. Any suggestions for better name? http://codereview.appspot.com/6344080/diff/11001/MoinMoin/themes/__init__.py#...

When templates are looked up, it first tries to look up theme template which is named according to this format "_themes/{theme}/{template}" so we're removing "_themes" part and we try to extract theme and template from the rest of the string. Other case is when the string doesn't start with "_themes", one might be referring to specific theme directly. If all fails and it can't look up the theme, the app will use next Loader in chain which typically is the default one which loads from default templates. I could change this loader to automatically fail to default and that way eliminate the need to chain loaders in most cases. http://codereview.appspot.com/6344080/diff/2004/MoinMoin/themes/__init__.py#n...

This also is the exception which Loaders usually raise so to maintain compatibility with other code which might interact with loaders I use TemplateNotFound exception which at the end is also correct. Loaders are not aware of themes, all they care about is mapping template names to template paths. http://codereview.appspot.com/6344080/diff/2004/MoinMoin/themes/__init__.py#n...

I agree, I would probably do this a bit differently, but I didn't want to break anything already in templates. Not quite sure if we need the two cases here but: 1st use case - You can just use theme("sometemplate.html"), which will try to look up theme template (using _theme) and then fall back to inbuilt templates 2nd use case - You can link directly to the theme template using string such as "themename/template.html". This basically allows you to use other template files even if user has different template selected.

If I do it in init and plugin overwrites init it won't work unless they use super().

I need to somehow filter out all the ABCs, right now I just compare all the classes to classes declared in this file (All of them are ABCs).
