regex is not working in top level app about webpy

I stumbled onto this as well. It appears that while local classes can use regex for URL handling, subapplication URL handling works only with literal strings. Looking in web/application.py around line 421 in the _match() function, the match test uses a startswith() rather than a regex function. This torpedos the design I've been working on, because I assumed (ass == me) that webpy would treat them consistently. So instead of doing URI rest calls that make sense to me:

• /container/{item-hash}
• /container/{item-hash}/summary
• /container/{item-hash}/detail

I have to put static discriminators first so they can get passed off to subapplication classes:

• /container/{item-hash}
• /container/summary/{item-hash}
• /container/detail/{item-hash}

I'm not sure what the purpose was in the inconsistency. When this was implemented, did something prevent treating local classes and subapplications differently? I don't see any comments that might shed light on the code.

Currently it only supports a hard-coded sub-app URL. For example, in your code.py:

urls = (
    "/(blog|Blog)", blog.app_blog,
    ...
)

it should be changed to something like this:

urls = (
    "/blog", blog.app_blog,
    "/Blog", blog.app_blog,
    ...
)

We have no plan to support regex for sub-application recently, sorry.
