# default_application, default_controller, default_function
# are used when the respective element is missing from the
# (possibly rewritten) incoming URL
#
default_application = 'mobileblur'    # ordinarily set in base routes.py
default_controller = 'default'  # ordinarily set in app-specific routes.py
default_function = 'index'      # ordinarily set in app-specific routes.py

# routes_app is a tuple of tuples.  The first item in each is a regexp that will
# be used to match the incoming request URL. The second item in the tuple is
# an applicationname.  This mechanism allows you to specify the use of an
# app-specific routes.py. This entry is meaningful only in the base routes.py.
#
# Example: support welcome, admin, app and myapp, with myapp the default:


routes_app = ((r'/(?P<app>welcome|admin|app)\b.*', r'\g<app>'),
              (r'(.*)', r'myapp'),

# routes_in is a tuple of tuples.  The first item in each is a regexp that will
# be used to match the incoming request URL. The second item in the tuple is
# what it will be replaced with.  This mechanism allows you to redirect incoming
# routes to different web2py locations
#
# Example: If you wish for your entire website to use init's static directory:
#
#   routes_in=( (r'/static/(?P<file>[\w./-]+)', r'/init/static/\g<file>') )
#

routes_in = ((r'.*:/favicon.ico', r'/examples/static/favicon.ico'),

# routes_out, like routes_in translates URL paths created with the web2py URL()
# function in the same manner that route_in translates inbound URL paths.
#

routes_out = ((r'.*http://otherdomain.com.* /app/ctr(?P<any>.*)', r'\g<any>'),

# Error-handling redirects all HTTP errors (status codes >= 400) to a specified
# path.  If you wish to use error-handling redirects, uncomment the tuple
# below.  You can customize responses by adding a tuple entry with the first
# value in 'appName/HTTPstatusCode' format. ( Only HTTP codes >= 400 are
# routed. ) and the value as a path to redirect the user to.  You may also use
# '*' as a wildcard.
#
# The error handling page is also passed the error code and ticket as
# variables.  Traceback information will be stored in the ticket.
#
# routes_onerror = [
#     (r'init/400', r'/init/default/login')
#    ,(r'init/*', r'/init/static/fail.html')

def __routes_doctest():
    '''
    Dummy function for doctesting routes.py.

    Use filter_url() to test incoming or outgoing routes;
    filter_err() for error redirection.

    filter_url() accepts overrides for method and remote host:
        filter_url(url, method='get', remote='0.0.0.0', out=False)

    filter_err() accepts overrides for application and ticket:
        filter_err(status, application='app', ticket='tkt')
