That's true, however, routes aren't full regular expressions, two
restrictions apply:
- regular expressions in route patterns must be enclosed in parentheses
- non-matching pre and postfixes must be outside of the curly braces
that wrap the actual pattern
I believe <route pattern="^/products/view/(id:\d+)$" /> is relatively
straightforward even for someone with only basic knowledge of regular
expressions. all you have to know is that they may only occur in
parantheses, and that the name of the parameter that should contain
the match is at the beginning, followed by a colon.
(foo{id:\d+}bar) is a special syntax by agavi, the curly braces are
used as delimiters for pre and postfix. for "foo23bar", this example
puts only "23" into the parameter "id". that's why you hae to set the
defaults with curly braces, because the pre and postfix could also be
a regular expression, and agavi must know a constant value to use
when generating urls (since you cannot set the pre and postfix from
gen(), only the "inner" value).
