[Mason-devel] HTML::Mason::Exception handler <%method> ?

[C.J. Adams-Collier]

Hey folks,

We would like to start throwing and handling exceptions to determine the
service responsible for causing content problems.

Is it possible to specify a <%method> as a catch block for any
exceptions thrown within a given lexical scope?

Cheers,

C.J.

If by "lexical scope" you could mean "component",
then there's HTML::Mason::Plugin whose end_component_hook
can access exceptions thrown during the eval of a component
(or at the end_request_hook level).

For a more general "lexical scope", I guess you could wrap
eval { ... } around the scope and send any $@ to the %method
in the normal ways.

D'oh. I realized that shortly into writing it, subscribed to the list
and then forgot to change the to: line. My apologies.
