Hm.... What I always do, is I start yaws in intractive mode (yaws -i or
sudo yaws -i) and then do all the erlyweb stuff from there. Then I see
all the io:format messages just fine
How do you attempt to do the redirect? Since before_call should return a
tuple in the form of {NewFunc, Params}, a redirect to a different
function may probably look like this (this is untested, so there could
be mistakes):
-compile(export_all).
before_call(call_1, A) ->
{new_func, A}; %% substitute function, no visible redirect
before_call(call_2, A) ->
{call_2, A}; %% call the actual function,
%%let the function do a redirect
before_call(call_3, A) ->
{new_func_3, A}. %% call a substtute function,
%% let it do a redirect,
%% same as above, with a new name
new_func(A) ->
do_some_stuff,
{data, ok}.
call_2(A) ->
{ewr, some_controller}.
new_func_3(A) ->
{ewr, some_other_controller}.
As for a wiki, that'd be grand :) The only problem is that it should
really be an Erlang-based wiki to show off the ErlyWeb... Or, probaby,
some interim wiki...
