[Tsung] setdynvars problem

[Pablo Polvorin]

Hi, 
your plugin must implement its own add_dynparams/4, a signature like this:
add_dynparams(SubstFlag,DynData, Param, HostData) ->
    [
    here you define what the substitution rules are for the different 
    messages types of your plugin
    ]


If SubstFlag is false, (subst=false in the request) you probably want to return
the original message whitout any further processing:

add_dynparams(false, _DynData, Param, _HostData) ->
    Param;


if not, you must implement substitution depending on the message type, like: 
add_dynparams(true, 
              DynData, 
              #plcdtester_request{type=send, user=User, password=Password},
             _HostData) ->
 #plcdtester_request{type=send, 
                     user=*USER_FIELD_AFTER_SUBSTITUTION*, 
                     password=*PASSWORD_FIELD_AFTER_SUBSTITUTION*};

you can use ts_search:subst/2 for performing string substitutions on those
fields you want, just look how the others plugins behave.

cheers!
