Marco: Basically, as Todd says. (Thanks, Todd!).
Below is a variant of the last box in my earlier reply, but simplifying the
caller from a list to a string:
----------
bundle agent caller_N
{
vars:
# construct data ending with:
"user_a" string => "ua_k1_value;
"user_a" string => "ua_k2_value;
methods:
# Note that we pass the fully-qualified name of our assoc. array.
possibly_general::
"any"
usebundle => action_user_promise("caller_N.user_a");
}
bundle action_user_promise(v)
{
# use "$(v)" etc.
}
----------
Note, importantly, the "caller_N" component to the variable in the "usebundle"
line. As I understand it, what this does is to pass its argument as a simple
string "caller_N.user_a", which just happens to be the fully-qualified name of
the caller's variable. We then write the called bundle (action_user_promise),
knowing that this incoming "v" argument (at first sight a string) is actually
an associative array.
The well-established example of this in the standard library
"cfengine_stdlib.cf" is "set_variable_values".
