Subject: Re: Implicit looping in an slist array

You can process slist array similar to string array
but inside agent bundle you need to assign it to local slist variable before
you can exapnd it , as expansion of global slist is not allowed
Here is a something that I am using , hope it helps
body common control
{
bundlesequence => { globalvars,
loblocalvars("globalvars.ibdefvars","globalvars.ibdefslvars"), main };
inputs => { "/var/cfengine/masterfiles/cfengine_stdlib.cf" };
version => "1.2.3";
}
#bundle common globalvars
bundle agent globalvars
{
vars:
"ibdefvars" string => "abra-ka-debra",
policy => "overridable";
"ibdefvars" string => "rotate",
policy => "overridable";
"ibdefvars" string => "5",
policy => "overridable";
"ibdefslvars" slist => { "string" ,"ping" },
policy => "overridable";
"ibdefslvars" slist => { "john", "doe" },
policy => "overridable";
classes:
}
bundle agent loblocalvars(defvars,slvars)
{
vars:
"param_keys" slist=> getindices("$(defvars)");
"ibvars[$(param_keys)]" string => "${${defvars}[$(param_keys)]}",
policy => "overridable";
"parm_keys" slist=> getindices("$(slvars)");
"ibslvars[$(parm_keys)]" slist => { "@{${slvars}[$(parm_keys)]}" },
policy => "overridable";
classes:
reports:
}
bundle agent main
{
methods:
"any" usebundle =>
array_slists("loblocalvars.ibvars","loblocalvars.ibvars","loblocalvars.ibslvars");
"any" usebundle => slists("loblocalvars.ibslvars");
}
bundle agent array_slists(s,n,v)
{
vars:
"v1" slist => { "@{${v}}" };
classes:
reports:
cfengine_3::
"string ${${s}} ";
"string ${${n}}";
"slist ${v1}";
}
bundle agent slists(s)
{
vars:
"sl" slist => { "@{${s}}" };
classes:
reports:
cfengine_3::
"slist ${sl}";
}
