===== Feed Triggers =====

==== Execute or not a Feed ====
===== MEL =====

[[http://mel.exalead.com/|MEL Playground]]

==== PLMA Data Table ====

=== Access/Display Data from subfeed ===
<code>
${foreach entry in entry.subfeeds['l4_date'].entries}
${entry.metas['l4_start']}<br/>
${/foreach}
</code>

=== Calculation on metas ===
<code>
${var:set("has_peca_kd", ?{entry.metas["edb_peca_kd"]?true:false})}
${var:set("has_state_end_prepare", ?{entry.metas["state_end_prepare"]?true:false})}
${var:set("has_edb_sw_notice_data_envio", ?{entry.metas["edb_sw_notice_data_envio"]?true:false})}
${if var:get("has_peca_kd") == "false" || var:get("has_state_end_prepare") == "false"}
${elseif var:get("has_peca_kd") == "true" && var:get("has_edb_sw_notice_data_envio") == "false"}
${entry.metas['local_dias_swn_not']}
${else}
${entry.metas['local_dias_swn']} ${/if}
</code>

==== Conditional display ====

Test if value from meta list contains a specific value
<code>
${var:set("display",0)}
${foreach facetclass in feeds['hit'].entry.metas['facet_classes']}
	${if (str:contains(facetclass, 'J1S'))}
		${var:set("display",1)}
	${/if}
${/foreach}
${var:get("display") == 1}
</code>

==== Trigger : Aggregation Builder ====

<code>
${var:set("ok_percent", 0)}
${var:set("ok_count", (category.aggrs["ok_perform"]))}
${var:set("total_count", (${category.count}))}
 ${if var:get("total_count") > 0}
  ${var:set("ok_percent", ((var:get("ok_count"))/(var:get("total_count")))*100)}
 ${/if}
${var:get("ok_percent")}
</code>

=== Feed Query ===
Do a query on each of the words of query and ecah of the comma separated words :
<code>
${if page.params['q']}
(
 ${foreach request in str:split(page.params['q'])}
  ${if str:contains(request, ",")}
   ${foreach val in str:split(",", request)}
    ${if loop.index != 0} OR ${/if}
    hpc_system_syetem_name:"${if str:substr(val, 0, 1) == "-"}\\${/if}${val}"
   ${/foreach}
  ${else}
   ${if loop.index != 0} OR ${/if}
   hpc_system_syetem_name:"${if str:substr(request, 0, 1) == "-"}\\${/if}${request}"
  ${/if}
 ${/foreach}
) OR ${page.params['q']}
${/if}
</code>

==== Split String into list ====
var array = new("java.util.ArrayList");
array = meta.marketing_text.split("\\|");
return array

==== Count of items in a list meta ====

<code>
var region_count=0;
for(v : bat_issue_region$l) {
  region_count += 1
};
return region_count
</code>

==== Split de metas ====
<code>var array = new("java.util.ArrayList");
for(v : meta.ownership$l) {
  var alSplit = new("java.util.ArrayList");
  alSplit = v.split("\\|");
  array.add(alSplit[0] + "_" + alSplit[1]);
}
return array</code>

==== Replace string in list ====
<code>
var array = new("java.util.ArrayList");
for(v : meta.history$l) {
  array.add(v.replaceAll("Create", "Preliminary").replaceAll("Assign", "Ready").replaceAll("Active", "In Work").replaceAll("Review", "In Review"));
}
return array
