How to filter tiddlers comparing title prefixes with system date?

[@magasine]

Hi,

I have a question!

My TW has titled tiddlers with a prefix that references dates, as in the examples below:

20180115 - Content of the Past

20180228 - Present Content

20180315 - Content of the Future

I have a macro (StartupActions: http://ooktech.com/jed/ExampleWikis/StartupActions/) that is turned on for page load, directing the fill of fields of certain tiddlers, with an appropriate status: past, present or future.

Question:

How can I build a filter that can display each of these conditions, past, present, and future, based only on the prefix analysis contained in the titles, compared to the system date I get from the macro << now YYY0MM0DD >>

My code:

\define tempNodeColor()

<$set name="hoje" value=<<now YYYY0MM0DD>> >

<$set name="tagMesM" value=<<now YYYY-0MM>> >

 <!-- ADICIONA COR GREEN AO NODE DO MM E TAG ANO-MES DO MES CORRENTE, CASO NÃO EXISTA -->

<$list filter="[all[]prefix<hoje>]">

<$action-setfield $field="_tgr_node_class_add" $value="my-green-node" />

<$action-listops $field=tags $subfilter='+[append<tagMesM>]'/>

</$list>

<!-- ADICIONA CORES AO NODE DO MM PARA CONTEÚDOS TAGEADOS COM EVENTOS-REALIZADOS E EVENTOS-REALIZANDO -->

<$list filter="[tag[Past]]">

<$action-setfield $field="_tgr_node_class_add" $value="my-gray-node" />

</$list>

<$list filter="[tag[Present]]">

<$action-setfield $field="_tgr_node_class_add" $value="my-green-node" />

</$list>

</$set>

</$set>

\end

<<tempNodeColor>>

It would be better to put your date (in TW date format) in it's own field. Then use the day and sameday filter operators to determine future/past/present.
