Evan,
That works like a dream. Thank you.
As you say "tiddlywiki-oriented functions" here are some that come to mind
I am trying to identify based on the current implementation
if then else or other logical operators to transclude a tiddler, or include
content.
For example hiding or displaying content based on logic from prior answers
or calculations.
I am currently building a couple of macros to provide buttons with the
ability to increment a date by N days, weeks months etc...
My Problem is ensuring the result not the formula is returned. I have
calculated using formulas the new date and still struggling to right this
back to the input date field.
I think this already possible I am just trying to workout how to do it, and
as simply as possible.
Here is a snipit that is not working.
\define commitdateaction(label,datefield,update)
<$button tooltip="Change $datefield$ to $update$" class="tc-btn-invisible
tc-tiddlylink" >
<$action-setfield $field="$datefield$" $value="$update$"/>
$label$
</$button>
\end
\define dateincrements(datefield,inc:"D W F M Q H Y")
<$set name=indate value="(= tw_date( {{!!$datefield$}} ) =)">
<!-- Main Loop -->
<$list filter="$inc$" variable=period>
<$list filter="[<period>prefix[D]]" variable=incperiod>
<!-- Day -->
<$set name=multiple value="1">
<$set name=label
value="(={{!!dateinc}}*<<multiple>>=)<<incperiod>>">
<$set name=newdate value="(=to_tw_date(add_days(<<indate>>,
<<multiple>>*{{!!dateinc}}))=)" >
<$macrocall $name="commitdateaction" label="<<label>>"
datefield=$datefield$ update=<<newdate>> />
</$set>
</$set>
</$set>
</$list>
....
<$select field=dateinc default='1'>
<$list filter='1 2 3 4 5 6 12' >
<option value=<<currentTiddler>>><$view field='title'/></option>
</$list>
</$select>
<!---
<$select field=dateincdec default='+'>
<option value="+">+</option>
<option value="-">-</option>
</$select>
Save and Provide Reset
-->
</$set>
<<newdate>>
\end
Regards
Tony
