Variables in links

[Luis Gonzalez]

I can't find the way of adding a variable to a link:

Enter the code of the center: <$edit-text tiddler="$:/kewa/status" field="codcenter"/>

<$set name="themail" tiddler="Mail-codes" index={{$:/kewa/status!!codcenter}}>
[ext[mailto:<themail>]]

</$set>

What is the variables syntax in links????

I've tried with [ext[mailto:<<themail>>]], [ext[mailto:{{Mail-codes##<<themail>>]], [ext[mailto:$themail$]] and many others.

Maybe there are other ways but I'd say it's a typical macro case:

\define mylink() [ext[mailto:$(themail)$]]

<$set name="themail" tiddler="Mail-codes" index={{$:/kewa/status!!codcenter}}>

<<mylink>>
</$set>

Thank you!!

I've found other "tricky" solution with variables:

Enter the code: <$edit-text tiddler="$:/kewa/status" field="codcenter"/>

<$set name="the_mail" tiddler="Mail-codes" index={{$:/kewa/status!!codcenter}}>

<$set name="the_link" filter="[<the_mail>addprefix[mailto:]]">
<a href=<<the_link>>><<the_mail>></a>
</$set>
</$set>
