Soren,
Implied in my reply (not very well) was the lack of Quotes, I think "[" and
"]" would cause the string "format" to be misread. But as you say it is the
need to wikify first;
\define now-timestamp() <<now "[UTC]YYYY0MM0DD0hh0mm0ssXXX">>
<$wikify name=input text="<<now-timestamp>>">
<$button set="!!created" setTo=<<input>> >
Created Now
</$button>
</$wikify>
I have raised the possibility of a simpler way to annotate that a variable
be wikified before use.
In your case, without wikify the the created field is being setTo= <<now
[UTC]YYYY0MM0DD0hh0mm0ssXXX>> <!-- the exact string un-wikified -->
In the following case we do not use a macro containing a macro so we need
not wikify it first, the now macro is evaluated inline.
<$button set="!!created" setTo=<<now "[UTC]YYYY0MM0DD0hh0mm0ssXXX">> >
Created Now
</$button>
Display {{!!created}}
Contains {{{ [all[current]get[created]] }}}
Regards
Tones
