求助：生成随机数

[一块石头]

有哪些生成随机数的筛选器操作符，宏，微件？

[FSpark]

这里有纯Wikitext实现的，以当前时间为种子的生成器： https://talk.tiddlywiki.org/t/random-tiddler-button/4653

\define randomTiddler(filter, label)
<$let seed=<<now XXX>>
      minNum  = 1
      maxNum  = {{{ [subfilter<__filter__>count[]] }}}
      randNum = {{{ [<maxNum>subtract<minNum>multiply<seed>divide[999]add<minNum>round[]]  }}}
>
<$link to={{{ [subfilter<__filter__>nth<randNum>] :else[subfilter<__filter__>first[]] }}}>$label$</$link>
</$let>
\end
