If you wikify (render) the contents before stashing in the tiddler, you'll prevent the recursion. In the following I'm using "HelloThere" from TiddlyWiki.com
\define addtimestamp(tiddler) <$set name="curtext" tiddler=$tiddler$ > <$set name="ts" value=<<now [UTC]YYYY0MM0DD0hh0mm0ssXXX>> > <<ts>> <<curtext>> </$set> </$set> \end <$button>test <$wikify name=out text=<<addtimestamp HelloThere>> > <$action-setfield $tiddler="HelloThere" text=<<out>>/> </$wikify> </$button> On Friday, January 8, 2021 at 5:25:27 AM UTC-8 Petri M. wrote: > Oh apparently my <<addtimestamp test2>> tries to put the *entire > contents *of the addtimestamp macro into the test2 tiddler.
