You cannot have the characters [ and ] inside a literal operand to a filter operator. The workaround is to define the regular expression as a variable and then use the variable as the operand. Pseudo code below. \define myregexp() ((?:.*\s)|^)([a-zA-Z0-9_]+$) \define compare-by-last-name-with-character-class() [<currentTiddler>search-replace:i:regexp<myregexp>,[$2, $1]] \end -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
