I don't think that we have a core substring filter, the only way that I know of to do it is by some creative usage of the split, butfirst, first and join operators.
Which is probably not a practical usage, but it is possible. \define subStr(input, start, end) <$set name=len filter='[<__end__>subtract<__start__>]'> <$list filter='[<__input__>split[]butfirst<__start__>first<len>join[]]'> </$list> </$set> \end <<subStr """hello""" 1 4>> it contains the character at the index given for start and not the character given for end. And uses 0-based indexing. Probably not useful, but I believe that is the current state of substrings in the core. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
