Hi Mat,
thanks for your reply.
I think this code could be the key to some missing features.
Hi everyone
For my purposes it would be good to be able to set different start and
ending marks, I guess this should be possible.
I tried to understand and change the cherrypicker Macro
(http://cherrypicker.tiddlyspot.com/#CherryPicker) replacing the $mark$
by $start$ and $end$.
I understood some things, some are beyond my knowledge.
My result crashes I think due to problems with the recursion. (What
means +[first[]]?)
I made a commented version of the macro,
For those willing to help who don`t know the cherrypicker, the aim is to
list the sections between $start$ and $end$.
So thanks for help
Jan

Hi Jan. I'd love to help you but I feel I must prioritize the
TWederation stuff - sorry.
FYI, I started refactoring the CherryPicker macro some time ago but
hit a roadblock due to the limited possibilites to work with strings
and substituting sub-strings in a controlled way, using wikitext. Hope
to get back to it because I have some really cool stuff I hope to make.
If you are experimenting yourself, and it's not obvious already, the
CherryPicker basically traverses through the text in a recursive way
until it hits the "markers" where it cuts and then continues after the
end marker. At least I think this is what it does... it was a while
ago ;-)
