I've been into toying with run prefixes for my filters, to see what I can now do with them.
I've been able to have an equivalent of "if not A then B" but I've not been able to get "if A then B". the + or :and prefix is not a logical AND at all but just a way to replace all currents stuff in the pipe with new contents. Part of the problem is I can't produce NOT A. I mean, see this example: {{{ cobalt great gaz :filter[split[]match[r]] +[!is[blank]then[]else["great" void]] ~Expected }}} {{{ cobalt fox gaz :filter[split[]match[r]] +[!is[blank]then[]else["fox" void]] ~Unexpected }}} The only output is "fox" void. I expected that the first filter output be Expected. As a kind of check with {{{ cobalt great gaz :filter[split[]match[r]] ~Expected }}} {{{ cobalt fox gaz :filter[split[]match[r]] ~Unexpected }}} the output is great Unexpected which is totally what we thought we should have. The same also happens with cobalt great gaz :filter[split[]match[r]] +[!is[blank]] ~Expected }}} {{{ cobalt fox gaz :filter[split[]match[r]] +[!is[blank]] ~Unexpected }}} Again, that's OK. Maybe that's because [] is not a blank input? But {{{ [[]] +[!is[blank]then[Full]else[Empty]] }}} does indeed output Empty as expected so I'm really confused now... BTW, in real life, in "if A then B" my B is not a constant, in which case I would have used [A]!is[blank]then[B] but a complex run. I know I can have a function or variable as my B to get around the difficulty, but that is not what I want to do here. -- Jean-Pierre -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
