fET question (&& or OR or??)

[Måns]

Hi
Can I do something like this?:
<<forEachTiddler where 'tiddler.tags.contains("A") && tiddler.data
("x") *OR* tiddler.data("y") '

The various clauses of fET are just bits of javascript, so you can use
the standard boolean operators:

AND = &&
OR = ||
NOT = !
with parentheses to control the order of evaluation.

Thus:
<<... where 'testA && (testB || testC)'... >>
means "A and B ... or ... A and C"
while:
<<... where 'testA && testB || testC'... >>
means "A and B ... or ... C"

enjoy,

Thanks . Just what I needed to keep on working :-)

Btw - if someone would like to se the looongest errorcode ever to
occur in a TW - then try to write
<<... where 'testA && (testB || testC)'... >> without the brackets!!
like this: <<... where 'testA && testB || testC'... >>
Astonishing how many words can be crammed into just one tiddler ;-)
