Please help with a "complex" then else filter

[Tony K]

i have this filter

       [regexp:title<pattern>] [regexp:text<pattern>] -[all[current]backlinks[]] -[is[current]] -[tag[hide]] -[is[system]]

and it is working fine, however if I want to make it a "true"/ "false" variable

    <$vars    isFreelink = {{{ [regexp:title<pattern>] [regexp:text<pattern>] -[all[current]backlinks[]] -[is[current]] -[tag[hide]] -[is[system]]then[true]else[false] }}} >

it is giving me a syntax error

Is this multi - parts filter supported with the if then else?

thank you

try:

{{{ [regexp:title<pattern>] [regexp:text<pattern>] -[all[current]backlinks[]] -[is[current]] -[tag[hide]] -[is[system]] +[then[true]else[false]] }}}

Since your first filter works, I guess it is not the problem but just to make sure:

• I don't think there can be spaces next to the equal sign. Or I just learned something new.
• There are some differences between the SetWidget and the VarsWidget where the former is somewhat more powerful. Can't recall details. Anyway, you could see if it happens to work using the SetWidget instead.

Syntax gremlins (they bug me too). "Runs" (sequences of filter operators) should be wrapped in square brackets, so

-[is[system]]then[true]else[false]

Should be

-[is[system]then[true]else[false]]


But I'm not sure that's going to do what you want.... AAah, Saq found the syntax, good.

Best,

I believe saqs form is nessasary because it must be a seperat run to operate on all tiddlers resulting from all previous runs not only the
[is[system]here]

Do tell me so if I got it wrong.
