Re: [tw5] How to use the $set widget properly with a "not missing" and "empty" filter?

Hi S.S, This is great! You can visually and interactively play with $set and see the result! Thank you On Friday, April 5, 2019 at 4:50:39 AM UTC+4:30, S. S. wrote: > > > The set widget is very useful for choosing between multiple options. > Understanding the logic of what combinations of the $s

Re: [tw5] How to use the $set widget properly with a "not missing" and "empty" filter?

S S I often use a variation of this when making my own macros to allow it to use current tiddler or another if provided. Basically it provides a default of the current tiddler \define mymacro(tiddlername) <$set name=selected-tiddler value="$tiddlername$" emptyValue=<< currentTiddler>> > Action:

Re: [tw5] How to use the $set widget properly with a "not missing" and "empty" filter?

The set widget is very useful for choosing between multiple options. Understanding the logic of what combinations of the $set widget's attributes produce the desired outcome is essential to using it for such a requirement. The discussion above was quite a revelation. Here's a possible use. If

Hi SS That’s great, thank you. > Testting shows: If there is a value attribute & no emptyValue attribute, the > value is returned irrespective of the filter's result. I can confirm that behaviour, and I think it’s a bug. But… I’m not 100% sure that we should fix it; it might be better just to

I have copied and pasted from Eric's post - and added in some from Jeremy's post, and a few of my own observations. I am sure this is still not perfect. I hope this formats properly. Google Group's functionality and reliability, and this posting editor must be one of the weakest links in their

Re: [tw5] How to use the $set widget properly with a "not missing" and "empty" filter?

Hi SS The logic used by the set widget to determine the result assigned to the variable is as follows: 1. If the "tiddler" attribute is present and not blank, then: 1a. If the "subtiddler" attribute is also present and not blank, then get the subtiddler from the specified tiddler, otherwise jus

[tw5] How to use the $set widget properly with a "not missing" and "empty" filter?

Within a macro, I am trying to determine if a parameter is empty, and then set a variable based on knowing that it is empty. I came across the Google Group post from a last month: Check the Blank Macro parameter \
