[tw5] Re: Intersection of two filter runs
Here's a trimmer version of the previous macro. It seems to work and doesn't require calling a macro on each list item: \define f1() [enlist]-[enlist] \define f2() [enlist]-[enlist] <$vars x="1 2 3 4 5" y= "2 7 9 3" > <$list filter="[enlist] [enlist] -[subfilter] -[subfilter]" variable=item> <> I think to find out which version is more efficient you'd have to load up a huge array and time the difference. With only a handful of items, the priority is which code is easiest to read and fix later on ? -- Mark On Wednesday, March 13, 2019 at 10:00:07 PM UTC-7, Mohammad wrote: > > Thanks Mark! > > Just one more question: What is your opinion on the intersection code > above? > > In real world!

[tw5] Re: Intersection of two filter runs
Thanks Mark! Just one more question: What is your opinion on the intersection code above? In real world! In Tiddler Commander I have a filter search to filter some tiddlers based a certain criteria and then I have a checkbox widget to select among those tiddlers! If I change the filter search (using textbox), I have still the selected tiddlers using checkbox there! So, I need extra step to determine if the selected tiddlers by checkbox widget are existed in the new filter search. That the reason I have to find intersection. Thank you again Mark! --Mohammad On Thursday, March 14, 2019 at 8:09:52 AM UTC+3:30, Mark S. wrote: > > I don't think it qualifies as a true logical operator the way *run* and > *-run* do.

I don't think it qualifies as a true logical operator the way *run* and *-run* do. I think of it more of as a funnel > operator, telling the next run to use the previous run as input.

[tw5] Re: Intersection of two filter runs
Hi again, I tried to do something like this \define intersect-item(filter, item) <$list filter="[<__item__>] -[subfilter<__filter__>]" variable="result" emptyMessage=<<__item__>> > \end \define intersect(flt1, flt2) <$list filter=<<__flt2__>> variable=item > <$macrocall $name="intersect-item" filter=<<__flt1__>> item=<> /> \end <$vars x="7 8 -1 -3 9 11" y= "1 2 3 4 5 6 7 8 9" > <$macrocall $name=intersect flt1="[enlist]" flt2="[enlist]" /> The procedure is, I check every item in filter2 output to see if it is in filter1 output. If so, I display it, if not, I ignore it! I am not sure if the code is optimize and according to TW rules and standard. Application: I have two set of tiddlers, for example those have property1 and those have property2. I want to show tiddlers have both properties! Give me your comments. --Mohammad On Wednesday, March 13, 2019 at 10:44:24 PM UTC+3:30, Mark S. wrote: > > > You may not like this version, but it seems to work: > > <$vars > x="1 2 3 4 5" > y= "2 7 9 3" > f1="[enlist]-[enlist]" > f2="[enlist]-[enlist]" > > > <$list filter="[enlist] [enlist] -[subfilter] -[subfilter]" > variable=item> > <> > > > > I worked the logic out with a venn diagram. > > I was pleasantly surprised that the <> brackets were interpolated two > levels down. > > Thanks! > -- Mark > On Wednesday, March 13, 2019 at 9:47:09 AM UTC-7, Mohammad wrote: >> >> I have a code like below >> >> <$vars >> x="1 2 3 4 5" >> y= "2 7 9" >> > >> <$list filter="[enlist] +[enlist]" variable=item> >> <> >> >> >> >> Produces >> 2 7 9 >> >> I expect +run to logically AND the filter output, means those item are in >> both filter run or the INTERSECTION of two run >> e.g. *2* >> >> How can I implement this? >> >> --Mohammad >> >> More information >> - https://ooktech.com/jed/ExampleWikis/FilterLogicExamples/ >> - http://tobibeer.github.io/tw/filters/#Filter%20Examples >> > -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
