 did you know that you can transclude a field directly into a filter run in #TiddlyWiki ? To test this out I started a Photo Journal in my 🌱 [[digital garden]] I have a tiddler with the field `path` and I can print its contents using the transclusion notation: {{!!path}} 7 comments
the only photo journal I have right now is called Berlin (2008 May) and the image grid code is very concise and cool! <$list filter="[prefix[$:/images/photo-journal/berlin-2008/wide/]]"> This list widget is basically saying anything that starts with the path `…/berlin-2008/wide/` gets displayed. Notice the path is hard coded in this Photo Journal entry for Berlin (2008 May). But what if I want to display an excerpt of this Berlin collection on the index page of all the Photo Journals, like a little preview ? Back to our loop that pulls in all the items tagged [[Photo Journal]]: <$list filter="[tag[Photo Journal]!sort[date]]"> Within this list widget, I am going to open up a new list widget and copy the filter run above used in the Berlin photo journal. But there's a catch with the notation: transclusions within a filter run only accept single curly brackets 😮 So our sub-filter within the Photo Journal loop will now transclude the currentTiddler's field called `path` … with an offset of 6 + a limit of 3 (displaying the 7th 8th + 9th photos) <$list filter="[prefix{!!path}rest[6]limit[3]]"> photo journal preview in action! #tiddlywiki #digitalgarden #wiki #personalwiki #code #filter #transclusion |

{{!!path}} is a unique field which contains the system path of where #TiddlyWiki external image embeds are located.
I want Photo Journal to list all items tagged with [[Photo Journal]] and in reverse chronological order (date):
<$list filter="[tag[Photo Journal]!sort[date]]">
