Help needed to debug a filter run

<$let

   delink="\[\[.*?\]\]"

<$list filter="[enlist<imgs>]" variable="img">

I have images in my tiddlers in two formats

  1. [img[image-name]]
  2. {{image-tiddler-name.png}}

Some tiddlers have transcluded images, while some tiddlers have images in [img[]] format. I want to list all the images of both these formats and display them using a viewtemplate. But the above code is not listing the transcluded images.

    imgs={{{ [<myCur>get[text]search-replace:gi:regexp[\n],<sp>search-replace:gi:regexp<delink>,[]search-replace:gi:regexp<img1>,[@1@@]split[@1]prefix[@@]search-replace:gi:regexp<img2>,[.png@@]split[@@]regexp[(\.png$)]format:titlelist[]join[ ]] ~[<myCur>transcludes[]suffix[.png]format:titlelist[]join[ ]] }}}

This part of the code may not be correct. Can someone help ?

You need to define delink before imgs for it to be available as a variable.

I see 2 problems in your code:

  1. You use delink before defining it. You should move it up in the $let widget
  2. Your last filter run is an “else” filter run, so it won’t be evaluated unless other filter runs return no result. Remove the ~ at the start of the filter run.

Hope this helps

I think the culprit was the ~ . Its working once I removed the ~

I also needed to modify the code like this to make it work.

    imgs={{{ [<currentTiddler>get[text]search-replace:gi:regexp[\n],<sp>search-replace:gi:regexp<delink>,[]search-replace:gi:regexp<img1>,[@1@@]split[@1]prefix[@@]search-replace:gi:regexp<img2>,[.png@@]split[@@]regexp[(\.png$)]] [<currentTiddler>transcludes[]suffix[.png]] :and[format:titlelist[]join[ ]] }}}

But still the transcluded images are not being shown in the macy widget of macy plug in (which was the reason for creating this filter run). I have set up a demo here. Can you help me to find why its not working ?

I was having trouble following your filter, so I took the liberty of starting fresh. Try this out:

<$macy columns="6" breakAt="1300:5:15:15 940:3:10:10 520:2:5:5 400:1:1:1">
<$let
	imgfile="\.(jpg|png|gif)$"
	rb="]]"
	img="[img["
	imgs={{{ [<currentTiddler>] [<currentTiddler>transcludes[]]
		+[get[text]split<rb>] :map[split<img>last[]]
		+[regexp<imgfile>format:titlelist[]join[ ]] }}}
>
<$list filter="[enlist<imgs>]" variable="img">
<$button class="tc-btn-invisible item-container" tag="div" actions="""
<$action-spotlight
	$images=<<imgs>>
	$start=<<img>>
/>""">
<$image source=<<img>> class="item" />
</$button>
</$list>
</$let>
</$macy>

The “image” tiddler you were transcluding also uses the [img[...]] format, so it’s not enough to to simply use <currentTiddler>transcludes[] — this will return the title of the transcluded tiddler, not its text content. Instead, you’ll need to get the text of each transcluded tiddler as well as the <<currentTiddler>>, then apply the same split/regexp processing to extract any relevant image links.

This one works…thank you so much for the help.
Any idea why the images are vertically aligned instead of horizontal alignment?

Oops, that’s because I forgot to take out the extra line break after the $let widget. I’ll edit my code above.
