Need help with an improvement for the Subsume plugin

#1

Hi everyone

H La Vallee came up with an improvement to the Subsume plugin (The Subsume Plugin — Turn links into sliders!), so that it takes the caption field of a subsumed tiddler into account, and displays that in the details summary element rather than the tiddler title.

He (or maybe she? I don’t know what the H stands for, and don’t want to make assumptions) kindly gave me these snippets:

Here's my modified $:/plugins/giffmex/subsume/macro :

\define subsume(tid:"") <details><summary><$list filter="[[$tid$]has[caption]then{$tid$!!caption}else{$tid$!!title}]"><$text text=<<currentTiddler>>/></$list><$link to="$tid$">&nbsp;&nbsp;*&nbsp;</$link></summary><span class="indent1"><$transclude tiddler="$tid$" field="text" mode="block"/></span></details>

and the corresponding $:/plugins/giffmex/subsume/macro/subsume-edit :

\define subsume-edit(tid:"") <details><summary><$list filter="[[$tid$]has[caption]then{$tid$!!caption}else{$tid$!!title}]"><$text text=<<currentTiddler>>/></$list>&nbsp;<$button class="tc-btn-invisible"><$action-sendmessage $message="tm-edit-tiddler" $param="$tid$" />&nbsp;^^{{$:/core/images/edit-button}}^^&nbsp;&nbsp;</$button></summary><span class="indent1"><$transclude tiddler="$tid$" field="text" mode="block"/></span></details>

They work great, generally, but tiddler titles that end in ! break them. He wasn’t sure how to fix it, so he recommended asking here.

I do like the improvement of incorporating the caption field when there is one. Can anybody help with whatever little tweak it needs?

Thanks in advance for your help. Blessings, Dave

There no need to use has[caption]. Instead, just use get[caption], which only “returns” a value if the caption field has a non-blank value.

To display the caption or title as plain text, you can use the $text widget, like this:

<$text text={{{ [<__tid__>get[caption]else<__tid__>] }}}/>

Alternatively, you can use the $view widget with fallback content, like this:

<$view tiddler=<<__tid__>> field="caption">
   <$view tiddler=<<__tid__>> field="title"/>
</$view>

and if you want the caption or title to be wikified, use the $transclude widget:

<$transclude tiddler=<<__tid__>> field="caption">
   <$transclude tiddler=<<__tid__>> field="title"/>
</$transclude>

hi, this is H!
your solution using $view is great! It passed a test of using >>"""!! as the caption :slight_smile:
I was not aware of the syntax with underscores but it seems like they are a lot more versatile than the textreference method…

with that, the macro is now:

\define subsume(tid:"") <details><summary><$view tiddler=<<__tid__>> field="caption"><$view tiddler=<<__tid__>> field="title"/></$view><$link to="$tid$">&nbsp;&nbsp;*&nbsp;</$link></summary><span class="indent1"><$transclude tiddler="$tid$" field="text" mode="block"/></span></details>

and subsume-edit is:

\define subsume-edit(tid:"") <details><summary><$view tiddler=<<__tid__>> field="caption"><$view tiddler=<<__tid__>> field="title"/></$view>&nbsp;<$button class="tc-btn-invisible"><$action-sendmessage $message="tm-edit-tiddler" $param="$tid$" />&nbsp;^^{{$:/core/images/edit-button}}^^&nbsp;&nbsp;</$button></summary><span class="indent1"><$transclude tiddler="$tid$" field="text" mode="block"/></span></details>

thanks much for your help and for Dave for the great plugin :slight_smile:

Hi everyone

Thank you @Scribs for the recommended update to the Subsume Plugin, and to @EricShulman for the tweak to make it work correctly.

I have updated the Subsume plugin site and added instructions. See The Subsume Plugin — Turn links into sliders!
