Re: [tw5] Code that no longer works following upgrade to version 5.1.20

['mervin mecklenburg' via TiddlyWiki]

Thank you for the reply.

I have succeeded in resolving most issues related to my inappropriate use 
of the code snippet $(variable)$, which caused failures after the  the 
upgrade, but the there remains a couple of puzzles:

First, the following code continues to work:  <>.  Is 
this something that is harmless, or could continued use of this 
configuration  haunt me by failing after some future upgrade, and should I 
be weeding use of this configuration out of my present code?

Second, I'm having trouble finding a replacement for the use of 
$(variable)$ within a table of contents.  I have tried defining it in a 
macro; for example:

/define macroName(somevar)
<>
/end


<>


This approach works so long as the tag being passed has no spaces, but it 
fails when a space is present within the tag.  I have tried all of the 
tricks that I know that usually work when passing spaces within a 
variable.  For example, I have attempted to define the variable within an 
accompanying macro.  I have also tried defining the macrocall widget with a 
secondary macro.  So far, I have not found a solution.  Does anyone have a 
suggestion?  How do you define a variable for use in the 
<> when the variable is defined 
with a value that contains a space: for example, "this tag?"

The tiddler referenced by the transclude widget is the one that is used as a 
template. If you want to set a different currentTiddler for it to display then 
you can use the <$tiddler> widget wrapped around the transclude widget. (The 
{{tiddler|template]} syntax is a shortcut for a tiddler widget targeting the 
tiddler wrapped around a transclude widget targeting the template).

Re: [tw5] Code that no longer works following upgrade to version 5.1.20

[Michael Wiktowy]

Thanks for the explanation. I was wondering what had broken with one of my 
projects but didn't have the time to troubleshoot. This note saved me a 
great deal of head-scratching.

In this case, Mervin was using it in the context of a macro call. I can see 
how this can be worked around using <$macrocall name=<>/> in 
place of the <<>> syntax.

However, in my case, I was using it in a transclusion template like 
{{$(variable)$||some_custom_tag_pill_tiddler}}. In looking at the 
instructions for the full TranscludeWidget, I can do <$transclude 
tiddler=<> field="title"/> but is there a way to specify the 
template? I was able to workaround things by making a macro like you 
indicated containing the above {{||}} transclusion template but am I 
missing something in that the full transcludeWidget is not able to use a 
template tiddler? I did try adding a "template=" section but it didn't work.

/Mike

Re: [tw5] Code that no longer works following upgrade to version 5.1.20

[Jeremy Ruston]

Hi Mervin

I’m not sure without seeing more context but I think the problem may be this 
fix from v5.1.18:

https://github.com/Jermolene/TiddlyWiki5/issues/ 


Previously, `$(variable)$` substitutions were performed regardless of how the 
macro was defined (even if it was actually defined with the set widget). Now 
such substitutions are only performed for macros defined with the \def pragma.

Best wishes

Jeremy.

[tw5] Code that no longer works following upgrade to version 5.1.20

[TonyM]

Should the subfilter not include square brackets in it to deal with titles with 
spaces and other delimiters?

[tw5] Code that no longer works following upgrade to version 5.1.20

['mervin mecklenburg' via TiddlyWiki]

After I upgraded to version 5.1.20 from 5.1.16, the following code no 
longer works.

\define droppable-today(somevar)
<$action-listops $tiddler=<> $field="tags" 
$subfilter="-$(somevar)$"/>
\end



<$set name='somevar' value={{!!title}}>

<>

<$droppable actions=<>>Drop here

In the original version, the code performed two functions.  It created a 
list if titles of tiddlers with a certain tag, and the list could be 
resorted using drag and drop.  The bottom line removed the tag, and by 
doing so dropped items dragged to that point from the list.  Both of these 
functions no longer work following the upgrade.  Can anyone explain why?
